BROADBAND DATA TRANSFER IN A CABLE TELEVISION NETWORK

摘要

A communication system for relaying a data signal in a coaxial cable network adapted for transferring a cable television signal, which communication system comprises a first data network connection point for entering a baseband broadband data signal to said communication system; a modulating unit for forming a modulated data signal of said baseband broadband data signal, which modulated data signal comprises at least two logically connected but to different data transfer channels modulated signal components; a combiner adapted for said coaxial cable connection for adapting said modulated data signal to its own frequency channel to be relayed with said coaxial cable connection; a separator for separating said modulated data signal to separate signals; a demodulating unit for demodulating and connecting said signal components into a baseband broadband data signal; and a second data network connection point for relaying the baseband broadband data signal further to at least one node point of a data processing device.
