A Bluetooth-wireless docking station for use with a Bluetooth-enabled cellular mobile handset, which docking station allows mobility to the cellular mobile handset rather than having to be fixed stationarily in the docking station, which docking station couples standard POTS telephone sets, or POTS-like telephone units, connected to in-premises wiring, to the cellular, or cellular like, network. The cellular mobile handset may be used to make or receive calls remote from the docking station, while the docking station communicates with the Bluetooth-enabled cellular mobile handset via a Bluetooth-wireless transceiver using Bluetooth-wireless air-interface protocol. A subscriber-line interface circuit, controlled by a microprocessor, couples the standard POTS telephone sets to the cellular mobile handset's transceiver whereby the phones may make or receive calls via the cellular, or cellular like, network, which subscriber line interface also provides loop current, ring signaling, dial tone, loop current detect, flash detection, DTMF conversion, and other central office functions to the telephone sets. As long as the cellular mobile handset is within range of the Bluetooth-wireless transceiver of the docking station, the telephones are connected to the cellular network, as long as the cellular mobile handset is not engaged in a call of its own. The same docking station is capable of accommodating and being paired with any of a wireless-enabled TDMA-based, GSM-based, CDMA-based, or AMPS-based standard transceiver.

When an alarm panel needs to transmit alarm data, it seizes the PSTN and disconnects the premises-wiring. If in a call, the user is cut off immediately and it appears to the user that the connection to the PSTN has been lost. If trying to place a call, the user also perceives that the connection to the PSTN is lost. The present invention provides tonal signals to the user to indicate that the PSTN line is in use by the alarm panel and also notifies the user when the PSTN connection is available for use.

Method and apparatus for improving premises-line call availabiliy in an alarm system

A device for redirecting alarm-messaging from an alarm control panel from its connection to the PSTN to a backup radio transceiver for transmission of the alarm signaling to a central alarm station via a radio network. The switch-over to the radio network occurs not only when the PSTN line is down, for whatever reason, but also occurs when the PSTN line is already occupied by an existing transmission by a premises' telephones, in order to allow the user to make a call over the PSTN during such an alarm condition. Moreover, if during the time the alarm control panel is transmitting its alarm messages over the PSTN, a premises' telephone goes off-hook, the device of the invention terminates the alarm panel's connection to the PSTN and automatically switches over the alarm panel to the radio backup system.
