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.
