(a) Each service provider shall provide access from its exchanges at all hours to local assistance operators who shall be capable of connecting calls to appropriate emergency services and/or other operator services normally provided by local exchange companies or their designees, if the service provider is responsible for handling the call.

(b) All telephone corporations, either individually or in concert with other telephone corporations operating within the State, shall be responsible for insuring the provision of a relay system to enable communications between persons with hearing or speech disabilities, who use non-voice terminal devices, and persons of normal hearing and or speech who use conventional telephones. The system shall operate on a 24-hour basis. All telephone corporations shall provide annual notice to advise customers of this service. Pertinent information regarding the relay system shall be included in telephone directories.

(c) All service providers shall provide network overflow to local operators on all originating trunking that carries emergency calls destined for enhanced 911 emergency report centers. Each such call overflowing to the operator shall be identified as an emergency call, and the operator shall have automatic number identification on the telephone line used by the calling party. As an alternative to provision of overflow to the operator on an originating basis, service providers may install originating trunking from end offices to enhanced 911 emergency report centers in such a manner that blocking on such trunks is engineered for less than half the normal blocking design of the public switched network. On a terminating basis from the last central office to the emergency report center, overflow to the operator (including automatic number identification and an indication that the call was originally destined for an emergency center) shall always be provided.
