9.7 Conguring a Non-Protection Ring

When services on a ring need no protection, you can congure a non-protection (NP) ring. All timeslots on the ring can be used to transmit services.

Operator Guide 9 Conguring Protection Subnets

Prerequisites

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

n NE data must be congured, and bers must be correctly created.

Procedure

Step 1 Select Conguration > Protection View from the Main Menu. In the Protection View, select Protection View > Create SDH Protection Subnet > NP Ring. The Wizard for creating non-protection ring is displayed.

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 Assigned by VC4 and Resource Sharing as needed.

NOTE

n Select the Resource Sharing option when the same port of a board is used by multiple protection subnets. If different protection subnets use different ports of a board, this option is not mandatory.

n Select the Assigned by VC4 option when there are different VC4s belonging to different protection subnets in order to achieve virtual optical path protection. For example, for an STM-16 ber, the VC4s 1–4 belong to an STM-4 MSP, while VC4s 5–8 belong to a PP.

Step 5 Add nodes to the protection subnet to be created. Double-click the NE on the Protection View and add it to the left-hand node list. Meanwhile, is displayed on the NE icon.

Step 6 Click Next to proceed to the Select Link screen of the wizard.

Step 7 Click Finish.

The created protection subnet is displayed on the Protection View.

9.8 Conguring Non-Protection Chains

You can create a non-protection chain by wizard.

9.8.1 Creating a Non-Protection Chain

When services on a link need no protection, you can congure a non-protection (NP) chain.

All timeslots on the link can be used to transmit services.

9.8.217.5 Changing an NP Chain to a 1+1 Linear MSP

The T2000 allows you to change some protection types without interrupting services, deleting existing services from the protection subnet, and changing the trail name and other attributes.

To facilitate network management and maintenance, you can change a non-protection (NP) chain to a 1+1 linear MSP.

Step 6 Select the nodes contained in the non-protection chain to be created. Double-click the NE on the Protection View and add it to the left-hand node list. Meanwhile, is displayed on the NE icon. If you want to cancel the selection, double-click the NE again.

Step 7 Click Next to proceed to the Select Link screen of the wizard.

Step 8 Click Finish.

The created protection subnet is displayed on the Protection View.

Operator Guide 9 Conguring Protection Subnets

To facilitate network management and maintenance, you can change a non-protection (NP) chain to a 1+1 linear MSP.

Prerequisites

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

n Both of the two NEs are release 5.0 NEs, congured with data correctly. The two NEs must also be working normally.

n At least two bers of the same class exist between the two NEs and are not occupied by other protection subnets such as PP, MSP, NP ring, or NP chain with more than two nodes.

n There must be no service on the protection chain.

Procedure

Step 1 Select Conguration > Protection View from the Main Menu. In the Protection View, select Protection View > SDH Protection Type Change. The protection type change wizard is displayed.
