Abstract (en)
[origin: WO0163825A2] A monitoring system for monitoring network stations or nodes for typical alert or maintenance situations, such as outages, in a digital communications network, such as a T1 circuit. A bridge can obtain performance and quality information about the nodes via a passive connection that taps into the digital communications network. A predetermined characteristic analyzer can collect performance and/or quality information output by the bridge. In response to this collected information, the predetermined characteristic analyzer can compare predetermined conditions to a threshold. In the event that the collected information exceeds or deviates from a threshold for a predetermined condition, the predetermined characteristic analyzer generates a trigger that represents a reportable event. This trigger is typically reported to a processor which, in turn, can automatically alert an individual or central monitoring station by forwarding a message regarding the reportable event via an alternate communications path, i.e., a communications path that is not a component of the existing communications network. A wireless transceiver can accept the reportable event message from the processor and transmit that message via the alternate communications path to the network management system. Significantly, this alternative communications path is not competitive with the capacity of the communications network being monitored by the network management system.
