Abstract

Abstract The invention relates to a system for monitoring and managing a point-to-multipoint access network to connect a line terminal (10 1 ) to a plurality of network terminations (30). Each network termination (30) comprises facilities (31) for detecting transmission errors. For each error that is so detected, facilities (31) generate a word (m) which is representative of the detected error. Processing facilities (33) are provided in order to process the words generated by the detection facilities (31). In each network termination (30), there are simulation facilities (38) for generating simulated error words (ms) and facilities (32) for replacing for the errors which are detected by the detection facilities and by the simulated error words (ms) generated by the said simulation facilities. The point is to provide known signals which can be monitored in order to test the accuracy of the equipment.
