PACU
AC15 Tie Line Unit
System:
DK40 Expansion KSU
Circuits per PCB:
four AC15 tie lines
Interfaces with:
AC15 ‘type A’ circuits
Compatible Slot(s):
slots 15 ~ 18
Older Version(s):
PACU1 (not compatible with DK40)
Each PACU Interface Unit decreases the maximum number of system exchange lines by four
(See Chapter 1 – DK40 Configuration).
Each PACU Interface Unit will support four AC15 ‘type A’ tie lines. If the system is
connected to another Strata DK 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 (K5RCU) must be installed on the DK40 Base KSU.
The Strata DK40 assigns one station port number to each Tie line connected. These station
port numbers are only available in order to program certain attributes to the Tie lines
connected to the PACU, PEMU PCBs, (i.e. Toll Restriction and Least Cost Routing). The
station port numbers assigned to each PACU PCB/Tie line circuit are shown in Table 3-6.
Table 3-6 Tie Line Station Numbering Assignments
PACU controls, indicators and interface connectors are shown in Figure 3-9 and described in
Table 3-7.
PACU Installation
1. Insert the PACU (component side facing right) into the appropriate Expansion KSU
cabinet slot and apply firm, even pressure to ensure proper mating of the connectors.
Important!
Each PACU decreases the maximum system exchange lines by four.
2. After installing, gently pull the PACU outward. If the connectors are properly mated, a
slight resistance is felt.
