Wiring

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

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

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

! Plug 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.

! Dress 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.

! CAUTION:

Be careful not to connect tie trunks to GS, LS, or DID ports. Since all the jacks on the termination block are 8-wire jacks, it is possible to interchange tie trunk wires with GS, LS, or DID wires accidentally.
