Zusammenfassung:Techniques for sending and receiving alarm signals over packet-based communication networks are provided. A system for detecting alarm signals on a multiplexed communication line and generating data packets with alarm information is provided. Additionally, a system is provided for receiving data packets with alarm information and generating alarm signals based upon the alarm information of the data packets. The system optionally monitors a connection to a communication network and the status of one or more nodes coupled with the communication network and generates data packets or alarm signals if predetermined conditions are detected.
