slSonetApsLineSwitchReason

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.
