Connecting adjunct power

The 400B2 adapter is convenient for connecting local -48 VDC power to a modular plug. See Figure 35: 400B2 Adapter connecting to a modular plug on page 75.

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 SCC1 Media Gateways only) on page 81.

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 109 for power supply information and installation procedures.
