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.
Claims21
A method for transporting data services natively over a passive optical network (PON), comprising:
- forming a downstream frame having a fixed length, wherein the downstream frame includes at least a fixed length physical layer operations, administration, and management (PLOAM) block, the downstream frame is dynamically divided into variable size data blocks;
- natively encapsulating data of data services in the variable size data blocks of the downstream frame;
- and
- broadcasting the downstream frame by a line terminal (LT) to network terminals (NTs) of the PON, wherein the natively encapsulating realizes the transport of data services according to their original service type without conversion into a single service type.
A method for transporting data services natively over a passive optical network (PON), comprising:
- forming an upstream frame by dividing time allocated for upstream transmission into fixed length slots;
- allocating a variable number of consecutive slots in the upstream frame for each network terminal (NT) of the PON according to a grants map;
- by each NT, dividing the consecutive slots allocated for the NT to a variable number of native blocks having a variable block size;
- inserting information of a particular service type of a data service in a single block;
- and
- wherein the native blocks realize the transport of data services according to their original service type without conversion into a single service type.
