Abstract:
1. A system for adapting an analog system to communicate over a packet network, said system comprising: a security monitoring facility in communication with a packet network; an electronic signal adapter in communication with an analog security system and the packet network, said electronic signal adapter operable to convert information received in a first set of data packets from the security monitoring facility over the packet network into dual-tone multiple frequency (DTMF) signals and single tone analog signals having a signal strength below −25 dBm and durations of less than 150 ms, the electronic signal adapter configured to communicate the DTMF and single tone analog signals to the analog security system; wherein said electronic signal adapter is further configured to convert single tones having the signal strength below −25 dBm and durations of less than 150 ms received from the analog security system into a second set of data packets and transmit the second set of data packets over the packet network using a voice transmission path, and wherein the electronic signal adapter is further configured to mark each frequency in the second set of data packets with a different header to identify a single tone; and an IP telephone coupled to the electronic signal adapter, said IP telephone configured to be utilized by the security monitoring facility during an alarm situation to communicate with a user.
