Order of Installing Extension PCBs
The order that the station PCBs (e.g. ESIU and SLIU) are physically inserted determines the
numbering plan.
For example, with a digital station card (16ESIU) in slot #1 (ext. 301-316), when 3 additional digital
station cards are installed in the following order, the numbering plan below applies:
After the initial powering up of the system, subsequent powering up or resets will not change the slot
identification. System programming (Program 90-05) must be performed to change the slot identifica-
tion.

The PRI Interface PCB uses the first block of 32 consecutive trunks.
For example, if you have an 8COIU PCB installed for trunks 1-8, the PRI PCB will automati-
cally use trunks 9-40. If you have 8COIU PCBs installed for trunks 1-8 and 17-24, the PRI
PCB will use trunks 25-56. The PRI PCB cannot use trunks 9-16 (even if available) since they
are not part of a consecutive block of 32 trunks.
