Wireless Fixed Base

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.
