开销字节 meaning in English
overhead byte
Examples
- The major problems found in the test was that some overhead bytes of the stm - 1 signal processed on those exchanges were inconsistent with those in the transmission system . this would to some extent undermine the effective cooperation of the nm function between the exchange and the transmission system , obstruct the alarm judgement and locating and impede the realization of the protection rotation function
测试发现主要问题是各交换机stm - 1信号的部分开销字节与传输系统不一致，这会在一定程度上影响交换机与传输系统二者的网络管理功能的有效配合，影响告警的判断与定位，影响保护倒换功能的实现。 - It was proved that shanghai bell s p3s exchange could not terminate some alarm overhead bytes . instead , it sent back those bytes to mistake local errors for far - end faults . we suggest that shanghai bell terminate such bytes , improve the frame synchronization detection function and the processing of s1 bytes , and add far - end error indication on the multiplexing segment and low - order and high - order channels and far - end out - of - work indication on the low - order channel
测试结果表明，上海贝尔p3s交换机不能够终结某些告警开销字节，而是将这些字节进行回传，从而将本端的错误误认为是远端的错误，建议上海贝尔p3s交换机按终结方式处理这些字节，完善帧同步检测功能和对s1字节的处理，并增加复用段远端差错指示功能、高阶通道远端差错指示功能、低阶通道远端差错指示功能和低阶通道远端失效指示功能等传输告警功能。 - Basic interoperability test is designed to check alarms on physical connections , the error rate of information delivery and the 2mbits cross - connect state when stm - 1 signals pass the transmission system . high - level interoperability test is to check the consistency of generated against readout overhead bytes , alarms and the performance monitoring as well as the synchronization , protection rotation , the interworking possibility of nm information and the o & m capability
基本互通能力测试包括：检查物理连接是否告警，检查信息传送有无差错，交换机stm - 1经过传输系统进行2mbits交叉连接的测试；高层次互通能力测试包括：开销字节产生和读出的一致性，告警一致性，性能监视一致性，同步，保护倒换，网管信息互通的可能性及维护操作能力的测试等。
