Abstract

A method of effectively setting and changing a Receive Channel Set (RCS) of a cable modem (CM) is provided.

The method includes: receiving, by a Cable Modem Termination System (CMTS), a Receive Channel Profile (RCP) with respect to a downstream physical layer of a CM; composing, by the CMTS, a plurality of channel configuration information required for setting the RCS of the CM with reference to the RCP; encoding, by the CMTS, the plurality of channel configuration information, and transmitting the encoded plurality of channel configuration information to the CM; transmitting, by the CM, an RCP with respect to a downstream physical layer to a CMTS; receiving, by the CM, a plurality of channel configuration information being composed with reference to the RCP and being required for setting the RCS; and setting, by the CM, the RCS using the plurality of channel configuration information.

Claims

1. A method of setting a Receive Channel Set (RCS) of a Cable Modem Termination System (CMTS), the method comprising:

receiving a Receive Channel Profile (RCP) with respect to a downstream physical layer of a cable modem (CM);

composing a plurality of channel configuration information required for setting the RCS of the CM with reference to the RCP; and

encoding the plurality of channel configuration information, and transmitting the encoded plurality of channel configuration information to the CM.

2. The method of claim 1, wherein the plurality of channel configuration information includes priority information used for setting the RCS.

3. The method of claim 1, wherein the RCP and the plurality of channel configuration information are stored in a table.

4. A method of setting an RCS of a CM, the method comprising:

transmitting an RCP with respect to a downstream physical layer to a CMTS;

receiving a plurality of channel configuration information being composed with reference to the RCP and being required for setting the RCS; and

setting the RCS using the plurality of channel configuration information.

5. The method of claim 4, wherein the setting sets the RCS using the channel configuration information including a top priority, and sets the RCS using the channel configuration information including a subsequent priority when the setting of the RCS fails.

6. A method of changing an RCS of a CMTS, the method comprising:

determining whether a predetermined RCS of a CM is changed;

composing a plurality of channel configuration information required for changing the RCS with reference to an RCP with respect to a downstream physical layer of the CM; and

encoding the plurality of channel configuration information based on a priority, and transmitting the encoded plurality of channel configuration information to the CM.

7. The method of claim 6, wherein the RCP corresponds to information stored in a table of the CMTS.
