The present application relates to a method to share upstream bandwidth in a time division multiple access system that couples a line terminator (LT) via a tree-like network to a plurality of network terminators (NT1, NT2, ..., NT31, NT32). The method comprises the steps of, upon reception of a grant by a network terminator (NT2) from the line terminator (LT) and upon recognition of the grant as being associated to this network terminator (NT2), transmitting by the network terminator (NT2) an upstream data packet in an upstream timeslot and comprising in the data packet an overhead (O) in front of a payload (P). The method further comprises, in the event when the network terminator (NT2) is a higher order network terminator, transmitting the payload (P) in the upstream timeslot after a predefined time period (T) of a start of the upstream timeslot (T), and defining the predefined time period (T) substantially equal to a time-period needed to transmit a lower order overhead by a lower order network terminator. <IMAGE> |
