If a newly created circuit has no signal, a UNEQ-P alarm is reported on the OC-N cards and the AIS-P condition
is reported on the terminating cards. These alarms clear when the circuit carries a signal. Note
Clear the UNEQ-P Alarm
SUMMARY STEPS
1. In node view, choose
Go to Network View
from the View menu.
2. Right-click the alarm to display the Select Affected Circuits shortcut menu.
3.
Click Select Affected Circuits .
4. When the affected circuits appear, look in the Type column for VTT, which indicates a VT tunnel circuit.
A VT tunnel with no VTs assigned could be the cause of an UNEQ-P alarm.
5.
If the Type column does not contain VTT, there are no VT tunnels connected with the alarm. Go to
Step 7, on page 425 .
6. If the Type column does contain VTT, attempt to delete these rows:
7. If all nodes in the ring appear in the CTC network view, determine whether the circuits are complete:
8.
If you find circuits listed as PARTIAL, use an optical test set to verify that these circuits are not working
circuits that continue to pass traffic. For specific procedures to use the test set equipment, consult the
manufacturer.
9. If the PARTIAL circuits are not needed or are not passing traffic, delete the PARTIAL circuits.
10. Recreate the circuit with the correct circuit size. Refer to the Create Circuits and VT Tunnels chapter
in the Configuration guide.
11.
Log back in and verify that all circuits terminating in the reporting card are active:
12. If the alarm does not clear, clean the far-end optical fiber according to site practice. If no site practice
exists, complete the procedure in the Maintain the Node chapter of the Configuration guide.
13.
If the alarm does not clear, complete the Physically Replace a Card, on page 453 procedure for the OC-N
and electrical cards.
DETAILED STEPS
Step 1
In node view, choose Go to Network View from the View menu.
Step 2 Right-click the alarm to display the Select Affected Circuits shortcut menu.
Step 3 Click Select Affected Circuits .
Step 4
When the affected circuits appear, look in the Type column for VTT, which indicates a VT tunnel circuit. A VT tunnel
with no VTs assigned could be the cause of an UNEQ-P alarm.
Step 5 If the Type column does not contain VTT, there are no VT tunnels connected with the alarm. Go to Step 7, on page
425 .
Step 6
If the Type column does contain VTT, attempt to delete these rows:
The node does not allow you to delete a valid VT tunnel or one with a valid VT circuit inside. Note
a) Click the VT tunnel circuit row to highlight it. Complete the Delete a Circuit, on page 454 procedure.
b) If an error message dialog box appears, the VT tunnel is valid and not the cause of the alarm.
c) If any other rows contain VTT, repeat
