Abstract

The present disclosure provides a system and method for providing DSL services and selected telephone service over a common telephone line. Digits or the called numbers are received and if the called numbers correspond to an escape code, the call is enabled. A selected announcement to the calling number may be made if the call is not enabled.

Claims

1. A computer readable medium accessible to a processor for executing instructions contained in a computer program embedded in the computer readable medium, the computer program comprising:

instructions to monitor a trigger associated with a telephone line linked to a Digital Subscriber Line (DSL) service;

instructions to determine digits for a call associated with the telephone line; and

instructions to enable the call to proceed if the determined digits meet a selected criterion.

2. The computer readable medium of claim 1, wherein the selected criterion is an escape code that is one of i) an emergency services access number, ii) a government services access number, and iii) a help line number.

3. The computer readable medium of claim 1, wherein the trigger is one of i) an off-hook delay trigger, and ii) a termination attempt trigger.

4. The computer readable medium of claim 1, wherein the computer program further comprises instructions to send an announcement over the telephone line in response to one of:

an off-hook delay trigger; and

a termination trigger attempt.

5. The computer readable medium of claim 1, wherein the computer program further comprises instructions to query a Service Control Point (SCP) when the determined digits do not meet the selected criterion.

6. The computer readable medium of claim 5, wherein the computer program further comprises instructions to process a response received from the SCP.

7. The computer readable medium of claim 1, wherein the computer program further comprises instructions to receive an input for routing a call associated with the determined digits to a selected location.

8. A system for delivering a Digital Subscriber Line (DSL) service to customer premises comprising:

a telephone line linked to the DSL service;

a database that stores an escape code;

a service switching point (SSP) linked to the database for monitoring presence of the escape code in response to a detected trigger; and

a server having access to a computer program, the server utilizing the computer program to complete a telephone call associated with the telephone line if the telephone call corresponds to the escape code.

9. The system of claim 8, wherein the telephone service is a Plain Old Telephone Service (POTS) from a Central Office to a Customer Premises location.

10. The system of claim 8 further comprising a DSL modem coupled to an end of the telephone line with a current terminator.

11. The system of claim 8, wherein the computer program includes instructions to provide an announcement to a calling party initiating the telephone call.

12. The system of claim 8, wherein the escape code is associated with one of the group consisting of:

i) emergency services;

ii) a customer help;

iii) a government services.

13. The system of claim 8, wherein the trigger is one of:

i) an off-hook delay trigger and ii) a termination attempt trigger.

14. The system of claim 8, wherein the computer program further comprises an AIN service logic instruction.

15. The system of claim 8, wherein the server routes the call to a selected location based on instructions from a Service Control Point.

16. A method for processing a telephone call over telephone linked to a Digital Subscriber Line service, comprising:

monitoring a trigger associated with the telephone line;

determining digits for a telephone call associated with the telephone service; and

enabling the call to proceed if the determined digits meet a selected criterion.

17. The method of claim 16, wherein the selected criterion is an escape code that is one of i) an emergency services access number, ii) a government services access number, and iii) a help line number.

18. The method of claim 16, wherein the trigger is one of i) an off-hook delay trigger, and ii) a termination attempt trigger.

19. The method of claim 16 further comprising sending an announcement to a party making the call in response to one of:

an off-hook delay trigger, and a termination attempt trigger.

20. The method of claim 16 further comprising routing the call to a selected location if the determined digits do not meet the selected criterion.

21. The method of claim 16 further comprising sending a query to obtain instruction for an action if the determined digits do not meet the selected criterion;

and taking the action.
