Step 7
For all nodes, if the card is in service, use an optical test set to determine whether signal failures are
present on fiber terminations. For specific procedures to use the test set equipment, consult the
manufacturer.
Caution
Using an optical test set disrupts service on the OC-N port. It could be necessary to manually switch
traffic carrying circuits over a protection path. See the
“1.10.1 Protection Switching, Lock Initiation,
and Clearing” section on page 1-148
for commonly used switching procedures.
Step 8
If no signal failures exist on terminations, measure power levels to verify that the loss is within the
parameters of the receiver. Refer to the
Cisco ONS 15310-CL and Cisco ONS 1310-MA Reference
Manual
for card power levels.
Step 9
If loss is within parameters, ensure that fiber connectors are securely fastened and properly terminated.
Step 10
If fiber connectors are properly fastened and terminated, complete the
“Soft- or Hard-Reset a Controller
Card” procedure on page 1-154
.
Caution
Avoid soft-resetting multiple ONS 15310-MA cards at one time; doing so might cause an unexpected
traffic hit.
Wait ten minutes to verify that the card you reset completely reboots.
Step 11
If the controller card reset does not clear the alarm, delete the problematic SDCC termination by
completing the following steps:
a.
From card view, click
View > Go to Previous View
if you have not already done so.
b.
Click the
Provisioning > Comm Channels > SDCC
tabs.
c.
Highlight the problematic DCC termination.
d.
Click
Delete
.
e.
Click
Yes
in the Confirmation Dialog box.
Step 12
Recreate the SDCC termination. Refer to the “Turn Up Network” chapter in the
Cisco ONS 15310-CL
and Cisco ONS 15310-MA Procedure Guide
for procedures.
Step 13
Verify that both ends of the DCC have been recreated at the optical ports.
Step 14
If the alarm has not cleared, call Cisco TAC (1 800 553-2447).
1.7.57 EOC-L
Default Severity: Minor (MN), Non-Service-Affecting (NSA)
SONET Logical Object: OCN
The Line DCC (LDCC) Termination Failure alarm occurs when the ONS 15310-CL or ONS 15310-MA
loses its LDCC termination. The LDCC consists of nine bytes, D4 through D12, that convey information
about OAM&P and network management information in the SONET overhead.
