Optix OSN1500 Creating Ring-Multiplexed Segment Protection Subnet

Ring Multiplexed Segment Protection is mainly applicable in the ring grouping of public (normally protects the channel to pass additional services), and by running the APS protocol, you can realize the protection at the level of multiplexed segments.

Prerequisites

The user has "Network element and its network maintainer" or higher network administrator user privileges.

The data for each network element has been configured on the network administrator and the fibers have been created correctly.

Background information

The number of nodes in a multiplexed segment protection ring cannot exceed 16.

When creating a protection subnet, only SDH network elements can be selected, not soft relay ( REG ) or wavelength division ( WDM ) devices.

Note:

Starting a protocol controller operation may cause service interruption.

Procedure

In the main menu, select "Service > SDH Protection Subnet > Create Dual-Fiber Bidirectional Multiplexing Segment Shared Protection Ring", and a prompt dialog box will pop up. Click "OK" to enter the "Create Protection Subnet" page.

Description:

If you want to create a shared protection ring for quad-fiber bi-directional multiplexed segments, you can select "Service > SDH Protection Subnet > Create Shared Protection Ring for Quad-Fiber Bi-Directional Multiplexed Segment" in the main menu to enter the corresponding creation page.

If you want to create a dedicated protection ring for 2-fiber unidirectional multiplexing segment, select "Service > SDH Protection Subnetwork > Create 2-fiber Unidirectional Multiplexing Segment Dedicated Protection Ring" in the main menu to enter the corresponding creation page.

Enter the name of the protection subnet. Usually, you can use the default name, for example: 2-Fiber Unidirectional Multiplexing Segment Shared Protection Ring_1.

Select the capacity level of the protection subnet. For example: STM-4.

Select "Resource Sharing" and "Segment by VC4 " as required.

Description:

The essence of "Resource Sharing" is to map the same single board port to multiple protection subnets. When there are multiple protection subnets occupying the same port of the same single board, "Resource Sharing" must be selected, but for different protection subnets occupying different ports of a single board, "Resource Sharing" does not need to be selected. If you enable single-optical port multi-multiplexing segment, you can also map a single board port to multiple multiplexing segments through "Resource Sharing".

"Segmentation according to VC4 " means that different VC4s are assigned to different protection subnets, and its function is to realize partial multiplexing segment protection. For example, an STM-16 fiber can be divided with the 1st to 4thVC4s belonging to an STM-4 multiplexing segment sharing protection and the 5th to 8thVC4s belonging to an unprotected ring.

The OptiX OSN 1500/2500/3500/3500 II/7500 does not support the Trans Ocean Protocol.

Select the nodes to be included in the protection subnet to be created. Double-click on the selected network element in the main topology to add it to the list of nodes on the left side and to display it on the icon of the network element (double-click on the network element again to cancel the setting).

Description:

For ease of maintenance, it is recommended that nodes be added in counterclockwise order.

Set the attribute of each node to " MSP Node".

Click "Next" to enter "Link Selection" to set the link physical information and other parameters.

Description:

If there are multiple fibers between two network elements, you can specify the Link Physical Information by selecting it in the drop-down list box.

If it is "Split by VC4 ", you can select the working VC4 time slot and the protection VC4 time slot as needed.

Click "Finish" to send the configuration, the system pops up the "Operation Result" prompt box, click "Close".

Right-click on the protection subnet and select "Properties of Protection Subnet" in the pop-up context menu.

Click the Protected Subnet Maintenance tab to confirm that the Protocol Controller is up.

If the protocol controller is not up, do the following:

Select all network elements of the protection subnet.

Right-click and select Start/Stop Protocol > Startup in the pop-up context menu.

Double-click "Yes" in the prompt box to put all Protocol Controllers in the "Protocol Startup" state.

Click the Protected Subnet Parameters tab, and set the Inversion Recovery Waiting Time and SD Trigger Condition as required. Click Apply to distribute the configuration. In the same protection subnet, the settings of "Reverse Recovery Waiting Time" should be the same for each network element.

Description:

The default value is 600 seconds.
