摘要: A test packet generator (225a) within a physical layer device (230) may generate packets to be communicated over closed communication path established the (230). The include pseudo-random bit sequence. receiver receive at least portion of generated packet. checker (225b) compare received with in order determine error rate for device. window counter (225c) count number bits and that are received. Accordingly, calculated based on ratio counted
