    摘要： A system and method is provided for estimating the T1 timing error and clock recovery errors by processing timing information from the associated pseudowire packet stream(s) from which the T1 is derived. The timing errors are presented as MTIE measurements which are used to present alarms for a Network Operation Control centre and are used to accurately alarm error conditions where the regenerated or derived T1 signal does not meet MTIE or clock accuracy errors. This alarm is intended to detect conditions of excessive packet jitter, wander or phase transients which may exist in the data network over which the pseudowire stream is transported. In another aspect, the errors are used to control the regeneration of the T1 clock information.

    摘要翻译： 提供了一种系统和方法，用于通过处理从其导出T1的相关伪线分组流中的定时信息来估计T1定时误差和时钟恢复错误。 定时误差表示为MTIE测量，用于向网络操作控制中心发出报警，并用于准确报警重新生成或导出的T1信号不符合MTIE或时钟精度误差的错误状态。 该警报旨在检测可能存在于传输伪线流的数据网络中的过多数据包抖动，漂移或相位瞬变的情况。 另一方面，错误用于控制T1时钟信息的再生。

    摘要： A distributed or centralized network backhaul delay system includes a plurality of cellular base transceiver stations. Each cellular base transceiver station includes a network backhaul delay element. The network backhaul delay element is configured to calculate delay information associated with network delays between cell sites. The network backhaul delay element is configured to adjust and shape the relative network delays to minimize network delays between cell sites to enable soft handoff to be performed.

    摘要： A fringe-effect vault antenna includes a communications vault having a non-conductive cover disposed substantially at ground level. An antenna element is positioned in the communications vault. A metallic reflector has an edge, positioned substantially parallel to the ground, where the metallic reflector and the edge are configured to cause an edge diffraction, or “fringe-effect” upon the RF fields of the antenna to cause those RF fields to diffract in a direction toward the ground.

    摘要： A system and method for managing information communication in a network includes a plurality of network nodes. A plurality of circuit emulation data flows are established between a first network node and at least a second network node. Different data transmission rates are assigned to each circuit emulation data flow such that the frequency of communicated packets is different at least for each circuit emulation data flow used for timing recovery to make the plurality of circuit emulation data flows substantially independent of each other. For example, different frame rates can be assigned to synchronous backhaul transmission links such that the frequency of the backhaul transmission rates is substantially independent of the circuit emulation flow rates.
