Title 17 - TREASURY - GENERAL
Chapter 24 - 9-1-1 EMERGENCY TELEPHONE SYSTEM
Subchapter 4 - NETWORK FEATURES AND DESIGN
Section 17:24-4.1 - Network features

1. Selective routing: A feature that routes a 9-1-1 call from a central office to the designated PSAP based upon the identified number of the calling party or, in the case of a wireless call, a unique 10-digit identification number for each cell site, or if so configured, each sector at the cell site;

2. Automatic number identification (ANI): The automatic display of the 10-digit number used to place a 9-1-1 call;

3. Automatic location identification (ALI): The automatic display of information on a computer-like screen which displays the geographical location of the telephone used to place a 9-1-1 call;

4. Idle-circuit-tone application: An idle circuit tone which enables the PSAP attendant to distinguish between calls that have been abandoned before they are answered and calls where the calling party is connected but unable to speak;

5. Switchhook status indication: A feature which provides the PSAP with visual indications of whether a 9-1-1 call which has been received and put on hold is still on hold or has disconnected. This feature helps ensure that a caller's line is not held up unnecessarily after the emergency call is completed;

6. Forced disconnect: A feature which enables the PSAP to release a connection (hang up to clear the line) on a 9-1-1 call even if the calling party has not hung up. The time required for a forced disconnect varies with telephone central office switching equipment, but is generally under 10 seconds. This feature prevents intentional jamming of 9-1-1 lines by individuals who dial 9-1-1 and refuse to hang up;

7. Alternate routing: A feature which provides backup for a PSAP by routing 9-1-1 calls to an alternate PSAP when all lines to the intended PSAP are busy, out of service, or have exceeded the pre-determined queue length;

8. Default routing: A feature which provides backup for a PSAP by routing 9-1-1 calls to a location based on the originating local trunk group when an incoming 9-1-1 call cannot be selectively routed due to an ANI failure, garbled digits, party-line service or multi-party service, or for any other reason;

9. Selective transfer: A feature which allows call-takers to transfer incoming calls to PSDPs by depressing a single "type of service" button;

10. Call detail recording: A record for each 9-1-1 call indicating the caller's telephone number, the time the 9-1-1 telephone equipment seized the line, the time the call was answered, the time the call was transferred (if appropriate), the time the call was disconnected, the trunk line the call came in on, and the call-taker position in the PSAP stored either on electronic or printed media;

11. Protected circuits: All facilities and equipment associated with, included in or attached to the 9-1-1 network shall be equipped with protective devices to prevent accidental worker contact. Each protected termination shall be clearly identified, and no protected 9-1-1 circuits shall be opened, grounded, short-circuited, or manipulated in any way unless the appropriate PSAP has released the circuit;

12. Calling party hold: (Reserved); and

13. Ringback: (Reserved).
