Abstract

This invention regards an integrated access device (10) and a method therefore, comprising seamless PSTN to voice over Internet telephony. The access device (10) thus comprises a splitter (12, 32) having a filter filtering out data traffic from a digital subscriber line to the access device (10), allowing PSTN signals to pass through. It further comprises at least two ports (28) for connection of two telephone devices (38, 40), wiring the pair of wires (22) from one of the telephone ports to a pair of PSTN wires of a LAN port (26) receiving incoming PSTN and DSL signals, thus providing exclusion of rewiring in an external splitter (12) and that one of the telephone ports can be utilized booth for Internet voice and PSTN telephony.

Claims

1. An integrated access device performing seamless public switched telephone network to voice over Internet telephony, characterized by comprising:

a splitter having a filter filtering out data traffic from a digital subscriber line to said access device, allowing public switched telephone network signals to pass through; and

at least two telephone ports for connection of voice over Internet telephony devices, wiring a pair of wires from one of said telephone ports to a pair of public switched telephone network wires of a network port receiving incoming public switched telephone network and DSL signals, thus providing that one of said telephone ports and said network port (26) can be utilized for connecting public switched telephone network telephony.

2. An access device according to claim 1, characterized in that a switch is connected to said filter device and said switch splitting said wiring from one of said pair of public switched telephone network wires for switching said filtered public switched telephone network signals from said filter to a telephone line for voice over Internet telephony.

3. An access device according to claim 2, characterized in that said switch is set to switch between one of said ports, thereby directing public switched telephony to said port by setting a software parameter, said parameter controlling the electronics utilized for switching.

4. An access device according to claim 1, characterized in that a signal on the pair of public switched telephone network wires is fed via said splitter to one of said telephones.

5. An access device according to claim 1, characterized in that a signal on the pair of public switched telephone network wires is fed to the voice over Internet circuit on one of said telephones.

6. An access device according to claim 2, characterized in that it provides through said switch (34) that one of said telephone ports can be utilized both for voice over Internet and public switched telephone network telephony.

7. An access device according to claim 6, characterized in that said switch is set to switch between public switched telephone network and voice over the Internet by setting a software parameter, said parameter controlling the electronics utilized for switching.

8. An access device according to claim 6, characterized in that said switch is controlled by voltage on the public switched telephone network line or absence of voltage.

9. A method in an integrated access device performing seamless public switched telephone network to voice over Internet telephony, characterized by comprising the steps of:

from a splitter having a filter filtering out data traffic from a digital subscriber line to said access device, allowing public switched telephone network signals to pass through; and

said access device having at least two telephone ports for connection of voice over Internet telephony devices, wiring a pair of wires from one of said telephone ports to a pair of public switched telephone network wires of a network port receiving incoming public switched telephone network and DSL signals, thus providing that one of said telephone ports and said network port can be utilized for connecting public switched telephone network telephony.

10. A method in an access device according to claim 9, characterized in connecting a switch to said filter device and said switch splitting said wiring from one of said pair of public switched telephone network wires for switching said filtered public switched telephone network signals from said filter to a telephone line for voice over Internet telephony.

11. A method in an access device according to claim 10, characterized in that said switch is set to switch between one of said ports, thereby directing public switched telephony to said port by setting a software parameter, said parameter controlling the electronics utilized for switching.

12. A method in an access device according to claim 9, characterized in that a signal on the pair of public switched telephone network wires is fed via said splitter to one of said telephones.

13. A method in an access device according to claim 9, characterized in that a signal on the pair of public switched telephone network wires is fed to the voice over Internet circuit on one of said telephones.

14. A method in an access device according to claim 10, characterized in that it provides through said switch that one of said telephone ports can be utilized both for voice over Internet and public switched telephone network telephony.

15. A method in an access device according to claim 14, characterized in that said switch is set to switch between public switched telephone network and voice over the Internet by setting a software parameter, said parameter controlling the electronics utilized for switching.

16. A method in an access device according to claim 14, characterized in that said switch is controlled by voltage on the public switched telephone network line or absence of voltage.
