Keyphone Station Wiring
6.33. All stations are line run to common 66 type connecting blocks. Keyphones require 2-
pair twisted-pair industry standard cable. The maximum cable length is 350 m (1150
feet) with 0.65 mm (22 gauge) wire, 230 m (750 feet) with 0.5 mm (24 gauge) wire,
and 140 m (460 feet) with 0.4 mm wire (26 gauge). Single-line telephones can use a
cable length of up to 1600 m (5250 feet) using 0.65 mm (22 gauge) cable.
6.34. Each Keyphone is supplied with a four-wire, fully modular line cord. A 625 QA jack
assembly or equivalent should be mounted where each telephone will be installed.
Cable pairs should not be crossed or get reversed during installation. Polarity must
be maintained for correct operation of Keyphones.
