PACU - AC15 Tie Line Unit

Interfaces with:
Older Version(s):
Each PACU Interface Unit decreases the maximum number of system exchange lines by four.
Each PACU Interface Unit will support four AC15 'type A' tie lines. If the system is connected to
another Strata system (or any system in compliance with BTNR181, section 4) the recall feature
inherent in AC15 'type C' signalling which allows anti-tromboning will be available.
Note For the system to recognise the DTMF tones generated by incoming TIE lines a DTMF
receiver unit (BRCS) must be installed on the Strata CT Processor PCB.
PACU controls, indicators and interface connectors are shown in
Table 4-13.

PACU Installation

1. Insert the PACU (component side facing right) into the appropriate Expansion cabinet slot and
apply firm, even pressure to ensure proper mating of the connectors.
Each PACU decreases the maximum system exchange lines by four.
Important!
After installing, gently pull the PACU outward. If the connectors are properly mated, a slight
resistance is felt.
