the values lockout, forcedSwitch, or manualSwitch can be present at the same
time, either local or remote. It is also possible to have two or more
pending automatic switch requests. The protectionStatus attribute of a
protection Unit which provides protection is used to hold the protection
request which is actually performed on that protectionUnit.
Locally invoked management operations (e.g. manual, forced, lockout switch
completions) can be overridden at the near end or the far end, but may only
be released at the near end.
Single-ended systems keep the status of local and far-end switch requests as
separate entities in the protectionStatus attribute.
The remainder of this behaviour provides the allowable protectionStatus
attribute values for protected and protecting units for both revertive and
non-revertive systems. The following allowable protectionStatus values are
associated with each protected unit:
( No Request ( No switch request is present on the unit.
( Manual Switch to Protecting Complete ( The unit has completed a Manual Switch.
( Release failed ( A switch has been released or pre-empted and a timeout
occurs while waiting for a release of associated bridges, or the near-end switch.

( The switch from protected to protecting or protecting to protected has
been done without pre-empting an existing switch. In this case the old and
new values of the Protection Status attribute of the protecting channel
shall be reported in the notification by means of the oldProtectionStatus

channel shall be reported in the notification by means of the
oldProtectionStatus and newProtectionStatus parameters respectively.
( An auto-switch condition exists on a channel but the auto-switch cannot be
served due to the unavailability of the channel that otherwise protects
it. In this case the oldProtectionStatus and newProtectionStatus
parameters refer to the protection status attribute value of the channel
on which the autoswitch condition arises. The exception is when the
channel is already forced or locked out, in which case no notification is sent.
( A working channel (protected unit) has been locked out or released from
lockout without modifying any existing switch. In this case the
oldProtectionStatus and newProtectionStatus parameters refer to the
protection status attribute value of the working channel which has been
locked out.
( A protection channel (protecting unit) has been locked out or release from
lockout without modifying the existing switch. In this case the
oldProtectionStatus and newProtectionStatus parameters refer to the
protection status attribute value of the protection channel which has been
locked out.
( The protectionSwitchReporting is not sent when the automatic switch
