Abstract
A data communication system includes a head-end modem, which is adapted to transmit downstream data signals over a communication medium in a first frequency band and to receive upstream data signals over the communication medium in a second frequency band, each of the first and second frequency bands including multiple frequency bins. At least first and second customer-premises modems are coupled in parallel to the head-end modem via the communication medium so as to receive the downstream data signals transmitted by the head-end modem in the first frequency band, and to transmit the upstream data signals in the second frequency band subject to multiplexing of the second frequency band between the first and second customer-premises modems.
