摘要：
A communication system comprises a plurality of line cards having transceivers coupled to a plurality of subscriber lines. Each line card has at least one active transceiver within the same vectoring group, and each line card also has vector logic capable of cancelling crosstalk induced by an active transceiver that is a member of the vectoring group. Further, the line cards are coupled to one another via a ring connection across which vectoring information is passed from one line card to the next. In the event of a failure of one of the line cards, the failed card is bypassed by the vectoring stream so that the operational line cards can continue crosstalk vectoring operations despite such failure.
摘要（中）：
通信系统包括具有耦合到多个用户线的收发器的多个线路卡。 每个线路卡在相同的向量组内具有至少一个有源收发器，并且每个线路卡还具有能够消除由作为向量组的成员的有源收发器引起的串扰的向量逻辑。 此外，线卡通过环形连接彼此耦合，通过该环连接向导信息从一个线卡传递到下一个线卡。 在线卡之一发生故障的情况下，故障卡被矢量流旁路，使得即使发生故障，运行线路卡也可以继续进行串扰向量运算。
