摘要
通过对符合ITU-T G.703建议的E1接口功能、电器特性、类型、输出口回损要求等特点,分析了G.703数字接口转换的实现原理,并从软硬件两个方面详细说明G.703与V.35,RS 232,V.36等多种接口之间的转换,其中涉及到电平转换和速率设置、数据的接收和发送、E1接口的控制及通信等设计要求。
The article analyses theory for transformation of digital interface of G. 703 through suggestion according with ITU - T G. 703 for E1 character of interface type, function, electric character and losing of output port. And explains multi - interrace transform among G. 703,V. 35, RS 232 and V. 36 from angle of hardware and software. Meanwhile the article shows many requirements involving in transform of electricity, sending and accepting for data, controlling of E1 interface and communication.
