Combined cable/DSL modem and method for high speed data communication

摘要

A combined cable/digital subscriber line (DSL) modem and method for data transmission. Upstream data is transmitted to a data communications network through a two wire pair to a central office using unidirectional DSL transmission. Downstream data is transmitted from the data communications network to the combined cable/DSL modem via a cable network using unidirectional cable transmission. Thus, bi-directional data communications is established using two unidirectional transmission links for faster and more efficient data communication.
