Install cross-connect jumpers to wire the terminal to the port circuit pack. See Figure 192, 302C1
to 4-wire DCP Wiring, on page 503. This pinout is for the 4-wire Digital Line circuit pack.
CAUTION:
Do not use the 329A power unit for the attendant console. Use an 1151A1, 1151A2,
1145A, or MSP-1 power unit.

The 400B2 adapter is convenient for connecting local -48 VDC power to a modular plug. See Figure 193,
400B2 Adapter Connecting to a Modular Plug, on page 504.
Each port network can provide power for up to three attendant consoles. This source of power is preferred
for the attendant consoles because it has the same battery backup as the system. See
Auxiliary Connector
Outputs on page 510.
NOTE:
Adjunct power can be provided locally at the telephone or console by either the 1151A1
or 1151A2 power supply. Adjunct power can be provided from the equipment room or
equipment closet with the 1145B power unit. Go to
Install and Wire Telephone Power
Supply on page 549 for power supply information and installation procedures.
