Abstract

A BCN network with BCN modems that enable network wired devices to communicate over a typical home coaxial network that may include passive splitters and different types of coaxial cable.

First claim

What is claim is:

1. A communication circuit comprising:
a transceiver operable to communicate in a coaxial cable network (CCN);
a controller that is operable to, at least:
connect to the CCN;
if upon connection to the CCN, the CCN has no network controller, then establish itself as a network controller of the CCN;
transmit first information on the CCN, the first information comprising information indicating when admission messages may be transmitted on the CCN;
receive an admission request message from a new node;
if the received admission request message is correctly received and the new node is authorized to join the CNN, then perform an admission procedure with the new node;
probe a communication link of the CCN connecting the communication circuit to the new node; and
adapt transmission parameters for the communication link based, at least in part, on the probe.

2. The communication circuit of claim 1 , wherein the CCN is a premises network.

3. The communication circuit of claim 1 , wherein the controller is operable to, if the received admission request message comprises errors, then transmit second information on the CNN, the second information comprising information indicating when a next admission message may be transmitted on the CNN.

4. The communication circuit of claim 1 , wherein the information indicating when admission messages may be transmitted on the CCN comprises time slot information.

5. The communication circuit of claim 1 , wherein the controller is operable to, based at least in part on the probe of the communication link, determine a distance between the communication circuit and the new node.

6. The communication circuit of claim 1 , wherein the controller is operable to, based at least in part on the probe of the communication link, develop an echo profile.

7. The communication circuit of claim 1 , wherein the controller is operable to adapt transmission parameters by, at least in part, adjusting transmission power of the transceiver.

8. The communication circuit of claim 1 , wherein the controller is operable to periodically probe each communication link between the communication circuit and another node of the CCN.

9. The communication circuit of claim 8 , wherein the controller is operable to develop an echo profile for each of the probed communication links.

10. A communication circuit comprising:
a controller that is operable to, at least:
connect to a Coaxial Cable Network (CCN);
if upon connection to the CCN, the CCN has no network controller, then establish itself as a network controller of the CCN;
transmit first information on the CNN, the first information comprising information indicating when admission messages may be transmitted on the CCN;
receive an admission message from a new node;
if the received admission message is correctly received and the new node is authorized to join the CNN, then perform an admission procedure with the new node;
probe a communication link of the CCN connecting the communication circuit to the new node; and
adapt transmission parameters for the communication link based, at least in part, on the probe.

11. The communication circuit of claim 10 , wherein the CCN is a premises network.

12. The communication circuit of claim 10 , wherein the controller is operable to, if the received admission message comprises errors, then transmit second information on the CNN, the second information comprising information indicating when a next admission message may be transmitted on the CNN.

13. The communication circuit of claim 10 , wherein the information indicating when admission messages may be transmitted on the CCN comprises time slot information.

14. The communication circuit of claim 10 , wherein the controller is operable to, based at least in part on the probe of the communication link, determine a distance between the communication circuit and the new node.

15. The communication circuit of claim 10 , wherein the controller is operable to, based at least in part on the probe of the communication link, develop an echo profile.

16. The communication circuit of claim 10 , wherein the controller is operable to adapt transmission parameters by, at least in part, adjusting transmission power of the transceiver.

17. A communication circuit comprising:
a controller that is operable to, at least:
connect to a Coaxial Cable Network (CCN);
if upon connection to the CCN, the CCN has no network controller, then establish the communication circuit as a network controller of the CCN;
transmit first information on the CNN, the first information comprising information indicating when admission messages may be transmitted on the CCN;
receive an admission message from a new node;
if the received admission message is correctly received and the new node is authorized to join the CNN, then perform an admission procedure with the new node; and
if the received admission message comprises errors, then transmit second information on the CNN, the second information comprising information indicating when a next admission message may be transmitted on the CNN.
