3. Connection to DEFINITY ECS
All wiring between the DEFINITY ECS and the CALLMASTER VI voice
terminal including the line cord, must consist of twisted pairs.
Twisted-pair wiring makes lines less sensitive to crosstalk. The line
cord must be a D8W, which consists of four twisted pairs, or a Lucent
Technologies-approved equivalent.
Failure to use twisted-pair wiring may result in inadequate
performance of the terminal and also may contribute to line problems.

Distance Limitations

The distance that the CALLMASTER VI must be from the
DEFINITY ECS is determined by the diameter of the wire. See the
following specifications:
●Within 5,500 feet for 22-gauge wire
●Within 3,500 feet for 24-gauge wire
●Within 2,200 feet for 26-gauge wire.
WARNING: Failure to follow these instructions can cause damage to
the terminal or cause the associated DEFINITY ECS circuit pack to
remove power to the terminal. In either case, the terminal will not
function correctly.
