POWER FAILURE TELEPHONES
Power Failure Cut-Through(Figure 4-5)
When system AC power fails, the 8ATRU PCB automatically
cuts through the first 2 trunk circuits to 2 Power Failure
Telephone connections.To install Power Failure Cut-Through:
1. Locate an available 8-pin jack in a trunk (A) block or station
(B) block.
Local codes may prevent you from using a DDK con-
nector on the A block for optional equipment.
2. For the 8-pin jack chosen, cross-connect the associated wire
pair from the A or B block...

2-OPX MODULE
Installing the 2-OPX Module (Figure 4-8)
The 2-OPX Module (P/N 92177A) provides two 2500 type ana-
log circuits for connection to on-premise 2500 type single line
devices (i.e., telephones, fax machines, modems, etc.) and to
telco OL13B/C OPX circuits. It uses a single digital extension
circuit for the power and signaling for both analog ports.To install a 2-OPX Module:
1. Locate an 8-pin modular connector in a trunk block or sta-
tion block.
Local codes may prevent you from using a...
