1.4 Network Requirements and Testing

A. Telephone Common Carrier E 9-1-1 Network Requirements

1. Network Connectivity - Every wireless service provider shall provide 9-1-1 network connectivity to the RI E 9-1-1 selective router(s) free of charge to RI E 9-1-1.

2. Diversity and Redundancy - The 9-1-1 network is to be completely and fully diverse and consist of redundant routes (as further discussed hereunder) from the selective router(s) into the PSAP(s) and must follow all NENA recommended standards including, but not limited to, those standards relating to the trunking from the selective router(s) to the PSAP(s). The RI E 9-1-1 PSAP(s) must have two completely and fully diverse and redundant routes from the selective router(s) into the PSAP(s).

3. Trunking - E 9-1-1 wireline telephone service trunks shall be dedicated to handle only E 9-1-1 traffic. A minimum of two diverse and redundant routes shall be provisioned from each telephone common carrier’s central office(s), as follows: at a minimum one route from each central office to each of the two E 9-1-1 tandems, in Providence and in West Warwick, Rhode Island, respectively or any other tandems that may replace the Providence and West Warwick tandems. If the tandem locations are changed, the telephone common carriers will be afforded reasonable notice of the change so as to make the appropriate network modifications. RI E 9-1-1 may authorize the provisioning of an alternative trunking scheme upon a written request by both the Service Provider and a competitive local exchange carrier demonstrating that there are no facilities available within a reasonably foreseeable time and that the proposed alternative trunking scheme employs dedicated E 9-1-1 trunks, provides diversity and redundancy, and does not compromise the already existing network.

4. Grade of Service - Trunk quantities shall be based on a P.01 grade of service, e.g., so as to ensure that not more than one 9-1-1 call in 100 9-1-1 calls will experience a busy signal during the average busy season and time-consistent busy hour. As a general rule, the ratio of the number of central office trunks to the tandems should be as follows: up to 10,000 lines = two (2) trunks; 10,000 or more lines = an additional trunk for each additional 10,000 lines (or fraction thereof) over 10,000 lines.

5. Network Testing - Prior to commencement of service in Rhode Island, a telephone common carrier shall, conjunctively with RI E 9-1-1, conduct test calls. A minimum of two test calls shall be made from each NXX across each 9-1-1 trunk from the telephone common carrier’s central office to the E 9-1-1 tandems. Test calling shall be arranged with RI E 9-1-1 at least three business days in advance by notifying it. Testing will be scheduled after the telephone common carrier has made arrangements with the RI E 9-1-1 Database Manager. The telephone common carrier shall test the accuracy of the numbers to be tested and the municipalities within which they fall. The telephone common carrier shall input the telephone numbers to be tested into the ALI database at least 24 hours prior to the commencement of testing. Test calls shall be documented on a test log form prescribed by RI E 9-1-1, which shall include the following test measurements: validation of the display of the correct ANI; validation of the display of the correct ALI; call setup timing, including the interval between the time the last digit in 9-1-1 was pressed by the caller and an audible (ringing) signal was heard by the caller and the interval between the time the last digit in 9-1-1 was pressed by the caller and an audible (ringing) signal was heard at the PSAP; any other criteria as agreed upon by the telephone common carrier and RI E 9-1-1. Call testing results on the prescribed log form shall be sent to RI E 9-1-1 upon completion of testing, which shall provide a copy to the Database Provider for review and error correction.

6. Monitoring - Each telephone common carrier shall provide traffic studies for the average busy season and time-consistent average busy hour (as determined by RI E 9-1-1 call volume reports) every six months to ensure P.01 grade of service. RI E 9-1-1 and the telephone common carrier shall coordinate the every-six-month dates at which such studies will be conducted. RI E 9-1-1 shall have the right to perform line load studies periodically, but not more than every six (6) months and/or shall have the right to order each telephone common carrier to perform such line load studies, at its own expense, for purposes of ascertaining its subscriber base and/or conformance with technological standards, performance of service, and quality of service.

B. Wireless Carrier Network Requirements and Testing

1. Trunking - E 9-1-1 trunks shall be dedicated to handling only enhanced 9-1-1 traffic. A minimum of two diverse and redundant digital trunks shall be provisioned from each wireless carrier’s mobile telephone switch (MTS) as follows:

a. Primary Route - A minimum of one direct digital T1 carrier with a minimum of six channels (DSOs) utilizing Feature Group D signaling, or another industry standard authorized by RI E 9-1-1, shall connect the two (2) RI E 9-1-1 selective router(s). RI E 9-1-1, with the assistance of the Service Provider, shall provision the DSOs equally across the two digital trunks from the Providence DACS to the PSAP.

b. Default Route - A default route shall be provisioned over the public switched network of the Service Provider to the two tandems serving the E 9-1-1 network in Rhode Island. The wireless carrier shall use RI E 9-1-1-provided default number(s) as the default route in the event of failure within the 9-1-1 network.

c. Provisioning of MTS; Data Maintenance - Each wireless carrier shall send transmission tower location and cell sector information to RI E 9-1-1 in a format prescribed by RI E 9-1-1. The wireless carrier(s) shall request ESRK range in writing from the RI E 9-1-1 database manager. The RI E 9-1-1 database manager shall provide, as soon as reasonably practicable, the ESRK range to the wireless carrier. When a 9-1-1 call is sent over the Primary Route, a twenty (20) digit number shall be sent by the wireless carrier to the PSAP, consisting of the subscriber’s ANI (MIN) and the ESRK.

d. Grade of Service - Trunk (DSO) quantities shall be based on a P.01 grade of service or another grade of services as required by RI E 9-1-1.

e. Network Testing - Prior to commencement of service in Rhode Island, a wireless carrier shall, conjunctively with RI E 9-1-1, conduct test calls. Test calls shall be made using the primary route and the default route. Using the primary route, a minimum of two test calls shall be made from each cell sector for every tower. In addition, a minimum of two test calls shall be made across each DSO from the wireless carrier’s MTS. Using the default route, the wireless carrier shall “busy out” all digital circuits and thereby utilize the remote call forwarding arrangement. Test calls shall be documented on a test log form prescribed by RI E 9-1-1, which shall include the following test measurements: validation of the correct ANI (caller/subscriber’s mobile identification number, or MIN) display; validation of the correct ESRK display; validation of the correct ALI display concerning tower location; validation of the correct display of the cell tower and cell sector coverage on the PSAP map; call setup timing, including the interval between the time the last digit in 9-1-1 was pressed by the caller and an audible (ringing) signal was heard by the caller and the interval between the time the last digit in 9-1-1 was pressed by the caller and an audible (ringing) signal was heard at the PSAP; any other criteria as agreed upon by the telephone common carrier and RI E 9-1-1. Call testing results on the prescribed log form shall be sent to RI E 9-1-1 upon completion of testing.

f. Monitoring - Each wireless carrier shall provide traffic studies for the average busy season and time-consistent busy hour (as determined by RI E 9-1-1 call volume reports) every six months to ensure P.01 grade of service. RI E 9-1-1 and the wireless carrier shall coordinate the every-six-month dates at which such studies will be conducted. RI E 9-1-1 shall have the right to perform cell site channel loading studies periodically, upon the giving of fifteen days’ calendar notice, but not more than every six (6) months, and/or shall have the right to order each wireless carrier to perform such cell site channel loading studies, for purposes of ascertaining its subscriber base and/or conformance with technological standards, performance of service, and quality of service.

1.5 Local Number Portability

A. Purpose of Local Number Portability

1. Local Number Portability (LNP) was authorized under the federal Telecommunications Act of 1996 to facilitate competition in local telephone service markets by permitting a customer of one telecommunication services provider to switch to another telecommunication services provider while retaining the same telephone number. This “portability” feature has public safety implications for RI E 9-1-1, and is the reason for Rules and Regulations concerning it.

B. Procedures for Migration of Telephone Numbers

1. The Recipient Company shall be solely responsible to obtain authorization from the end user for the migration of the end user’s telephone number from the Donor Company. In addition, the Recipient Company shall provide verification to the Database Provider that the end user’s telephone number has been ported (migrated) to the Recipient Company by the Donor Company. The procedures for the migration of the number from the Donor Company to the Recipient Company and to the Database Provider shall, in all other respects, be those set forth in “NENA Recommended Standards for Local Exchange Carriers, ALI Service Providers, and 9-1-1 Jurisdictions” of the National Emergency Number Association (NENA), as revised from time to time.

C. Prohibited Action by Donor Company

1. A Donor Company is prohibited from thwarting, delaying, prohibiting, or otherwise impeding the migration of a telephone number due to any unpaid charges, prior service disputes, or billing disputes with the end user.

1.6 Cost Recovery

A. Cost Recovery

1. In the case of telephone common carriers providing service in Rhode Island, the cost of providing 9-1-1 services is governed by R.I. Gen. Laws § 39-21-12. In the case of wireless telephone carriers, 9-1-1 service is regulated by the Federal Communications Commission pursuant to statutes of the United States of America, with the costs of such service recoverable in accordance with state and federal laws and rules and regulations. In accordance with the FCC determination in re: King County (Washington), CC Docket Number 94-102, and in the absence of an agreement to the contrary, wireless telephone carriers operating within Rhode Island are required to provide 9-1-1 services up to the input of the RI E 9-1-1 selective router(s) at no charge to RI E 9-1-1.
