Abstract
A method and system for providing management functionality with a cable modem with telephony return is provided. The cable modem with telephony return is used for providing management functionality such as maintenance and signaling via the lower bandwidth telephony return path, leaving more higher bandwidth cable television channels free for data transmission. Since routine management functions such as maintenance are completed on the cable television channels via the telephony return path, the overall costs of maintaining the higher bandwidth cable television channels are reduced. In addition, since routine management functions are carried out via the telephony return path, fewer overall maintenance functions need to be carried out on the higher bandwidth cable television channels, requiring less down time and generating more revenues for the cable television network providers.
