<p>A system provides multiple Internet connection by employing a filter (220,222), which selectively filters a transmission frequency band, on the data upstream in a cable network system. The system includes subscribers (114,214), cable modems (112,212), filters (220,222), a HFC line (50), CMTSs (100,200) and multiple ISP host servers (102,202). Each subscriber (114,214) uses a specific frequency band in data upstream using the filters (220,222). Therefore, each subscriber (114,214) can be easily connected to a corresponding ISP server (102,202).</p> |
