❏ Install the Caller ID daughter boards as required for your site.
For Caller ID capability, install Caller ID PCB daughter boards on the
ATRU PCBs. The 4ATRU uses the 4 circuit Caller ID daughter board,
P/N 92012; the 8ATRU uses the 8 circuit daughter board, P/N 80013. The
Caller ID PCB provides Caller ID capability for all trunk circuits on the
ATRU PCB. Every ATRU PCB in the system can have a Caller ID daugh-
ter board.
If you are installing Caller ID on an ATRU PCB in the last slot, you
may have to adjust your system’s ground wire connection so it
won’t obstruct the daughter board.
If you install a P/N 92012 Caller ID PCB on an 8ATRU PCB (P/N
80011A), you’ll get Caller ID service only on the first four PCB
trunk circuits.
1. Remove the headers from the ATRU PCB connectors (CN3 on P/N
92012, CN3 and CN4 on P/N 80013) and store them in a safe place (see
figure above).
2. Align the Caller ID PCB standoffs over the holes located in the ATRU
PCB.
On the 8ATRU PCB, note that the CN2 connector on the Caller ID
PCB should be above the CN3 connector on the 8ATRU PCB. CN3
on the Caller ID PCB should be above CN4 on the 8ATRU PCB.
CN1 on the Caller ID PCB should be above CN2.
On the 4ATRU PCB, note that the CN2 connector on the Caller ID
PCB should be above the CN3 connector on the 4ATRU PCB. CN1
on the Caller ID PCB should be above CN2 on the 4ATRU PCB.
3. Push the PCB down until the standoffs snap into place.
