摘要： An apparatus, method and system are provided for multimedia access network channel management, such as channel management in a hybrid fiber-coaxial cable network, for voice (telephony), video, fax and data transmission. The preferred system embodiment includes a plurality of cable telephony modems (CTMs), for such voice (telephony), video, fax and data transmission, and includes a cable modem termination system (CMTS). For upstream communication from the CTMs to the CMTS, the network provides a plurality of channels, formed by a combination of FDM and TDMA. When a CMTS receives an multimedia network access message having a comparative priority from a CTM, the CMTS determines whether there is a first channel which is available from the plurality of channels, and if so, assigns a first transmission corresponding to the multimedia network access message to the first channel. When there is no available first channel, the CMTS determines whether there is a second transmission on a second channel which is moveable to a third channel, and if so, reassigns the second transmission to the third channel and assigns the first transmission corresponding to the multimedia network access message to the second channel. When there is no available first channel and no second transmission which is moveable, the CMTS determines whether there is a third transmission on an assigned channel having a lower comparative priority than the comparative priority of the multimedia network access message, and when there is a third transmission, the CMTS removes the third transmission from the assigned channel to form a vacated channel, and assigns the transmission corresponding to the multimedia network access message to the vacated channel.
摘要翻译：提供了用于多媒体接入网络信道管理的装置，方法和系统，例如用于语音（电话），视频，传真和数据传输的混合光纤同轴电缆网络中的信道管理。优选的系统实施例包括用于这样的语音（电话），视频，传真和数据传输的多个有线电话调制解调器（CTM），并且包括电缆调制解调器终端系统（CMTS）。对于从CTM到CMTS的上行通信，网络提供由FDM和TDMA的组合形成的多个信道。当CMTS从CTM接收到具有比较优先级的多媒体网络接入消息时，CMTS确定是否存在可从多个信道获得的第一信道，如果是，则分配对应于多媒体网络接入消息的第一传输到第一个频道。当没有可用的第一信道时，CMTS确定在可移动到第三信道的第二信道上是否存在第二传输，如果是，则将第二传输重新分配给第三信道，并分配对应于多媒体的第一传输网络访问消息到第二个通道。当没有可用的第一信道且没有可移动的第二传输时，CMTS确定在具有比多媒体网络接入消息的比较优先级低的比较优先级的分配信道上是否存在第三传输，并且当存在第三信道传输时，CMTS从分配的信道中去除第三传输，形成空闲的信道，并将与多媒体网络接入消息相对应的传输分配给空闲的信道。

摘要： A method and system for synchronizing two clocks of a first and second device. Successive synchronization messages are sent from the first device to the second device. Each synchronization message has a timestamp. Each message is received at the second device and the period between successive timestamps is determined. The period of the second clock of the second device is also determined. The period between timestamps is compared with the period of the second clock of the second device. The period of said second clock is adjusted based upon the comparison.
