Power supply board
The power supply option consists of a power supply board that mounts inside
the telephone, coupled with an external wall-mount transformer or closet
power supply that provides power to the power supply board. The power
supply board receives its power through pins 1 and 6 of the line cord.
The power supply board connects to the telephone through a 14-pin bottom
entry connector.
Local plug-in transformer
A single winding transformer equipped with a 10 ft. (3 m) cord of 22 AWG
two-conductor stranded and twisted wire with a modular RJ-11 duplex
adapter can provide the additional power needed to operate the telephone and
its options. See "Configuration of local plug-in transformer" on page 303.
Do not plug any equipment other than the terminal into the RJ-11
transformer adapter, as damage to equipment can result.
