Diagnosing the voice equipment

To diagnose voice channels or cards:

1. Start at the Administration menu, and select Diagnostics > Voice Equipment Diagnostics > Diagnose.
   The system displays the Diagnose Equipment page.
2. Complete the fields on the page. For information about the fields on this page, click Help.
   Caution! Do not diagnose all of the analog-line interface cards or channels at once. This kind of diagnosis can leave no channels available on the system to accept incoming calls.
3. Click Diagnose.
   Depending on the equipment selected, diagnosis can take several minutes. The system displays the Voice Board Diagnostics results page as the system performs the diagnosis.
4. If the system displays either of the following messages, the system did not detect a working telephone line connected to the voice port. If you see either of the following messages, complete Steps a through c.

"No loop current on channel number"

"Channel number changed to state FOOS"

1. Verify that the telephone line is properly connected to both the interface card and the switch.
2. Verify that the analog line is set up properly on the switch.
3. Verify that the switch port has a dial tone. To do so, remove the analog line, plug in an analog telephone, and listen with the handset for a dial tone.

If there is a dial tone, the analog-line interface card is defective. If there is no dial tone, the problem is with the switch. Verify the wiring and administration of the switch.

If the system displays the following message, the system did not detect a dial tone. However, it did detect loop current, which could be a result of excessive load on the analog-line interface card. If you see the following message, complete Steps d and e.

"Diag TR number: No dial tone frequencies set"

4. Verify that the analog lines are distributed over several analog-line interface cards.
5. Verify that the switch administration for the ports is valid.

If the system displays either of the following messages, the channel or card is not working and you must replace the analog-line interface card:

"Channel number changed to state BROKEN"

"Card number changed to state BROKEN"

5. If the card is NONEX (nonexistent), follow the procedures to get inside the PC and verify that the card is properly seated in the slot. If the card is not properly seated, correct the seating of the card and then follow the procedures to return power and replace the PC cover.

6. Click Return to Main to return to the Administration menu.
