Abstract
In a cable data system, several frequency division multiplexed upstream data signals on an individual cable can be selectively routed to frequency-selective band pass filters using a relay matrix between the filters and the cable. By appropriately controlling the relays, the upstream information can be split out to as many different filters that might be required to recover the frequency division multiplexed information. Cabling installation to a cable modem termination system is simplified and maintenance costs are reduced by carrying multiple signals on one cable.
