摘　　要：针对目前通信业内主流数字同步设备(SYNLOCK-V3)的实际运用情况,根据大量性能测试及调查研究结果,分析了其频偏检测机制、FREQ告警门限值、MTIE、TDEV模板设定、频率牵引范围等多个技术设计问题,或与业内通行标准值具有较大的差距。指出该类问题有关的不利影响,在此基础上提出了改进建议。The actual use for the current situation of the industry mainstream digital synchronous communicationdevice (SYNLOCK-V3), according to the a large number of performance tests and the results ofinvestigation, analyzed the frequency offset detection mechanism, FREQ alarm threshold, MTIE, TDEVtemplate set, frequency pulling range and other technical design issues, or with prevailing industrystandard values have a larger gap. He pointed out that the adverse effects related to this kind of problemand recommendations for improvements.
