Abstract
A system for alternately transmitting an audio signal and a video signal over a single voice grade telephone line is disclosed. The system includes an apparatus located at a subscriber location which establishes a first communication connection between a user at the subscriber location and a dispatcher at a dispatch station, over which first communication connection transmission of voice signals are enabled to be simultaneously transmitted between the subscriber's premise and the dispatcher, and which disestablishes the first communication connection and establishes a second communication connection over which a continuous video signal is transmitted from the subscriber location to the dispatcher.

A method of alternately transmitting a voice signal and a continuous video signal over a single voice grade telephone line comprising the steps of:
- establishing a first voice alarm communication connection between a user at a subscriber location and a dispatcher at a dispatch station wherein transmission of voice signals are enabled to be simultaneously transmitted over the single telephone line between the user at the subscriber location and the dispatcher;
- disestablishing the first voice alarm communication connection and establishing a second video alarm communication connection wherein a continuous video signal is enabled to be transmitted from the subscriber location to the dispatcher over the single telephone line;
- and wherein the step of disestablishing the second video alarm communication connection and establishing a third voice alarm communication connection between the subscriber at the subscriber location and the dispatcher, wherein in the third voice alarm communication connection, transmission of voice signals are enabled to be simultaneously transmitted over the single telephone line between the subscriber at the subscriber location and the dispatcher.
