通訊接口 RS-232,GP-IB

符合CCITT標準. 主要功能: 對交換機進行通路荷話務(wù)量測試。

系統(tǒng)結(jié)構(gòu)：1至8個測試單元通過系統(tǒng)總線與計算機相連，接受協(xié)調(diào)、統(tǒng)一的調(diào)度；測試單元通過用戶線接口與交換機相連。

系統(tǒng)容量：每測試單元含64線測試電路，8臺測試單元通過系統(tǒng)總線可復(fù)連成一個512線的測試系統(tǒng)。zui多16個測試系統(tǒng)可復(fù)連成一個8192線的擴展系統(tǒng)。

單元復(fù)連：測試單元間通過DB25復(fù)連電纜復(fù)連。不同測試單元中的測試電路在調(diào)度與時序控制中由計算機統(tǒng)一控制以保證呼損精度定位。

呼叫能力：測試單元典型呼叫能力為25.000呼叫/小時（雙音頻撥號、通路測試、32對線）。實際測試呼叫量與被測交換機響應(yīng)速度有關(guān)。

The Anritsu EF104A is a Call Simulator, with HPIB and RS-232C interface. It is used for development, manufacturing and testing digital ephone switching systems.
