摘要
全双工智能通信卡是在一对电话线（或双绞线）上实现全双工基带数据传输而设计的网卡。它具有高速的光电隔离和自保护功能，传输距离和速率分别可达１０ｋｍ和６４ｋｂ／ｓ，适用于现有网上的通信软件。本文详细地叙述了它的设计思想、硬件系统和实现功能，同时给出了该卡的有关实验结果、适用环境和范围。
In order to implement transmission of full-duplex baseband data,the intelli-gent card is designed.It has the capability of photoelectric isolation and self-protection,the transmission distance and rate are up to 10 Km and and 64 kb/s seperatelly,and all kinds of communication software on present networks can be used on this card.Its design idea,hardware system and implementation functions are introduced.Some experiment results as well as the application fields are also given.
