    • An agitation element adapted for use with other agitation elements on the rollers of a roller screen, having a substantially planar and triangular body with a central opening therethrough for mounting the agitation element onto the roller, the opening being adapted such that the body of the agitation element lies generally perpendicularly with respect to the axis of rotation of the roller when the agitation element is mounted on the roller for operation. Another agitation element has an edge defining a closed perimeter with substantially linear sides, each side being angled with respect to each adjacent side by less than ninety degrees. In particular embodiments, the angle can be as low as approximately sixty degrees. Still another agitation element incorporates a body having an edge defining a closed polygon with adjacent sides that intersect each other at a peak and wherein a maximum distance, measured from the geometric center of the polygon to at least one of the peaks is approximately 1.5-2.25 times greater than a minimum distance, measured from the geometric center of the polygon to the midpoint of one of the sides. In particular embodiments, the ratio can be 1.5-1.75, and in one particular embodiment, the ratio is approximately 1.6.

    • The apparatus and method herein provide a means for actively monitoring a communications node for datapath disruptions caused within the node. It was developed to address linecard failures that were detected in the field and for which traditional error detection mechanisms such as CRC and OAM CC checks are not feasible. According to one implementation, statistics are collected over a preset time interval. If any egress cell counts are zero over a full interval, then the ingress interface for that datapath is determined, e.g. using the node's cross-datapath information, and the corresponding linecard of that ingress interface is contacted to determine the ingress cell count. If the ingress cell count is non-zero then the datapath is alarmed since the complete lack of cells transmitted at the egress indicates a datapath disruption. Other implementations that can detect datapath disruptions without a complete interval of statistics collection and which do not require a zero egress cell count are possible for cases where congestion, linecard resets, etc. can be ruled out.
    • 本文的装置和方法提供了用于主动监视通信节点以在节点内引起的数据路由中断的手段。 它被开发用于解决在现场检测到的线卡故障,并且传统的错误检测机制如CRC和OAM CC检查是不可行的。 根据一个实施方式,在预设的时间间隔内收集统计数据。 如果任何出口单元在整个间隔内为零,则确定该数据路径的入口接口,例如, 使用节点的跨数据路径信息,并接触该入口接口的相应线卡,以确定入口单元数。 如果入口单元计数不为零,则数据通路将被警告,因为在出​​口处完全缺少单元格指示数据路径中断。 可以排除拥塞,线卡复位等情况的其他可以在没有完整的统计信息收集间隔并且不需要零出口单元数的情况下检测数据路径中断的实现。
