符合CCITT標(biāo)準(zhǔn).主要功能:對(duì)交換機(jī)進(jìn)行通路荷話務(wù)量測(cè)試。
系統(tǒng)結(jié)構(gòu):1至8個(gè)測(cè)試單元通過系統(tǒng)總線與計(jì)算機(jī)相連,接受協(xié)調(diào)、統(tǒng)一的調(diào)度;測(cè)試單元通過用戶線接口與交換機(jī)相連。
系統(tǒng)容量:每測(cè)試單元含64線測(cè)試電路,8臺(tái)測(cè)試單元通過系統(tǒng)總線可復(fù)連成一個(gè)512線的測(cè)試系統(tǒng)。最多16個(gè)測(cè)試系統(tǒng)可復(fù)連成一個(gè)8192線的擴(kuò)展系統(tǒng)。
單元復(fù)連:測(cè)試單元間通過DB25復(fù)連電纜復(fù)連。不同測(cè)試單元中的測(cè)試電路在調(diào)度與時(shí)序控制中由計(jì)算機(jī)統(tǒng)一控制以保證呼損精度定位。
呼叫能力:測(cè)試單元典型呼叫能力為25.000呼叫/小時(shí)(雙音頻撥號(hào)、通路測(cè)試、32對(duì)線)。實(shí)際測(cè)試呼叫量與被測(cè)交換機(jī)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 telephone switching systems. The EF104A is a more sophisticated version than the EF101A. It simulates 64 telephone sets and provides such sophisticated functions as GPIB control, call mixing (which generates various types of calls simultaneously), and tone analysis. The EF104A can simulate a broad range of operations under a full range of light to excessive traffic loads.
