基于可编程逻辑器件的G.703接口与以太网数据转换模块的设计

Data Conversion Module Design of G.703 Interface and Ethernet Based on PLD

G.703是电力系统、部队系统等国有大型系统中数据传输网络中普遍的接口标准,而以太网则是当今现有的最通用的通信协议标准,二者之间的通讯接口转换具有较强的实用价值和意义。为此,提出一种基于可编程逻辑器件的接口转换模块的设计,主要包括转换模块电路的硬件电路开发、逻辑算法设计。该接口转换模块的逻辑部分采用可编程逻辑器件进行设计,具有处理速度快、控制灵活、便于升级维护等特点,应用效果良好。

G.703 interface is the normal standard interface in the large communicate system 9 especially in the electricity or army system. Ethernet is the most popular communicate protocol. There is stronger significant to make com-municate between them. Therefore, we designed the transform module based on PLD, which mainly included the hardware circuit development of the conversion module circuit and logic algorithm design. The logic part of the interface conversion module was designed with PLD, which has high processing rate, strong flexibility and update easily. It has good application effect.
