Creating an XPIC Working Group

When two IF boards that form an XPIC working group are installed on an IDU, you can create an XPIC working group to ensure that the XPIC working group is configured with the same work mode, transmission frequency, TX power, and ATPC attributes.

Prerequisites

  • The IF boards and the ODUs to which the IF boards are connected must be created.

  • The XPIC Enabled parameter must be set to Enabled for the IF boards.

Context

In the NE Explorer, choose Configuration > Link Configuration from the navigation tree. Click the XPIC tab.

  • Relationship with the 1+1 Protection Configuration: The two IF boards in an XPIC working group cannot be configured into one 1+1 protection group, but the two IF boards in different XPIC working groups can be configured into one 1+1 protection group. Therefore, the four IF boards in two XPIC working groups can form two 1+1 protection groups.
  • Relationship with N+1 protection: Each member of an XPIC working group can work as the working channel or the protection channel of the N+1 protection.
  • Relationship with the ATPC feature: The transmit power of the two ODUs that are in an XPIC working group should be the same if possible. Hence, each of the ATPC parameters should be set to the same value for the IF boards that are in an XPIC working group.
NOTICE:

Deleting XPIC working groups may interrupt services. Exercise caution when you perform this operation.

Procedure

  1. In the Main Topology, right-click a microwave link and choose HOP Management from the shortcut menu.
  2. Choose Configuration > Link Configuration from the navigation tree.

  3. Click New for the NE at one end and set XPIC group parameters.

    NOTE:
    • When CCDP is applied to the STM-1 microwave links, the IFX/IFX2 boards must be installed and the XPIC function must be enabled.
    • An XPIC working group must be configured to ensure that the XPIC working group is configured with the same working mode, transmission frequency, transmit power, and ATPC attributes.
    • When the used ODUs support two T/R spacings, ensure that the two ODUs of an XPIC working group adopt the same T/R spacing.

  4. Click Apply.
  5. Optional: Repeat steps 3 to 4 for the NE at the other end.
  6. Click OK.

Follow-up Procedure

Generally, you do not need to configure the IF/ODU information after you configure an XPIC working group. You, however, need to set the T/R spacing used by the ODU on the IF/ODU Configuration tab page if the used ODU supports two T/R spacings.
