粉質粘土-
Qe1 achieve the whole synchronization by software and hardware. during the course of the initialization of the qe1 system, the chip pm4354 can accomplish the task of synchronization of bit, frame and multiframe after the chip initialization by the software. after pm4354 accomplishes the bit synchronization, qel will read the status registers of the pm4354 to get the status of each el circuit and choose recovered clock of the specified the el circuit as the external timing source of the whole htc - 5200an equipment
Qe1系統在系統初始化時，通過軟體完成對硬體晶元pm4354的初始化工作后，便可利用該晶元完成4路e1的同步（位同步、幀同步和復幀同步） ；在pm4354完成時鐘提取的任務后， qe1通過不斷地訪問pm4354的狀態寄存器，獲得每路e1的狀態信息，在時鐘源的選擇原則下，選擇指定e1線路的恢復時鐘作為整個htc - 5200an節點設備的外部參考時鐘，從而解決了htc 5200an的中繼板卡由e1變為qe時所帶來的網同步時鐘源。 -
Thereby, the choice of external timing source brought by the changing from the el to qel has been resolved. in the related chapters, the paper will explain the arithmetic of synchronization of bit, frame and multiframe in the pm4354 hardware and describe the software arithmetic and hardware sketch map of net synchronization
本文在相關的章節中將詳細地給出pm4354硬體上完成位同步、幀同步和復幀同步的實現的演算法，並給出qe1在實現網同步過程中的軟體演算法和硬體電路示意圖以及在項目開發過程中，測試以上各種同步技術是否可行的技術方案。
