1. A method of providing dedicated upstream bandwidth to each of a plurality of subscriber locations for transmitting to a common point of distribution via an HFC network, comprising:

  • assigning, by the point of distribution, at least one of a predetermined number of time slots within each of repeating upstream transmission windows to each of the plurality of subscriber locations;

    transmitting, by the point of distribution, a windowing signal to each of the subscriber locations;

    encapsulating, by each subscriber location, subscriber data into data cells, each data cell suitable for a burst transmission within a time slot of predetermined duration;

    determining, by each subscriber location, relative timing of each time slot within each of the repeating transmission windows based on the windowing signal and a predetermined transmit offset value; and

    burst transmitting, by each subscriber location, subscriber data cells within programmed time slots to the point of distribution.
