Operation Tasks for Configuring CES Services(OSN 500/550)

This topic describes the operation tasks for configuring CES services in per-NE mode and end-to-end mode on the NMS.

Creating a CES Service in End-to-End Mode

This topic describes how to create CES service channels for transmitting TDM signals in end-to-end mode. You can configure the source node, sink node, and PW attributes of a CES service on a GUI of the NMS, therefore quickly completing the CES service configuration.

Prerequisites

  • You are an NM user with Administrators rights or higher.

  • The CES service port must be configured. The port mode must set to Layer 1. The frame format and frame mode must be set.
  • The MPLS tunnel must be created.

Context

You need to set the frame format for the UNI port that carries the CES service to be the same as the service encapsulation format. If the encapsulation format of the CES service is CESoPSN, you can set the frame format of the UNI port to CRC-4 multiframe (recommended value) or Double frame. If the encapsulation format of the CES service is SAToP, set frame format of the UNI port to unframed.

Procedure

  1. Choose Service > PWE3 Service > Create PWE3 Service from the Main Menu.
  2. Set the parameters on the General Attributes tab page.

    NOTE:
    • You can configure the CES service according to the service template. That is, you can select a service template or create a service template in the Service Template field.
    • Set Service Type to CES.
    • Set Protection Type to Protection-Free.

  3. Select the source and sink NEs of the service.

    NOTE:

    The configuration method is the same for the sink NE, source NE, and transit NE. Therefore, only the example for configuring a source NE is provided as follows.

    1. Click Configure Source And Sink. Then, the Configure Source And Sink dialog box is displayed.
    2. Select a source NE from Physical Topology on the left. Then, the selected NE is displayed in the upper right pane.
    3. All slots and available boards on the NE are displayed. Select the appropriate board according to the service type.
    4. In SAI Configuration, set Low TimeSlot.
    5. In SAI Configuration, set the SAI attribute of the CES access port. Click Add Node. Then, the added source and sink NEs are displayed at the bottom of the pane. Then, click OK.
  4. Optional: Click Configure Source And Sink and then select Unterminated on the left. Set the LSR ID of the unterminated node and click Add Node. Then, the added unterminated source and sink nodes are displayed at the bottom. Then, click OK.

    NOTE:
    Unterminated: On a network, if the equipment at one end of a service can be managed by the U2000, and the equipment at the other end of the service is from another vendor and cannot be managed by the U2000, select Unterminated to set the LSR ID of the opposite end of the service.

  5. Optional: Click Configure PW Switch Node to add working and protection switching NEs between the source NE and the sink NE.
  6. Set parameters of the source and sink NEs that are displayed in Node List. To view the topology of a configured service, click the Service Topology tab in the upper-right area.
  7. Click the PW tab at lower left to set basic attributes of the PW.



    NOTE:
    • The PW ID can be automatically allocated.
    • Signaling Type can be set to Static automatically or manually.
    • Forward Label and Reverse Label can be allocated automatically and manually.
    • Forward Type and Reverse Type support Static Binding. Forward Tunnel needs to be specified manually.
    • You can also set Forward Tunnel and Reverse Tunnel in Service Topology at upper right. Select the tunnel service between the source NE and the sink NE, select Select Forward Tunnel or Select Reverse Tunnel, and select the tunnel for static binding.

  8. Optional: Click Detail. Then, associated information is displayed in the pane at lower right.
  9. Optional: Click the Advanced PW Attribute tab and set the parameters associated with the PW.

    NOTE:
    • The packet loading time needs to be set to the same value for the NEs at both ends.
    • The jitter compensation buffering time needs to be more than two times of the packet loading time.

  10. Select Deploy and then click OK.

    NOTE:
    • In this case, If you select Enable, the service configuration is saved on the NMS and deployed to the NEs. If you deselect Deploy, the service configured is saved only on the NMS but not deployed to NEs. By default, Deploy is selected.
    • When Deploy and Enable are selected, the NE-side tunnel is available only after the tunnel is enabled.

Subsequent Operation

After the service is created successfully, the service is displayed in the PWE3 service management window.

Creating UNI-UNI CES Services on a Per-NE Basis

When creating a CES service on a per-NE basis, you need to set associated service attributes for the source node and the sink node separately.

Prerequisites

  • You are an NM user with Administrators rights or higher.

  • The CES ports must be configured correctly.

Procedure

  1. In the NE Explorer, select an NE, and then choose Configuration > Packet Configuration > CES Service Configuration from the Function Tree.
  2. Click New. Set the CES service parameters in the Create CES Service dialog box that is displayed.
  3. After the setting, click OK.

Creating UNI-NNI CES Services on a Per-NE Basis

If you create a CES service on a per-NE basis, you need to create relevant attributes of the service separately on the source and sink nodes of the service. After the CES service is created, the corresponding PW is automatically created.

Prerequisites

  • You are an NM user with Administrators rights or higher.

  • The CES port must be configured. The port mode must set to Layer 1. The frame format must be set if the CES port is a PDH port.
  • The MPLS tunnel must be created.

Procedure

  1. In the NE Explorer, select an NE, and then choose Configuration > Packet Configuration > CES Service Configuration from the Function Tree.
  2. Click New. Set the CES service parameters in the Create CES Service dialog box that is displayed.
  3. Click Configure PW. Set the PW parameters in the Create PW dialog box that is displayed.
  4. Click the Basic Attributes tab and set the PW parameters of the CES service.

    NOTE:
    • Set PW Signaling Type to Static.
    • Set the other parameters according to the network planning information.

  5. Click the Advanced Attributes tab and set the advanced attributes of the CES service.

    NOTE:
    • The packet loading time needs to be set to the same value for the NEs at both ends.
    • The jitter compensation buffering time needs to be more than two times of the packet loading time.

  6. After setting the parameters, click OK.
  7. Click OK in the Create CES Service dialog box that is displayed.
  8. Navigate to the NE Explorer of the opposite NE and configure the reverse service according to Step 1 to Step 9.
