摘　　要：本文提出了一种利用ＳＴＭ－４的开销处理芯片ＰＭ５３１２来实现ＳＴＭ－１６的开销处理的方式，并给出了相应问题的解决方法。特别是对影响系统性能的发送方向四片ＰＭ５３１２的数据相位对齐的问题进行了分析并给出了几种具体解决方案，经过试验取得了满意的结果。The STM 16 SOH processing by using PM5312 chips of STM 4 transport terminating transceiver are presented and, in particular, data phase alignments of 4×PM5312 chips on transmission direction which effect the system performance are analyzed in the paper. Furthermore the different solutions and implementations are given and compared with each other in detail. Experimental results show that improvements on system performances are achieved with the optimized circuit structures.
