Comtest Networks Inc.

This guide provides the basic information required to install the Comtest Model 3144 POTS/ISDN Splitter Shelf

in a Central Office location.

Installation

The 3144 requires 3U (5.25 inches) of rack space. The

allow installation in a 19 inch or 23 inch rack. By

repositioning the mounting brackets, the shelf can be

installed with the connectors front or rear facing. With the

connectors facing the front, a depth of 10 inches would be

sufficient to mount the shelf with cables installed.

(NEBS) requirements, a suitable ground must be provided.

The 3144 is to be grounded to the rack, with the use of a

separate a ground wire, through the ground point at the rear

of the shelf.

The 3144 Splitter Shelf cabling configurations will vary depending on installation locations

and the number of lines supported by the DSLAM. However, the physical interface to the

Front Panel connectors are standard 50-pin RJ-21 type receptacle connectors. Each

Splitter card uses 24 pairs of the 25 pairs available on each 50-pin connector.
