This guide provides the basic information required to install the Comtest Model 2144 POTS/ISDN Splitter Shelf in a Central Office location.

Installation

The 2144 requires 3U (5.25 inches) of rack space and is centre mounted. The shelf is supplied with mounting brackets and hardware to 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 rear, a depth of 10 inches would be sufficient to mount the shelf with cables installed.

Grounding

To comply with the Network Equipment Building Systems (NEBS) requirements, a suitable ground must be provided. The 2144 can be grounded to the rack through the mounting brackets, eliminating the need for separate a ground wire.

Cabling Overview

The 2144 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 back plane connectors are standard 50- pin telephone-type receptacle connectors. Each Splitter card uses 24 pairs of the 25 pairs available on each 50-pin connector.

The DSL Interface connectors (J1, J4, J7, J10, J13, & J16) and the LOOP Interface connectors(J2, J5, J8, J11, J14, & J17) are oriented so that the mating plug left-angled cable head will dress out to the left side of the shelf. Whereas, the PSTN Interface connectors (J3, J6, J9, J12, J15, & J18) are oriented so that the mating plug right- angled cable head will dress out to the right side of the shelf.

Connector Pinouts
