Abstract
A communication path integrity supervision system is provided for a network of automatic alarm data transmissions. A plurality of alarm data transmitters are linked by diverse paths with a central receiver for such automatic alarm data, wherein the responsibility for carrying out integrity supervision has 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. Hence each transmitter generates and sends to the central receiver a succession of check-in messages. The central receiver responds to each such message by updating a table of such messages, scheduling or rescheduling the next check-in as applicable to that particular remote transmitter. An alert is signaled whenever any remote transmitter fails to meet its scheduled or rescheduled check-in. Given the foregoing, the integrity of the communication paths are supervised.
