摘要： In one aspect of the present invention, a network gateway is configured to facilitate on line and off line bi-directional communication between a number of near end data and telephony devices with far end data termination devices via a hybrid fiber coaxial network and a cable modem termination system. The described network gateway combines a QAM receiver, a transmitter, a DOCSIS MAC, a CPU, a voice and audio processor, an Ethernet MAC, and a USB controller to provide high performance and robust operation.

摘要： A method and system of processing sampled voice packets from a voice packet sender for transmission over a bit-rate sampled data transmission system, such as by a cable modem over a cable modem termination system, to a voice packet recipient. Unsolicited grant arrivals in response to a request from the voice packet sender coupled to the cable modem are determined. The storing of sampled voice packets is synchronized with the unsolicited grant arrivals. Upon receipt of an unsolicited grant arrival, currently stored sampled voice packets are transmitted to the cable modem for further transmission to the voice packet recipient over the cable modem termination system.

摘要： A filter settings generation operation includes sampling a communication channel to produce a sampled signal. The sampled signal is spectrally characterized across a frequency band of interest to produce a spectral characterization of the sampled signal. This spectral characterization may not include a signal of interest. The spectral characterization is then modified to produce a modified spectral characterization. Filter settings are then generated based upon the modified spectral characterization. Finally, the communication channel is filtered using the filter settings when the signal of interest is present on the communication channel. In modifying the spectral characterization, pluralities of spectral characteristics of the spectral characterization are independently modified to produce the modified spectral characterization. Modifications to the spectral characterization may be performed in the frequency domain and/or the time domain. One particular spectral modification that is performed is raising of the noise floor of the spectral characterization to meet a budgeted signal-to-noise ratio. Other spectral modifications include modifying spectral components corresponding to an expected interfering signal. In modifying these spectral characterizations, spectral components corresponding to a plurality of expected interfering signals may be modified.
摘要翻译：滤波器设置生成操作包括对通信信道进行采样以产生采样信号。采样信号在感兴趣的频带上进行频谱表征，以产生采样信号的频谱表征。该光谱特性可能不包括感兴趣的信号。然后修改光谱表征以产生修改的光谱表征。然后基于修改的光谱表征生成滤波器设置。最后，当感兴趣的信号存在于通信信道上时，使用滤波器设置对通信信道进行滤波。在修改光谱表征时，光谱特性的多个光谱特征被独立地修改以产生修改的光谱表征。频谱表征的修改可以在频域和/或时域中执行。执行的一个特定频谱修改是提高频谱表征的本底噪声以满足预算的信噪比。其他频谱修改包括修改对应于预期干扰信号的频谱分量。在修改这些频谱表征时，可以修改对应于多个预期干扰信号的频谱分量。
