Connecting The Control Unit To The Network Interface - AT&T MERLIN LEGEND Release 3.0 Installation Manual

Connecting the Control Unit to
the Network Interface
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 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.
If the network interface is greater than 25 ft. (7.62 m) from the control
unit, connect the control unit to the network interface, using an Off-
Premises Range Extender (OPRE). See the documentation packaged
with the OPRE for complete installation instructions.
If you use staples to attach the cords to walls or baseboards, make sure
you do not pierce the cords.
National and local building codes specify the type of cable required for
telecommunication wiring. For example, you cannot use indoor wiring
(DIW) cab/e inside or on top of air plenums or ducts, along hot pipes, or
across walkways. Consult your local ordinances and regulations for
proper cable selection.
