Wiring

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

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

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

! For each trunk, plug one end of a D2R cord into the designated jack on the termination block and the other end into the line/trunk jack on the proper control unit module.

NOTE:

The modular jacks on the termination block are 8-wire jacks. The

D2R cords, which are 6-wire, also plug into the 8-wire jacks.

! CAUTION:

Do not plug an analog multiline telephone, an MLX telephone, or anything else that should be plugged into an extension jack into this wiring field: doing so will busy-out the trunk.

RJ11 and RJ14 Interfaces

RJ11 and RJ14 interfaces are connected to the control unit similarly.

However, note the following differences:

■RJ11 connects one central office trunk per jack.

■RJ14 connects two trunks per jack.

Plug a 267C-type adapter into each RJ14 jack. You need D2R cords for RJ11 jacks. See Figure 4–5.
