( 2 ) introduce the constitutes and realization on the ground of vts / gps combination application ; it introduces the realization of vts software and gps automatic supervision system hardware. vts software discusses the applications of computer network technique in modem vts on the strength of the software that is developed by ourselves. while gps automatic supervision system hardware put emphasis on the principle of time - division and how to achieve the synchronous technique and the realization of hardware by use of gps second pulse
（ 2 ）介紹一個基於vts / gps組合應用的構成和實現：重點介紹系統的軟體和gps自動監測系統硬體的實現，軟體將以自行開發的軟體為基礎，探討計算機網路技術在現代vts中的應用實例， gps自動監測系統硬體將重點探討時分的原理和利用gps的秒脈沖進行同步的技術和硬體的實現。 -
Initially, pdh was introduced to improve and replace the obsolete analog frequency division multiplex ( fdm ) system. however, it was soon found that pdh had shortcomings such as difficulty in management, high construction cost, limited applications and lack of connectivity standards at the optical layer. thus, in the early 1990s, synchronous digital hierarchy ( sdh ) was introduced in the transmission system
Pdh最初引入是為了改進和替代老式的模擬頻分復用器系統，但很快被發現pdh管理困難、造價高、應用范圍窄，且缺乏在光層面上的連接標準，因此90年代初期， sdh （ synchronousdigitalhierarchy ）標準被首先引入了傳輸系統。 -
