Abstract

A system that incorporates teachings of the present disclosure may include, for example, receiving, by a first line card coupled to minimally twisted or non-twisted pair cables, a very high digital subscriber line signal, modifying the very high digital subscriber line signal for transmission over the minimally twisted or non-twisted pair cables to generate an updated very high digital subscriber line signal that overcomes a transmission deficiency, and transmitting from the first line card the updated very high digital subscriber line signal to a second line card to cause the second line card to receive the adapted very high digital subscriber line signal at a desired signal quality and convert the updated very high digital subscriber line signal to a very high digital subscriber line signal for presentation of interactive television services at the customer premise equipment. Other embodiments are disclosed.

Claims

1. A method, comprising:

receiving, by a processing system including a processor, a signal via minimally twisted pair cables, wherein the signal comprises a very high digital subscriber line signal;

applying a noise canceling filter, by the processing system, to modify the signal for transmission over the minimally twisted pair cables, to generate an updated signal, wherein the updated signal comprises a very high digital subscriber line signal; and

transmitting, by the processing system, the updated signal to a line card to cause the line card to receive the updated signal wherein the line card converts the updated signal to a converted signal for presentation of interactive television services at customer premise equipment, and wherein the converted signal comprises a very high digital subscriber line signal.

2. The method of claim 1, wherein the applying the noise canceling filter does not include applying a sealing current to the signal.

3. The method of claim 1, wherein the minimally twisted pair cables have a transmission deficiency which prevents reliable delivery of the signal at a desired signal quality for presenting interactive television services at customer premise equipment.

4. The method of claim 3, wherein the applying the noise cancelling filter is configured to overcome the transmission deficiency.

5. The method of claim 1, further comprising applying line correction to the signal before applying the noise canceling filter to the signal.

6. The method of claim 1, further comprising applying, by the processing system, fault isolation to determine a location of a fault between the system and the line card.

7. The method of claim 1, wherein the applying the noise cancelling filter is performed by applying synchronization signals to the signal between the system the line card.

8. The method of claim 1, wherein the applying the noise cancelling filter is performed by applying a sealing current to the signal.

9. A system to transmit and receive interactive television services using a minimally twisted pair cables, comprising:

a processing system including a processor; and

a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, comprising;

receiving a signal; and

modifying the signal for transmission over the minimally twisted pair cable to a line card as a modified signal, wherein the line card converts the modified signal to a converted signal enabling customer premise equipment associated with the line card to present the interactive television services,

wherein the signal comprises a very high digital subscriber line signal, and

wherein the modified signal comprises a very high digital subscriber line signal, and

wherein the converted signal comprises a very high digital subscriber line signal.

10. The system of claim 9, wherein the operations further comprise enabling the line card to receive the modified signal at a preferred signal quality.

11. The system of claim 9, wherein the operations further comprise generating the modified signal by applying a sealing current that inhibits degradation to the minimally twisted pair cables to the signal.

12. The system of claim 9, wherein the operations further comprise transmitting synchronization signals to the line card.

13. The system of claim 9, wherein the minimally twisted pair cable has a transmission characteristic which affects a preferred signal quality for presenting interactive television services at customer premise equipment.

14. The system of claim 9, wherein the very high digital subscriber line signal is modified for fault isolation to identify locations of a fault.

15. The system of claim 9, wherein the modifying is performed by applying path error correction to the signal.

16. A non-transitory machine-readable storage medium, comprising executable instructions that, when executed by a processing system including a processor, facilitate performance of operations, comprising:

receiving a signal via minimally twisted pair cables, wherein the signal comprises a very high digital subscriber line signal;

applying a noise canceling filter to modify the signal, for transmission over the minimally twisted pair cables, to generate an updated signal, wherein the updated signal comprises a very high digital subscriber line signal; and

transmitting the updated signal to a line card to enable the line card to receive the updated signal and to convert the updated signal to a converted signal for presentation of interactive television services at customer premise equipment, wherein the converted signal comprises a very high digital subscriber line signal.

17. The non-transitory machine-readable storage medium of claim 16, wherein the operations further comprise applying line corrections to the updated signal generated by the noise canceling filter.

18. The non-transitory machine-readable storage medium of claim 16, wherein the minimally twisted pair cables have a transmission deficiency which prevents reliable delivery of the signal at a desired signal quality for presenting the interactive television services at the customer premise equipment.

19. The non-transitory machine-readable storage medium of claim 18, wherein the applying the noise cancelling filter overcomes the transmission deficiency.
