1. Apparatus for detecting an asynchronous event in a communication system and signaling occurrence of said event by transmitting a message to a predetermined device, comprising:

  • an input device for sampling at least one input signal location of said communication system for the occurrence of said event;

    a message transmitter for creating and transmitting said message to said predetermined device for each said occurrence of said event; and

    an event detector connected to said input device and said message transmitter for (i) delaying activation of said message transmitter for a first predetermined time period in order to ensure validity of the occurrence of said event at said input device, and (ii) causing said message transmitter to re-transmit said message in the event said event persists at said input device after a second predetermined time period has elapsed following said transmitting of said message.
