Configuring Line Attributes for a CPOS Interface

Configuring Line Attributes for a CPOS Interface

Context

SDH and SONET are different standards defined by different organizations, but their content and functions are similar. SDH is mainly used in Europe and China and SONET is mainly used in North America and Japan. Different device manufacturers provide different default configurations for them.

You need to configure line attributes for a CPOS interface based on the local standard.

Procedure

  • Perform the following configurations if SDH is used locally:
    1. Run system-view

      The system view is displayed.

    2. Run controller cpos cpos-number

      The specified CPOS interface view is displayed.

    3. Run frame-format sdh

      The frame format is set to SDH for the CPOS interface.

      By default, the frame format of a CPOS interface is SDH.

    4. Run multiplex mode { au-4 | au-3 }

      The AUG multiplexing mode is configured for the CPOS interface.

      By default, the AUG multiplexing mode of a CPOS interface is AU-4.

      NOTE:

      Choose the proper AUG multiplexing mode.

    5. Run clock { master | slave | system }

      The clock mode is configured for the CPOS interface.

      By default, the clock mode of a CPOS interface is slave.

      NOTE:

      When connecting to a SONET/SDH device, a CPOS interface must be configured with the slave clock mode because the clock on a SONET/SDH network is more accurate than the internal clock source on a CPOS interface.

  • Perform the following configurations if SONET is used locally:
    1. Run system-view

      The system view is displayed.

    2. Run controller cpos cpos-number

      The specified CPOS interface view is displayed.

    3. Run frame-format sonet

      The frame format is set to SONET for the CPOS interface.

      By default, the frame format of a CPOS interface is SDH.

    4. Run clock { master | slave | system }

      The clock mode is configured for the CPOS interface.

      By default, the clock mode of a CPOS interface is slave.

      NOTE:

      When connecting to a SONET/SDH device, a CPOS interface must be configured with the slave clock mode because the clock on a SONET/SDH network is more accurate than the internal clock source on a CPOS interface.
