TESTING TIE LINES

Testing Outgoing and

Two-way Automatic

Ringdown Tie Lines

Use any voice terminal in the system to test the ability to place outside calls on each outside line as follows:

1 Lift the handset.

The green light goes on next to the red light.

2Dial the outside number of someone you know will answer the call.

3Verify two-way communication and then hang up.

4Repeat the procedure for each of your outside line telephone numbers.

Before making these tests, make sure that the tie lines for the system are connected and properly configured.

NOTE: Refer to "Tie Line Troubleshooting" on page 4-11 if you have any problems with tie line installation or testing.

Before testing Outgoing or Two-way Automatic Ringdown tie lines, or automatic start tie lines, arrange to have someone waiting at the automatic ringdown console to receive your call. The automatic ringdown console is the voice terminal on which automatic ringdown tie line calls are received. Follow these steps:

1 At any voice terminal that has a tie line appearance, press the first tie line button.

The red light jumps to the tie line button just pressed.

2 Lift the handset.

The green light goes on next to the red light and you hear ringing.

3Verify two-way communication and then hang up.

4Repeat this procedure for each tie line administered.
