Parameters

**Table 1** PW APS, PW FPS
Field	Value	Description
Protection Group ID	1 to 4096	Set the protection group ID.
Working PW ID	For example: 123	Displays the ID of working PW.
Protection PW ID	For example: 321	Displays the ID of protection PW.
Protection Mode	1+1, 1:1	When the protection mode is 1+1 protection, the service is in the dual-fed and selective-receiving mode. When the protection mode is 1:1 protection, the service is in the single-fed and single-receiving mode.
Protection Group Status	Enabled, Disabled	Indicate whether a protection group is enabled.
Switchover Mode	Single-ended switching, Dual-ended switching	Indicates the switching status of a protection group.
Restoration Mode	Non-Revertive, Revertive	Determines whether the services are restored to the original working PW after the fault is removed. If Revertive is selected, the services are restored to the working PW. If Non-Revertive is selected, the services are not restored to the working PW.
WTR Time (min)	1 to 12	Specifies the wait-to-restore time of the switching. WTR time is the period between when the working PW recovers and when the services are restored to the working PW.
Hold-off Time (100 ms)	0 to 100	Specifies the switching delay time. The switching delay time is the period between when a fault is detected and when the switching occurs.
Enabling Status	Enabled, Disabled	Sets the enabling status of the protection group.
Deployment Status	Deployed, Undeployed	Display the deployment status of the protection group. An deployed protection group is saved on the Web LCT and the settings of the group are applied to NEs. An undeployed protection group is saved only on the Web LCT.
Switchover Status	in-work, in-protect	Indicates the switching status of a protection group.
Protocol Status	Working in working tunnel, Working in protection tunnel, The current status is forcibly locked, Forcibly switching status and working in the protection tunnel, Invalid working tunnel \(because the OAM generates an SF alarm\), Invalid protection tunnel \(because the OAM generates an SF alarm\), Invalid working tunnel \(because the OAM generates an SD alarm\), Invalid protection tunnel \(because the OAM generates an SD alarm\), This status is displayed while manually switching to the working tunnel, This status is displayed while manually switching to the protection channel In restoration mode, the working tunnel does not work and switches to the protection tunnel. Then, the working tunnel works and services automatically switch to the working tunnel. Before WTR reaches, this status remains, The switching is not required,This status is remotely displayed while practising switching, This status is displayed while practising switching.	Enables or disables the protocol.
Working Path Status	Available, Unavailable	Indicates the status of the working channel in a protection group.
Protection Path Status	Available, Unavailable	Indicates the status of the protection channel in a protection group.

**Table 2** Slave Protection Pair
Field	Value	Description
Protection Type	Slave Protection Pair	Indicates the protection type of a protection group.
Protection Group ID	1 to 1024	Specifies the ID of a protection group. NOTE: If a protection pair is bound to a PWprotection group, the ID of the protection pair is the ID of the PW protection group.
Working PW ID	For example: 123	Indicates the ID of the working PW.
Protection PW ID	For example: 321	Indicates the ID of the protection PW.
DNI PW ID	For example: 4321	Indicates the ID of a DNI PW.
PW Type	For example: CESoPSN	Sets the PW type.
Deployment Status	Deployed, Undeployed	Display the deployment status of the protection group. An deployed protection group is saved on the Web LCT and the settings of the group are applied to NEs. An undeployed protection group is saved only on the Web LCT.

**Table 3** PW Redundancy
Field	Value	Description
Redundant Protection Group ID	1 to 1024	Specifies the ID of a protection group.
Working PW ID	For example: 123	Indicates the ID of the working PW.
Protection PW ID	For example: 321	Indicates the ID of the protection PW.
Protection Type	1+1, 1:1	Indicates the protection type of a protection group.
Deployment Status	Deployed, Undeployed	Displays the deployment status of the protection group. An deployed protection group is saved on the Web LCT and the settings of the group are applied to NEs. An undeployed protection group is saved only on the Web LCT.
Working Status	Forward, Not Forward	Indicates the status of the working PW.
Protection Status	Forward, Not Forward	Indicates the status of the Protection PW.
