This attribute specifies whether revertive switching is to be used. It
has possible values of no or yes.
When this attribute is no, the Aps will not revert the receive active
line from protection back to working when a working line request is
cleared.
When this attribute is yes, the Aps will revert the receive active line
from protection back to working when a working line request is
cleared, after the provisioned waitToRestorePeriod has expired.
Note that it is acceptable for the near end and far end to be
provisioned with a mix of revertive and nonrevertive switching.
