Description 1
Description 2
This attribute is used to indicate the status of the protection switch in a protectionUnit instance. This attribute is set-valued because some requests are allowed to be pending. The following rule shall be followed: Only one of 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. ( Automatic Switch (SF) Pending ( The unit has a Signal Fail condition present and the protecting unit is unavailable. ( Automatic Switch (SD) Pending ( The unit has a Signal Degrade condition present and the protecting unit is unavailable. ( Automatic Switch (SF) Complete ( The unit has completed an Automatic Switch to the protecting unit due to a Signal Fail condition. ( Automatic Switch (SD) Complete ( The unit has completed an Automatic Switch to the protecting unit due to a Signal Degrade condition. ( Automatic Switch (SF) Present, Operate failed ( An automatic switch (SF) request is in progress and a time-out occurs while waiting for completion. ( Automatic Switch (SD) Present, Operate failed ( An automatic switch (SD) request is in progress and a time-out occurs while waiting for completion. ( Force Switch Complete, Automatic Switch (SF) Pending ( The unit has completed a Force Switch. Additionally, the unit has an automatic switch (SF) pending. ( Force Switch Complete, Automatic Switch (SD) Pending ( The unit has completed a Force Switch. Additionally, the unit has an automatic switch (SD) pending. ( Automatic Switch Complete, Wait-to-Restore ( The unit has completed an Automatic Switch to the protecting unit. ( Force Switch Complete ( The unit has completed a Force Switch to the protecting unit. ( Protected Unit Lockout Completed ( The unit has been locked out from the protecting unit. ( Protected Unit Lockout complete, Operate Failed ( The unit has been locked out from the protecting unit, and, the previously completed switch could not be released within the expected time-out. When the switch is released, the operate failed status is removed. Additionally, the non-revertive protected protection unit has the following status values: ( Do Not Revert ( The protected unit has been switched to the protecting unit and the request to do so has been released. The switch to the protecting unit is maintained. ( Manual Switch to Protected Unit Complete ( The unit has completed a Manual Switch from the protecting unit to the protected unit. ( Force Switch to Protected Unit Complete ( The unit has completed a Force Switch from the protecting unit to the protected unit. ( Automatic Switch (SF) to Protected Unit Complete ( The protecting unit has a Signal Fail condition present and traffic is now being carried on the protected unit. ( Automatic Switch (SD) to Protected Unit Complete ( The protecting unit has a Signal Degrade condition present and traffic is now being carried on the protected unit. ( Automatic Switch (SD) to Protected Unit Complete, Signal Degrade Present ( The protecting unit has a Signal Degrade condition present and traffic is now being carried on the protected unit. Additionally, the protected unit has a Signal Degrade condition present. ( Automatic Switch (SF) to Protected Unit Complete, Signal Degrade Present ( The protecting unit has a Signal Fail condition present and traffic is now being carried on the protected unit. Additionally, the protected unit has a Signal Degrade condition present. ( Force Switch from Protecting Unit Complete, Automatic Switch (SF) Pending ( The unit has completed a Force Switch from the protecting unit to the protected unit. Additionally, the protected unit has an automatic switch (SF) condition present. ( Force Switch from Protecting Unit Complete, Automatic Switch (SD) Pending ( The unit has completed a Force Switch from the protecting unit to the protected unit. Additionally, the protected unit has an automatic switch (SD) condition present. The following allowable protectionStatus values are associated with each protecting unit: ( No Request - No request is present on the protecting unit. ( Manual Switch to Protecting Unit Complete ( The protected unit has completed a Manual Switch. ( Automatic Switch Complete (SF) to Protecting Unit ( The protected unit has completed an automatic switch (SF) to the protecting unit. ( Automatic Switch Complete (SD) to Protecting Unit ( The protected unit has completed an automatic switch (SD) to the protecting unit. ( Automatic Switch Complete (SD) to Protecting Unit, Protecting Unit Signal Degraded ( The protected unit has completed an automatic switch to the protecting unit. Additionally, the protecting unit has a Signal Degrade condition present. This applies to 1:n systems only. ( Automatic Switch Complete (SF) to Protecting Unit, Protecting Unit Signal Degraded ( The protected unit has completed an automatic switch to the protecting unit. Additionally, the protecting unit has a Signal Degrade condition present. This applies to 1:n systems only. ( Protecting Unit SD Present ( The protecting unit has a Signal Degrade condition present. This state may also be a result of invalid or toggling APS byte values. This applies to 1:n systems only. ( Protecting Unit SF Present ( The protecting unit has a Signal Fail condition present. This state may also be a result of invalid or toggling APS byte values. This applies to 1:n systems only. ( Force Switch Complete to Protecting Unit ( The unit has completed a Force Switch of a protected unit to the protecting unit. ( Force Switch Complete to Protecting Unit, SD Present on Protecting Unit ( The unit has completed a Force Switch of a protected unit to the protecting unit. Additionally, there is a Signal Degrade present on the protecting unit. ( Force Switch Complete to Protecting, SF Present on Protecting Unit ( The unit has completed a Force Switch of a protected unit to the protecting unit. Additionally, there is a Signal Fail (1 + 1 unidirectional systems only) present on the protecting unit. ( Protecting Unit Locked Out ( The protecting unit has been locked out. ( Protecting Unit Locked Out, Release Failed ( A release of a lockout is in progress and a timeout occurs waiting for the lockout condition to clear. Additionally, the non-revertive protecting unit has the following values: ( Do Not Revert ( The protected unit has been switched to the protecting unit and the request to do so has been released. The switch to the protecting unit is maintained. ( Manual Switch to Protected Unit Complete ( The unit has completed a Manual Switch from the protecting unit to the protected unit. ( Force Switch to Protected Unit Complete ( The protecting unit has completed a forced switch to the protected unit. ( Force Switch to Protected Unit Complete, Protecting Unit Signal Degraded ( The protecting unit has completed a forced switch to the protected unit. Additionally, there is a Signal Degrade condition on the protecting unit. ( Force Switch to Protected Unit Complete, Protecting Unit Signal Failed ( The protecting unit shows a forced switch to the protected unit. Additionally, there is a Signal Fail condition on the protecting unit. ( Automatic Switch (SF) to Protected Unit Complete ( The protecting unit has a Signal Fail condition present and traffic is now being carried on the protected unit. ( Automatic Switch (SD) to Protected Unit Complete ( The protecting unit has a Signal Degrade condition present and traffic is now being carried on the protected unit. ( Automatic Switch Complete (SD) to Protecting, Automatic Switch (SD) to Protected Unit Pending ( The protected unit has completed an automatic switch to the protecting unit. Additionally, the protecting unit has a Signal Degrade condition present. ( Automatic Switch Complete (SF) to Protecting, Automatic Switch (SD) to Protected Unit Pending ( The protected unit has completed an automatic switch to the protecting unit. Additionally, the protecting unit has a Signal Degrade condition present. APS timeout detected by the exerciser, or, during an attempt to invoke a manual or forced switch will not be indicated as APS failure (operate or release fail) in the protectionStatus attribute. Instead, the actionReply for the invoked action will report this. Additionally, attribute lastAttemptResult will provide a record of the failure, until a successful exercise or protection switch causes this attribute to be cleared.
