Subpart A—General
§ 61.1 Purpose and application.
     (a) The purpose of this part is to prescribe the framework for the initial establishment of and subsequent
         revisions to tariff publications.

     (b) Tariff publications filed with the Commission must conform to the rules in this part and with Commission
         rules regarding the payment of statutory charges (see subpart G of part 1 of this title) and the use of FCC
         Registration Numbers (FRNs) (see subpart W of part 1 of this title). Failure to comply with any provisions
         of these rules may be grounds for rejection of the non-complying publication, a determination that it is
         unlawful or other action. Where an FRN has been omitted from a cover letter or transmittal accompanying
         a tariff publication filed under this part or the FRN included in that letter is invalid, the submitting carrier or
         carrier representative shall have ten (10) business days from the date of filing to amend the cover letter or
         transmittal to include a valid FRN. If within that ten (10) business day period, the carrier or carrier
         representative amends the cover letter or transmittal to include a valid FRN, that FRN shall be deemed to
         have been included in the letter as of its original filing date. If, after the expiration of the ten (10) business
         day period, the cover letter or transmittal has not been amended to include a valid FRN, the related tariff
         publication may be rejected if it has not yet become effective, declared unlawful if it has become effective,
         or subject to other action.

     (c) No carrier required to file tariffs may provide any interstate or foreign communication service until every
         tariff publication for such communication service is on file with the Commission and in effect.

[49 FR 40869, Oct. 18, 1984, as amended at 66 FR 47896, Sept. 14, 2001]

§ 61.2 General tariff requirements.
     (a) In order to remove all doubt as to their proper application, all tariff publications must contain clear and
         explicit explanatory statements regarding the rates and regulations.

     (b) Tariff publications must be delivered to the Commission free from all charges, including claims of
         postage.

     (c) Tariff publications will not be returned.

Tariffs

§ 61.3 Definitions.
     (a) Act. The Communications Act of 1934 (48 Stat. 1004; 47 U.S.C. chapter 5), as amended.

     (b) Actual Price Index (API). An index of the level of aggregate rate element rates in a basket, which index is
         calculated pursunt to § 61.46.

     (c) Association. This term has the meaning given it in § 69.2(d).

     (d) Average Price Cap CMT Revenue per Line month.

           (1) Price Cap CMT Revenue (as defined in § 61.3(cc)) per month as of July 1, 2000 (adjusted to remove
               Universal Service Contributions assessed to local exchange carriers pursuant to § 54.702 of this
               chapter) using 2000 annual filing base period demand, divided by the 2000 annual filing base period
               demand. In filing entities with multiple study areas, if it becomes necessary to calculate the Average
               Price Cap CMT Revenue per Line month for a specific study area, then the Average Price Cap CMT
               Revenue per Line month for that study area is determined as follows, using base period demand
               revenues (adjusted to remove Universal Service Contributions assessed to Local Exchange Carriers
               pursuant to § 54.702 of this chapter), Base Factor Portion (BFP) and 2000 annual filing base period
               lines:

                Average Price Cap CMT Revenue per Line Month in a study area = Price Cap CMT Revenue × (BFP in
                the study area ÷ (BFP in the Filing Entity) ÷ (Lines in the study area.

           (2) Nothing in this definition precludes a price cap local exchange carrier from continuing to average
               rates across filing entities containing multiple study areas, where permitted under existing rules.

           (3) Average Price Cap CMT Revenues per Line month may be adjusted after July 1, 2000 to reflect
               exogenous costs pursuant to § 61.45(d).

           (4) Average Price Cap CMT Revenues per Line month may also be adjusted pursuant to § 61.45
               (b)(1)(iii).

     (e) Average Traffic Sensitive Charge.

           (1) The Average Traffic Sensitive Charge (ATS charge) is the sum of the following two components:

                 (i)   The Local Switching (LS) component. The LS component will be calculated by dividing the
                       proposed LS revenues (End Office Switch, LS trunk ports, Information Surcharge, and signalling
                       transfer point (STP) port) by the base period LS minutes of use (MOUs); and

                 (ii) The Transport component. The Transport component will be calculated by dividing the
                      proposed Transport revenues (Switched Direct Trunk Transport, Signalling for Switched Direct
                      Trunk Transport, Entrance Facilities for Switched Access traffic, Tandem Switched Transport,
                      Signalling for Tandem Switching and residual per minute Transport Interconnection Charge
                      (TIC) pursuant to § 69.155 of this chapter) by price cap local exchange carrier only base period
                      MOUs (including meet-point billing arrangements for jointly-provided interstate access by a
                      price cap local exchange carrier and any other local exchange carrier).

           (2) For the purposes of determining whether the ATS charge has reached the Target Rate as set forth in
               § 61.3(qq), the calculations should include all the relevant revenues and minutes for services
               provided under generally available price cap tariffs.

     (f) Band. A zone of pricing flexibility for a service category, which zone is calculated pursuant to § 61.47.

    (bbb) Access Stimulation.

           (1) A Competitive Local Exchange Carrier serving end user(s) or an IPES Provider serving end user(s)
               engages in Access Stimulation when it satisfies either paragraph (bbb)(1)(i) or (ii) of this section;
               and a rate-of-return local exchange carrier serving end user(s) engages in Access Stimulation when
               it satisfies either paragraph (bbb)(1)(i) or (iii) of this section.

                 (i)   The rate-of-return local exchange carrier, Competitive Local Exchange Carrier, or IPES Provider:

                       (A) Has an access revenue sharing agreement, whether express, implied, written or oral, that,
                           over the course of the agreement, would directly or indirectly result in a net payment to the
                           other party (including affiliates) to the agreement, in which payment by the rate-of-return
                           local exchange carrier, Competitive Local Exchange Carrier, or IPES Provider is based on
                           the billing or collection of access charges from interexchange carriers or wireless carriers.
                           When determining whether there is a net payment under this rule, all payments, discounts,
                           credits, services, features, functions, and other items of value, regardless of form, provided
                           by the rate-of-return local exchange carrier, Competitive Local Exchange Carrier, or IPES
                           Provider to the other party to the agreement shall be taken into account; and

                       (B) Has either an interstate terminating-to-originating traffic ratio of at least 3:1 in an end
                           office or equivalent in a calendar month, or has had more than a 100 percent growth in
                           interstate originating and/or terminating switched access minutes of use in a month
                           compared to the same month in the preceding year for such end office or equivalent.

                 (ii) A Competitive Local Exchange Carrier or IPES Provider has an interstate terminating-to-
                      originating traffic ratio of at least 6:1 in an end office or equivalent in a calendar month.

                (iii) A rate-of-return local exchange carrier has an interstate terminating-to-originating traffic ratio of
                      at least 10:1 in an end office or equivalent in a three-calendar month period and has 500,000
                      minutes or more of interstate terminating minutes-of-use per month in the same end office in
                      the same three-calendar month period. These factors will be measured as an average over the
                      three-calendar month period.

           (2) A Competitive Local Exchange Carrier serving end user(s), or an IPES Provider serving end user(s),
               that has engaged in Access Stimulation will continue to be deemed to be engaged in Access
               Stimulation until: For a carrier or provider engaging in Access Stimulation as defined in paragraph
               (bbb)(1)(i) of this section, it terminates all revenue sharing agreements covered in paragraph
               (bbb)(1)(i) of this section and does not engage in Access Stimulation as defined in paragraph
               (bbb)(1)(ii) of this section; and for a carrier or provider engaging in Access Stimulation as defined in
               paragraph (bbb)(1)(ii) of this section, its interstate terminating-to-originating traffic ratio for an end
               office or equivalent falls below 6:1 for six consecutive months, and it does not engage in Access
               Stimulation as defined in paragraph (bbb)(1)(i) of this section.

           (3) A rate-of-return local exchange carrier serving end user(s) that has engaged in Access Stimulation
               will continue to be deemed to be engaged in Access Stimulation until: For a carrier engaging in
               Access Stimulation as defined in paragraph (bbb)(1)(i) of this section, it terminates all revenue
               sharing agreements covered in paragraph (bbb)(1)(i) of this section and does not engage in Access
               Stimulation as defined in paragraph (bbb)(1)(iii) of this section; and for a carrier engaging in Access

                months, and it does not engage in Access Stimulation as defined in paragraph (bbb)(1)(i) of this
                section.

           (4) A local exchange carrier engaging in Access Stimulation is subject to revised interstate switched
               access charge rules under § 61.26(g) (for Competitive Local Exchange Carriers) or § 61.38 and §
               69.3(e)(12) of this chapter (for rate-of-return local exchange carriers).

           (5) In calculating the interstate terminating-to-originating traffic ratio at each end office or equivalent
               under this paragraph (bbb), each Competitive Local Exchange Carrier, rate-of-return local exchange
               carrier or IPES Provider shall include in such calculation only traffic traversing that end office or
               equivalent and going to and from any telephone number associated with an Operating Company
               Number that has been issued to such Competitive Local Exchange Carrier, rate-of-return local
               exchange carrier or IPES Provider. The term “equivalent” in the phrase “end office or equivalent”
               means “End Office Equivalent,” as defined in this section.

    (ccc) Intermediate Access Provider. The term means, for purposes of this part and §§ 51.914, 69.4(1), and
          69.5(b) of this chapter, any entity that provides terminating switched access tandem switching or

               section; or

           (2) A local exchange carrier delivering traffic to an IPES Provider engaged in Access Stimulation, as
               defined in paragraph (bbb) of this section; or

           (3) An IPES Provider engaged in Access Stimulation, as defined in paragraph (bbb) of this section, where
               the entity delivers calls directly to the IPES Provider.

    (ddd) Interexchange Carrier. The term means, for purposes of this part and §§ 69.3(e)(12)(iv) and 69.5(b) of this
          chapter, a retail or wholesale telecommunications carrier that uses the exchange access or information
          access services of another telecommunications carrier for the provision of telecommunications.

    (eee) IPES (Internet Protocol Enabled Service) Provider. The term means, for purposes of this part and §§
          51.914, 69.4(l) and 69.5(b) of this chapter, a provider offering a service that:

           (2) Requires a broadband connection from the user's location or end to end;

           (3) Requires internet Protocol-compatible customer premises equipment (CPE); and

           (4) Permits users to receive calls that originate on the public switched telephone network or that
               originate from an Internet Protocol service.

     (fff) End Office Equivalent. For purposes of this part and §§ 51.914, 69.3(e)(12)(iv) and 69.4(l) of this chapter,
           an End Office Equivalent is the geographic location where traffic is delivered to an IPES Provider for
           delivery to an end user. This location shall be used as the terminating location for purposes of calculating
           terminating-to-originating traffic ratios, as provided in this section. For purposes of the Access
           Stimulation Rules, the term “equivalent” in the phrase “end office or equivalent” means End Office

Subpart C—General Rules for Nondominant Carriers
§ 61.18 Scope.
The rules in this subpart apply to all nondominant carriers.

§ 61.19 Detariffing of international and interstate, domestic interexchange services.
     (a) Except as otherwise provided in paragraphs (b) through (e) of this section, or by Commission order,
         carriers that are nondominant in the provision of international and interstate, domestic interexchange
         services shall not file tariffs for such services.

     (b) Carriers that are nondominant in the provision of international and domestic, interstate, interexchange
         services are permitted to file tariffs for dial-around 1 + services. For the purposes of this paragraph, dial-
         around 1 + calls are those calls made by accessing the interexchange carrier through the use of that
         carrier's carrier access code.

     (c) Carriers that are nondominant in the provision of international and domestic, interstate, interexchange
         services are permitted to file a tariff for such services applicable to those customers who contact the
         local exchange carrier to designate an interexchange carrier or to initiate a change with respect to their
         primary interexchange carrier. Such tariff will enable the interexchange carrier to provide service to the
         customer until the interexchange carrier and the customer consummate a written agreement, but in no
         event shall the interexchange carrier provide service to its customer pursuant to such tariff for more than
         45 days.

     (d) Carriers that are nondominant in the provision of international inbound collect calls to the United States
         are permitted to file a tariff for such services.

     (e) Carriers that are nondominant in the provision of “on-demand” Mobile Satellite Services are permitted to
         file a tariff for such services applicable to those customers that have not entered into pre-existing service
         contracts designating a specific provider for such services.

§ 61.25 References to other instruments.
In addition to the cross-references permitted pursuant to § 61.74, a non-dominant carrier may cross-reference in its
tariff publication only the rate provisions of another carrier's FCC tariff publication, provided that the following
conditions are met:

     (a) The tariff being cross-referenced must be on file with the Commission and in effect;

     (b) The issuing carrier must specifically identify in its tariff the cross-referenced tariff by Carrier Name and
         FCC Tariff Number;

     (c) The issuing carrier must specifically identify in its tariff the rates being cross-referenced so as to leave no
         doubt as to the exact rates that will apply, including but not limited to any applicable credits, discounts,
         promotions; and

     (d) The issuing carrier must keep its cross-references current.

§ 61.26 Tariffing of competitive interstate switched exchange access services.
     (a) Definitions. For purposes of this section, the following definitions shall apply:

           (1) CLEC shall mean a local exchange carrier that provides some or all of the interstate exchange access
               services used to send traffic to or from an end user and does not fall within the definition of
               “incumbent local exchange carrier” in 47 U.S.C. 251(h).

           (2) Competing ILEC shall mean the incumbent local exchange carrier, as defined in 47 U.S.C. 251(h), that
               would provide interstate exchange access services, in whole or in part, to the extent those services
               were not provided by the CLEC.

           (3) Switched exchange access services shall include:

                 (i)   The functional equivalent of the ILEC interstate exchange access services typically associated
                       with the following rate elements: Carrier common line (originating); carrier common line
                       (terminating); local end office switching; interconnection charge; information surcharge;
                       tandem switched transport termination (fixed); tandem switched transport facility (per mile);
                       tandem switching;

                 (ii) The termination of interexchange telecommunications traffic to any end user, either directly or
                      via contractual or other arrangements with an affiliated or unaffiliated provider of
                      interconnected VoIP service, as defined in 47 U.S.C. 153(25), or a non-interconnected VoIP

                       service, as defined in 47 U.S.C. 153(36), that does not itself seek to collect reciprocal
                       compensation charges prescribed by this subpart for that traffic, regardless of the specific
                       functions provided or facilities used.

           (4) Non-rural ILEC shall mean an incumbent local exchange carrier that is not a rural telephone company
               under 47 U.S.C. 153(44).

           (5) The rate for interstate switched exchange access services shall mean the composite, per-minute rate
               for these services, including all applicable fixed and traffic-sensitive charges.

           (6) Rural CLEC shall mean a CLEC that does not serve (i.e., terminate traffic to or originate traffic from)
               any end users located within either:

                 (i)   Any incorporated place of 50,000 inhabitants or more, based on the most recently available
                       population statistics of the Census Bureau or

                 (ii) An urbanized area, as defined by the Census Bureau.

     (b) Except as provided in paragraphs (c), (e), and (g) of this section, a CLEC shall not file a tariff for its
         interstate switched exchange access services that prices those services above the higher of:

           (1) The rate charged for such services by the competing ILEC or

           (2) The lower of:

                 (i)   The benchmark rate described in paragraph (c) of this section or

                 (ii) In the case of interstate switched exchange access service, the lowest rate that the CLEC has
                      tariffed for its interstate exchange access services, within the six months preceding June 20,
                      2001.

     (c) The benchmark rate for a CLEC's switched exchange access services will be the rate charged for similar
         services by the competing ILEC. If an ILEC to which a CLEC benchmarks its rates, pursuant to this section,
         lowers the rate to which a CLEC benchmarks, the CLEC must revise its rates to the lower level within 15
         days of the effective date of the lowered ILEC rate.

     (d) Except as provided in paragraph (g) of this section, and notwithstanding paragraphs (b) and (c) of this
         section, in the event that, after June 20, 2001, a CLEC begins serving end users in a metropolitan
         statistical area (MSA) where it has not previously served end users, the CLEC shall not file a tariff for its
         exchange access services in that MSA that prices those services above the rate charged for such
         services by the competing ILEC.

     (e) Rural exemption. Except as provided in paragraph (g) of this section, and notwithstanding paragraphs (b)
         through (d) of this section, a rural CLEC competing with a non-rural ILEC shall not file a tariff for its
         interstate exchange access services that prices those services above the rate prescribed in the NECA
         access tariff, assuming the highest rate band for local switching. In addition to that NECA rate, the rural
         CLEC may assess a presubscribed interexchange carrier charge if, and only to the extent that, the
         competing ILEC assesses this charge. Beginning July 1, 2013, all CLEC reciprocal compensation rates for
         intrastate switched exchange access services subject to this subpart also shall be no higher than that
         NECA rate.

     (f) If a CLEC provides some portion of the switched exchange access services used to send traffic to or from
         an end user not served by that CLEC, the rate for the access services provided may not exceed the rate
         charged by the competing ILEC for the same access services, except if the CLEC is listed in the database

[64 FR 46588, Aug. 26, 1999]

§ 61.38 Supporting information to be submitted with letters of transmittal.
     (a) Scope. This section applies to dominant carriers whose gross annual revenues exceed $500,000 for the
         most recent 12 month period of operations or are estimated to exceed $500,000 for a representative 12
         month period. Incumbent Local Exchange Carriers serving 50,000 or fewer access lines in a given study
         area that are described as subset 3 carriers in § 69.602 of this chapter may submit Access Tariff filings
         for that study area pursuant to either this section or § 61.39. However, the Commission may require any
         issuing carrier to submit such information as may be necessary for a review of a tariff filing. This section
         (other than the preceding sentence of this paragraph) shall not apply to tariff filings proposing rates for
         services identified in § 61.42 (d), (e), and (g).

     (b) Explanation and data supporting either changes or new tariff offerings. The material to be submitted for a
         tariff change which affects rates or charges or for a tariff offering a new service, must include an
         explanation of the changed or new matter, the reasons for the filing, the basis of ratemaking employed,
         and economic information to support the changed or new matter.

           (1) For a tariff change the issuing carrier must submit the following, including complete explanations of
               the bases for the estimates.

                 (i)   A cost of service study for all elements for the most recent 12 month period;

                 (ii) A study containing a projection of costs for a representative 12 month period;

                (iii) Estimates of the effect of the changed matter on the traffic and revenues from the service to
                      which the changed matter applies, the issuing carrier's other service classifications, and the
                      carrier's overall traffic and revenues. These estimates must include the projected effects on the
                      traffic and revenues for the same representative 12 month period used in (b)(1)(ii) above.

           (2) For a tariff filing offering a new service, the issuing carrier must submit the following, including
               complete explanations of the bases for the estimates.

                 (i)   A study containing a projection of costs for a representative 12 month period; and

                 (ii) Estimates of the effect of the new matter on the traffic and revenues from the service to which
                      the new matter applies, the issuing carrier's other service classifications, and the issuing
                      carrier's overall traffic and revenues. These estimates must include the projected effects on the
                      traffic and revenues for the same representative 12 month period used in paragraph (b)(2)(i) of
                      this section.

           (3) [Reserved]

           (4) For a tariff that introduces a system of density pricing zones, as described in § 69.123 of this
               chapter, the issuing carrier must, before filing its tariff, submit a density pricing zone plan including,
               inter alia, documentation sufficient to establish that the system of zones reasonably reflects cost-
               related characteristics, such as the density of total interstate traffic in central offices located in the
               respective zones, and receive approval of its proposed plan.

           (1) Concurrently with the filing of any tariff change or tariff filing for a service not previously offered, the
               issuing carrier must file the working papers containing the information underlying the data supplied
               in response to paragraph (b) of this section, and a clear explanation of how the working papers relate
               to that information.

           (2) All statistical studies must be submitted and supported in the form prescribed in § 1.363 of this
               chapter.

     (d) Form and content of additional material to be submitted with certain rate increases. In the circumstances
         set out in paragraphs (d)(1) and (2) of this section, the issuing carrier must submit all additional cost,
         marketing and other data underlying the working papers to justify a proposed rate increase. The issuing
         carrier must submit this information in suitable form to serve as the carrier's direct case in the event the
         rate increase is set by the Commission for investigation.

           (1) Rate increases affecting single services or tariffed items.

                 (i)   A rate increase in any service or tariffed item which results in more than $1 million in additional
                       annual revenues, calculated on the basis of existing quantities in service, without regard to the
                       percentage increase in such revenues; or

                 (ii) A single rate increase in any service or tariffed item, or successive rate increases in the same
                      service or tariffed item within a 12 month period, either of which results in:

                       (A) At least a 10 percent increase in annual revenues from that service or tariffed item, and

                       (B) At least $100,000 in additional annual revenues, both calculated on the basis of existing
                           quantities in service.

           (2) Rate increases affecting more than one service or tariffed item.

                 (i)   A general rate increase in more than one service or tariffed item occurring at one time, which
                       results in more than $1 million in additional revenues calculated on the basis of existing
                       quantities in service, without regard to the percentage increase in such revenues; or

                 (ii) A general rate increase in more than one service or tariffed item occurring at one time, or
                      successive general rate increases in the same services or tariffed items occurring within a 12
                      month period, either of which results in:

                       (A) At least a 10 percent increase in annual revenues from those services or tariffed items,
                           and

                       (B) At least $100,000 in additional annual revenues, both calculated on the basis of existing
                           quantities in service.

     (e) Submission of explanation and data by connecting carriers. If the changed or new matter is being filed by
         the issuing carrier at the request of a connecting carrier, the connecting carrier must provide the data
         required by paragraphs (b) and (c) of this section on the date the issuing carrier files the tariff matter with
         the Commission.

     (f) Copies of explanation and data to customers. Concurrently with the filing of any rate for special
         construction (or special assembly equipment and arrangements) developed on the basis of estimated

§ 61.39 Optional supporting information to be submitted with letters of transmittal for Access
Tariff filings by incumbent local exchange carriers serving 50,000 or fewer access lines in a
given study area that are described as subset 3 carriers in § 69.602.
     (a) Scope. Except as provided in paragraph (g) of this section, This section provides for an optional method of
         filing for any local exchange carrier that is described as a subset 3 carrier in § 69.602 of this chapter,
         which elects to issue its own Access Tariff for a period commencing on or after April 1, 1989, and which
         serves 50,000 or fewer access lines in a study area as determined under § 36.611(a)(8) of this chapter.
         However, the Commission may require any carrier to submit such information as may be necessary for
         review of a tariff filing. This section (other than the preceding sentence of this paragraph) shall not apply
         to tariff filings of local exchange carriers subject to price cap regulation.

     (b) Explanation and data supporting tariff changes. The material to be submitted to either a tariff change or a
         new tariff which affects rates or charges must include an explanation of the filing in the transmittal as
         required by § 61.15. The basis for ratemaking must comply with the following requirements. Except as
         provided in paragraph (b)(5) of this section, it is not necessary to submit this supporting data at the time
         of filing. However, the incumbent local exchange carrier should be prepared to submit the data promptly
         upon reasonable request by the Commission or interested parties.

           (1) For a tariff change, the incumbent local exchange carrier that is a cost schedule carrier must
               propose Traffic Sensitive rates based on the following:

                 (i)   For the first period, a cost of service study for Traffic Sensitive elements for the most recent
                       12-month period with related demand for the same period.

                 (ii) For subsequent filings, a cost of service study for Traffic Sensitive elements for the total period
                      since the incumbent local exchange carrier's last annual filing, with related demand for the
                      same period.

           (2) For a tariff change, the incumbent local exchange carrier that is an average schedule carrier must
               propose Traffic Sensitive rates based on the following:

                 (i)   For the first period, the incumbent local exchange carrier's most recent annual Traffic Sensitive
                       settlement from the National Exchange Carrier Association pool.

                 (ii) For subsequent filings, an amount calculated to reflect the Traffic Sensitive average schedule
                      pool settlement the carrier would have received if the carrier had continued to participate,
                      based upon the most recent average schedule formulas approved by the Commission.

           (3) For a tariff change, the incumbent local exchange carrier that is a cost schedule carrier must
               propose Common Line rates based on the following:

                 (i)   For the first biennial filing, the common line revenue requirement shall be determined by a cost
                       of service study for the most recent 12-month period. Subscriber line charges shall be based on
                       cost and demand data for the same period. Carrier common line rates shall be determined by
                       the following formula:

     CCL MOU0 = carrier common line minutes of use for the 12-month period preceding the most recent 12-month
     period.

                 (ii) For subsequent biennial filings, the common line revenue requirement shall be determined by a
                      cost of service study for the most recent 24-month period. Subscriber line charges shall be
                      based on cost and demand data for the same period. Carrier common line rates shall be
                      determined by the following formula:

                 (i)   For the first biennial filings, the common line revenue requirement shall be determined by the
                       incumbent local exchange carrier's most recent annual Common Line settlement from the
                       National Exchange Carrier Association. Subscriber line charges shall be based on cost and
                       demand data for the same period. Carrier common line rates shall be determined by the
                       following formula:

     Where:

     And where:

     CCL Rev Req = carrier common line settlement for the most recent 12-month period;

     CCL MOU0 = carrier common line minutes of use for the 12-month period preceding the most recent 12-month
     period.

                 (ii) For subsequent biennial filings, the common line revenue requirement shall be an amount
                      calculated to reflect the average schedule pool settlements the carrier would have received if
                      the carrier had continued to participate in the carrier common line pool, based upon the average
                      schedule Common Line formulas developed by the National Exchange Carrier Association for
                      the most recent 24-month period. Subscriber line charges shall be based on cost and demand

           (5) For End User Common Line charges included in a tariff pursuant to this Section, the incumbent local
               exchange carrier must provide supporting information for the two-year historical period with its letter
               of transmittal in accordance with § 61.38.

     (c) Maximum allowable rate of return. Incumbent Local exchange carriers filing tariffs under this section are
         not required to comply with §§ 65.700 through 65.701 of this chapter, except with respect to periods
         during which tariffs were not subject to this section. The Commission may require any carrier to submit
         such information if it deems it necessary to monitor the carrier's earnings. However, rates must be
         calculated based on the incumbent local exchange carrier's prescribed rate of return applicable to the
         period during which the rates are effective.

     (d) Rates for a new service that is the same as that offered by a price cap local exchange carrier providing
         service in an adjacent serving area are deemed presumptively lawful, if the proposed rates, in the
         aggregate, are no greater than the rates established by the price cap local exchange carrier. Tariff filings
         made pursuant to this paragraph must include the following:

           (1) A brief explanation of why the service is like an existing service offered by a geographically adjacent
               price cap local exchange carrier; and

           (2) Data to establish compliance with this paragraph that, in aggregate, the proposed rates for the new
               service are no greater than those in effect for the same or comparable service offered by that same
               geographically adjacent price cap regulated local exchange carrier. Compliance may be shown
               through submission of applicable tariff pages of the adjacent carrier; a showing that the serving
               areas are adjacent; any necessary explanations and work sheets.

     (e) Average schedule companies filing pursuant to this section shall retain their status as average schedule
         companies.

     (f) On each page of cost support material submitted pursuant to this section, the issuing carrier shall
         indicate the transmittal number under which that page was submitted.

     (g) Engagement in Access Stimulation. A local exchange carrier otherwise eligible to file a tariff pursuant to
         this section may not do so if it is engaging in Access Stimulation, as that term is defined in § 61.3(bbb). A
         carrier so engaged must file interstate access tariffs in accordance with § 61.38 and § 69.3(e)(12) of this
         chapter.

§ 61.40 Private line rate structure guidelines.
     (a) The Commission uses a variety of tools to determine whether a dominant carrier's private line tariffs are
         just, reasonable, and nondiscriminatory. The dominant carrier's burden of cost justification can be
         reduced when its private line rate structures comply with the following five guidelines.

           (1) Rate structures for the same or comparable services should be integrated;

           (2) Rate structures for the same or comparable services should be consistent with one another;

47 CFR 61.40(a)(2) (enhanced display)                                                                      page 23 of 59

Tariffs

           (3) Rate elements should be selected to reflect market demand, pricing convenience for the carrier and
               customers, and cost characteristics; a rate element which appears separately in one rate structure
               should appear separately in all other rate structures;

           (4) Rate elements should be consistently defined with respect to underlying service functions and
               should be consistently employed through all rate structures; and

           (5) Rate structures should be simple and easy to understand.

     (b) The guidelines do not preclude a carrier, in a given case when a private line tariff does not comply with
         these guidelines, from justifying its departure from the guidelines and showing that its tariff is just,
         reasonable, and nondiscriminatory.

§ 61.41 Price cap requirements generally.
     (a) Sections 61.42 through 61.49 shall apply as follows:

           (1) [Reserved]

           (2) To such price cap local exchange carriers as specified by Commission order, and to all local
               exchange carriers, other than average schedule companies, that are affiliated with such carriers; and

           (3) On an elective basis, to local exchange carriers, other than those specified in paragraph (a)(2) of this
               section, that are neither participants in any Association tariff, nor affiliated with any such
               participants, except that affiliation with average schedule companies shall not bar a carrier from
               electing price cap regulation provided the carrier is otherwise eligible.

     (b) If a telephone company, or any one of a group of affiliated telephone companies, files a price cap tariff in
         one study area, that telephone company and its affiliates, except its average schedule affiliates, must file
         price cap tariffs in all their study areas.

     (c) Except as provided in paragraph (e) of this section, the following rules in this paragraph (c) apply to
         telephone companies subject to price cap regulation, as that term is defined in § 61.3(ee), which are
         involved in mergers, acquisitions, or similar transactions.

           (1) Any telephone company subject to price cap regulation that is a party to a merger, acquisition, or
               similar transaction shall continue to be subject to price cap regulation notwithstanding such
               transaction.

           (2) Where a telephone company subject to price cap regulation acquires, is acquired by, merges with, or
               otherwise becomes affiliated with a telephone company that is not subject to price cap regulation,
               the latter telephone company shall become subject to price cap regulation no later than one year
               following the effective date of such merger, acquisition, or similar transaction and shall accordingly
               file price cap tariffs to be effective no later than that date in accordance with the applicable
               provisions of this part 61.

           (3) Notwithstanding the provisions of § 61.41(c)(2), when a telephone company subject to price cap
               regulation acquires, is acquired by, merges with, or otherwise becomes affiliated with a telephone
               company that qualifies as an “average schedule” company, the latter company may retain its
               “average schedule” status or become subject to price cap regulation in accordance with § 69.3(i)(3)
               of this chapter and the requirements referenced in that section.

     (e) Notwithstanding the requirements of paragraphs (c) and (d) of this section, a telephone company subject
         to rate-of-return regulation may return lines acquired from a telephone company subject to price cap
         regulation to rate-of-return regulation, provided that the acquired lines will not be subject to average
         schedule settlements, and provided further that the telephone company subject to rate-of-return
         regulation may not for five years elect price cap regulation for itself, or by any means cause the acquired
         lines to become subject to price cap regulation.

               61.49 of this chapter, this basket shall be referred to as the “traffic-sensitive basket.”

           (3) A basket for trunking services as described in §§ 69.110, 69.111, 69.112, 69.125(b), 69.129, and

                       interstate interexchange services that are not classified as access services for the purpose of
                       part 69 of this chapter, such exchange carrier shall establish a fourth basket for such services.
                       For purposes of §§ 61.41 through 61.49, this basket shall be referred to as the “interexchange
                       basket.”

                 (ii) If a price cap local exchange carrier has implemented interLATA and intraLATA toll dialing parity
                      everywhere it provides local exchange services at the holding company level, that price cap
                      carrier may file a tariff revision to remove corridor and interstate intraLATA toll services from its

§ 61.43 Annual price cap filings required.
Price cap local exchange carriers shall submit annual price cap tariff filings that propose rates for the upcoming
tariff year, that make appropriate adjustments to their PCI, API, and SBI values pursuant to §§ 61.45 through 61.47,
and that incorporate new services into the PCI, API, or SBI calculations pursuant to §§ 61.45(g), 61.46(b), and
61.47(b) and (c). Price cap local exchange carriers may propose rate, PCI, or other tariff changes more often than
annually, consistent with the requirements of § 61.59.

                       “PCIt = PCIt − 1[1 + w[GDP-PI − X] + Z / R].”

                       PCIt − 1 = PCIt −1[1 + w[GDP-PI − X] + Z / R]
                 Where the terms in the equation are described:

                 GDP-PI = For annual filings only, the percentage change in the GDP-PI between the quarter ending six
                 months prior to the effective date of the new annual tariff and the corresponding quarter of the
                 previous year. For all other filings, the value is zero.

                 level prescribed in paragraphs (b)(1)(ii) and (iii) of this section. For the interexchange basket, for
                 annual filings only, the factor is set at the level prescribed in paragraph (b)(1)(v) of this section. For
                 the special access basket, for annual filings only, the factor is set at the level prescribed in paragraph

                Z = The dollar effect of current regulatory changes when compared to the regulations in effect at the
                time the PCI was updated to PCIt−1, measured at base period level of operations.

                Targeted Reduction = the actual possible dollar value of the (GDP-PI − X) reductions that will be
                targeted to the ATS Charge pursuant to § 61.45(i)(3). The reductions calculated by applying the
                (GDP-PI − X) portion of the formula to the CCL element within the CMT basket will contain the “g”
                component, as defined above.

                R = Base period quantities for each rate element “I”, multiplied by the price for each rate element “I”
                at the time the PCI was updated to PCIt − 1.

                w = R + Z, all divided by R (used for the traffic sensitive, trunking, and special access baskets).

                wix = R—(access rate in effect at the time the PCI was updated to PCIt − 1 * base period demand) + Z,
                all divided by R.

                PCIt = The new PCI value.

                PCIt −1 = the immediately preceding PCI value.

                 (ii) The X value applicable to the baskets specified in §§ 61.42(d)(1), (d)(2), and (d)(3), shall be
                      6.5%, to the extent necessary to reduce a tariff entity's ATS charge to its Target Rate as set
                      forth in § 61.3(qq). Once any price cap local exchange carrier tariff entity's ATS Charge is equal
                      to the Target Rate as set forth in § 61.3(qq) for the first time (the former NYNEX telephone
                      companies may be treated as a separate tariff entity), then, except as provided in paragraph
                      (b)(1)(iii) of this section, X is equal to GDP-PI and no further reductions will be mandated (i.e., if
                      applying the full X-factor reduction for a given year would reduce the ATS charge below the
                      Target Rate as set forth in § 61.3 (qq), the amount of X-factor reduction applied that year will be
                      the amount necessary to reach the Target Rate as set forth in § 61.3 (qq)). A filing entity does
                      not reach the Target Rate as set forth in § 61.3(qq) in any year in which it exercises an
                      exogenous adjustment pursuant to § 61.45(d)(vii). For companies with separate tariff entities
                      under a single price cap, the following rules shall apply:

                         (A) Targeting amounts as defined in § 61.45(i)(1)(i) shall be identified separately, using the
                             revenue for each of the tariff entities under the cap.

                         (B) Each tariff entity shall only be required to use the amount of targeting necessary to get to
                             the Target Rate as set forth in § 61.3 (qq).

                 (iii)

                         (A) Except as provided in paragraph (b)(1)(iii)(B) of this section, once the Tariff Entity's Target
                             Rate as set forth in § 61.3 (qq) is achieved, the X-factor for the CMT basket will equal GDP-
                             PI as long as GDP-PI is less than or equal to 6.5% and greater than 0%. If GDP-PI is greater
                             than 6.5%, and an entity has eliminated its CCL and multi-line business PICCs charges, the
                             X-factor for the CMT basket will equal 6.5%, and all End User Common Line charges, rates
                             and nominal caps, will be increased by the difference between GDP-PI and the 6.5% X-
                             factor. If GDP-PI is less than 0, the X-factor for the CMT basket will be 0.

                         shall be applied only to the trunking and traffic sensitive baskets to the extent necessary to
                         reduce the ATS charge to the Target Rate as set forth in § 61.3 (qq), and shall not be applied to
                         reduce the PCIs in any other basket or to reduce Average Price Cap CMT Revenue per Line

                      reductions, the reductions to Local Switching rates as a percentage of total X-factor reductions
                      must be greater than or equal to the percentage proportion of Local Switching revenues to the
                      total sum of revenues for Local Switching, Local Switching Trunk Ports, Signalling Transfer
                      Point Port Termination, Switched Direct Trunked Transport, Signalling for Switched Direct
                      Trunked Transport, Entrance Facilities for switched access traffic, Tandem Switched Transport,
                      and Signalling for Tandem Switching (i.e., Local Switching gets at least its proportionate share
                      of reductions).

           (3) After a price cap local exchange carrier reaches the Target Rate as set forth in § 61.3(qq), the ATS
               Rate will be recalculated each subsequent Annual Filing. This process will identify the new ATS
               Charge for the new base period level. Due to change in base period demand and inclusion of new
               services for that annual filing, the absolute level of a tariff entity's ATS Charge may change. The
               resulting new ATS Charge level will be what that tariff entity will be measured against during that
               base period. For example, if a company whose target is $0.0055 reached the Target Rate during the
               2000 annual filing, that level may change to $0.0058 in the 2001 annual filing due to change in
               demand and inclusion of new services. Therefore, it will be the $0.0058 average rate that the tariff
               entity will be measured against for all non-annual filings. Likewise, if that same company was at the
               Target Rate during the 2000 filing, that level may change to $0.0053 average rate in the 2001 annual
               filing due to change in demand and inclusion of new services. In that case, it will be at the $0.0053
               average rate that the tariff entity will be measured.

           (4) A company electing a $0.0095 Target Rate will, in the tariff year it reaches the Target Rate, apply any
               Targeted Revenue Differential remaining after reaching the Target Rate to reduce Average Price Cap
               CMT Revenue per Line month until the CCL charge is eliminated. In subsequent years, until the
               earlier of June 30, 2004 or when the CCL charge is eliminated, tariff filing entities with a Target Rate
               of $0.0095, or the portion of a filing entity consolidated pursuant to § 61.48(o) that, prior to such
               consolidation, had a Target Rate of $0.0095, will reduce Average Price Cap CMT Revenue per Line
               month according to the following method:

                 (i)   Filing entity calculates the maximum allowable carrier common line revenue, as defined in §
                       61.46(d)(1), that would be permitted in the absence of further adjustment pursuant to this
                       paragraph;

                 (ii) Filing entity identifies maximum amount of dollars available to reduce Average Price Cap CMT
                      Revenue per Line month by the following:

§ 61.46 Adjustments to the API.
     (a) Except as provided in paragraphs (d) and (e) of this section, in connection with any price cap tariff filing
         proposing rate changes, the price cap local exchange carrier must calculate an API for each affected
         basket pursuant to the following methodology:

           APIt = APIt-1[Σi vi (Pt/Pt-1)i]
     Where:

     APIt = the proposed API value,

     APIt-1 = the existing API value,

     Pt = the proposed price for rate element “i,”

     Pt-1 = the existing price for rate element “i,” and

     vi = the current estimated revenue weight for rate element “i,” calculated as the ratio of the base period demand
     for the rate element “i” priced at the existing rate, to the base period demand for the entire basket of services
     priced at existing rates.

     (b) New services subject to price cap regulation must be included in the appropriate API calculations under
         paragraph (a) of this section beginning at the first annual price cap tariff filing following completion of the
         base period in which they are introduced. This index adjustment requires that the demand for the new
         service during the base period must be included in determining the weights used in calculating the API.

     (c) Any price cap tariff filing proposing rate restructuring shall require an adjustment to the API pursuant to
         the general methodology described in paragraph (a) of this section. This adjustment requires the
         conversion of existing rates into rates of equivalent value under the proposed structure, and then the
         comparison of the existing rates that have been converted to reflect restructuring to the proposed
         restructured rates. This calculation may require use of carrier data and estimation techniques to assign
         customers of the preexisting service to those services (including the new restructured service) that will
         remain or become available after restructuring.

     (d) The maximum allowable carrier common line (CCL) revenue shall be computed pursuant to the following
         methodology:

           CCL = CMT−EUCL−Interstate Access Universal Service Support Mechanism Per Line−PICC
     Where:

     CMT = Price Cap CMT Revenue as defined in § 61.3(cc).

§ 61.47 Adjustments to the SBI; pricing bands.
     (a) In connection with any price cap tariff filing proposing changes in the rates of services in service
         categories, subcategories, or density zones, the carrier must calculate an SBI value for each affected
         service category, subcategory, or density zone pursuant to the following methodology:

           SBIt = SBIt-1[Σi vi(Pt/Pt−1)i]
     where

     SBIt = the proposed SBI value,

     SBIt-1 = the existing SBI value,

     Pt = the proposed price for rate element “i,”

     Pt-1 = the existing price for rate element “i,” and

     vi = the current estimated revenue weight for rate element “i,” calculated as the ratio of the base period demand
     for the rate element “i” priced at the existing rate, to the base period demand for the entire group of rate
     elements comprising the service category priced at existing rates.

     (b) New services that are added to existing service categories or subcategories must be included in the
         appropriate SBI calculations under paragraph (a) of this section beginning at the first annual price cap
         tariff filing following completion of the base period in which they are introduced. This index adjustment
         requires that the demand for the new service during the base period must be included in determining the
         weights used in calculating the SBI.

     (c) In the event that the introduction of a new service requires the creation of a new service category or
         subcategory, a new SBI must be established for that service category or subcategory beginning at the first
         annual price cap tariff filing following completion of the base period in which the new service is
         introduced. The new SBI should be initialized at a value of 100, corresponding to the service category or
         subcategory rates in effect the last day of the base period, and thereafter should be adjusted as provided
         in paragraph (a) of this section.

Tariffs

     (d) Any price cap tariff filing proposing rate restructuring shall require an adjustment to the affected SBI
         pursuant to the general methodology described in paragraph (a) of this section. This adjustment requires
         the conversion of existing rates in the rate element group into rates of equivalent value under the
         proposed structure, and then the comparison of the existing rates that have been converted to reflect
         restructuring to the proposed restructured rates. This calculation may require use of carrier data and
         estimation techniques to assign customers of the preexisting service to those services (including the new
         restructured service) that will remain or become available after restructuring.

     (e) Pricing bands shall be established each tariff year for each service category and subcategory within a
         basket. Each band shall limit the pricing flexibility of the service category, subcategory, as reflected in the
         SBI, to an annual increase of a specified percent listed in this paragraph, relative to the percentage change
         in the PCI for that basket, measured from the levels in effect on the last day of the preceding tariff year.
         For local exchanage carriers subject to price cap regulation as that term is defined in § 61.3(ee), there

Tariffs

                Revenue weight of a given group of services included in a zone category is the ratio of base period
                     demand for the given service rate elements included in the category priced at existing rates, to
                     the base period demand for the entire group of rate elements comprising the category priced at
                     existing rates.

                Special access zone date is the date on which a local exchange carrier tariff establishing divergent
                      special access rates in different zones, as described in § 69.123(c) of this chapter, becomes
                      effective.

                      switched transport rates in different zones, as described in § 69.123(d) of this chapter,
                      becomes effective.

                price cap local exchange carriers that have established density pricing zones pursuant to § 69.123
                of this chapter, and whose special access zone date and transport zone date occur on different

           (1) In the July 1, 2000 annual filing, price cap local exchange carriers will make an additional reduction to
               rates comprising ATS charge, and to associated SBI upper limits and PCIs. This reduction will be
               calculated to be the amount that would be necessary to achieve a total $2.1 billion reduction in
               carrier common line and ATS rates by all price cap local exchange carriers, compared with those
               rates as they existed on June 30, 2000 using 2000 annual filing base period demand.

                 (i)   The net change in revenue associated with Carrier Common Line Rate elements resulting from:

                       (A) The removal from access of price cap local exchange carrier contributions to the Federal
                           universal service mechanisms;

                       (B) Price cap local exchange carrier receipts of interstate access universal service support
                           pursuant to subpart J of part 54;

                       (C) Changes in End User Common Line Charges and PICC rates;

                       (D) Changes in Carrier Common Line charges due to GDP-PI − X targeting for $0.0095 filing
                           entities.

                 (ii) Reductions in Average Traffic Sensitive charges resulting from:

                       (A) Targeting of the application of the (GDP-PI − X) portion of the formula in § 61.45(b), and
                           any applicable “g” adjustments;

                       (B) The removal from access of price cap local exchange carrier contributions to the Federal
                           universal service mechanisms;

                       (C) Additional ATS charge reductions defined in paragraph (2) of this section.

           (2) Once the reductions in paragraph (l)(1)(i) and paragraphs (l)(1)(ii)(A) and (l)(1)(ii)(B) of this section
               are identified, the difference between those reductions and $2.1 billion is the total amount of
               additional reductions that would be made to ATS rates of price cap local exchange carriers. This
               amount will then be restated as the percentage of total price cap local exchange carrier Local
               Switching revenues as of June 30, 2000 using 2000 annual filing base period demand (“June 30
               Local Switching revenues”) necessary to yield the total amount of additional reductions and taking
               into account the fact that, if participating, a price cap local exchange carrier would not reduce ATS
               rates below its Target Rate as set forth in § 61.3(qq).Each price cap local exchange carrier then
               reduces ATS rate elements, and associated SBI upper limits and PCIs, by a dollar amount equivalent
               to the percentage times the June 30 Local Switching revenues for that filing entity, provided that no
               price cap local exchange carrier shall be required to reduce its ATS rates below its Target Rate as set
               forth in § 61.3(qq). Each price cap local exchange carrier can take its additional reductions against
               any of the ATS rate elements, provided that at least a proportional share must be taken against Local
               Switching rates.

     (m) Pooled Local Switching Revenues.

           (1) Price cap local exchange carriers are permitted to pool local switching revenues in their CMT basket
               under one of the following conditions.

                 (i)   Any price cap local exchange carrier that would otherwise have July 1, 2000 price cap
                       reductions as a percentage of Base Period Price Cap Revenues at the holding company level
                       greater than the industry wide total July 1, 2000 price cap revenue reduction as a percentage of
                       Base Period Price Cap Revenues may elect temporarily to pool the amount of the additional
                       reductions above 25% of the Local Switching element revenues necessary to yield that carrier's

                       proportionate share of a total $2.1 billion reduction in switched access usage rates on July 1,
                       2000. The basis of the reduction calculation will be R at PCIt-1 for the upcoming tariff year. The
                       percentage reductions per line amounts will be calculated as follows: (Total Price Cap Revenue
                       Reduction ÷ Base Period Price Cap Revenues)

                       Pooled local switching revenue for each filing entity within a holding company that qualifies
                       under this paragraph (i) will continue until such pooled revenues are eliminated under this
                       paragraph. Notwithstanding the provisions of § 61.45(b)(1), once the Average Traffic Sensitive
                       (ATS) rate reaches the applicable Target Rate as set forth in § 61.3(qq), the Targeted Revenue
                       Differential as defined in § 61.45(i) shall be targeted to reducing pooled local switching revenue
                       until the pooled local switching revenue is eliminated. Thereafter, the X-factor for these baskets
                       will be determined in accordance with § 61.45(b)(1).

                 (ii) Price cap local exchange carriers other than the Bell companies and GTE with at least 20% of
                      total holding company lines operated by companies that as of December 31, 1999 were
                      certified to the Commission as rural carriers, may elect to pool up to the following amounts:

                       (A) For a price cap holding company's predominantly non-rural filing entities (i.e., filing entities
                           within which more than 50% of all lines are operated by telephone companies other than
                           those that as of December 31, 1999 were certified to the Commission as rural telephone
                           companies), the amount of the additional reductions to Average Traffic Sensitive Charge
                           rates as defined in paragraph (l)(2) of this section, to the extent such reductions exceed
                           25% of the Local Switching element revenues (measured in terms of June 30, 2000 rates
                           times 1999 base period demand);

                       (B) For a price cap holding company's predominantly rural filing entities (i.e., filing entities with
                           greater than 50% of lines operated by telephone companies that as of December 31, 1999
                           were certified to the Commission as rural telephone companies), the amount of the
                           additional reductions to Average Traffic Sensitive Charge rates as defined in paragraph
                           (l)(2) of this section.

           (2) Allocation of Pooled Local Switching Revenue to Certain CMT Elements

                 (i)   The pooled local switching revenue for each filing entity is shifted to the CMT basket within
                       price caps. Pooled local switching revenue will not be included in calculations to determine the
                       eligibility for interstate access universal service funding.

                 (ii) Pooled local switching revenue will be capped on a revenue per line basis.

                (iii) Pooled local switching revenue is included in the total revenue for the CMT basket in calculating
                      the X-factor reduction targeted to the traffic sensitive rate elements, and for companies
                      qualified under paragraph (m)(1)(i) of this section, to pooled elements after the Average Traffic
                      Sensitive Charge reaches the target level. For the purpose of targeting X-factor reductions,
                      companies that allocate pooled local switching revenue to other filing entities pursuant to
                      paragraph (m)(2)(vii) of this section shall include pooled local switching revenue in the total
                      revenue of the CMT basket of the filing entity from which the pooled local switching revenue
                      originated.

                (iv) Pooled local switching revenue shall be kept separate from CMT revenue in the CMT basket.
                     CMT rate elements for each filing entity shall first be set based on CMT revenue per line without
                     regard to the presence of pooled local switching revenue for each filing entity.

                 (v) If the rates generated without regard to the presence of pooled local switching revenue for
                     multi-line business PICC and/or multi-line business SLC are below the nominal caps of $4.31
                     and $9.20, respectively, pooled amounts can be added to these rate elements to the extent
                     permitted by the nominal caps.

                (vi) Notwithstanding the provisions of § 69.152(k) of this chapter, pooled local switching revenue is
                     first added to the multi-line business SLC until the rate equals the nominal cap ($9.20) or the
                     pooled local switching revenue is fully allocated. If pooled local switching revenue remains
                     after applying amounts to the multi-line business SLC, notwithstanding the provisions of §
                     69.153 of this chapter, the remaining pooled local switching revenue may be added to the multi-
                     line business PICC until the rate equals the nominal cap ($4.31) or the pooled local switching
                     revenue is fully allocated. Unallocated pooled local switching revenue may still remain. For
                     companies pooling pursuant to paragraph (m)(1)(i) of this section, these unallocated amounts
                     may not be recovered from the CCL charge, the primary residential and single-line business
                     SLC, a non-primary residential SLC, or from CMT elements in any other filing entity.

                (vii) For companies pooling pursuant to paragraph (m)(1)(ii) of this section, pooled local switching
                      revenue that can not be allocated to the multi-line business PICC and multi-line business SLC
                      rates within an individual filing entity may not be recovered from the CCL charge, primary
                      residential and single-line business SLC or residential/single-line business SLC charges, but
                      may be allocated to other filing entities within the holding company, and collected by adding
                      these amounts to the multi-line business PICC and multi-line business SLC rates. The allocation
                      of pooled local switching revenue among filing entities will be re-calculated at each annual
                      filing. In subsequent annual filings, pooled local switching revenue that was allocated to
                      another filing entity will be reallocated to the filing entity from where it originated, to the full
                      extent permitted by the nominal caps of $9.20 and $4.31.

                (viii) Notwithstanding the provisions of § 69.152(k) of this chapter, these unallocated local switching
                       revenues that cannot be recovered fully pursuant to paragraph (m)(2)(vii) of this section are
                       first added to the multi-line business SLC of other filing entities until the resulting rate equals
                       the nominal cap ($9.20) or the pooled local switching revenue for the holding company is fully
                       allocated. If the pooled local switching revenue can be fully allocated to the multi-line business
                       SLC, the amount is distributed to each filing entity with a rate below the nominal cap ($9.20)
                       based on its below-cap multi-line business SLC revenue as a percentage of the total holding
                       company's below-cap multi-line business SLC revenue.

                (ix) If pooled local switching revenue remains after applying amounts to the multi-line business SLC
                     of all filing entities in the holding company, pooled local switching revenue may be added to the
                     multi-line business PICC of other filing entities. Notwithstanding the provisions of § 69.153 of
                     this chapter, the remaining pooled local switching revenue is distributed to each filing entity
                     with a rate below the nominal cap ($4.31) based on its below-cap multi-line business PICC
                     revenue as a percentage of the total holding company's below-cap multi-line business PICC
                     revenue.

                 (x) If pooled local switching revenue is added to the multi-line business SLC but not to the multi-
                     line business PICC for a filing entity that qualified to deaverage SLCs without regard to pooled
                     local switching revenue, the resulting SLC rates can still be deaveraged. Total pooled local
                     switching revenue is added to the deaveraged zone 1 multi-line business SLC rate until the per
                     line rate in zone 1 equals the rate in zone 2 or until the pooled local switching revenue is fully

     (n) Establishment of the special access basket, effective July 1, 2000.

           (1) On the effective date, the PCI value for the special access basket, as defined in § 61.42(d)(5) shall be
               equal to the PCI for the trunking basket on the day preceding the establishment of the special

                       SBIs and upper limits and remain in the trunking basket.

                 (ii) Audio/Video and Wideband will retain the SBIs and upper limits and be moved into the special
                      access basket.

                (iii) For Voice Grade, the SBIs and upper limits in both baskets will be equal to the SBIs and upper
                      limits in the existing trunking basket on the day preceding the establishment of the special
                      access basket. Voice Grade density zones in the trunking basket will retain their indices and
                      upper limits. Voice Grade density zones will be initialized in the special access basket when
                      services are first offered in them.

                (iv) For High Cap/DDS, DS1, and DS3 category and subcategories, the SBIs and upper limits in both
                     baskets will be equal to the SBIs and upper limits in the existing trunking basket on the day
                     preceding the establishment of the special access basket. SBIs and upper limits for services
                     that are in both combined density zones and either DTT/EF or special access density zones will
                     be calculated by using weighted averages of the indices in the affected zones.

                 (v) For each DTT/EF-related zone remaining in the trunking basket, the values will be calculated by
                     taking the sum of the products of the DTT/EF revenues times the DTT/EF index (or upper limit)
                     and the DTT/EF-related revenues in the combined zone times the combined index (or upper
                     limit), and dividing by the total DTT/EF-related revenues for that zone.

                (vi) For each special access-related zone in the special access basket, the values will be calculated
                     by taking the sum of the products of the special access revenues times the special access
                     index (or upper limit) and the special access-related revenues in the combined zone times the
                     combined index (or upper limit), and dividing by the total special access-related revenues for

         its indexes for those rates to the extent those sections are applicable to business data services, except
         that:

            (1) Exogenous costs associated with regulated services shall be allocated to business data services
                based on relative regulated business data services revenues, compared to regulated revenues and

         data services at different rates in different study areas.

     (f) A rate-of-return carrier offering business data services pursuant to this section may make a low-end

Tariffs

                 (i)   The page immediately following the title page must be designated as “Original page 1” and
                       captioned “Check Sheet.” When the original tariff is filed, the check sheet must show the
                       number of pages contained in the tariff. For example, “Page 1 to 150, inclusive, of this tariff are
                       effective as of the date shown.” When new pages are added, they must be numbered in
                       continuing sequence, and designated as “Original page ____ .” For example, when the original
                       tariff filed has 150 pages, the first page added after page 150 is to be designated as “Original
                       page 151,” and the foregoing notation must be revised to include the added pages.

                 (ii) Alternatively, the carrier is permitted to number its tariff pages, other than the check sheet, to
                      reflect the section number of the tariff as well as the page. For example, under this system,
                      pages in section 1 of the tariff would be numbered 1–1, 1–2, etc., and pages in section 2 of the
                      tariff would be numbered 2–1, 2–2, etc. Issuing carriers shall utilize only one page numbering
                      system throughout its tariff.

           (2) If pages are to be inserted between numbered pages, each such page must be designated as an
               original page and must bear the number of the immediately preceding page followed by an alpha or
               numeric suffix. For example, when two new pages are to be inserted between pages 44 and 45 of the
               tariff, the first inserted page must be designated as Original page 44A or 44.1 and the second
               inserted page as Original page 44B or 44.2. Issuing carriers may not utilize both the alpha and
               numeric systems in the same publication.

           (3)

                 (i)   When pages are revised, when new pages (including pages with letter or numeric suffix as set
                       forth above) are added to the tariff, or when supplements are issued, the check sheet must be
                       revised accordingly. Revised check sheets must indicate with an asterisk the specific pages
                       added or revised. In addition to the notation in (1), the check sheet must list, under the heading
                       “The original and revised pages named below (and Supplement No. ____) contain all changes
                       from the original tariff that are in effect on the date shown,” all original pages in numerical order
                       that have been added to the tariff and the pages which have been revised, including the revision
                       number. For example:

                              Page                            Number of revision except as indicated
                        Title           1st
                        1               *8th

                        151             Orig.

                       *New or Revised page.

                 (ii) On each page, the carrier shall indicate the transmittal number under which that page was
                      submitted.

           (4) Changes in, and additions to tariffs must be made by reprinting the page upon which a change or
               addition is made. Such changed page is to be designated as a revised page, cancelling the page
               which it amends. For example, “First revised page 1 cancels original page 1,” or “Second revised
               page 2 cancels first revised page 2,” etc. When a revised page omits rates or regulations previously

                 published on the page which it cancels, but such rates or regulations are published on another page,
                 the revised page must make specific reference to the page on which the rates or regulations will be
                 found. This reference must be accomplished by inserting a sentence at the bottom of the revised
                 page that states “Certain rates (or regulations) previously found on this page can now be found on
                 page ___.” In addition, the page on which the omitted material now appears must bear the
                 appropriate symbol opposite such material, and make specific reference to the page from which the
                 rates or regulations were transferred. This reference must be accomplished by inserting a sentence
                 at the bottom of the other page that states “Certain rates (or regulations) on this page formerly
                 appeared on page ____.”

            (5) Rejected pages must be treated as indicated in § 61.69.

     (d) Table of contents. The table of contents must contain a full and complete statement showing the exact
         location and specifying the page or section and page numbers, where information by subjects under
         general headings will be found. If a tariff contains so small a volume of matter that its title page or its
         interior arrangement plainly discloses its contents, the table of contents may be omitted.

     (e) Tariff User's guide. At its option, a carrier may include a section explaining how to use the tariff.

     (f) List of concurring carriers. This list must contain the exact name or names of carriers concurring in the
         tariff, alphabetically arranged, and the name of the city or town in which the principal office of every such
         carrier is located. If there are no concurring carriers, then the statement “no concurring carriers” must be
         made at the place where the names of the concurring carriers would otherwise appear. If the concurring
         carriers are numerous, their names may be stated in alphabetical order in a separate tariff filed with the
         Commission by the issuing carrier. Specific reference to such separate tariff by FCC number must be
         made in the tariff at the place where such names would otherwise appear.

     (g) List of connecting carriers. This list must contain the exact name or names of connecting carriers,
         alphabetically arranged, for which rates or regulations are published in the tariff, and the name of the city
         or town in which the principal office of every such carrier is located. If there are no connecting carriers,
         then the statement “no connecting carriers” must be made at the place where their names would
         otherwise appear. If connecting carriers are numerous, their names may be stated in alphabetical order in
         a separate tariff filed with the Commission by the issuing carrier. Specific reference to such separate tariff
         by FCC number must be made in the tariff at the place where such names would otherwise appear.

     (h) List of other participating carriers. This list must contain the exact name of every other carrier subject to
         the Act engaging or participating in the communication service to which the tariff or supplement applies,
         together with the name of the city or town in which the principal office of such carrier is located. If there is
         no such other carrier, then the statement “no participating carriers” must be made at the place where the
         names of such other carriers would otherwise appear. If such other carriers are numerous, their names
         may be stated in alphabetical order in a separate tariff filed with the Commission by the issuing carrier.
         Specific reference must be made in the tariff at the place where such names would otherwise appear. The
         names of concurring and connecting carriers properly listed in a tariff published by any other participating
         carrier need not be repeated in this list.

      (i)

            (1) Symbols, reference marks, abbreviations. The tariff must contain an explanation of symbols,
                reference marks, and abbreviations of technical terms used. The following symbols used in tariffs

                  (i)   When a change of the same character is made in all or in substantially all matter in a tariff, it
                        may be indicated at the top of the title page of the tariff or at the top of each affected page, in
                        the following manner: “All rates in this tariff are increases,” or, “All rates on this page are
                        reductions, except as otherwise indicated.”

                  (ii) When a change of the same character is made in all or substantially all matters on a page or
                       supplement, it may be indiated at the top of the page or supplement in the following manner: All
                       rates on this page (or supplement) are increases,” or, “All rates on this page (or supplement) are
                       reductions except as otherwise indicated.”

            (3) Items which have not been in effect 30 days when brought forward on revised pages must be shown
                as reissued, in the manner prescribed in § 61.54(i)(1). The number and original effective date of the
                tariff publication in which the matter was originally published must be associated with the reissued
                matter. Items which have been in effect 30 days or more and are brought forward without change on
                revised pages must not be shown as reissued items.

      (j)   Rates and general rules, regulations, exceptions and conditions. The general rules (including definitions),
            regulations, exceptions, and conditions which govern the tariff must be stated clearly and definitely. All
            general rules, regulations, exceptions or conditions which in any way affect the rates named in the tariff
            must be specified. A special rule, regulation, exception or condition affecting a particular item or rate
            must be specifically referred to in connection with such item or rate. Rates must be expressed in United
            States currency, per chargeable unit of service for all communication services, together with a list of all
            points of service to and from which the rates apply. They must be arranged in a simple and systematic
            manner. Complicated or ambiguous terminology may not be used, and no rate, rule, regulation, exception
            or condition shall be included which in any way attempts to substitute a rate, rule, regulation, exception or
            condition named in any other tariff.

     (k) References to other tariffs. Notwithstanding any other provisions in this section, tariff publications filed by
         a carrier may reference other tariff publications filed by that carrier or its affiliates.

§ 61.58 Notice requirements.
     (a) Every proposed tariff filing must bear an effective date and, except as otherwise provided by regulation,
         special permission, or Commission order, must be made on at least the number of days notice specified
         in this section.

           (1) Notice is accomplished by filing the proposed tariff changes with the Commission. Any period of
               notice specified in this section begins on and includes the date the tariff is received by the
               Commission, but does not include the effective date. If a tariff filing proposes changes governed by
               more than one of the notice periods listed below, the longest notice period will apply. In computing
               the notice period required, all days including Sundays and holidays must be counted.

           (2)

                 (i)   Local exchange carriers may file tariffs pursuant to the streamlined tariff filing provisions of
                       section 204(a)(3) of the Communications Act. Such a tariff may be filed on 7 days' notice if it
                       proposes only rate decreases. Any other tariff filed pursuant to section 204(a)(3) of the
                       Communications Act, including those that propose a rate increase or any change in terms and
                       conditions, shall be filed on 15 days' notice. Any tariff filing made pursuant to section 204(a)(3)
                       of the Communications Act must comply with the applicable cost support requirements
                       specified in this part.

                 (ii) Local exchange carriers may elect not to file tariffs pursuant to section 204(a)(3) of the
                      Communications Act. For dominant carriers, any such tariffs shall be filed on at least 16 days'
                      notice. For nondominant carriers, any such tariffs shall be filed on at least one days' notice.

                 (iii) Except for tariffs filed pursuant to section 204(a)(3) of the Communications Act, the Chief,
                       Wireline Competition Bureau, may require the deferral of the effective date of any filing made on
                       less than 120 days' notice, so as to provide for a maximum of 120 days' notice, or of such other
                       maximum period of notice permitted by section 203(b) of the Communications Act, regardless
                       of whether petitions under § 1.773 of this chapter have been filed.

           (3) Tariff filings proposing corrections or voluntarily deferring the effective date of a pending tariff
               revision must be made on at least 3 days' notice, and may be filed notwithstanding the provisions of
               § 61.59. Corrections to tariff materials not yet effective cannot take effect before the effective date
               of the original material. Deferrals must take effect on or before the current effective date of the
               pending tariff revisions being deferred.

           (4) This subsection applies only to dominant carriers. If the tariff publication would increase any rate or
               charge, or would effectuate and authorized discountinuance, reduction or other impairment of
               service to any customer, the offering carrier must inform the affected customers of the content of
               the tariff publication. Such notification should be made in a form appropriate to the circumstance,
               and may include written notification, personal contact, or advertising in newspapers of general
               circulation.

     (b) Tariffs for new services filed by price cap local exchange carriers shall be filed on at least one day's
         notice.

     (c) Contract-based tariffs filed by price cap local exchange carriers pursuant to § 69.727(a) of this chapter
         shall be filed on at least one day's notice.

           (1) A price cap local exchange carrier that is filing a tariff revision to remove its corridor or interstate
               intraLATA toll services from its interexchange basket pursuant to § 61.42(d)(4)(ii) shall submit such
               filing on at least fifteen days' notice.

               from its interexchange basket pursuant to § 61.42(d)(4)(ii) shall file subsequent tariff filings for
               corridor or interstate intraLATA toll services on at least one day's notice.

                 (ii) Tariffs filings involving new rates and regulations not previously filed at, from, to or via points on
                      new lines; at, from to or via new radio facilities; or for new points of radio communication.

                (iii) Tariff filings involving a change in the name of a carrier, a change in Vertical or Horizontal
                      coordinates (or other means used to determine airline mileages), a change in the lists of
                      mileages, a change in the lists of connecting, concurring or other participating carriers, text
                      changes, or the imposition of termination charges calculated from effective tariff provisions.
                      The imposition of termination charges does not include the initial filing of termination liability
                      provisions.

           (2) Tariff filings involving a change in rate structure, a new offering, or a rate increase must be made on

When a tariff publication is rejected by the Commission, its number may not be used again. This includes, but is not
limited to, such publications as tariff numbers or specific page revision numbers. The rejected tariff publication may
not be referred to as either cancelled or revised. Within five business days of the release date of the Commission's
Order rejecting such tariff publication, the issuing carrier shall file tariff revisions removing the rejected material,
unless the Commission's Order establishes a different date for this filing. The publication that is subsequently
issued in lieu of the rejected tariff publication must bear the notation:

     (e) Tariffs may reference other FCC tariffs that are in effect and on file with the Commission for purposes of
         determining mileage, or specifying the operating centers at which a specific service is available.

     (f) Tariffs may reference technical publications which describe the engineering, specifications, or other
         technical aspects of a service offering, provided the following conditions are satisfied:

           (1) The tariff must contain a general description of the service offering, including basic parameters and
               structural elements of the offering;

Tariffs

           (2) The technical publication includes no rates, regulatory terms, or conditions which are required to be
               contained in the tariff, and any revisions to the technical publication do not affect rates, regulatory

           (3) The tariff indicates where the technical publication can be obtained;

           (4) The referenced technical publication is publicly available before the tariff is scheduled to take effect;
               and

[76 FR 43216, July 20, 2011]

§ 61.87 Cancellation of tariffs.
     (a) An issuing carrier may cancel an entire tariff. Cancellation of a tariff automatically cancels every page and
         supplement to that tariff except for the canceling Title Page or first page.

           (1) If the existing service(s) will be provided under another carrier's tariff, then

                 (i)   The issuing carrier whose tariff is being canceled must revise the Title Page or the first page of
                       its tariff indicating that the tariff is no longer effective, or

                 (ii) The issuing carrier under whose tariff the service(s) will be provided must revise the Title Page
                      or first page of the tariff to be canceled, using the name and numbering shown in the heading
                      of the tariff to be canceled, indicating that the tariff is no longer effective. This carrier must also
                      file with the Commission the new tariff provisions reflecting the service(s) being canceled. Both
                      filings must be effective on the same date and may be filed under the same transmittal.

           (2) If a carrier canceling its tariff intends to cease to provide existing service, then it must revise the Title
               Page or first page of its tariff indicating that the tariff is no longer effective.

           (3) A carrier canceling its tariff, as described in this section, must comply with §§ 61.54(b)(1) and
               61.54(b)(5), as applicable.

         canceled tariff must show where all rates and regulations will be found except for paragraph (c) of this
         section. The Title Page or first page of the new tariff must indicate the name of the carrier and tariff
         number where the canceled material had been found.

     (c) When a carrier ceases to provide service(s) without a successor, it must cancel its tariff pursuant to the
         notice requirements of § 61.58, as applicable, unless otherwise authorized by the Commission.

§ 61.131 Scope.
Sections 61.132 through 61.136 apply to a carrier which must file concurrences reflecting rates and regulations for
through service provided in conjunction with other carriers and to a carrier which has chosen, as an alternative to
publishing its own tariff, to arrange concurrence in an effective tariff of another carrier. Limited or partial
concurrences will not be permitted.

§ 61.132 Method of filing concurrences.
A carrier proposing to concur in another carrier's effective tariff must deliver one copy of the concurrence to the
issuing carrier in whose favor the concurrence is issued. The concurrence must be signed by an officer or agent of
the carrier executing the concurrence, and must be numbered consecutively in a separate series from its FCC tariff
numbers. At the same time the issuing carrier revises its tariff to reflect such a concurrence, it must file one copy of
the concurrence electronically with the Commission in accordance with the requirements set forth in § 61.13
through § 61.17. The concurrence must bear the same effective date as the date of the tariff filing reflecting the
concurrence. Carriers shall file revisions reflecting concurrences in their tariffs on the notice period specified in §
61.58.

§ 61.134 Concurrences for through services.
An issuing carrier filing rates or regulations for through services between points on its own system and points on
another carrier's system (or systems), or between points on another carrier's system (or systems), must list all
concurring, connecting or other participating carriers as provided in § 61.54 (f), (g) and (h). A concurring carrier
must tender a properly executed instrument of concurrence to the issuing carrier. If rates and regulations of the
other carriers engaging in the through service(s) are not specified in the issuing carrier's tariff, that tariff must state
where the other carrier's rates and regulations can be found. Such reference(s) must contain the FCC number(s) of
the referenced tariff publication(s), the exact name(s) of the carrier(s) issuing such tariff publication(s), and must
clearly state how the rates and regulations in the separate publications apply.

[76 FR 43216, July 20, 2011]

§ 61.135 Concurrences for other purposes.
When an issuing carrier permits another carrier to concur in its tariff, the issuing carrier's tariff must state the
concurring carrier's rates and points of service.

§ 61.136 Revocation of concurrences.
A concurrence may be revoked by a revocation notice or cancelled by a new concurrence. A revocation notice or a
new concurrence, if less broad in scope than the concurrence it cancels, must bear an effective date not less than
45 days after its receipt by the Commission. A revocation notice is not given a serial number, but must specify the
number of the concurrence to be revoked and the name of the carrier in whose favor the concurrence was issued. It

Subpart I—Adoption of Tariffs and Other Documents of Predecessor Carriers
§ 61.171 Adoption notice.
When a carrier's name is changed, or its operating control transferred from one carrier to another in whole or in part,
the successor carrier must file tariff revisions to reflect the name change. The successor carrier may either
immediately reissue the entire tariff in its own name, or immediately file an adoption notice. Within 35 days of filing
an adoption notice, the successor must reissue the entire tariff in its own name. The reissued tariff must be
numbered in the series of the successor carrier, and must contain all original pages without changes in regulations
or rates. The transmittal letter must state the tariff is being filed to show a change in the carrier's name pursuant to
§ 61.171 of the Commission's Rules. The adoption notice, if used, must read as follows:

     The (Exact name of successor carrier or receiver) here adopts, ratifies and makes its own in every respect, all
     applicable tariffs and amendments filed with the Federal Communications Commission by (predecessor) prior

§ 61.172 Changes to be incorporated in tariffs of successor carrier.
When only a portion of properties is transferred to a successor carrier, that carrier must incorporate in its tariff the
rates applying locally between points on the transferred portion. Moreover, the predecessor carrier must
simultaneously cancel the corresponding rates from its tariffs, and reference the FCC number of the successor
carrier's tariff containing the rates that will thereafter apply.

Subpart J—Suspensions
§ 61.191 Carrier to file supplement when notified of suspension.
If an issuing carrier is notified by the Commission that its tariff publication has been suspended, the carrier must
