METHOD FOR MONITORING AND/OR CORRECTING SIGNAL QUALITY IN A BRANCHED BIDIRECTIONAL TELECOMMUNICATIONS NETWORK, AND RELATED SYSTEM, COMMAND AND EVALUATION UNIT AND CORRECTIVE AND MEASURING UNIT.

摘要

A method is disclosed for monitoring and/or correcting signal quality in a branched bidirectional telecommunications network comprising a number of network links and stations, which method comprises the following steps (a) and (b): (a) individually monitoring of the signal transmission performance of a number of different signal paths in the network, by(1) providing a test signal on a first position in the network system in a signal path from the first position in the network system to a second position in the network system, (2) measuring a signal quality parameter value at the second position, and(3) evaluating the measured value of the signal quality parameter, (b) correcting a signal transmission performance parameter of one or more of the monitored signal paths in the network, wherein at least one of the steps (a) and (b) comprises the switching and/or adjusting components in one of the monitored signal paths, automatically controlled from a remote position. The steps (a) and (b) are precededby the step of detecting a failure in the regular signal transmission of the network. The signal quality parameter value may represent a signal property derived from other information than digital information encoded in the signal. Also disclosed are a network system, and a correction- and measuring unit.
