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.
