Description |
|---|---|
Start Protocol |
Enables the switching protocol. |
Stop Protocol |
Stops the switching protocol. |
Query Switching Status |
Queries the switching status. |
Clear |
Clears the switching status. |
Force Switching |
Switches a PW forcibly, regardless of the status of the PW. |
Manual Switching to Working |
Performs manual switching from the protection PW to the working PW. If the working PW is normal, the switching takes place. If the working PW fails or must meet a switching request of higher priority, the switching does not take place. |
Manual Switching to Protection |
Performs manual switching from the working PW to the protection PW. If the protection PW is normal, the switching takes place. If the protection PW fails or must meet a switching request of higher priority, the switching does not take place. |
Exercise Switching |
Simulates the switching operation. It is not a real switching. This function tests the function of the protection group and does not interrupt services. |
Lockout of Protection |
The switching request for the PW is denied, but the reversion of the switching is allowed. |
Clear Slave Protection Pair |
Delete the protection pair that belongs to the PW APS protection group. |
Field |
Value |
Description |
|---|---|---|
Protection Group ID |
1 to 1024 |
Indicates the ID of a protection group. NOTE:
If a protection pair is bound to a PW APS protection group, the ID of the protection pair is the ID of the PW APS protection group. |
Peer Protection Group ID |
1 to 1024 |
Indicates the ID of a peer protection group. NOTE:
For the inter-NE protection, you need to specify the ID of the protection group of the peer NE. In this way, the protection groups on both ends can negotiate and together implement
the inter-NE PW protection. |
Protection Type |
MC PW APS, PW APS |
Indicates the protection type of a protection group. |
Protection PW ID |
For example: 321 |
Indicates the ID of the protection group. |
Working PW ID |
For example: 123 |
Indicates the ID of the working PW. |
DNI PW ID |
For example: 4321 |
Indicates the ID of a DNI PW. |
Protection Mode |
1+1, 1:1 |
When the protection type is 1+1 protection, the service is in the dual-fed and selective-receiving mode. When the protection type is 1:1 protection, the service is in the single-fed and single-receiving mode. |
Switchover Mode |
Single-ended switching, Dual-ended switching |
Indicates the switching status of a protection group. |
Revertive 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. |
Switchover WTR Time (min) |
1 to 12 |
Specifies the wait-to-restore time of the switching. Switchover WTR time is the period between when the working PW recovers and when the services are restored to the working PW. NOTE:
Only when Revertive Mode is set to Revertive, Switchover WTR Time is available. |
Switchover 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. |
Protection Group Status |
Enabled, Disabled |
Indicate whether a protection group is enabled. |
Deployment Stauts |
Deployed, Undeployed |
Display the deployment status of the PW. |
Switchover 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. |
Indicates the switching status of a protection group. |
Protocol Status |
Enabled, Disabled |
Enables or disables the protocol. When the protocol is enabled, the protection group takes effect. |
Activation Status |
Active, Inactive |
An active protection group is saved on the Web LCT and the settings of the group are applied to NEs. An unactive protection group is saved only on the Web LCT. |
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. |
PW Type |
For example: ATM n to one VCC cell transport |
Display the PW encapsulation type. |
Deployment Status |
Deployed, Undeployed |
Display the deployment status of the protection group. |
