Enhanced Emergency Number Service, also referred to as E9-1-1, is a telephone communication service whereby one or more Public Safety Answering Points (PSAP) designated by the local authority may receive telephone calls dialed to the telephone number Traditional E9-1-1 Service has typically included lines and equipment within one telephone company exchange and/or area served by a Mobile Telephone Switching Office, which could be connected to lines and equipment in another telephone company exchange to permit answering, transferring and dispatching of public emergency telephone calls originated by persons within the same serving area. However, E9-1-1 Service may become more decentralized insofar that no single company may provide all of the E9-1-1 hardware, software, or features. The use of twisted pair telephone lines is becoming obsolete, replaced by broadband IP connectivity via cable or DSL or other dedicated IP networks. The Company anticipates that different companies shall provide the IP E9-1-1 infrastructure, while other companies provide the E9-1-1 content, features, and functions. This tariff identifies the rules, regulations, and prices that shall govern the Company s offering of the E9-1-1 features and functions. b. Enhanced Service is offered subject to availability of IP broadband facilities. c. The E9-1-1 customer may be: (1) A municipality or other state or local governmental unit, or an authorized agent of one or more municipalities or other state or local governmental units to whom authority has been lawfully delegated.

16 Competitive Local Exchange Carrier Original Page 15 SECTION 3. SERVICE OFFERINGS AND FEATURES, CONTINUED e. E9-1-1 Service is provided solely for the benefit of the customer operating the PSAP, or for the carrier providing telecommunications or data communications service to individuals. The provision of the E9-1-1 Service by the Company shall not be interpreted, construed, or regarded, either expressly or implied, as being for the benefit of or creating any Company obligation toward any third person or legal entity other than the customer(s). The Company does undertake to provide E9-1-1 services using facilities obtained by the PSAP to enable the PSAPs personnel to respond to emergency calls on the PSAPs premises. The PSAP is responsible for the provision and maintenance of cable and wire facilities on the PSAPs side of the Demarcation Point. f.

Toll Presubscription is a procedure whereby a customer designates to the Company the IntraLATA and InterLATA Toll Providers, i.e., Interexchange Carriers (IXCs), which the Customer wishes to be the carriers of choice for toll calls. Such calls are automatically directed to the designated carrier(s) without the need to use carrier access codes or additional dialing to direct the calls to the designated carrier. Toll presubscription does not prevent a customer, who has presubscribed to a toll carrier, from using carrier access codes or additional dialing to direct calls to an alternative toll carrier on a per call basis. Each carrier will have one or more access codes assigned to it for various types of service. When an end user selects a carrier as its preferred IXC, only one access code of that carrier may be incorporated into the switching system of the Company permitting access to that carrier by the end user without dialing an access code. Should the same end user wish to use other services of the same carrier, it will be necessary for the end user to dial the necessary access code(s) to reach that carrier s other service(s). An IXC must use Feature Group D (FGD) Switched Access Service to qualify as a presubscription toll provider unless prior arrangements have been made with or by the Telephone Company. IXCs must submit an Access Service Request (ASR) to the Telephone Company. Selection of toll presubscription provider by an end user is subject to the terms and conditions following. 2. At the option of the IXCs, the nonrecurring charge for a change in toll presubscription, as provided herein, may be billed to the IXCs, instead of the end user (NRC PIC). This may involve charges resulting from end-user initial free choice Preferred Interexchange Carrier (PIC), specified as follows. 3. Presubscription Charge Application a. End user choices for toll presubscription: (1) Designating an intralata and interlata IXC(s) as primary carrier(s) thereby requiring no access code to access those IXCs service. End users are not required to choose the same IXC for intralata and interlata toll presubscription. Other nonpresubscribed IXCs are accessed by dialing 10XXX, 101XXXX, or other required codes.

22 Competitive Local Exchange Carrier Original Page 21 SECTION 3. SERVICE OFFERINGS AND FEATURES, CONTINUED (2) Choosing no carrier as a primary carrier thus requiring 10XXX or 101XXXX code dialing to access all IXCs. b. If a new customer cannot decide upon presubscription IXCs, the Company may extend a 30 calendar day period following completion of the initial service request to make a choice without charge. In the interim, the customer will be assigned as a No-PIC and must dial an access code to make toll calls. 4. If an IXC elects to discontinue Feature Group, the IXC is obligated to contact, in writing, all end users who have selected the canceling IXC as their preferred toll provider. The IXC must inform the end users that it is canceling its Feature Group D Service, request that the end user select a new IXC, and state that the canceling IXC will pay the PIC change charge as provided herein (PIC Change). The IXC must provide written notification to the Telephone Company that this activity has taken place. Following the IXC s discontinuance of service, the Company will bill the canceling IXC the change charge for each end user that is currently designated to the IXC at the time of discontinuance (PIC Change). 5. An unauthorized PIC change is a change in the presubscribed IXC that the end user denies authorizing. PIC disputes for end users are resolved through an investigative process. If an unauthorized change in toll presubscription occurs, the IXC making the unauthorized change will be assessed a charge for unauthorized change in presubscription as provided at the end of this section (PIC Change). In addition, the IXC will be assessed the applicable charge for returning the end user to the preferred IXC (PIC Change). H. End User Charge Discrepancy 1. When a discrepancy is determined regarding an end user s designation of a presubscription IXC, the following applies depending upon the situation described: a. A signed letter of authorization takes precedence over any order other than subsequent, direct customer contact with the Company. b. When two or more orders are received for an end user line generated by telemarketing, the date field on the mechanized record used to transmit PIC change information will be used as the PIC authorization date. The order with the latest application date/time determines customer choice. c. If an end user denies requesting a change in toll presubscription as submitted by an IXC, and the IXC is unable to produce a letter of authorization, signed by the end user, the IXC will be assessed all applicable change charges. The nonrecurring change charges are provided herein. The IXC will also be assessed the presubscription change charge as specified herein, which was previously billed to the end user (PIC Change).

23 Competitive Local Exchange Carrier Original Page 22 SECTION 3. SERVICE OFFERINGS AND FEATURES, CONTINUED 2. Verification of Orders for Telemarketing Neither the IXC or the Company shall submit a PIC change order generated by outbound telemarketing unless and until the order has first been confirmed in accordance with the F.C.C. s current antislamming practices and procedures. I. PIC Switchback Option-Business/Residence 1. PIC Switchback is an option under which no investigation activities are performed by the Company when an end user denies requesting a change in primary toll carrier submitted by the IXCs. The IXC participating in PIC Switchback will be billed the PIC Switchback Charge, and the presubscription change charge, as specified herein, to switch the end user to the end user s previous carrier (PIC Switchback). 2. When the Company is contacted by an end user who denies requesting a change in primary toll carrier, the end user will be credited the charge assessed for the disputed change in carrier, and will be switched back to the previous IXC at no charge. If this service is made available by the Company, IXCs may subscribe to or cancel PIC Switchback Service on 30 calendar days notice to the Company by submitting a written request. A letter of authorization from the IXC will not be requested or accepted at a later date in the event of dispute of the charges assessed under the PIC Switchback option. 3. This option in no way relieves an IXC of the F.C.C. requirements for verifying all PIC orders obtained by outbound telemarketing prior to submitting those orders, or instituting steps to obtain verification of orders submitted to the Company. 4. In addition, the end user has the option of initiating a complaint to the F.C.C. or the Pennsylvania Public Utility Commission s Bureau of Consumer Services concerning unauthorized changes in toll presubscription. J Service For End User Customers 1. The Service Access Code allows the customer to reach the appropriate emergency services including police, fire and medical services. Enhanced has the ability to selectively route an emergency call to the primary provider so that it reaches the correct emergency service located closest to the caller. In addition, the Customer s address and telephone information will be displayed to the primary provider for display at the Public Answering Point (PSAP).

K. Pennsylvania Telephone Relay Service 1. General The Pennsylvania Telecommunications Relay Service (PA TRS) is a relay telecommunication service for the deaf, hard of hearing, hearing and/or speech disabled population of the Commonwealth. The PA TRS is mandated by the Americans with Disabilities Act of 1990 to provide functionally equivalent telephone services that are available to other U.S. citizens, at no additional cost. The PA TRS includes both traditional relay (devices such as Teletypewriters (TTY) and Telecommunication Devices for the Deaf (TDD)) and captioned- telephone voice-carry-over relay services (captioned telephone). These relay services permit telephone communications between individuals with hearing and/or speech disabilities, who must use a TTY, TDD, or captioned telephone, with individuals having normal hearing and speech. Additionally, 711 abbreviated dialing is available to access the PA TRS. The Company s switching equipment is arranged to translate the 711 calls to the assigned toll- free number, (888) , in order to route calls to the Telecommunications Relay Service Provider, in accordance with Commission s Order entered on February 4, 2000 at Docket No. M Surcharge In addition to the charges provided in this tariff, a surcharge will apply to all residence and business access lines served by this Company (Access lines are those lines extending from the telephone company s central office to the end-user s premises).
