When installing Caller ID on a 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 will get Caller ID service only on the first four PCB trunk circuits.
