Abstract

Systems and methods for integrating analog voice service and derived POTS voice service in a DSL environment are provided. One embodiment is a system comprising: a first communication path for carrying plain old telephone service (POTS) voice signals between a telephone-type device and a subscriber line of a telephone network; a second communication path for carrying derived POTS voice signals between the telephone-type device and the subscriber line; and a switching mechanism configured to switch the telephone-type device between the first communication path and the second communication path.

Claims

1. A method comprising the steps of:

monitoring a subscriber loop for signaling associated with a call, the subscriber loop carrying an analog POTS channel and a derived POTS channel;

responsive to subscriber loop signaling on one of the channels, determining whether the call is processed using the analog POTS channel or the derived POTS channel; and

processing the call using one of the channels, according to the determination.

2. The method of claim 1, wherein the determining step further comprises:

receiving a user selection indicating whether the call is processed using the analog POTS channel or the derived POTS channel.

3. The method of claim 1, further comprising:

monitoring the subscriber loop for off-hook signaling from a telephone coupled to the subscriber loop indicating that a call is to be originated;

selecting the analog POTS channel or the derived POTS channel for origination of the call; and

originating the call using the selected channel.

4. The method of claim 1, further comprising:

monitoring the subscriber loop for off-hook signaling from a telephone coupled to the subscriber loop indicating that a call is to be originated;

selecting the analog POTS channel for origination of the call; and

originating the call using the analog POTS channel.

5. The method of claim 1, further comprising:

monitoring the subscriber loop for off-hook signaling from a telephone coupled to the subscriber loop indicating that a call is to be originated;

selecting the derived POTS channel for origination of the call; and

originating the call using the derived POTS channel.

6. The method of claim 1, further comprising:

monitoring the subscriber loop for signaling indicating the presence of an incoming call on one of the channels;

selecting the analog POTS channel or the derived POTS channel for origination of the call; and

answering the call using the selected channel.

7. The method of claim 1, further comprising:

monitoring the subscriber loop for signaling indicating the presence of an incoming call on one of the channels;

selecting the analog POTS channel for answering the call; and

answering the call using the analog POTS channel.

8. The method of claim 1, further comprising:

monitoring the subscriber loop for signaling indicating the presence of an incoming call on one of the channels;

selecting the derived POTS channel for answering the call; and

answering the call using the derived POTS channel.

9. A device comprising:

memory having stored thereon program code; and

a processor that is programmed by at least the program code to enable the system to;

monitor a subscriber loop for signaling associated with a call, the subscriber loop carrying an analog POTS channel and a derived POTS channel;

responsive to subscriber loop signaling on one of the channels, determine whether the call is processed using the analog POTS channel or the derived POTS channel; and

process the call using one of the channels according to the determination.

10. The device of claim 9, wherein the processor is further programmed enable the system to:

monitor, while a first call is active on one of the channels of the subscriber loop, the other channel of the subscriber loop to detect call signaling indicative of a second incoming call on the other channel; and

determine call instructions for the second incoming call; and

process the second incoming call according to the call instructions.

11. The device of claim 9, wherein the processor is further programmed enable the system to:

monitor, while a first call is active on one of the channels of the subscriber loop, the other channel of the subscriber loop to detect call signaling indicative of a second incoming call on the other channel;

responsive to the detected call signaling, place on hold the first call on the one channel and answer the second call on the second channel.

12. The device of claim 9, wherein the processor is further programmed enable the system to:

monitor, while a first call is active on one of the channels of the subscriber loop, the other channel of the subscriber loop to detect call signaling indicative of a second incoming call on the other channel; and

conference the first call on the one channel with the second call on the second channel.

13. The device of claim 9, wherein the processor is further programmed enable the system to:

monitor, while a first call is active on one of the channels of the subscriber loop, the other channel of the subscriber loop to detect call signaling indicative of a second incoming call on the other channel; and

provide, responsive to the detected call signaling and while the first call is active, a ring notification signal to a user.

14. The device of claim 9, wherein the processor is further programmed enable the system to:

monitor, while a first call is active on a first one of the channels, the second other one of the channels to detect caller identification signaling, the caller identification signaling including a calling number;

provide, responsive to the detected call signaling and while the first call is active, the calling number to a user.

15. The device of claim 9, wherein the processor is further programmed enable the system to:

monitor, while a first call is active on a first one of the channels, the second other one of the channels to detect call signaling, the call signaling associated with an incoming call, the incoming call associated with a calling number;

responsive to the detected call signaling, drop the incoming call on the second channel; and

originate on the first channel a second call to the calling number when the first call is no longer active.

16. The device of claim 9, wherein the processor is further programmed enable the system to:

monitor, while a first call is active on a first one of the channels, the second other one of the channels to detect call signaling, the call signaling associated with a second incoming call;

while the first call is active, provide an indication of the second incoming call to a user;

upon receiving an indication from the user to switch to the second incoming call, put the first call on hold and switching to the second incoming call.

17. A computer-readable medium having a program comprising the steps of:

monitoring a subscriber loop for signaling associated with a call, the subscriber loop carrying an analog POTS channel and a derived POTS channel;

responsive to subscriber loop signaling on one of the channels, determining whether the call is processed using the analog POTS channel or the derived POTS channel; and

processing the call using one of the channels according to the determination.

18. The computer-readable medium of claim 17, the program further comprising the steps of:

monitoring, while a first call is active on the analog POTS channel of the subscriber loop, the derived POTS channel of the subscriber loop to detect call signaling indicative of a second incoming call on the derived POTS channel; and

responsive to the detected call signaling, forwarding the second call on the derived POTS channel to voicemail.

19. The computer-readable medium of claim 17, the program further comprising the steps of:

monitoring, while a first call is active on the derived POTS channel of the subscriber loop, the analog POTS channel of the subscriber loop to detect call signaling indicative of a second incoming call on the analog POTS channel; and
