Abstract
A communication path integrity supervision system is provided in a network system that allows communication of automatic alarm data. This involves a network, needless to say, in which a plurality of automatic alarm data transmitters are linked by diverse paths with at at least one central receiver on the network for receiving the automatic alarm data. In this integrity supervision system, the responsibility for carrying out the integrity supervision functions have been largely shifted onto the remote transmitters--each responsible for its own path or paths--and shifted away from the central receiver to the extent required by the prior art 'receiver-polling' protocol. That is, each transmitter includes circuits for generating and sending to the central receiver a succession of 'next promised check-in' messages, to be on schedule as promised. The central receiver responds to the reception of each such message by updating a table of such messages, scheduling or rescheduling the promised occurrence for the next check-in message as applicable to that particular remote transmitter. The central receiver is further configured with an alert signal for signaling whenever any remote transmitter fails to meet its scheduled or rescheduled next promised check-in. Given the foregoing, the integrity of the communication paths are supervised.
