我单位已研制成功A型分组组装拆卸设备——pAD—A。它是公用分组交换数据网重要的网络装置之一,可以实现CCITT x.3,X.25,X.28和x.29的各项规程和协议,是异步终端和计算机进网必不可缺少的装备。
My unit has successfully developed type A group assembly and disassembly equipment - pAD-A. It is one of the most important network devices for public packet-switched data networks and can implement the protocols and protocols of CCITT x.3, X.25, X.28 and x.29. It is indispensable for asynchronous terminals and computers to access the network equipment.
