An apparatus for monitoring a telecommunications system includes a detachable communications module, such as a modem, connected to a call line that is independent of the system to be monitored. A controller is connected to the monitored system and to the communications module. The controller includes at least one detector for sensing various off-normal conditions relevant to operating the monitored system. The controller also includes an auto-dialer that is responsive to the detectors for triggering a call to a remote site via the telecommunications module upon sensing the presence of one of the off-normal conditions. A backup power source is connected to power the controller and the communications module if a primary power source fails. Preferably, the backup source includes at least one battery and the backup source, the controller, and the communications module are contained in a housing that is separate from the monitored system. Inputs to the preferred self-contained unit include a cable from a telecommunications switch (e.g., CBX) and ancillary inputs from equipment such as servers and alarm equipment. A service port is included to allow on-site diagnostic servicing and reprogramming of either or both of the monitored system and the monitoring unit. Non-volatile memory is included and can be upgraded locally using the service port or remotely using the communications module. Because the communications module is detachable, the module can be upgraded as desired, without affecting the implementation of the controller logic and circuitry.
