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 318.
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) powe r 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.
