Connecting the Control Unit to the
4
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 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
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 telecommunications wiring. For example, you cannot use indoor
wiring (DIW) cable 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.
