Interconnection Agreement

 Exhibit 10.52 
 INTERCONNECTION AGREEMENT 
 This Interconnection Agreement (“Agreement”) is entered into by
and between Sprint Spectrum, L.P., d/b/a Sprint PCS, with offices located at 6200 Sprint Parkway, Overland Park, Kansas (“Sprint”) and Neutral Tandem, Inc., with offices located at 2 North LaSalle Street, Suite 1615, Chicago, IL 60602
(“Neutral Tandem”). 
 WHEREAS, SPRINT is a Commercial Mobile Radio Services (“CMRS”) provider holding licenses to
operate from the Federal Communications Commission throughout the United States; and 
 WHEREAS, Neutral Tandem is a provider of transiting
services to telecommunication companies interconnecting with its tandem facilities in various locations; and 
 WHEREAS, Sprint and Neutral
Tandem wish to establish the terms and conditions for the interconnection of Sprint’s network to Neutral Tandem in any MTA in which both carriers operate; and 
 WHEREAS Neutral Tandem and Sprint desire to provide for the exchange of traffic between telecommunication companies interconnected with Neutral Tandem and using Neutral Tandem as a transit service provider.

 NOW THEREFORE, for and in consideration of the foregoing premises and other good and valuable consideration, the Parties agree to follow:

 1. Term of Agreement. This Agreement shall become effective upon execution of the Agreement by both Parties and have an initial term of one year.
Unless renegotiated pursuant to Section 6 herein, this Agreement shall automatically renew for successive one (1) year periods. Upon completion of the initial term, either party may terminate this agreement upon (60) sixty days prior
notice. 
 2. Definition of “Local Traffic”. Telecommunications traffic exchanged between a local exchange carrier and a CMRS provider that,
at the beginning of the call, originates and terminates within the same Major Trading Area, as defined in 47 C.F.R. §24.202(a). 
 3. Definition of a
“Mobile Switching Center” or “MSC”. A switch that performs, among other things, the switching of calls between and among its End User Customers and the End User Customers of other mobile or landline networks. The MSC is used
to interconnect Trunk circuits with Tandem switches and/or other MSCs. The MSC also coordinates inter-cell and inter-system call hand-offs and records all system traffic for analysis and billing. 
 4. Definition of “Transiting Traffic”. Traffic between two parties, one of which is not a Party to this Agreement, carried by a Party that neither
originates nor terminates that traffic on its network while acting as an intermediary.

separately with the Commission

 5. Exchange of Traffic: Only Local Traffic originated by customers of Neutral Tandem shall be delivered to Sprint
under this Agreement. Sprint may deliver Local Traffic destined to customers of Neutral Tandem under the compensation provisions below. 
 6. Compensation
for Call Transport and Termination: Neutral Tandem will allow for and SPRINT will terminate Local Traffic without compensation from Neutral Tandem for the term of this Agreement. By accepting Local Traffic from Neutral Tandem without
compensation from Neutral tandem, Sprint in no way waives it right to compensation for such traffic from the originating carrier. 
 7. Compensation for
Transit Traffic: Neutral Tandem agrees to accept Transiting Traffic from Sprint and deliver such Transiting Traffic to third parties interconnected with the Neutral Tandem tandem (“Transit Service”). Neutral Tandem shall provide Sprint
Transit Service pursuant to the applicable Neutral Tandem tariffs, but in the case of any inconsistency, this Agreement, including the attached Pricing Schedules, shall take precedence over any applicable tariff. Each Party acknowledges Sprint shall
pay Neutral Tandem a transit service charge as set forth in the Pricing Schedule attached hereto for traffic originated by Sprint and delivered to Neutral Tandem for transport to a third party carrier interconnected to the Neutral Tandem tandem. As
the Parties agree to a Pricing Schedule for additional markets, those will be added to and be part of this Agreement. Sprint shall not be responsible, and Neutral Tandem shall not bill Sprint, for Transit Traffic originated by third party carriers
interconnected to Neutral Tandem’s tandem facilities and delivered to Sprint. 
 8. Facility Compensation: Neutral Tandem shall be responsible
for all facilities and transport of Local Traffic including, but not limited to, any muxing, port, or termination costs associated with delivering Local Traffic to or from Sprint’s MSC to or from Neutral Tandem’s tandem location.

 9. Records Exchange: Neutral Tandem shall pass the call detail information required to permit billing of reciprocal compensation charges on all
calls originating from carriers interconnected to the Neutral Tandem tandem and terminating traffic to Sprint. If a carrier interconnected with Neutral Tandem does not generate sufficient call records to permit such billing, Neutral Tandem will
provide such information at not cost to Sprint. 
 10. Network Maintenance: The Parties will work cooperatively to install and maintain a reliable
network. The Parties will exchange appropriate information (e.g., maintenance contact numbers, network information, information required to comply with law enforcement and other security agencies of the government, etc.) to achieve
this desired reliability, subject to the confidentiality provisions herein. Neutral Tandem will provide non-discriminatory maintenance intervals that are consistent with the like type services which it provides to itself. 
 11. Network Management: 
  

	 	11.1	Neutral Tandem agrees too only pass traffic according to NPA/NXXs they have screened and sized trunks appropriately for. 

 *** Confidential information redacted and filed separately with the Commission

	 	11.2	Each Party shall provide a 24-hour contact number for network traffic management issues to the other’s surveillance management center. 

  

	 	11.3	Neither Party will use any service provided under this Agreement in a manner that interferes with third parties in the use of their service, prevents third parties from using their
service, impairs the quality of service to other carriers or to either party’s End User Customers. Either party will provide the other Party immediate notice of said impairment. 

  

	 	11.4	The characteristics and methods of operation of any circuits, facilities or equipment of either Party or that of a third party in conjunction with either Party’s facilities,
shall not materially interfere with or impair service over any facilitates of the other Party, its Affiliate companies or its connecting and concurring carriers involved in its services, cause damage to their plant, impair the privacy of any
communications carrier over their facilities or create electrical hazards to the employees of any of them or the public, or malfunction of either Party’s billing equipment. If either Party causes an Impairment of Service, as set forth in this
Section, the Party whose network or service is being impaired (the “Impaired Party”) shall promptly notify the Party causing the Impairment of Service (the “Impairing Party”) of the nature and location of the problem. The
Impaired Party shall advise the Impairing Party that, unless promptly rectified, a temporary discontinuance of the use of any circuit, facility or equipment may be required. The impairing Party and the Impaired Party agree to work together to
attempt to promptly resolve the Impairment of Service. If the Impairing Party is unable to promptly remedy the Impairment of Service, the Impaired Party may temporarily discontinue use of the affected circuit, facility or equipment.

 12. Trunk Servicing. If a Trunk Group is under 75% of centum call seconds capacity on a monthly average basis for each month of any
three consecutive months period, either party may request the issuance of an order to resize the Trunk Group which shall be left with not less than 25% excess capacity. If Neutral Tandem adds capacity in anticipation of growth beyond three months,
the parties agree to meet and discuss prior to deciding to resize the trunk group. SPRINT may agree to extend the period of underutilization if Neutral Tandem can demonstrate the capacity need. 
 13. SS7. SS& Out of Band Signaling (CCS/SS7) shall be the signaling of choice where technically feasible for both Parties. 
 14. Nondisclosure. The Parties to this Agreement anticipate and recognize that they will exchange or come into possession of data about each other’s
customers and each other’s business as a result of this Agreement. Each Party agrees 1) to treat all such data as strictly confidential and 2) to use such data only for the purposes of performance under this Agreement. All customer data will be
subject to this Section, whether or not designated confidential. The foregoing shall not apply to information in the public domain.

 15. Resolution of Disputes. Each Party to this Agreement will appoint a good faith representative to resolve any
dispute arising under this Agreement. 
 16. Compliance. The Parties hereto agree to comply with all current Federal and State laws and regulations
concerning the services provided under this Agreement. 
 17. Complete Terms. This Agreement constitutes the entire Agreement between the Parties. The
Parties agree to negotiate in good faith any issues related to the furnishing of services under this Agreement arising during the course of performance but are not otherwise included in this Agreement. 
 18. Change in Law. The parties shall comply with any applicable orders, rules or regulations of the FCC, appropriate Commissions and federal and state law during
the term of this Agreement. If there is a material change in law regarding the subject matter of this Agreement, either party may require negotiation of new terms and conditions to conform this agreement to that change in law.

 Page 1Addendum to Standard Purchase and License Terms

 EXHIBIT 10.54 
 ADDENDUM TO STANDARD PURCHASE AND LICENSE TERMS 
 Addendum dated as of August 17, 2006, between
Neutral Tandem, Inc. (“NT”) and Sonus Networks, Inc. (“Sonus”), to the Standard Purchase and License Terms, dated January 10, 2005 (the “Agreement”). 
 1. Quarterly Purchase Commitments. 
 (a) NT agrees to make minimum quarterly purchases (the “Quarterly Commitments”) as follows: 
  

					
	 Q3 2006
	  	$	    [	***]
	 Q4 2006
	  	$	    [	***]
	 Q1 2007
	  	$	    [	***]
	 Q2 2007
	  	$	    [	***]
	 Q3 2007
	  	$	     [	***]
	 Q4 2007
	  	$	     [	***]

 (b) To satisfy each Quarterly Commitment,
NT will issue purchase orders equal to or greater than the Quarterly Commitment no later than the tenth day of the second month of the quarter (“Order Date”). The purchase orders will allow for shipment no later than the 25th day of the third month of the quarter. The exception to this requirement is Q3 2006, for which the Order Date will be September 15, 2006, with shipment
to occur no later than December 15, 2006, and Q4 2006, for which the Order Date will be December 15, 2006, with shipment to occur no later than February 15, 2007. 
 2. Annual Purchase Commitments. 
 (a)
NT agrees to make minimum annual purchases (the “Annual Commitments”) as follows: 
  

					
	 Calendar 2008
	  	$	    [	***]
	 Calendar 2009
	  	$	    [	***]
	 Calendar 2010
	  	$	    [	***]
	 Calendar 2011
	  	$	    [	***]

 (b) To satisfy each Annual Commitment, NT
must (i) issue purchases orders for at least 40% of the Annual Commitment no later than an Order Date of April 25th of the applicable year, with
shipment to occur no later than June 25th, and (ii) must issue purchase orders for the balance of the Annual Commitment no later than an Order
Date of October 25th, with shipment to occur no later than December 25th. In the event Sonus delays any shipment beyond December 25th but makes the shipment prior to December 31st, such shipments will count towards meeting the Annual Commitment for that year. 
 3. Overages; Exclusions. 
 (a)
Purchases in excess of any commitment (“Overage”) will be credited toward fulfillment of the next purchase period’s commitment. Overages will be cumulative, and if an Overage exceeds the next purchase period’s commitment, the
Overage will continue to carry 
  

 *** Confidential information redacted and filed separately with the Commission 

 over for future purchase periods until the amount of the Overage is fully exhausted (including carrying over from year to
year). In the event at any point during the term of this Addendum, NT meets its total five-year obligation (i.e., purchases and takes delivery of at least $[***] of product in accordance with this Addendum), then NT will have satisfied its
obligations under this Addendum. 
 (b) All Sonus hardware and software products will count toward meeting the purchase commitments, except
for (i) call control elements (including the PSX, SGX, Sun products, Ulticom, and RAID) and (ii) any other third-party hardware and software resold by Sonus. Maintenance and services are also excluded from this calculation. 
 4. Pricing. 
 (a) Provided NT
continues to meet all applicable commitments during the term of this Addendum, NT’s pricing will be as set forth in Attachment A in the column entitled “Volume Pricing.” 
 (b) There are two scenarios under which NT’s pricing will revert to the pricing in the “Standard Pricing” column in Attachment A:

  

	 	(1)	during the years 2006 and 2007, if in any one quarter NT submits purchase orders by the Order Date but in an amount less than the Quarterly Commitment, and fails to make up the
shortfall by the Order Date in the subsequent quarter. (For example, if the shortfall in a quarter is $[***], in the next quarter NT must exceed the applicable Quarterly Commitment by at least $[***].) 

  

	 	(2)	during the years 2008-2011, if NT fails to meet any Order Date and/or shipment requirement described in Section 2(b) above. 

 (c) If any of the scenarios in Section 4(b) occur, then: 
 (i) during 2006-2007, for any purchase orders which have already shipped during the then-current quarter (i.e., the quarter following the quarter in which the commitment was originally missed), Sonus will invoice NT
for the difference between the Volume Pricing and the Standard Pricing (the “Pricing Differential”). Sonus will not invoice NT for the Pricing Differential for product shipped during the quarter in which the commitment was originally
missed; 
 (ii) during 2008-2011, Sonus will invoice NT for the Pricing Differential
for any purchase orders which shipped during the period in which it failed to meet either the Order Date requirement or the shipment requirement (i.e., either Jan 1 - June 30th or July 1- Dec 31 of that year); 
 (iii) for purchase orders submitted but not shipped during
the relevant period(s), NT will revise and reissue the purchase orders to incorporate the Standard Pricing; and 
 (iv) NT’s pricing for
all subsequent purchases under this Addendum will be at such Standard Pricing. 
 *** Confidential information redacted and filed
separately with the Commission 
  

 2 

 (d) Sonus agrees that the prices set forth in Attachment A are no higher than the prices offered to
Sonus’ similarly-situated customers for similar quantities of Products under similar terms and conditions (taking into account, without limitation, revenue and/or volume commitments, product applications and configurations, delivery schedules,
total purchases and deployments, and payment terms). 
 5. Product Shortages. 
 If Sonus fails to meet a shipment date due to product shortages, then the order will still count towards satisfying the commitment for the applicable
period. Sonus will use best efforts to notify NT of any shortages prior to the applicable order date. However, if Sonus fails to provide such notice, NT will still be required to meet the applicable commitment. 
 6. Maintenance. 
 If NT submits new
purchase orders prior to December 15, 2006 such that NT’s lifetime aggregate purchases total at least $[***], NT will qualify for a maintenance rate of [***]% for the 2007 renewal and for new purchases made in 2007. This rate will take
effect upon the maintenance renewal date. Otherwise, NT’s annual maintenance rate shall be [***]%.  
 7. Press Announcement.

 Sonus and NT agree to a joint press release announcing the replacement of a quarter of a million circuit switch ports with the Sonus
solution in NT’s four largest markets. The parties will mutually agree on the content and date of the release. 
 8. Term.

 This Addendum will expire on December 31, 2011, and will automatically renew on a quarter-to-quarter basis, unless either party
notifies the other party in writing of its desire to terminate this Addendum no less than thirty (30) days prior to the start of the next quarter. 
 9. Miscellaneous. 
 Capitalized terms used in this Addendum but not defined herein will have the
respective meanings ascribed to such terms in the Agreement. In the event of any conflict between the terms of this Addendum and the terms of the Agreement (or any previous amendments), this Addendum shall control. Except as modified by this
Addendum, the Agreement shall remain in full force and effect.
