Abstract:
1. An Optical Line Termination (OLT) for exchanging data traffic in a Gigabit Passive Optical Network (GPON), comprising a controller programmed to generate a timeslot schedule for transport of a desired bandwidth of Constant Bit Rate (CBR) data traffic by selecting one or more timeslots from periodic frame clusters operating according to a GPON Transmission Convergence (GTC) protocol, wherein the controller is programmed to determine which Transmission Containers (T-Conts) in one or more ONUs provide CBR data traffic service (CBR T-Conts), and which T-Conts provide non-deterministic (ND) data traffic service (ND T-Conts), wherein each of the periodic frame clusters comprises a plurality of frames, wherein a portion of said frames is reserved for CBR and ND data traffic (“User Traffic Reserved Frames”), and at least one other portion of said frames is reserved for ND data traffic, and Operations, Administrative and Management (OAM) activity (“Residual Frames”), and wherein the controller is programmed to select the one or more timeslots for one or more CBR T-Conts from the User Traffic Reserved (UTR) Frames.
