The Wait To Restore period in seconds.
After clearing of a condition that necessitated an
automatic switch, the wait to restore period must elapse
before reverting. This is intended to avoid rapid switch
oscillations.
GR-253-CORE specifies a Wait To Restore range of 5 to 12
minutes. G.783 defines a 5 to 12 minute Wait To Restore
range in section 5.4.1.1.3, but also allows for a shorter
WTR period in Table 2-1,
WaitToRestore value (MI_WTRtime: 0..(5)..12 minutes).
