Abstract
A system for use in connecting broadband voice and data signals to communications systems such as the telephone system. Due to the low pass filtering characteristics of a standard twisted pair used in conventional telephone access loops data band signals are attenuated more than voice band signals. The present invention provides apparatus and methods for interfacing data and voice band signals to a common communications medium, such as a twisted pair, while significantly reducing the influence of one frequency band on the other.
