AT&T 3.0 manual RJ2GX Interface

Wiring

CAUTION:

Incorrect wiring can damage the ports and cause them to stop functioning. Make sure you use the proper cords. For all GS/LS modules, do the following:

■Use a D2R cable from an RJ11.

■Do not use the Brand-Rex Quad cable from an E66 block.

If you cannot avoid using the Brand-Rex Quad cable, reverse the tip and ring leads at the E66 block to correct the mismatch.

To connect the RJ11 and RJ14 network interfaces to the control unit, follow the steps below:

1Test the central office trunks for proper connection. See “Testing Trunks,” later in this chapter, for instructions.

2Label the network interface jacks, the control unit module jacks, and the D2R cords properly.

See “Labeling Trunks,” later in this chapter, for instructions.

3Plug one end of a D2R cord into the jack at the network interface and the other end into the appropriate line/trunk jack on the control unit.

4Dress the wires properly.

RJ2GX Interface

The RJ2GX is a 25-pair amphenol interface that connects up to 8 tie trunks. Construct the cross-connect field in the same way you did for the RJ21X interface.

RJ21X and RJ2GX interfaces do not require separate termination blocks. If there is room on the termination block for the trunk wires, you can punch down both the RJ21X and the RJ2GX on the same 110AB1 -100JP12 block. Leave any unused wires unterminated.
