摘要： A wideband multi-tone transceiver system interoperable with Asymmetric Digital Subscriber Line (ADSL) transceiver system, and including a two-step transceiver system having a discrete multi-tone transceiver system and a cosine modulated filter bank (CMFB) transmultiplexer. The two-step transceiver system provides a physically transparent transmission channel to each sub-band signal by minimizing the interference between sub-bands regardless of the transmission channel characteristics. The two-step transceiver system is realized with a comparably simple structure, and the circuit size is drastically reduced by sharing the FFT function with other sub-channels with the maximal utilization of the high-speed circuit when realizing each sub-channel's DMT modulation and demodulation function.

摘要： Provided are method and apparatus for dynamically allocating unlink bandwidth in Ethernet PON. In the method and apparatus, report value, which are received for each logical link identifications (LLID), is controlled to be less than a maximum gate value set for each LLID in sequence for all of LLIDs without a predetermined interval. A gate having a length corresponding to the restricted report value is generated. LLIDs are grouped into classes and processing is done class by class. For each class processing, if maximum processing time is reached or maximum total allocation is reached, the processing is switched to a lower class. Also each class processing, if any higher class has its maximum yield processing time or maximum yield allocated gate reached, the processing is switched to that higher class.
