A method and arrangement for detecting and localizing errors or mistakes in a multi-plane unit incorporated in a digital time switch.

摘要

The present invention relates to a digital time switch provided with equipment at several levels of overlap. THE DIGITAL SWITCH time is included in a telecommunications system operating with a code modulation multiplexer WRIST AND TIME. The invention DESTINED TO SOLVE TECHNICAL PROBLEMS TO DETECT AND LOCATE PRECISELY BUGS OR ERRORS IN A MULTIPLE UNIT PLANS. IN ONE UNIT PLANS MULTIPLES (10) having sections (12) EQUIPMENT (11) in three planes parallel chambers (A, B, C), is generated for each of the sections corresponding parallel (12) at locations A VERSION IS MATCHING compressed data signal (IN) entering the section and / or data signal (OUT) LEAVING THE SECTION. Then compared the corresponding signals compressed data (CO) and triggers an alarm when the comparison shows that there is a difference between data signals TABLETS (CO) being compared.
