Abstract

A broadband communication channel access network comprises an Ethernet device disposed in a serving area interface. The Ethernet device serves as an Ethernet bridge for a neighborhood service area. The Ethernet device communicates with a plurality of customer premises modems in the neighborhood service area. An Ethernet switch disposed at a central office communicates with the Ethernet device via a fiber optic medium using an Internet Protocol over a second Ethernet standard. The Ethernet switch provides a packet data core network termination.

Claims (49)

2. The broadband communication channel access network of claim 1 , wherein the Ethernet device and the SAI are located on an easement.

3. The broadband communication channel access network of claim 1 wherein the SAI comprises a ground-level utility box, and wherein the Ethernet device is disposed in the ground-level utility box.

4. The broadband communication channel access network of claim 1 wherein the SAI comprises a box on a utility pole, and wherein the Ethernet device is disposed in the box on the utility pole.

5. The broadband communication channel access network of claim 1 wherein the SAI comprises an underground utility box, and wherein the Ethernet device is disposed in the underground utility box.

6. The broadband communication channel access network of claim 1 wherein the Ethernet device communicate with the plurality of customer premises modems using an Ethernet standard comprising a Twisted Ethernet standard, and wherein the Ethernet device is to communicate with at least two of the customer premises modems by a corresponding twisted pair line.

7. The broadband communication channel access network of claim 1 wherein the Ethernet device communicate with the plurality of customer premises modems using an Ethernet standard comprising a Twisted Ethernet standard, and wherein the Ethernet device is to communicate with at least two of the customer premises modems by a corresponding twisted pair telephone service line.

8. The broadband communication channel access network of claim 1 wherein the Ethernet device communicates with the Ethernet switch using an Internet Protocol over an Ethernet standard.

9. The broadband communication channel access network of claim 8 wherein the Ethernet standard comprises a gigabit Ethernet standard.

10. The broadband communication channel access network of claim 1 wherein the Ethernet device communicates with the plurality of customer premises modems using an Internet Protocol over an Ethernet standard with a digital subscriber line physical layer based on at least one of Data Over Cable Service Interface Specifications (DOCSIS), Asymmetric Digital Subscriber Line (ADSL), Very-high-data-rate Digital Subscriber Line (VDSL), Symmetrical Digital Subscriber Line (SDSL), and Multirate Digital Subscriber Line (MDSL).

11. The broadband communication channel access network of claim 1 wherein the Ethernet device comprises a first removable line card and a second removable line card, the first removable line card providing an F 1 interface, the second removable line card providing an F 2 interface.

12. A broadband communication channel access network comprising:

a first Ethernet device disposed in a serving area interface (SAI) to serve as an Ethernet bridge for a first neighborhood service area, the first Ethernet device to communicate with a plurality of customer premises modems in the first neighborhood service area; and

an Ethernet switch disposed at a central office, the Ethernet switch to communicate with the first Ethernet device disposed in the SAI via a fiber optic medium.

13. The broadband communication channel access network of claim 12 further comprising:

a second Ethernet device to serve as an Ethernet bridge for a second neighborhood service area, the second Ethernet device to communicate with a plurality of customer premises modems in the second neighborhood service area;

wherein the Ethernet switch also communicates with the remote Ethernet device via a fiber optic medium.

14. The broadband communication channel access network of claim 12 wherein the first Ethernet device communicates with the plurality of customer premises modems in the first neighborhood service area using an Internet Protocol over a first Ethernet standard comprising a Twisted Ethernet standard, and wherein the first Ethernet device is to communicate with at least two of the customer premises modems by a corresponding twisted pair line.

15. The broadband communication channel access network of claim 12 wherein the first Ethernet device communicates with the plurality of customer premises modems in the first neighborhood service area using an Internet Protocol over a first Ethernet standard comprising a Twisted Ethernet standard, and wherein the first Ethernet device is to communicate with at least two of the customer premises modems by a corresponding twisted pair telephone service line.

16. The broadband communication channel access network of claim 12 wherein the Ethernet switch communicates with the first Ethernet device over an Ethernet standard comprising a gigabit Ethernet standard.

17. The broadband communication channel access network of claim 12 wherein the first Ethernet device communicates with the plurality of customer premises modems in the first neighborhood service area using an Internet Protocol over a first Ethernet standard with a digital subscriber line physical layer based on at least one of Data Over Cable Service Interface Specifications (DOCSIS), Asymmetric Digital Subscriber Line (ADSL), Very-high-data-rate Digital Subscriber Line (VDSL), Symmetrical Digital Subscriber Line (SDSL), and Multirate Digital Subscriber Line (MDSL).

18. The broadband communication channel access network of claim 12 wherein the Ethernet switch is to switch packets between the first Ethernet device and at least one asynchronous transfer mode (ATM) switch, at least one access server (RAS), and at least one Internet Service Provider (ISP).

19. A method of providing an Ethernet-based digital broadband service, the method comprising:

installing an Ethernet device in a serving area interface (SAI) of a neighborhood service area that communicates via a fiber optic link with an Ethernet switch located in a central office, the Ethernet device to serve as an Ethernet bridge for Ethernet-based digital broadband service subscribers in the neighborhood service area; and

pre-wiring a plurality of customer premises in the neighborhood service area to the Ethernet device.

20. The method of claim 19 further comprising:

receiving a request of the Ethernet-based digital broadband service for the customer premise after said pre-wiring; and

activating the Ethernet-based digital broadband service for the customer premise based on the request.

21. The method of claim 20 wherein a telecommunication company provides the Ethernet-based digital broadband service and another mode of Internet access, wherein the customer premise is an existing customer of the telecommunication company for the other mode of Internet access at a time of said receiving the request.

22. The method of claim 21 wherein the request is received from the customer premise via the other mode of Internet access.

23. The method of claim 21 wherein the other mode of Internet access is digital subscriber line (DSL) service.

24. The method of claim 21 wherein the other mode of Internet access is a dial-up service.

25. The method of claim 20 further comprising:

providing an Ethernet-based DSL modem to the customer premise based on the request.

26. The method of claim 19 wherein said pre-wiring comprises contemporaneously pre-wiring all of the customer premises in the neighborhood service area to the Ethernet device.
