Abstract

Methods and apparatus are disclosed to self-configure a flexible residential gateway providing access to an external communications network, and providing communications with an in home network. An example flexible residential gateway may include at least one voice over Internet protocol (IP) (VoIP) processor, at least one VoIP coupler connecting VoIP signals between at least one VoIP processor and at least one telephone line. In such an arrangement, the VoIP coupler may be configurably capable to disconnect a battery feed voltage and ring voltages from a telephone line. The gateway may further include a switch controller capable of disconnecting the battery feed voltage and the ring voltages from at least one telephone line if POTS signals are detected on at least one telephone line.

3. A flexible residential gateway apparatus as defined in claim 2 further comprising at least one POTS sensor capable to detect the presence of POTS signals on at least one telephone line, and wherein the switch controller uses at least one POTS sensor output to determine whether to disconnect the battery feed voltage and the ring voltages from at least one telephone line.

4. A flexible residential gateway apparatus as defined in claim 3 wherein a respective VoIP coupler, a respective configurable battery switch, and a respective POTS sensor are associated with each telephone line.

5. A flexible residential gateway apparatus as defined in claim 4 wherein the switch controller controls the configurable battery switch of a first VoIP coupler associated with a first telephone line to disconnect the battery feed voltage and the ring voltages from the first telephone line if POTS signals are detected on the first telephone line.

6. A flexible residential gateway apparatus as defined in claim 3 wherein POTS signals comprise at least one of battery feed voltage or sealing current.

7. A flexible residential gateway apparatus as defined in claim 1 wherein the flexible residential gateway is expanded using at least one additional VoIP processor, at least one additional VoIP coupler, and at least one additional telephone line implemented in at least one expansion unit attached to the flexible residential gateway via at least one communications cable or connector.

8. A flexible residential gateway apparatus as defined in claim 1 further comprising:

at least one configurable switch to disconnect the HomePNA processor from at least one telephone line; and

one VDSL sensor to detect the presence of VDSL signals on a first telephone line that communicates xDSL signals with the connected external network;

wherein the switch controller controls at least one configurable switch to disconnect the HomePNA processor from all telephone lines if VDSL signals that interfere with the HomePNA signals are present on the first telephone line that communicates xDSL signals with the connected external network.

9. A flexible residential gateway apparatus as defined in claim 1

wherein a respective VoIP coupler and a respective POTS sensor are associated with each telephone line, and

wherein the switch controller controls a first VoIP coupler associated with a first telephone line to disconnect the battery feed voltage and the ring voltages from the first telephone line if POTS signals are detected by the first POTS sensor on the first telephone line.

10. For a flexible residential gateway providing access to an external communications network, and providing voice over Internet protocol (IP) (VoIP) communications between at least one VoIP processor and an in home network through at least one telephone line, the flexible residential gateway providing a battery feed voltage and ring voltages to the at least one telephone line if a VoIP signal is present, a self-configuration method comprising:

detecting the presence of plain old telephone service (POTS) signals on at least one telephone line;

disconnecting the battery feed voltage and ring voltages from at least one telephone line if POTS signals are detected on at least one telephone line, the battery feed voltage and the ring voltages provided to support telephone operation;

detecting the presence of VDSL (Very high speed Digital Subscriber Line) signals on at least one telephone line, and disconnecting a HomePNA processor from at least one telephone line if VDSL signals that interfere with HomePNA communications are detected on at least one telephone line.

11. A self-configuration method as defined in claim 10 wherein disconnecting a battery feed voltage and ring voltages from at least one telephone line uses at least one configurable battery switch.

12. A self-configuration method as defined in claim 10 wherein detecting the presence of POTS signals uses at least one POTS sensor to detect the presence of POTS signals on at least one telephone line.

13. A self-configuration method as defined in claim 12 wherein a respective POTS sensor is associated with each telephone line, and wherein the battery feed voltage and the ring voltages are disconnected from a first telephone line if POTS signals are detected on the first telephone line.
