Abstract
Methods and systems pertaining to automatically and locally terminating a telephone dial-up connection to a data network are presented as an alternative to an inactivity timeout set by the cable television network headend. A cable modem in a data-over-cable system with telephony return is connected on an upstream telephone dial-up connection to a data network such as the Internet. The cable modem monitors a network interface for incoming data transmission activity from consumer premise equipment, including a personal computer system, connected to the cable modem. If the cable modem determines no incoming data transmission activity, the cable modem begins to query the status of the consumer premise equipment. If the consumer premise equipment does not respond to repeated queries within a specified time, the cable modem terminates the telephone dial-up connection.
