Installing Telephones and Adjuncts

Telephone Installation Procedure

1.Run the DIW cable from the control unit to the telephone and cut it. Allow enough slack for routing the wire.

2.Attach a Unicon plug to the control unit end of the DIW cable by using the 4-pair plug presser.

3.Plug the DIW cable into the control unit and connect the other end to the telephone jack. See “Terminating Cable at a Telephone Outlet” later in this chapter.

4.Repeat Steps 1 through 3 for each telephone line.

5.Route the wires properly by using cable ties. Fasten wire runs vertically to the left or right of the control unit. The final horizontal wire run to the control unit must be fastened within 12 inches (30 cm) of the control unit. Allow sufficient slack to reach any port on the control unit.

6.Label the control unit module jacks, telephone jacks, and DIW cables properly. See “Label the System Wiring” later in this chapter.

Connecting More than 24 Telephones

For systems with more than 24 telephones, the two recommended methods are Interconnect Wiring and SYSTIMAX as described later in this chapter.

Interconnect Wiring

Interconnect Wiring is required when the system has more than 24 telephones and SYSTIMAX has not been ordered. The Interconnect Wiring module provides the hardware to interconnect up to 12 telephones with 110-type wiring.

For Interconnect Wiring, you must build a jack field between the control unit and the telephones by using 110AB1-100JP12 termination blocks with modular jacks and 110A1 wire troughs.
