摘要

低比特率ISDN (2B+D)连接正在变得可用，特别是在PABX中。描述了一种允许IBM/sup TM/ PC兼容的计算机连接到ISDN的接口卡。该设计的创新之处在于，该接口作为COMx端口，遵循HAYES/sup TM/命令集，作为定制应用程序的内存映射接口，最后作为电话语音接口。HAYES/sup TM/模式允许用户利用市场上基于主机的通信软件。本文还讨论了为支持ISDN标准所要求的复杂硬件接口而选择的集成电路

An ISDN interface for the PC compatible

Low bit rate ISDN (2B+D) connections are becoming available especially within a PABX. An interface card is described that allows IBM/sup TM/ PC compatible computers to connect to the ISDN. The design is innovative in that the interface operates as a COMx port obeying the HAYES/sup TM/ command set, as a memory mapped interface for customized applications and finally as a voice interface for telephony. The HAYES/sup TM/ mode allows the user to take advantage of the host of communications based software on the market. The paper also discusses the integrated circuits chosen to support the complex hardware interfaces required by the ISDN standards.<>
