Power and cabling are consistent with current DEFINITY ECS wiring. See the
DEFINITY ECS Installation and Test document for specific information describing
typical adjunct powering configurations.
Inside Wiring Cable
The Category 3 or greater inside wiring cable connecting the RC with the WFB is
wired identically to the DEFINITY ECS digital telephones. (Refer to the “RC Circuit
Pack TN789 Pin Configuration” table earlier in this chapter.) This interface follows
standard 2-pair distribution practices and is typically wired from the distribution
closet with Category 3 4-pair twisted cable. Cable pairs 2 and 3 are used for
receive and transmit, respectively. Pair 4 is used for auxiliary power. The following
figure provides representative building wiring. See the DEFINITY ECS Installation
and Test document for additional information.
