Abstract

Digital subscriber line (DSL) head-end. The invention uses downstream broadcast from DSL Head End to subscribers and slicing of upstream data from the subscribers to the DSL Head End or point-to-point upstream. Multiple lines are driven simultaneously thereby significantly lowering central office hardware costs. A peripheral, DSL Head End is added to a cross-connect box, or a next generation digital loop carrier (NG-DLC), to facilitate broadband Internet and video service capabilities. A DSL Head End may be added to each cross-connect box, or to each distribution area to provide an efficient cost-effective solution for provisioning DSL service.

Claims

1. A digital subscriber line system, comprising:

a digital subscriber line head-end that is operable to broadcast data downstream to at least one user; and

at least one customer premises equipment communicatively coupled to said digital subscriber line head-end,

wherein said customer premises equipment is operable to extract a payload data portion of the broadcast data and to forward said extracted payload data portion to a user and further operable to assemble a frame from data provided by said user and to transmit said frame upstream to said digital subscriber line head-end; and

said digital subscriber line head-end is operable to perform slicing of said frame that is transmitted upstream.

2. The digital subscriber line communication system of claim 1, wherein the slicing of the frame that is transmitted upstream comprises time-division multiple access processing.

3. The digital subscriber line communication system of claim 1, wherein the slicing of the frame that is transmitted upstream comprises code division multiple access processing.

4. The digital subscriber line communication system of claim 1, wherein the data that are broadcast downstream comprise an IEEE compatible 802.3 frame

5. The digital subscriber line communication system of claim 1, wherein the frame that is transmitted upstream from the user comprises a fragmented IEEE compatible 802.3 frame.

6. A digital subscriber line system, comprising:

a digital subscriber line head-end that is operable to broadcast data downstream to a plurality of users; and

a plurality of customer premises equipment units communicatively coupled to said digital subscriber line head-end, each of said customer premises equipment units being operable to extract a payload portion of the data broadcast downstream and to forward said extracted payload portion of said data to a user, each of said customer—

provided equipment further being operable to collect data from a user and to transmit said user data upstream to a receiver using point-to-point protocol.

7. A distribution apparatus for a digital subscriber line, comprising:

a digital subscriber line head-end;

a cross-connect box that is communicatively coupled to a central office via a first set of communication cables and communicatively connected to said digital subscriber line head-end via a second set of communication cables; and

at least one customer premises equipment unit communicatively connected to said digital subscriber line head-end, said customer premises equipment being provided broadband data services upon detection by said digital subscriber line head-end.

8. The distribution apparatus according to claim 7, said first set of cables comprising F1 distribution cables communicatively connected to a central office, said second set of cables comprising F2 distribution cables communicatively connected to said digital subscriber line head-end.

9. A distribution apparatus for a digital subscriber line, comprising:

a cross-connect box that is communicatively coupled to a central office via a first set of F1 communication cables;

a digital subscriber line head-end communicatively coupled to said F1 distribution lines in said cross-connect box; and

at least one customer premises equipment unit communicatively connected to said digital subscriber line head-end, said customer premises equipment being provided broadband data services upon detection by said digital subscriber line head-end.

10. The distribution apparatus for a digital subscriber line of claim 9, wherein

said digital subscriber line head-end is operable to broadcast data downstream to at least one user;

and

said customer premises equipment communicatively is coupled to said digital subscriber line head-end, and said customer premises equipment is operable to extract a payload data portion of the data that are broadcast downstream and to forward said extracted payload data portion to the user and further operable to assemble a frame from data provided by said user and to transmit said frame upstream to said digital subscriber line head-end; and

said digital subscriber line head-end is operable to perform slicing of said frame that is transmitted upstream.

11. The distribution apparatus for a digital subscriber line of claim 10, wherein the slicing of the frame that is transmitted upstream comprises time-division multiple access processing.

12. The distribution apparatus for a digital subscriber line of claim 10, wherein the slicing of the frame that is transmitted upstream comprises code division multiple access processing.

13. A distribution apparatus for a digital subscriber line, comprising:

a cross-connect box that is communicatively coupled to a central office via a first set of F1 communication cables;

a digital subscriber line head-end that is operable to broadcast data downstream to a plurality of users; and

a plurality of customer premises equipment units communicatively coupled to said digital subscriber line head-end, each of said customer premises equipment units being operable to extract a payload portion of the data broadcast downstream and to forward said extracted payload portion of said data to a user, each of said customer—

provided equipment further being operable to collect data from a user and to transmit said user data upstream to a receiver using point-to-point protocol.

14. A digital subscriber line communication method, comprising:

broadcasting data downstream from a digital subscriber line head-end;

extracting a payload portion of said broadcast data;

forwarding the payload portion of said data to at least one user within a plurality of users;

assembling a frame from data provided by at least one user;

transmitting said frame upstream to the digital subscriber line head-end; and

slicing said frame that is transmitted upstream using the digital subscriber line head-end.

15. The digital subscriber line communication method of claim 14, further comprising slicing the frame that is transmitted upstream using time-division multiple access processing.

16. The digital subscriber line communication method of claim 15, further comprising slicing the frame that is transmitted upstream using code division multiple access processing.

17. The digital subscriber line communication method of claim 14, wherein the data that are broadcast downstream comprise an IEEE compatible 802.3 frame.

18. The digital subscriber line communication method of claim 14, wherein the data that are broadcast upstream from the user comprise a fragmented IEEE compatible 802.3 frame.

19. A digital subscriber line communication method, comprising:

broadcasting data downstream from a digital subscriber line head-end;

extracting a payload portion of said broadcast data;

forwarding the payload portion of said data to at least one user within a plurality of users;

assembling a frame from data provided by at least one user;

transmitting the frame upstream to a receiver using point-to-point protocol.
