Typical Adjunct Power Connections
The 400B2 adapter is convenient for connecting local -48 VDC power to a modular plug. See “400B2
Adapter Connecting to a Modular Plug” on page 256.
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 G700 Media Gateway.
Adjunct power can be provided locally at the telephone or console by either the 1151A1 or 1151A2 power
supply. The 1151A1 is a standard (no battery backup) power supply unit. The 1151A2 is a battery backup
version of the 1151A1. Either power supply can support one telephone with or without an adjunct. The
maximum loop range is 250 feet (76 meters). Two modular jacks are used. Power is provided on the
PHONE jack, pins 7 and 8 (- and +, respectively).Adjunct power can be provided from the equipment room
or equipment closet with the 1145B power unit.
