T1 Trunking (with ANI/DNIS Compatibility)
The T1/PRI Interface gives the system T1 trunking ability. This blade uses a single
universal slot and 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 blades. This in turn makes more universal slots available for other
functions.
You can program each T1/PRI for any combination of the following trunks:




The CD-PRTA blade uses the first block of 24 consecutive trunks. For example, if you
have CD-4COTB with PZ-4COTF installed for trunks 1~8, the T1/PRI Interface
automatically uses trunks 9~32. If you have CD-4COTB with PZ-4COTF 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 blade does not function.
The CD-PRTA can be programmed as a 4/8/12/16/20/24 port Fractional T1PRI.
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:

Tandem Ringing
Tandem Ringing allows an extension user to have two telephones with one telephone
number. For example, extension 105 (the master telephone) sets Tandem Ringing
with extension 106. When extension 105 receives an incoming call, both extensions
105 and 106 ring. Callers dial the master extension number (extension 105 in this
example). When either the master telephone or slave telephone is in use, the other
telephone cannot be used for outgoing calls or incoming calls.
