摘要： An extended acknowledgement mechanism is provided. In one aspect, a source node provides an indication that extended acknowledgement is supported. In response, the source node receives from a destination node an acknowledgement that comprises a regular acknowledgement frame, an extended acknowledgement frame, a bidirectional acknowledgement frame including payload data or an extended bidirectional acknowledgement frame that includes payload data. In another aspect, an indication is received from a source node a frame that extended acknowledgement is supported. In response, a destination node transmits to the source node an acknowledgement that comprises a regular acknowledgement frame, an extended acknowledgement frame, a bidirectional acknowledgement frame including payload data or an extended bidirectional acknowledgement frame that includes payload data. The ability of nodes supporting extended acknowledgement may be indicated during registration, and propagated throughout the network domain, so as to avoid per-frame indication in subsequent communications.

摘要： The present disclosure outlines mechanisms, systems, methods, techniques and devices that reposition a RMC symbol in a TDD frame. In one aspect, a method queues data transmission units (DTUs) for transmission in a TDD OFDM communication system, with each of the DTUs occupying a single symbol partially or fully, or multiple symbols, of a series of symbols in a TDD frame. The method also forms a management symbol for transmission in a kth symbol position of the series of symbol positions, k>1. The method further transmits the symbols sequentially in the TDD frame.

摘要： A transceiver in the form of an integrated small form-factor pluggable (SFP) module is described. The SFP module may include a processor, a hybrid circuit, a transformer, a RJ45 connector and a SFP connector. The processor may be configured to perform functions as a serializer/deserializer (SerDes), a digital signal processor (DSP), an analog front-end and a line driver. The hybrid circuit may be configured to neutralize signals reflected from a transmit direction to a receive direction. The DSP may be configured to support communication according to a Very-high-bit-rate Digital Subscriber Line (VDSL) technology such as the G.Fast standard.
