is to prevent the possibility a loop forming in the event that two or more R-APS signal fail
messages are sent simultaneously from different ends of the ring.
Tick the check box and enter the wait-to-restore (WTR) time of the R-APS function. The WTR
time defines the amount of time mandated to pass after conditions clear. After the WTR time
expires, the RPL returns to idle state (blocking). This is used to prevent too frequent operation
of ERPS due to an intermittent signal failure defect.
