Enumeration
The reason why APS switch happened. When the working
line on one end fails, its other end is told to do
an APS switch. The following options in the increasing
order of priority indicate what type of switch request
it is.
slSonetApsRevertive : Switch back to working line after the
Wait-to-Restore interval is over, and failures are
cleared. It is the lowest priority.
slSonetApsManual : Manual switch causes APS switch unless a
request of equal or higher priority is in effect.
slSonetApsSignalDefectLow : Switch happened because threshold
for 'slSonetApsSigFaultBER' was exceeded.
slSonetApsSignalDefectHigh : Same as above, but higher priority.
slSonetApsSignalFailureLow : Switch happened because threshold
for 'slSonetApsSigDegradeBER' was exceeded.
slSonetApsSignalFailureHigh : Same as above, but higher
priority.
slSonetApsForceSwitch : Forced switch forces hardware to switch
the active line even if the other line (could be
working line or protection line) is in alarm.
slSonetApsLockOut : This is the highest priority switch. This
will override all other requests.
slSonetApsRemoteRequest : indicates that the local switchover
was in response to a remote request to switch.
slSonetApsLockOut : indicates that the last switchover to the
working occurred because of protection lockout.
