A high-speed data transmission network system ( 8 ) is provided. The system ( 8 ) includes a plurality of subscriber premises ( 12 ) that transmit a first upstream signal ( 28 ) on a first frequency band to a central office or a remote terminal ( 10 ), which is in communication with the plurality of subscriber premises ( 12 ). The central office or the remote terminal ( 10 ) broadcasts a downstream signal ( 30 ) to each of the plurality of subscriber premises ( 12 ) on a second frequency band, which is higher in frequency than said first frequency band. The downstream signal ( 30 ) contains one or more subscriber group signals and a plurality of subscriber specific signals. A controller ( 44 ) provides each of the subscriber premises ( 12 ) access to one or more of the one or more subscriber group signals and to a corresponding subscriber specific signal of the plurality of subscriber specific signals.
