Abstract

A method and apparatus for handling internet access telephone calls made via cable company telephone services. A head end data terminal receives cable signals and converts them into individual signals. An intelligent switch detects signals destined for an internet service provider and routes those signals on a separate path to the internet service provider. A central switch routes the other signals along a telephone network. A computer program can control the steps of receiving cable signals, converting them into voice band signals, routing the signals that are not for the intended recipient to a central switch, multiplexing the signals for the intended recipient together, and sending the multiplexed signals to the intended recipient.
