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.
