T1 Trunking (with ANI/DNIS Compatibility)
Description
The T1/PRI Interface PCB gives the system T1 trunking capability. This PCB uses a single univer-
sal slot and provides up to 24 trunk circuits. In additional to providing digital-quality trunking, the
T1/PRI Interface PCB allows you to have maximum trunking capability with fewer PCBs. This in
turn makes more universal slots available for other functions.
You can program each T1/PRI PCB for any combination of the following trunks:
● CO loop start
● CO ground start
● Direct Inward Dialing
● Tie lines
1
The T1/PRI Interface PCB uses the Þ rst block of 24 consecutive trunks. For example, if you have
an 8COIU PCB installed for trunks 1-8, the T1/PRI Interface PCB will automatically use trunks 9-
32. If you have 8COIU PCBs installed for trunks 1-8 and 17-24, the T1/PRI PCB will use 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 PCB requires that 24 consecutive ports be available in
the system even if not all the ports will be used otherwise the PCB will not function.
