Configuring Services on the Non-Protection Ring

Configuring Services on the Non-Protection Ring

Configure the protection subnet and the services on the non-protection ring separately. It is recommended that you configure the protection subnet before configuring services on the non-protection ring.

Networking Diagram

You can configure a non-protection ring if the services on the ring need not be protected. In this case, all the timeslots on the ring can carry services.

Figure 2-3 shows a non-protection ring consisting of four pieces of equipment. In this example, the SP3D boards are used on the source NE (NE1) and the sink NE (NE3) as tributary boards to add and drop services, and the SL1D boards are used as line boards to transmit SDH services.

NOTE:

This topic considers the OptiX OSN 550 as an example to describe the board layout. In the case of other products, the configuration method is the same, except for the slots. For the slot information, see the Hardware Description of the relevant product.

Signal Flow and Timeslot Allocation

To configure services on the non-protection ring, you need to plan the traffic direction and timeslot allocation for the services on the non-protection ring.

Figure 2-4 shows the signal flow and timeslot allocation. In this example, five E1 services are added to or dropped from NE1 and NE3, and they pass through NE2.

Per-NE Configuration Process

The configuration of the services on the non-protection ring is not related to the configuration of the protection subnet. To configure the services on the non-protection ring, configure the SDH services from the tributary board to the line board on the source and sink NEs and the pass-through services on the intermediate NEs if the protection subnet is already created.

Prerequisites

  • The physical topology of the network must be created.
  • The NEs, boards, and fibers must be created on the U2000.
  • The created protection subnet must be consistent with the actual network topology. For details about how to create the protection subnet, see Configuring a Non-Protection Ring.
  • You must be familiar with the information about Signal Flow and Timeslot Allocation.

Procedure

  1. Configure SDH services of the source NE (NE1).
    1. Select NE1 in the NE Explorer, and then choose Configuration > SDH Service Configuration from the Function Tree.
    2. Click Create on the lower-right pane to display the Create SDH Service dialog box. Set the parameters that are required, and then click OK.

      Parameter Value in This Example Description
      Level VC12 In this example, E1 services are configured. Hence, Level of the E1 services is set to VC12.
      Direction Bidirectional In this example, the services are transmitted and received over the same path. That is, the services are Bidirectional services.
      Source Slot 3-SP3D In this example, the SP3D board in slot 3 of NE1 is configured as the source tributary board. See Figure 2-4.
      Source VC4 - -
      Source Timeslot Range(e.g.1,3-6) 1-5 In this example, five E1 services are configured between NE1 and NE3. Hence, the service source occupies VC-12s 1-5.
      Sink Slot 1-SL1D-1(SDH-1) In this example, the SL1D board in slot 1 of NE1 is configured as the sink line board. See Figure 2-4.
      Sink VC4 VC4-1 The timeslots where the service sink is located belong to the first VC-4 (VC4-1).
      Sink Timeslot Range(e.g.1,3-6) 1-5 In this example, five E1 services are configured between NE1 and NE2. Hence, the service sink occupies VC-12s 1-5.
      Activate Immediately Yes -

  2. Configure SDH services on the sink NE (NE3). Refer to 1. Set the parameters as follows.

    Parameter Value in This Example Description
    Level VC12 In this example, E1 services are configured. Hence, Level of the E1 services is set to VC12.
    Direction Bidirectional In this example, the services are transmitted and received over the same path. That is, the services are Bidirectional services.
    Source Slot 3-SP3D In this example, the SP3D board in slot 3 of NE3 is configured as the source tributary board. See Figure 2-4.
    Source VC4 - -
    Source Timeslot Range(e.g.1,3-6) 1-5 In this example, five E1 services are configured between NE1 and NE3. Hence, the service source occupies VC-12s 1-5.
    Sink Slot 1-SL1D-2(SDH-2) In this example, the SL1D board in slot 1 of NE2 is configured as the sink line board. See Figure 2-4.
    Sink VC4 VC4-1 The service sink uses the timeslots of VC4-1.
    Sink Timeslot Range(e.g.1,3-6) 1-5 In this example, five E1 services are configured between NE1 and NE3. Hence, the service sink occupies VC-12s 1-5.
    Activate Immediately Yes -

  3. Configure pass-through services on NE2.
    1. Select NE2 in the NE Explorer, and then choose Configuration > SDH Service Configuration from the Function Tree.
    2. Click Create on the lower-right pane to display the Create SDH Service dialog box. Set the parameters that are required, and then click OK.

      Parameter Value in This Example Description
      Level VC12 In this example, E1 services are configured. Hence, Level of the E1 services is set to VC12.
      Direction Bidirectional In this example, the services are transmitted and received over the same path. That is, the services are Bidirectional services.
      Source Slot 1-SL1D-2(SDH-2) In this example, the SL1D board in slot 1 of NE2 is configured as the source line board. See Figure 2-4.
      Source VC4 VC4-1 The timeslots where the service source is located belong to the first VC-4 (VC4-1).
      Source Timeslot Range(e.g.1,3-6) 1-5 In this example, five E1 services are configured between NE1 and NE3. Hence, the service source occupies VC-12s 1-5.

      Activate Immediately Yes -

  4. Check whether the services are configured correctly. For details, see Verifying the Correctness of the SDH Service Configuration.
  5. Enable the performance monitoring function of the NEs. For details, see Setting Network-Wide Performance Monitoring.
  6. Back up the configuration data of the NEs. For details, see Backing Up the NE Data to the System Control Board.
Relevant Task

If the services are configured incorrectly and need to be deleted, see Deleting SDH Services.

End-to-End Configuration Process

The configuration of the services on the non-protection ring is not related to the configuration of the protection subnet. To configure the services on the non-protection ring, configure the SDH services from the tributary board to the line board on the source and sink NEs and the pass-through services on the intermediate NEs if the protection subnet is already created.

Prerequisites

  • The physical network topology must be set up.
  • The NEs, boards, and fibers must be successfully created on the U2000.
  • The protection subnet must be created and must be the same as the actual topology. For details about how to create the protection subnet, see Configuring a Non-Protection Ring.
  • The operator must understand the information provided in Signal Flow and Timeslot Allocation.
