Patent ID: 7760734

Claim:
A receiver of a TDMA (time division multiple access) PON (passive optical network) OLT (optical line terminal) system configured to transmit downstream a larger amount of data from an OLT to an ONT (optical network terminal) than to transmit upstream an amount of data from the ONT to the OLT, the receiver comprising: optical transceivers configured to extract data from optical signals transmitted upstream in a burst mode in a TDMA PON and the optical transceivers configured to generate internal frames from upstream directed data and to transmit downstream the internal frames such that the internal frames include destination TDMA PON port information, frame identification information, and a bandwidth matching a maximum amount of downstream traffic; TDMA PON MAC (medium access control) processors configured to recover TDMA PON frames from the upstream extracted data and the TDMA PON MAC processors configured to be able to receive internal frames downstream transmitted from a switch and to convert the internal frames into TDMA PON frames; the switch configured to multiplex the TDMA PON frames received upstream from the TDMA PON MAC processors into internal frames and to transmit the multiplexed internal frames to a packet processor and configured to be able to transmit downstream the internal frames received from the packet processor to every TDMA PON MAC (medium access control) processors coupled to the switch; and the packet processor configured to upstream recover and to upstream process Ethernet frames or packets from received internal frames, and configured to generate internal frames from downstream directed data and to transmit downstream the internal frames such that the internal frames include destination TDMA PON port information, frame identification information, and a bandwidth matching a maximum amount of downstream traffic.
