Protection section

WTR (wait to restore)
WTR is the wait to restore time after the failure on the protected unit has cleared.
WTR (Wait to restore/Wait to rename)
Defines either the Wait to Restore Time or the Wait to Rename Time.
If MSP mode is ETSI, then WTR is the wait to restore time after the failure on the
protected unit has cleared. If MSP mode is 1+1 optimized, then WTR is the Wait to
rename: after the failure on the protected unit has cleared, the traffic remains on the
protection, but the current primary becomes secondary and the other way around.
Values are 0..60
