A method and system provide an approach to support the aggregation of multiple broadband services including voice, high speed data, video and image through the transmission of packets and cells simultaneously over a passive optical network. The method of communication between a central terminal and plural remote terminals over a passive optical network includes transmitting downstream data from the central terminal to the plural remote terminals in successive downstream frames over a downstream network portion and transmitting upstream data from the plural remote terminals to the central terminal in respective upstream timeslots over an upstream network portion, the upstream timeslots forming successive upstream frames. The downstream data includes downstream packet data and downstream ATM cell data and the upstream data including upstream packet data and upstream ATM cell data. The upstream data can be transmitted from at least one of the plural remote terminals in multiple upstream timeslots which can be non-contiguous.
