The GCD-PRTA blade uses the first block of 24 consecutive trunks. For example, if
you have GCD-4COTB with GPZ-4COTF installed for trunks 1~8, the T1/PRI
Interface automatically uses trunks 9~32. If you have GCD-4COTB with GPZ-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 GCD-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.
A multiline terminal must be paired with a single line telephone. It cannot be paired
with another multiline terminal.
A single line telephone must be paired with another single line telephone. It cannot
be paired with a multiline telephone.
