Configuring the Two-Fiber Bidirectional MSP Ring Services

Configuring the Two-Fiber Bidirectional MSP Ring Services

To configure the two-fiber bidirectional MSP service, you need respectively create the MSP subnet protection and MSP services. There is no requirement for the creation sequence.

Networking Diagram

For the two-fiber bidirectional MSP ring in a single ring network, the configuration networking diagram is relative simple. In the network construction, you should create and name NEs in sequence according to the certain direction, which helps you facilitate the planning of the service flow and service configuration.

Figure 6-21 shows a two-fiber bidirectional MSP ring consisting of four NEs. All NEs on the ring use A212 boards for transmitting SDH services.

Figure 6-21 Networking of a two-fiber bidirectional MSP ring

Signal Flow and Timeslot Allocation

When the MSP subnet is created, you can configure the two-fiber bidirectional MSP service that enters the ring network directly from the source NE, passes through the intermediate node and then is dropped on the sink NE. For the ring network service, there is more than one route from the source NE to the sink NE. In actual application scenarios, not all routes need to be configured. Therefore, you should properly plan and configure the service direction and timeslots before the configuration.

Figure 6-22 shows the signal flow and timeslot allocation. In this example, one VC-4 service is added to the ring from NE1 and dropped from NE3, and the service passes through NE2.

Configuration Process

The configuration of the two-fiber bidirectional MSP service is independent of creation of its MSP protection subnet. In the case that the protection subnet is created, you need to respectively configure SDH services from the tributary board to the line board on the source NE and the destination NE, and configure the pass-through service on the intermediate NE.

Prerequisites

  • The physical network topology must be created.
  • NEs, boards, and fibers must be created on the NMS.
  • A protection subnet must be created and be consistent with the actual topology.

Procedure

  1. Configure the MSP service at NE 1.
    1. In the NE Explorer, select an NE and choose Configuration > Ring MS from the Function Tree.
    2. Click Create and click Yes in the Risk dialog box.
    3. In the Create a Multiplex Section Ring dialog box, set the parameters, such as Transmission Level and Protection Type.

      NOTE:
      During the creation of an MSP ring, the setting rules of each MSP node ID are as follows:
      1. Set the NE with the smallest ID in the entire MSP ring as the reference NE.
      2. According the slot IDs of the line boards on the reference NE, set the direction of the MSP ring. The direction of the line board with the smallest ID is west, and that with the biggest ID is the east.
      3. Start from the reference NE and, along the direction of the ring (that is, east), allocate the node IDs from 0 in 1 increments. The maximum number of nodes on a ring is 16.
      NOTE:
      • For the Local Node ID, enter the MSP node ID of the NE.
      • For the East Node ID and West Node ID, separately enter the east and west MSP node IDs of the node.
      • For the Protocol Type, select the same type for each node in the ring.

    4. Select the mapping direction in the Slot Mapping Settings area, and select an entry from the mapping mode list. Click to associate the mapping direction and the mapping mode.
    5. Click OK. Click Close in the Operation Result dialog box.
  2. Follow 1 to configure other nodes in the ring.
  3. Configure the SDH service on NE1 (source NE).
    1. Select NE1 in the NE Explorer. Choose Configuration > SDH/PDH Service Configuration from the Function Tree.
    2. Click Create in the lower right portion of the window to set required parameters in the Create SDH/PDH Service dialog box that is displayed. Click OK.
