Abstract

A method and system for facilitating voice over broadband communication for use in residences and small businesses is disclosed. A voice signal from an analog telephone is frequency upconverted. The frequency upconverted voice signal is communicated over pre-existing analog telephone wiring. The communicated frequency upconverted voice signal is then frequency downconverted for use by an integrated access device. In this manner, re-wiring of the residence or business is avoided.

Claims

1. An adapter for facilitating use of an analog telephone in voice over broadband communication, the adapter comprising:

a circuit for processing a POTS signal;

a modulator/demodulator circuit; and

a switching circuit configured to route communications between a telephone and home wiring through a selected one of the circuit for processing a POTS signal and the modulator/demodulator circuit.

2. The adapter as recited in claim 1, wherein the circuit for processing a POTS signal comprises a POTS microfilter.

3. The adapter as recited in claim 1, wherein the modulator/demodulator circuit comprises a single sideband modem.

4. The adapter as recited in claim 1, wherein the switching circuit comprises a first switch to which a telephone is connectable and a second switch to which home telephone wiring is connectable.

5. A method for facilitating use of an analog telephone in voice over broadband communication, the method comprising operating a switch so as to effect one of:

processing a POTS signal for communication between a telephone and home wiring; and

modulating/demodulating a signal for communication between a telephone and home wiring.

6. The method as recited in claim 5, wherein modulating/demodulating a signal comprises frequency up conversion of communications from the telephone to home wiring and frequency down conversion of communications from home wiring to the telephone.

7. The method as recited in claim 5, wherein processing a POTS signal comprises microfiltering the POTS signal.

8. The method as recited in claim 5, wherein modulating/demodulating a signal comprises single sideband modulating/demodulating the signal.

9. The method as recited in claim 5, wherein modulating/demodulating a signal comprises modulating/demodulating a signal having a bandwidth of approximately 4 kHz.

10. The method as recited in claim 5, wherein modulating/demodulating a signal comprises modulating/demodulating a signal for a frequency band selected from the group consisting of:

516.3125 kHz to 1104 kHz;

8.625 kHz to 133.6875 kHz;

bins from 1104 kHz downward, as needed; and

2208 kHz. To 5500 kHz.

11. An adapter for facilitating use of an analog telephone in voice over broadband communication, the adapter comprising:

means for facilitating POTS passthrough;

means for modulating and demodulating a signal; and

a switching circuit configure to route communications between a telephone and home wiring through a selected one of the means for facilitating POTS passthrough and the means for modulating and demodulator a signal.

12. An integrated access device comprising:

a multichannel FDM modem;

a digital signal processor; and

wherein the multichannel FDM modem cooperates with the digital signal processor to facilitate the use of an analog telephone in broadband communications using pre-existing home telephone wiring.

13. The integrated access device as recited in claim 12, wherein the multichannel FDM modem comprises a multichannel single sideband modem.

14. The integrated access device as recited in claim 12, wherein the multichannel FDM modem comprises a multichannel single sideband modem that is configured to modulate/demodulate a signal having a bandwidth of approximately 4 kHz
