Follow these steps to install the housing.

A. Install Mounting Bracket

NOTE

The Repeater Housing is designed to be mounted

vertically, with the cable stub down.

(1) Clearances between the Repeater Housing

and adjacent structures must be observed for

access during maintenance. Refer to Figure

4 for the clearances required for removing

the housing cover and the tilting internal

case support.

(2) Verify that the proposed cable route does not

exceed the 40-foot stub cable length.

(3) The mounting bracket contains holes for

mounting the unit to a pole, in a vault, or in

a manhole. A guide for mounting bracket

holes is illustrated in Figure 5. Select the

location for mounting the unit and fasten the

mounting bracket appropriately.

B. Splice Wires

(1) Connect the wiring in the cable stub based

on the appropriate matching repeater

technology and housing wiring. Refer to

Table A for deployment restrictions, and to

Table B for circuit technology wiring

information.

NOTE

Some slot pairs inside the housing may not be

used, depending on the specific circuit

technology wiring.

(2) If installing an air-pressurized model (List 1)

and using remote pressurization, an air-tight

splice enclosure must be installed.

(3) Connect the ground cable to an appropriate

ground. Surge arrestors work only when the

ground cable is connected.
