APC state
The APC subtab provides the following information:
Position—The slot number, card, and port for which APC information is shown.
•
Last Modification—Date and time APC parameter setpoints were last modified.
•
Parameter—The parameter that APC last modified.
•
Last Check—Date and time APC parameter setpoints were last verified.
•

•
State—The APC state.
•
A wrong use of maintenance procedures (for example, the procedures to be applied in case of fiber cut
repair) can lead the system to raise the APC Correction Skipped alarm. The APC Correction Skipped
alarm strongly limits network management (for example, a new circuit cannot be turned into IS). The
Force APC Correction button helps to restore normal conditions by clearing the APC Correction Skipped
alarm.
The Force APC Correction button must be used under the Cisco TAC surveillance since its misuse can
lead to traffic loss.
The Force APC Correction button is available in the Card View > Maintenance > APC tab pane in CTC
for the following cards:
• OPT-PRE
• OPT-BST-E
• OPT-BST
OPT-AMP-C
•
OPT-AMP-17C
