Configuring the PCM Companding Algorithm

Configuring the PCM Companding Algorithm

Context

There are two pulse code modulation (PCM) companding algorithms: A-law algorithm and u-law algorithm. The A-law algorithm is mainly used in digital communication systems of Europe and China. The u-law algorithm is mainly used in digital communication systems of North America and Japan.

Choose the PCM companding algorithm based on the standard used locally.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface serial interface-number

    The E&M interface view is displayed.

  3. Run em pcm { a-law | u-law }

    The PCM companding algorithm is configured.

    By default, the PCM companding algorithm is A-law algorithm.
