Configuring a Non-Protection Ring

How to configure a Non-Protection Ring on Huawei OSN 3500

The Huawei Transmission OptiX OSN equipment supports various network level protection schemes, including the linear MSP and ring MSP. Configuring the Protection Subnet on Huawei SDH. In this article, we will learn how to Configure 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

1 You must be an NM user with NE and network maintainer authority or higher.

2 The NE data must be configured, and fibers must be properly created.

Procedure

Step 1 Choose Service > SDH Protection Subnet > Create Unprotected Ring from the Main Menu to display the Create Protection Subnet dialog box.

Step 2 Enter the name of the protection subnet.

The default name is usually used, for example, NP_Ring_1.

Step 3 Select the rate of the protection subnet,

for example, STM-4.

Step 4 Select Resource Sharing and Assigned by VC4 as needed.

NOTE

1 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.

2 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.

3 OptiX OSN 1500/2500/3500/3500 II/7500 /7500 II do not support Transoceanic Protocol

Step 5 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.

Step 6 Click Next to proceed to the Select Link screen of the wizard. Set parameters, such as Physical Link Information.

NOTE

1 If there are multiple fibers between two NEs, select them from the Physical Link Information dropdown list.

2 If Assigned by VC4 is selected, you can select the working and protection VC4 timeslots as needed.

Step 7 Click Finish to deliver the configuration data. Then the Operation Result prompt box is displayed. Click Close.
