Illinois Administrative Code › Title 83 - PUBLIC UTILITIES › Part 725 - STANDARDS OF SERVICE APPLICABLE TO 9-1-1 EMERGENCY SYSTEMS › Subpart D - STANDARDS OF SERVICE › Section 725.410 - Telecommunications Carriers

Current through Register Vol. 48, No. 28, July 12, 2024
a) Each
				telecommunications carrier shall file tariffs under Section 13-900.1 of the Public
				Utilities Act for 9-1-1 telecommunications service to be applied to all services
				specific to 9-1-1 installations on the carrier's network side of the customer
				demarcation point.
b) Dedicated
				redundant facilities should be considered to be the standard method of providing all
				incoming 9-1-1 facilities and, when possible, employ diverse routing. 9-1-1 circuits
				and facilities shall be sufficient to complete 99% of all requests for emergency
				services during the average busy hour of the average busy day. In all cases, the
				9-1-1 network shall be provisioned to handle a minimum of two circuits and/or
				simultaneous calls, and shall use dedicated, diverse and/or redundant equipment,
				when available, in order to increase the survivability of the 9-1-1 network.
				Additionally, the Commission 9-1-1 Program Staff and/or 9-1-1 authority may, on an
				annual basis or in the event of a problem, request traffic studies or other
				documentation to verify that the standard is being met.
c) Coin-free dialing of the digits 9-1-1 shall be
				provided from all coin telephones within an exchange with 9-1-1 service.
d) The transmission grade of service on 9-1-1
				facilities using inter-exchange facilities shall be at least equivalent to the
				transmission grade of service specified in 83 Ill. Adm. Code
				730.520 or
				737.440 dealing
				with interoffice transmission objectives.
e) The transmission grade of service for the
				intra-exchange loop portion of any 9-1-1 facilities shall be at least equivalent to
				the transmission grade of service specified in 83 Ill. Adm. Code
				730.525 or
				737.630
				dealing with local loop transmission objectives.
f) When all 9-1-1 facilities are busy in the
				originating central office, the switching facility, when equipped to provide the
				function, shall route the caller to an announcement or busy tone. When an all trunks
				busy situation occurs in an intermediate switching facility, that switch shall, when
				equipped, route the caller to an appropriate backup or alternate answering location,
				announcement, or busy tone.
g) All
				telecommunications carriers shall arrange for each of their switching offices to
				accept the 9-1-1 code.
h)
				Telecommunications carrier's personnel shall notify the 9-1-1 authority a minimum of
				48 hours prior to performing any planned action that could adversely affect 9-1-1
				service.
i) Each telecommunications
				carrier shall adopt practices to minimize the possibility of service disruption on
				all facilities associated with 9-1-1 service to a 9-1-1 system. These practices will
				provide for facility guarding at all terminations with protective devices that will
				minimize accidental worker caused service interruption. These practices shall also
				contain procedures for physical identification of all 9-1-1 facilities with special
				warning tags and/or labels and identification of circuits in company
				records.
j) Each telecommunications
				carrier shall deliver 9-1-1 service elements for the provisioning and ongoing
				maintenance of the 9-1-1 systems as follows:
1)
				Provide database downloads and updates to the appropriate 9-1-1 system provider for
				each 9-1-1 system in which it has subscribers.
2) Adhere to acceptable and agreed upon standards
				for database record exchange as prescribed, at a minimum, by NENA Standard Data
				Formats For ALI Data Exchange, MSAG & GIS.
3) Process error corrections within 2 business
				days after receipt of an error report from the 9-1-1 system provider and/or 9-1-1
				authority.
4) Provision and connect its
				network to the appropriate 9-1-1 system provider. Nothing in this Section prohibits
				a telecommunications carrier from contracting with a third party provider who may
				connect its network to the appropriate 9-1-1 system provider for the transport of
				9-1-1 traffic. The network design must adhere to the engineering practices and
				default routing requirements specified in Section
				725.405(i)(11) and
				(22).
5) Not deliver emergency calls to operator
				services.
6) Provide maintenance and
				repair procedures, service and repair center contact information, maintain a
				restoration plan and perform call trace procedures to the 9-1-1 authority.
7) Comply and arrange for default routing
				requirements with the 9-1-1 system provider and the 9-1-1 authority.
8) Maintain a list of contact numbers for
				notifying the appropriate 9-1-1 system in the event of an outage or failure of a
				9-1-1 system.
9) Notify a primary point
				of contact for the 9-1-1 authority within 15 minutes after a confirmed outage within
				the system and also advise the primary point of contact as to the magnitude of the
				outage. In addition, the telecommunications carrier must notify the Commission's 24
				hour emergency outage number (217-558-6166) pursuant to 83 Ill. Adm. Code
				730.550
				or
				737.430.
10) Shall notify a primary point of contact with
				the 9-1-1 authority and the Commission's 24 hour emergency outage number
				(217-558-6166) pursuant to 83 Ill. Adm. Code
				730.550
				or 737.734 within 30 minutes after the confirmed restoration of 9-1-1
				services.
11) Cooperate with 9-1-1
				system providers to assist in terminating split exchange traffic between 9-1-1
				systems.
12) Cooperate with 9-1-1 system
				providers in the installation of a new 9-1-1 system or migration of an existing
				9-1-1 system to another 9-1-1 system provider.
