Refer to page 4-18 when connecting a DEFINITY ECS or DEFINITY ProLogix to a MERLIN LEGEND Communications System or a MERLIN LEGEND Communications System to another MERLIN LEGEND Communications System in the same building for correct wiring at the cross connect field.

The way you connect the control unit to the network interface depends on the type of network interface that is installed. While there are many ways you can do this, the methods discussed in this chapter are usually best.

! CAUTION:

The local telephone company is responsible for providing appropriate protection for central office trunks. Do not connect the central office trunks until you are certain that they are properly protected. See “Central Office Trunk Protection” in Chapter 2 for details.

To avoid coupling power supply noise onto system wiring, allow at least 3 in. (7.62 cm) of clearance between the basic carrier’s power supply and any wiring or termination hardware located to the left of the control unit.
