Filed:

Dec 18, 1998

Appl. No.:

9/215827

Inventors:

Akhtar Akhteruzzaman - Naperville IL
Ronald Joseph Rees - Bolingbrook IL
Ian Andrew Schorr - Chicago IL

Assignee:

Lucent Technologies Inc. - Murray Hill NJ

International Classification:

H04M 1104

US Classification:

379 45

Abstract:

A method and system for responding to security system inoperability due to damage of a telecommunications line interconnecting the security system to its central monitoring service system requires origination of a wireless telephone call. A wireless unit is interconnected to the security system and originates an emergency call upon detection of telecommunications line abnormalities. Upon establishing a call connection between the wireless unit and the central monitoring service system, the wireless unit relays dual tone multifrequency (DTMF) signals which identify the security system affected by the breach so that appropriate authorities may be dispatched. In alternative embodiments, the wireless unit is programmed to place calls to other designated telephone numbers.

Abstract:

A method and system for providing redundancy for security systems served by the public switched telephone network (PSTN) includes a cable modem interconnected to a security system controller. Upon detection of inoperability of a telecommunications line serving the system via the PSTN, the cable modem extends an alert message to a security monitoring service via a packet data network. Advantageously, the cable modem can also send video images and audio from the secured premises to the security monitoring system due to the bandwidth capabilities of the packet data network.
