Test dial repeating tie lines when someone is available at the far end to place calls to your system. Follow these steps:

1At a preset time, the person at the far end places a dial repeating call to your system by dialing the tie line

number of the voice terminal at which you are waiting.

You hear ringing at the designated voice terminal and the green light flashes next to the button that has the tie line appearance.

2 Lift the handset.

The red light goes on next to the tie line button and the green light becomes steady.

3Verify two-way communication and then hang up.

4Repeat this procedure for each tie line administered.

Completing the Installation

ATTACHING THE CONTROL COVERS

After wiring and testing the system, install the front and top cover on the control unit. (Refer to Figure 2-27.)A set of covers should be installed on both the basic carrier and the expansion carrier. Make sure that there is a module in the rightmost slot of each carrier so that the covers are properly supported. If no functional module occupies the rightmost slot of a carrier, install the empty module that came with the system. Refer to Figures 2-28and 2-29as a guide when attching the covers to the control unit.
