Interoperability of Legacy Alarm System
First Claim
Patent Images
1. A base station for supporting communications over a VoIP network, including communications used to support cordless phone calls, analog phone calls, and transmission of an alarm message from a legacy alarm system, the base station comprising:
- a housing having an output port for exchange signals with the VoIP network and at least one input port for exchanging signals with a cordless phone handset, an analog line, and the legacy alarm system;
a cordless phone transceiver within the housing, the cordless phone transceiver configured to exchange digital signaling with the cordless phone handset in order to support a cordless phone call;
an analog line adaptor within the housing, the analog line adaptor configured to convert analog signaling used to support an analog phone call over a plain old telephone system (POTS) phone line into digital signaling; and
a media terminal adaptor (MTA) within the housing, the MTA configured to interface the digital signaling and the alarm messaging from the cordless phone transceiver and the analog line adaptor with the VoIP network according to a prioritization scheme, the prioritization scheme requiring the MTA to interrupt a phone call supported by the cordless phone transceiver upon determining a need for the legacy alarm system to transmit the alarm message over the VoIP network.

Abstract
A base station and system configured to support interfacing digital and analog devices with a legacy alarm system in a manner that allows messages from the legacy alarm system to pre-empt other messaging, if needed, when the messaging takes place through the same gateway as that which is used by the legacy alarm system.

7. A base station for interfacing digital and analog telephone calls with a telephony network comprising:
-
an adaptor configured to interface digital and analog telephone signaling used to support digital and analog telephone calls with the telephony network; and a priority controller in communication with the adaptor, the priority controller configured to pre-empt both digital and analog telephone calls in the event a legacy alarm system needs to transmit an alarm message with the use of analog telephone signaling, the legacy alarm system characterized by an inability to seize the digital telephone signaling. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A method of supporting interoperability of a legacy alarm system with a digital telephony network, the legacy alarm system being configured to communicate analog alarm messages upon successful seizure of a POTS telephone line, the POTS telephone line being included at a location protected by the legacy alarm system, the location including a base station configured to interface alarm messages and cordless phone calls with the digital telephony network, the method comprising:
-
automatically detecting an attempt of the legacy alarm system to seize the POTS telephone line as a function of a sensed operating change in the legacy alarm system, the attempt being determined without requiring the legacy alarm system to transmit a message or to otherwise indicate seizure of the POTS telephone line; and in the event a cordless phone call is taking a place at the time the attempt of the legacy alarm system to seize the POTS telephone line is detected and the base station is unable to support both the cordless phone call and transmission of an alarm message, automatically interrupting the cordless phone call in order to permit transmission of the alarm message. - View Dependent Claims (19, 20)
