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
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
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.
ANI/DNIS Data Displayed as Caller ID Data
• 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.
