Abstract
A method for information transfer allowing for native transfer of voice, data, and any other digital service information over a passive optical network, comprising; the LT transmitting downstream in serially ordered frames broadcast to all of the NT's at a fixed interval; the NT's transmitting upstream in serially ordered frames, said frames being divided into serially ordered time slots, at most one NT transmitting information for at most one service type in each slot; the LT and the NT's exchanging management information, and the LT and the NT's natively transporting service information to each other in both the upstream and downstream directions, according to said management information exchanged between the LT and the NT's.
