This read-only Unsigned32 value, in seconds (0-3600, default 300), is the Wait-To-Restore timer: how long a repaired working path must remain healthy before revertive switching moves traffic back to it, with 0 meaning switch back immediately. Operators care because a well-tuned WTR avoids 'flapping' traffic back and forth if a fault is intermittent. For example, with opsWaitToRestore at 300 seconds, traffic that switched to protection during a brief fiber flap will not return to the working path until that path has stayed clean for a full five minutes.
