Initial Installation of Trunk PCBs

When first installing the system:
1. Insert all PCBs in sequential order. The installer must install trunk PCBs in order (i.e.; slot 5 first, slot 6
next, slot 7 next, etc.) for a sequential numbering plan.
Installing COIU, 4TLIU, DIOPU, or BRI PCB's:
The order in which trunk PCBs are physically inserted determines the numbering plan.
For example, if four PCBs are installed in the following order, the numbering plan below
would apply:
Installing T1/PRI PCBs
The T1/PRI Interface PCB uses the first block of 24 consecutive trunks.
For example, if you have an 4COIU PCB with a 4COIDB installed for trunks 1-8, the T1/
PRI PCB will automatically use trunks 9-32. If you have 4COIU PCB with a 4COIDB
installed for trunks 1-8 and 17-24, the T1/PRI PCB will use trunks 25-48. The T1/PRI
PCB cannot use trunks 9-16 (even if available) since they are not part of a consecutive
block of 24 trunks.

Initial Programming (Figure 2-43)

The system can be programmed using three methods:
●
Programming through a digital or IP keyset
●
PC Programming
●
Web Programming
Refer to the UX5000 Software Manual (P/N 091200) for complete details on programming.
