Huawei Transmission: Configuring the Built-in WDM Service

OptiX OSN 7500 II/ OSN 7500/ OSN 3500/ OSN 1500 Configuration Guide:

Configuring the Built-in WDM Service

Basic Concepts

The built-in Huawei WDM system that is composed of the LWX and MR2 boards can add

and drop any two wavelengths within the range from 34 Mbit/s to 2.7 Gbit/s and can add

and drop four wavelengths by using the concatenation technology. In addition, the built-in

WDM system can implement the optical channel protection by using the dual-fed and

selective-receiving function of the LWX boards.

LWX and MR2 boards (without the optical channel protection)

Networking Diagram

This topic describes the service requirements and board layout information of the built-in

WDM services between NE1 and NE2. Before you learn the service signal flow and

configure the builtin WDM services, you need to be familiar with the networking diagram.

Service Requirements

The requirements for the built-in WDM services between NE1 and NE2 are as follows:

l Two wavelengths must be added to or dropped from NE1 and NE2.

l The line services must be configured with the 1+1 optical channel protection.

NOTE

This topic considers the board layout of the OptiX OSN 3500 as an example to describe

the service configuration. The service configuration on other products is the same as the

service configuration on the OptiX OSN 3500. The only difference is that the boards may

be inserted in different slots. For the board layout information of a specific product, see

the corresponding Hardware Description.

Board Layout

According to the service requirements, the NE needs to be configured with two MR2A

boards and two LWX boards. The LWX boards are available in two types: single-fed and 2

singlereceiving board and dual-fed and selective-receiving board. In this example, the

LWX boards support the dual-fed and selective-receiving function.

Configuration Process

The built-in WDM system is used to add and drop wavelengths at any rate and provide

protection for the wavelengths. This topic describes how to configure the built-in WDM

service.

Prerequisites

l The 2 Creating the Network task must be completed.

l The fibers and cables of the LWX and MR2 boards must be connected correctly.

l You must be familiar with the information of 10.3 Signal Flow and Timeslot

Allocation.

Procedure

Step 1 To configure the WDM Interface of the LWX board, do as follows:

1. Select the 1-LWX board in the NE Explorer, and then choose Configuration > WDM

Interface from the Function Tree.

2. Select By Board/Port(Path) and select Board from the drop-down list. Click Query.

Check whether the board receiving/transmitting attribute is Dual-Fed-Selective-

Receiving.

3. Select Channel from the drop-down list. Click the Basic Attributes tab. Check

whether

the status of the laser at each port is Open. Normally, the default value is adopted. Click

Apply.

4. Perform the same operations to check the settings of the WDM ports on the other LWX

boards of NE1 and NE2.

Step 2 To configure the wavelength protection group, do as follows:

1. Select NE1 in the NE Explorer, and then choose Configuration > Wavelength

Protection Group from the Function Tree.

2. Click New, and the Create Wavelength Protection Group dialog box is displayed.

Set

the parameters in the dialog box, as listed in the following table. Click Apply.

3

3. Perform the same operations to configure the wavelength protection group of the LWX

board in slot 2 of NE1.

4. Perform the same operations to configure the two wavelength protection groups of

NE2.

Step 3 See Enabling, Disabling and Setting Performance Monitoring of the NE and

enable the performance monitoring function of the NEs.

Step 4 Back up the configuration data of the NEs. For details, see Backing Up the NE

Configuration Data to the SCC Board.
