Analog Trunk (8ATRU and 4ATRU) PCBs
(Figures 2-10 and 2-11)
The 8ATRU provides connection for 8
loop start analog trunks. The 4ATRU
PCB connects 4 loop start analog trunks.
Refer to Section 3, Installing Extensions
and Trunksfor wiring instructions.
To install ATRU PCBs:
1. Install ATRU PCBs as required.
In U Slot systems, see System
Configuration in Section 1.
In Fixed Slot systems, plug the
8ATRU PCB for trunks 1-8 into slot
CN3. Plug the 8ATRU PCB for

8 Circuit Caller ID Daughter Board (Figure 2-12)
For Caller ID capability, install 8 circuit Caller ID PCB daugh-
ter boards (P/N 80013) on the 8ATRU PCBs (P/N 80011A
).
The Caller ID PCB provides Caller ID capability for all eight
trunk circuits on the 8ATRU PCB.  Every 8ATRU PCB in the
system can have a Caller ID daughter board.
If you are installing Caller ID on an 8ATRU PCB in the
last slot, you may have to adjust your system’s ground
wire connection so it won’t obstruct the...

CONNECTING BLOCKS
Working With 8-Pin Jacks
The system uses 8-pin mod jacks to connect extensions, trunks
and optional equipment. Using the Installation Cable (P/N
80892) makes it easy to connect the PCBs to standard 66M1-50
connecting blocks. These cables have 6 8-pin modular jacks on
one end and are unterminated on the other. In general, each cab-
inet needs:

One 66M1-50 block and Installation Cable (P/N 80892) for
extensions and optional equipment.


One 66M1-50 block and Installation Cable (P/N...
