T1 Trunking (with ANI/DNIS Compatibility)
Description
The T1/PRI Interface gives the system T1 trunking ability. This unit provides up to 24 trunk circuits. In additional to providing digital-quality trunking, the T1/PRI Interface allows you to have maximum trunking ability with fewer unit. This in turn makes more universal slots available for other functions.
You can program each T1/PRI for any combination of the following trunks:
•CO loop start
•CO ground start
•Direct Inward Dialing
T T1/PRI uses the first block of 24 consecutive trunks. For example, if you have a COIU installed for
trunks 1~8, the T1/PRI Interface automatically uses trunks 9~32. If you have COIU installed for trunks 1~8 and 17~24, the T1/PRI uses trunks 25~48. The T1/PRI Interface cannot use trunks 9~16 (even if available) since they are not part of a consecutive block of 24 trunks. Each T1/PRI requires that 24 consecutive ports be available in the system even if not all the ports are used otherwise the unit does not function.
The T1/PRI can be programmed as a 4/8/12/16/20/24 port Fractional T1/PRI. ANI/DNIS Compatibility
The system is compatible with Telco T1 Automatic Number Identification (ANI) and Dialed Number Information Service (DNIS) services. A compliment to Caller ID service, ANI/DNIS Compatibility provides:
•Receive Format
The Receive Format must be set as *ANI*DNIS* in PRG 34-09-01 option 4, which is treated as a Feature Group D format. (Example of ANI Information KP009727517645STKP7100ST.)
•Flexible Routing
Based on the data received, the system can route the incoming ANI/DNIS call to:
-An extension
-An ACD or Voice Mail master extension number (V1.5 or higher)
-A VRS and play a VRS message to the caller
-A Department Group pilot number
-A trunk Ring Group
•Route According to DID Translation Table or Speed Dial Bins
Calls can be routed based on either the number of digits defined in PRG 22-09-01 (digits 1~8) or by digits entered in Speed Dial bins in PRG 13-04-01.

•Data Error and Unanswered Call Handling
If a call cannot be completed, send it to a predetermined Ring Group or play supervisory tones to the caller.
Conditions
•At Release 1 Receive Format for ANI/DNIS is Feature Group D (PRG 24-09-01, option 4) only. Other Formats are future enhancement.
•T1 Trunking requires a T1/PRI Interface and a customer-provided CSU/DSU to interface with the Telco. Consult your sales representative and the System Hardware Manual for additional details.
•ANI/DNIS Compatibility requires using system DTMF receivers. When all receivers are busy, the incoming ANI/DNIS call waits for a receiver to become available
