necessary, auxiliary power must be connected to pair 4.

pair 1 and, if necessary,
auxiliary power must be connected to pair 4.
Wiring Note for the CALLMASTER VI
All wiring between the DEFINITY ECS and the CALLMASTER VI, 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.

located from the DEFINITY G1, G2, and G3, DEFINITY ECS, System 75, or
System 85 cabinet is shown in the table below.

directly above. However, the CALLMASTER II and CALLMASTER III are
only supported when connected to a DEFINITY G3. The CALLMASTER IV
is supported only when connected to a DEFINITY G3V3.

(1219 m) for 26 AWG wire with the use of a Data Link Protector. Refer to EXPOSED
