Abstract
A method and apparatus for communicating between Customer Premises Equipment, (CPE) alarm sensing devices, and alarm monitoring stations. The sensing devices communicate with an end office switch by transmitting a message, such as a string of Dual-Tone Multi-Frequency, (DTMF) digits to that switch. At the switch, the message is processed and a determination is made which of a plurality of alarm monitoring stations should receive the alarm indication. One or more data packets are sent to the selected alarm monitoring stations with the packets identifying the source of the alarm indication, and the type of alarm indication. Advantageously, the packetized communication between the end office switch and the alarm monitoring system allows a high volume of alarm indications to be sent to an alarm monitoring station, because individual telephone connections are not required for each such alarm message.
