ABSTRACT:
A method to divide upstream timeslots in a multiple access system that couples a line terminator via a tree-like network to a plurality of network terminators and the line terminator distributes downstream data packets to the plurality of network terminators. The line terminator includes a grant, associated with one of the network terminators, in the downstream packet. A network terminal, upon recognizing its associated grant in the downstream packet, transmits data in a packet placed in a predefined upstream timeslot. Depending on the type of line terminator (high or low order) and the placement of the grant in the downstream packet, the data transmitted by the network terminator, in response to the grant recognition, is placed in a high or low order timeslot for transmission to the line terminator.
