Abstract

System for monitoring the performance of at least one line at a node of a digital communication network, such a system including a set of hardware registers associated with the line for registering line performance information associated therewith, a set of counters associated with the line, each counter defining a parameter depending on the line performance information, and a processing unit for, during a predetermined period of time, gathering the line performance information from the counters in a performance report to be sent to a network management unit. One table (22, 24 or 26) is associated with the line and stores all the data necessary to read the parameter for each counter of the associated set of counters with the line, and a processing machine (20) reads the table, sequentially computes the parameters defined by each counter by using the data stored in the table, and sequentially updates the counters.
