How to Configure 10GE LAN Services by Using the TDX and NS2 Boards (2)?

Configuration Process

This section describes how to configure a bidirectional 10GE LAN service at stations A, B, and C.

Prerequisite

You are an NMS user with "Operator Group" authority or higher.

Tools, Equipment, and Materials

U2000/Web LCT (U2000 is recommended)

Background Information

• The port mapping mode of 10GE LAN services can be configured as Bit Transparent Mapping (11.1 G) or MAC Transparent Mapping (10.7 G). Users can select a proper mapping mode according to the service transmission requirements.
  • Bit Transparent Mapping (11.1 G) meets customer requirement for transparent bit transport of 10GE LAN signals. In the Bit Transparent Mapping (11.1 G) mode, transmission of signals are achieved by increasing the OTU frame frequency. This ensures the encoding gain and correction capability of FEC. In this mode, however, the bit rate is higher than the standard bit rate of OTU2 signals.
  • MAC Transparent Mapping (10.7 G) is specific to transparent transmission of 10GE MAC frames as required by customers. In this port mapping mode, a 10GE LAN signal is encapsulated in the GFP-F format and then mapped into a standard OTU frame. This mode supports transparent transmission of only client 10GE MAC frames. In this mode, the signals are in standard OTU2 frames. In addition, the FEC/AFEC code pattern is applicable to 10GE LAN services in this mode. Originally, the FEC/AFEC code pattern is intended for 10G SDH services.
• The port mapping modes of the upstream and downstream board must be the same.

Procedure on the U2000/Web LCT

Configure attributes of client-side ports on the TN52TDX board of station A.

1. In the NE Explorer, select the TN52TDX board that you want to configure, and then choose Configuration > WDM Interface from the Function Tree.
2. Click By Board/Port (Channel), and select Channel from the drop-down list.
3. Select the Basic Attributes tab.
4. Select the ClientLP port, the service type that needs to be set, and then double-click the corresponding parameter domain to set the following parameters.
   • Service Type: 10GE LAN
   • Port Mapping: Bit Transparent Mapping (11.1G)
5. Click Apply. In the dialog box that is displayed, click OK.
6. Click Query. Ensure that the query result is consistent with the configuration.

2, Configure attributes of client-side ports on the TN52NS2 board of station A.

a, In the NE Explorer, select the TN52NS2 board and choose Configuration > WDM Interface from the Function Tree.

b, Click By Board/Port (Channel), and then choose Channel from the drop-down list.

c, Select the Basic Attributes tab.

d, Select the ODU2LP port. Double-click the Service Mode parameter and then select ODU2 or Automatic.

e,On the Advanced Attributes tab, select the ODU2LP port and then double-click the Line Rate parameter and select Speedup Mode.

3, Repeat step 2 to configure attributes of ports on the TN52NS2 board at station B.

4, Repeat steps 1 and 2 to configure attributes of ports on the TN52TDX and TN52NS2 boards of station C.
5, Configure ODU2 services between the TN52NS2 board and the TN52TDX board at station A.
6, Click Query. Ensure that the query result is consistent with the configuration.
7, Configure ODU2 services between the TN52NS2 boards at station B.
8, Click Query. Ensure that the query result is consistent with the configuration.
9, Configure ODU2 services between the TN52NS2 board and the TN52TDX board at station C.
10,Click Query. Ensure that the query result is consistent with the configuration.

Configuration Networking Diagram

Service Requirement

The optical NEs (ONEs) A, B, C, and D form a ring network. All the ONEs function as OADM stations.

User1 and User2 communicate with each other. One bidirectional 10GE LAN service is available between station A and station C. At station A, the TN52TDX board accesses one 10GE LAN service and encapsulates the 10GE LAN service into one channel of ODU2 electrical signals, that is, one ODU2 service. The TN52NS2 board accesses the ODU2 service and then outputs one OTU2 service. Station B transparently transmits the OTU2 service. At station C, the TN52NS2 board accesses the OTU2 service and converts the OTU2 service into ODU2 electrical signals, which are groomed to Huawei TN52TDX board and then output as one 10GE LAN service.

Service Signal Flow

One bidirectional GE service is available among stations A, B, and C.

Service at each station 

ClientLP and ODU2LP are logical ports. There are cross-connections between client-side RX/TX ports and ClientLP ports and therefore cross-connections do not need to be configured. ODU2 cross-connections between the ClientLP ports of Huawei TDX board and the ODU2LP ports of the NS2 board need to be configured. There are connections between the ODU2LP ports of the NS2 board and WDM-side IN/OUT ports and therefore cross-connections do not need to be configured.
