Abstract

A method and apparatus for acquiring and analysing PCM data in a communications system. The method comprises extracting a PCM data of a selected circuit from PCM streams (30), sampling the PCM data for one or more predetermined periods and storing them in PC memory (14), converting the stored data from PCM format to a non-compressed format suitable for analysis, display or comparison. The method allows for a simple PC based monitoring of PCM data in a communications system.
