ABSTRACT:
A method and system of monitoring a premises includes testing a digital data link between a Signal Point and a monitored premises, generating an interruption signal to identify any interruption in the data link, generating and transmitting a trouble signal from a processor at the SP to a central monitoring center in response to the interruption signal and then sending a restoration signal from the processor means to said monitoring center when the data link has been restored. The data link means may be part of an ISDN or SS7 network, and the restoration signal may be generated in response to the monitored premises signing-on to the Signal Point.
