摘要： In one embodiment, a first ranging timing description describing at least a duration of time during which a subject cable modem (CM) may burst and a duration of time during which the subject CM and other CMs in a multiple access network are not permitted to burst is translated into a second ranging timing description describing a duration during which a burst from the subject CM is expected to be received by a cable modem termination system (CMTS). The CMTS is conditioned to receive a burst from the subject CM during the duration of time described by the second ranging timing description. A timing offset is determined from at least an actual time a burst from the subject CM is received by the CMTS and the duration of time during which the subject CM and other CMs in the multiple access network are not permitted to burst to produce a determined timing offset. The determined timing offset is reported to compensate for delay in the multiple access network and the subject CM.

摘要翻译：在一个实施例中，第一测距定时描述至少描述对象电缆调制解调器（CM）可能爆发的持续时间以及多址网络中的对象CM和其他CM不被允许爆发的持续时间被转换成第二测距定时描述，其描述期间来自主体CM的脉冲串预期将由电缆调制解调器终端系统（CMTS）接收的持续时间。 CMTS被调节为在由第二测距定时描述所描述的持续时间期间从主体CM接收突发。定时偏移至少由CMTS接收到来自主体CM的脉冲串的实际时间以及多路接入网络中的主体CM和其他CM不被允许突发产生确定的定时的持续时间来确定抵消。报告所确定的定时偏移以补偿多址网络和主体CM中的延迟。
