Configuration Guide

2.6.1 Configuring a Non-Protection Chain

If the services on a chain do not need to be protected, you can configure the chain as a non-
protection chain. In this case, all the timeslots on the chain can be used to transmit the services.
2.6.2 Configuring a Non-Protection Ring
When services on a ring need not be protected, you can configure a non-protection (NP) ring.
All timeslots on the ring can be used to transmit services.
2.6.3 Creating an MS Ring Protection Subnet
Generally, the MS ring protection is configured on the public ring network whose protection
paths are used to transmit extra services. By running the APS protocol, it achieves the MS level
protection.
2.6.4 Creating a Linear MS Protection Subnet
In a chain network, an NE can protect the services in different fiber sections after a linear MS
protection subnet is created.

Procedure
Step 1 Choose Service > SDH Protection Subnet > Create Unprotected Chain from the Main Menu.
Then, the Create Protection Subnet dialog box is displayed.
Step 2 Enter the name of the protection subnet.
Generally, enter the default name, for example, NP_Chain_1.
Step 3 Select the capacity level of the protection subnet,
for example, STM-4.
Step 4 Optional: Select Resource Sharing and Assigned by VC4 as needed.
NOTE
Step 5 Select the NEs where you need to create the non-protection chain. Double-click the NEs in the
Main Topology and add them to the NE list on the left. At the same time,
the NE icons. You can cancel the selection by double-clicking the NE icons again to cancel the
selection.
Step 6 Click Next. Set the parameters such as Physical Link Information.
Issue 02 (2011-06-30)
The data of each NE must be configured and the fibers must be created on the U2000.
You must be an NM user with "network maintainer" authority or higher.
l If multiple protection subnets uses one port of a board, you need to check the Resource Sharing check
box. If different protection subnets use different ports of a board, do not check this check box.
l Select the Assigned by VC4 option when there are different VC4s belonging to different protection
subnets to achieve virtual optical path protection.
