Title: Processing architecture for passive optical network

Abstract: In a network termination device integrated circuit in a point-to-multipoint network, a receiver receives a downstream transmission from a line termination unit within the point-to-multipoint network, a transmitter transmits an upstream transmission to the line termination unit within the point-to-multipoint network, and an internal processor operatively coupled to the receiver processes sub-fields within the overhead field of the downstream transmission. The internal processor is also operatively coupled to the transmitter to assemble the overhead field of the upstream transmission. The downstream transmission is an downstream transmission convergence frame format having an overhead field and a payload field, and the upstream transmission is an upstream transmission convergence frame format having an overhead field and a payload field.
