Connecting adjunct power
The 400B2 adapter is convenient for connecting local -48 VDC power to a modular plug. See
Figure 77,
400B2 Adapter connecting to a modular plug,
on page 197.
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 media gateway. See
Auxiliary
connector outputs (MCC1 and Media Gateways only)
on page 203.
NOTE:
Adjunct power can be provided locally at the telephone or console by either the 1151B1 or
1151B2 power supply. Adjunct power can be provided from the equipment room or
equipment closet with the 1145B power unit. See
Installing and wiring telephone power
supplies
on page 228 for power supply information and installation procedures.
