Network Interface 4
NOTE:
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.
