NON-INVASIVE REMOTE MONITORING AND REPORTING OF DIGITAL COMMUNICATIONS SYSTEMS

摘要

A kind of monitoring system, for monitoring network station or node for the typical alarm such as shutdown or maintenance condition, in digital communications network, the circuit of such as T1. A kind of bridge performance and quality information can be obtained about node via that access digital communications network of passive connection. Scheduled analyser can collect performance and/or quality information output passes through the bridge. In response to the information of the collection, scheduled analyser being capable of more scheduled condition and threshold value. If the information collected is more than or deviates the threshold value for predetermined condition, scheduled analyser generates the trigger signal for indicating can to report event. This triggering is normally reported to processor, in this way, can successively alert automatically personal or central monitoring station by will about can report event message via alternate communication path, i.e. the communication path existing communication network that is a not no component. Wireless transceiver can receive reportable event information from processor and transmit this message via alternate communication path to Network Management System. Importantly, this alternative communication path cannot be with the capacity of communication network by Network Management System.
