ABSTRACT:
A method and device for detecting errors in a digital time switch that does not require the signal to be synchronous throughout a multi-plane processing unit in a digital time switch. The present invention allows for the detection and localization of errors occurring in one section of one plane in a multi-plane unit. The invention is preferably included in a telecommunications system operating with pulse code modulation and time multiplex. In a multi-plane portion of a digital time switch, there is generated for each one of corresponding parallel planes at corresponding locations a compressed version of the data signal and the corresponding compressed data signals are compared. An alarm is given when the comparison shows a difference between the compressed signals.
