Installing and wiring telephone power supplies
This section provides information and wiring examples of installation procedures for various
telephone and console power supplies. These are examples only and actual wiring procedures
may vary at each site.
The power is provided to telephones or consoles either centrally or locally.
Centrally located power supplies include:
●
1152A1 mid-span power distribution units on page 324
Local power supplies include:
●
1151B1/C1 and 1151B2/C2 power supplies on page 333
Typical adjunct power connections
The 400B2 adapter is convenient for connecting local -48 VDC power to a modular plug. See
Figure 24: 400B2 Adapter Connecting to a Modular Plug on page 322.
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 1151B1/C1 or
1151B2/C2 power supply. The 1151A1 is a standard (no battery backup) power supply unit. The
1151B2/C2 is a battery backup version of the 1151B2/C2. 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.
