        分接同步部分由控制脉冲形成电路、帧定位电路及告警电路等组成。34Mb/s输出盘由缓冲存储器、消插控制、编码、锁相环和失锁检出等电路组成。监视和告警通信系统中某些设备或某通信设备的某个部位发生故障时,应该有相应的告警显示,以便采取相应措施。有的故障要立即维护,并向下游设备发出指示信号;有的只要维护人员引起注意。采用ASI告警指示信号是数字系统维护的一个重要手段,其作用是当上游设备站出现紧急告警时使下游设备站不要引起连锁反应。方法是:当上游发生紧急故障时,在给出紧急告警的同时,向下游发送全“1”信号。当收到AIS信号时。知道是上游除了问题,本设备不必过问。[2]数字线路段(Digitallineseetion)是指在单一类型的制造好的传输媒质(比如对称线。

        [3]异源复接需要插入的有帧同步码10位,告警码一位,备用一位,共12位(每支路3位)。除此外,还有为调整码速用的插入码。按ITU-T的规定,工作在8448kbit/s并采用正码速调整的二次群数字复接设备,其帧长为848bit(帧周期约为100μs),相当于每个基群为212个码(包括信码和插入码)[2]。相位抖动正码速调整过程引起的抖动主要有以下几个部分:由插入标志码的插入和抽出引起的以帧为周期的抖动。由帧定位信号的插入和抽出造成的以帧为周期的抖动。由支路信码瞬时速率调整(插入调整比特)而引起的随机抖动,根据实际设备不同,大约每2.5帧插入一次调整比特候时抖动。对于二次群复接设备来说,第(1)种抖动的频率约为40kH。
