Abstract

A communications unit is provided that can be coupled to a building'"'"'s telecommunication wiring to provide an automated mechanism for isolating the building'"'"'s wiring from a PSTN, while also providing a telecommunications connection to an alternative communications network via, for example, broadband or cellular networks. The communications unit can further be configured to be coupled to an alarm controller unit of a security system, thereby permitting the security system to communicate with a remote server system without loss of alarm data. The communications unit can also be configured to permit the legacy security system to provide normal disconnect functionality of building telephones from an outgoing telecommunications line while an alarm condition is present.

Claims

1. An apparatus comprising:

a processor;

a network interface coupled to the processor and configured to receive communication configuration information from a network;

a first interface to a public switched telephone network (PSTN) coupled to a switch configured to be controlled by the processor; and

a second interface to a building telephone wiring coupled to the switch, wherein

the processor is configured to isolate the building telephone wiring from the PSTN by placing the switch in an open state, in response to the communication configuration information.

2. The apparatus of claim 1 further comprising:

an analog telephone adapter (ATA) configured to convert information in analog signals received by the second interface for transmission on the network; and

the network interface is further coupled to the ATA and is further configured to transmit the converted information on the network.

3. The apparatus of claim 1 further comprising:

a cellular interface coupled to the second interface and configured to transmit information provided in analog signals received by the second interface to a cellular network.

4. The apparatus of claim 1, wherein

the apparatus is coupled to a security system, and

the processor is configured to

receive information from the security system,

transmit the information from the security system using a selected one of the network interface, the first interface, and a cellular interface coupled to the processor.

5. The apparatus of claim 4, wherein

the processor is further configured to convert the information received from the security system to a form appropriate for the selected transmission interface.

6. An apparatus comprising:

a first interface to a public switched telephone network (PSTN);

a second interface to a building telephone wiring;

means for receiving communication configuration information from a network; and

means for automatically isolating the building telephone wiring from the PSTN, wherein

said isolating is performed in response to the communication configuration information.

7. The apparatus of claim 6 further comprising:

means for converting information contained in analog signals received by the second interface for transmission to the network; and

means for transmitting the converted signals to the network.

8. The apparatus of claim 6 further comprising:

means for transmitting information contained in analog signals received by the second interface to a cellular network.

9. The apparatus of claim 6 further comprising:

means for receiving information from a security system; and

means for transmitting the information from the security system using one of an interface to the network, the first interface, and a means for transmitting to a cellular network.

10. A method comprising:

receiving communication configuration information; and

automatically isolating telephone wiring of a building from a public switched telephone network (PSTN) in response to the communication configuration information.

11. The method of claim 10 further comprising:

selecting a network for transmission of telecommunication signals;

receiving telecommunication signals from the telephone wiring of the building;

converting the telecommunication signals to a form appropriate for transmission on the selected network; and

transmitting the converted telecommunication signals on the selected network.

12. The method of claim 10 wherein the selected network is a broadband network.

13. The method of claim 12 wherein said converting comprises an analog-to-digital conversion.

14. The method of claim 12 wherein said converting is performed by an analog telephone adapter.

15. The method of claim 10 wherein the selected network is a cellular network.

16. A system comprising:

a communications unit coupled to a building telephone wiring and further coupled to a public switched telephone network (PSTN), wherein

the communication unit is configured to

receive communication configuration information, and

automatically isolate the building telephone wiring from the PSTN in response to the communication configuration information.
