摘　　要：传统综合业务数字网(ISDN)终端与交换设备之间主要使用有线连接,周围环境以及传输距离都会影响其灵活性。针对此问题,在详细剖析了ISDN基本速率接口、ISDN接口专用芯片、总体设计方案和软件实现过程的基础上,设计并实现了一种专用无线远传设备,实现终端的无线引接功能。实际应用结果表明,设备性能稳定可靠,不仅提高了终端的便携性,而且增强了其环境适应性。The connection between traditional integrated services digital network terminal and network switching equipment is mainly wired,whose flexibility is affected by the surrounding environment and the transmission distance. To solve this problem,a kind of dedicated wireless remote transmission equipment is designed and implemented based on analyzing ISDN basic rate interface,ISDN interface ASIC,the system design plan and the software implementation process in order to realize wireless connection function of the terminal. The practical application results show that this equipment has stable and reliable performances,which not only improves the portability of the terminal,but also enhances its environmental adaptability.
