Configuring a Non-Protection Chain
If a service in the chain does not need to be protected, you can configure a non-protection chain. In this case, all the timeslots in the chain can be used to transmit the service.
Prerequisites
You must be an NM user with NE and network maintainer authority or higher.
On the NM, the data of each NE must be configured, and fibers must be created correctly.
Procedure
- Choose Service > SDH Protection Subnet > Create Unprotected Chain from the Main Menu to display the Create Protection Subnet dialog box.
- Enter the name of the protection subnet. Generally, enter the default name, for example, non-protection chain_1.
- Select the capacity level of the protection subnet, for example, STM-4.
- Select Resource Sharing and Assigned by VC4 as needed.
NOTE:
If multiple protection subnets use one port of a board, you need to check the Resource Sharing check box. If MSP Sharing is enabled, you can check the Resource Sharing check box to map a port of the board to multiple MSPs. If different protection subnets use different ports of a board, do not check this check box.
Select the Assigned by VC4 option when there are different VC4s belonging to different protection subnets to achieve MSP only in some channels protection. For example, for an STM-16 fiber, the VC4s 1-4 belong to an STM-4 MSP, and VC4s 5-8 belong to a PP.
OptiX OSN 1500/3500/7500/7500 II do not support Transoceanic Protocol.
- Select a node to create a non-protection chain. Double-click an NE in the Main Topology and add it to the left node list. At the same time, is displayed on the NE icon. Double-click the NE icon again to cancel the selection.
- Click Next to display the Select Link dialog box. Set parameters, such as Physical Link Information.
- Click Finish to deliver the configuration data. Then the Operation Result prompt box is displayed. Click Close.
Configuring a Non-Protection Ring
When services on a ring do not need protection, you can configure a non-protection (NP) ring. All timeslots on the ring can be used to transmit services.
Prerequisites
You must be an NM user with NE and network maintainer authority or higher.
The NE data must be configured, and fibers must be properly created.
Procedure
- Choose Service > SDH Protection Subnet > Create Unprotected Ring from the Main Menu to display the Create Protection Subnet dialog box.
- Enter the name of the protection subnet. The default name is usually used, for example, NP_Ring_1.
- Select the rate of the protection subnet, for example, STM-4.
- Select Resource Sharing and Assigned by VC4 as needed.
NOTE:
If multiple protection subnets use one port of a board, you need to check the Resource Sharing check box. If MSP Sharing is enabled, you can check the Resource Sharing check box to map a port of the board to multiple MSPs. If different protection subnets use different ports of a board, do not check this check box.
Select the Assigned by VC4 option when there are different VC4s belonging to different protection subnets to achieve MSP only in some channels protection. For example, for an STM-16 fiber, the VC4s 1-4 belong to an STM-4 MSP, and VC4s 5-8 belong to a PP.
OptiX OSN 1500/3500/7500/7500 II do not support Transoceanic Protocol.
- Add nodes to the protection subnet to be created. Double-click the NE on the Main Topology and add it to the node list in the left-hand pane. Meanwhile, is displayed on the NE icon. If you want to cancel the selection, double-click the NE again.
- Click Next to proceed to the Select Link screen of the wizard. Set parameters, such as Physical Link Information.
NOTE:
If there are multiple fibers between two NEs, select them from the Physical Link Information drop-down list.
If Assigned by VC4 is selected, you can select the working and protection VC4 timeslots as needed.
- Click Finish to deliver the configuration data. Then the Operation Result prompt box is displayed. Click Close.
