directly, or into a 2-slot or 5-slot carrier.

Avaya urges: “The power cord should hang straight down from the

Partner system phones require two pairs of wire. Ordinary 6-pin modular
telephone jacks work well, using pairs 1 and 2 (the center 4 pins.)
Partner system phones use 8-pin modular jacks, using pairs 1 and 2 (the
center 4 pins.) CAT-5 style cables work well with Partner phones, and
provide enhanced immunity to radio frequency interference.
The first pair (White/Blue, Blue/White) in station wiring is fully tip-ring
compatible; a system phone and a standard single-line phone can be bridged
on this pair. The second pair (White/Orange, Orange/White) provides power
and signaling information to Partner system phones.

is believed to be accurate, though not necessarily identical to the
internals of an Avaya 355A adapter.
