A method to divide upstream timeslots in a multiple access system that couples a line terminator (LT) via a tree-like network to a plurality of network terminators (NT1, NT2, . . . , NT16) and that distributes downstream data packets by the line terminator to the plurality of network terminators. The method includes the following steps: inclusion by the line terminator in a downstream data packet at a predefined place of a grant (TEA1; TEA2; . . . ; TEA16) being associated to one of the plurality of network terminators and distributing that downstream packet, reacting by the network terminator upon reception and recognition of its own grant by transmitting an upstream data packet in a predefined upstream timeslot. In the event when the network terminator is a lower order network terminator and the predefined place is a predefined first place, the upstream data packet are transmitted in a lower order timeslot. In the event when the network terminator is a higher order network terminator and the predefined place is a predefined first place, the upstream data packet is transmitted in one of a plurality of higher order timeslots, where the higher order timeslots are subslots of a predefined number of higher order subslots included in the predefined upstream timeslot. In the event when the network terminator is a higher order network terminator and the predefined place is a predefined second place, the upstream data packet is also transmitted in such higher order timeslot. |
