Testing the System
To test incoming automatic-start tie-trunks, follow the steps below:
1 At the far-end tie-trunk site, have someone pick up the handset and dial a
tie trunk assigned to a button on your telephone.
Your telephone should ring, and the LEDs next to the tie-trunk button should
respond as follows: the red LED should turn on, and the green LED should
flash.
2 Pick up your handset and verify that you have good two-way
communication.
The green LED should change from flashing to steady.
3 At both telephones, hang up.
The green LED should turn off, the red LED should turn off, and another red
LED may turn on.
4 Repeat Steps 1 through 3 for all incoming and two-way automatic-start tie
trunks.
Testing Outgoing Automatic-Start Tie Trunks
Perform this test for automatic-start tie trunks that are two-way or outgoing
only. If you are testing two-way automatic-start tie trunks, perform the
incoming test as well.
To test outgoing automatic-start tie trunks, follow the steps below:
1 At any telephone that has access to an automatic-start tie trunk, press
the first tie-trunk button.
The red LED next to the tie-trunk button just pressed turns on.
2 Pick up the handset. (In Hybrid/PBX systems with pooled tie trunks,
press an SA button and dial the pool dial-out code.)
The green LED next to the selected button turns on, and you hear ringing.
3 When the person answers, verify that you have good two-way
communication and hang up.
The green LED should turn off, the red LED should turn off, and another red
LED may turn on.
4 Repeat Steps 1 through 3 for each outgoing and two-way automatic-start
tie trunk.
