摘要:
An ISDN interface (88) is provided on a card (30) which is adapted for mounting in a terminal computer (10) and which is operable to exchange data with a terminal computer and an ISDN (16). The ISDN interface card (30) comprises a protocol processor (44) that is programmable to process data encoded in accordance with a number of different protocols, and a digital signal processor (46) that is programmable for data compression and encryption and facsimile applications, and mu -law and a-law conversion, among other applications. The ISDN card (30) dynamically allocates data calls between one or two B-channels to achieve a data transmission rate of 128 bps. A power supply (100) with a ring generator (122) is provided to allow for the use of an analog telephone (102) with the ISDN card (30). The ISDN card (30) is programmable to allow users to create customized screens for various call processes, and to allow for the updating of a flash ROM (52) coupled to the protocol processor (44) through the terminal computer (10) and the ISDN (16).
摘要(中):
ISDN接口(88)设置在适于安装在终端计算机(10)中并且可操作以与终端计算机和ISDN(16)交换数据的卡(30)上。 ISDN接口卡(30)包括可编程以处理根据多个不同协议编码的数据的协议处理器(44)和可编程用于数据压缩和加密和传真应用的数字信号处理器(46) 和法律转换,以及其他应用程序。 ISDN卡(30)在一个或两个B信道之间动态分配数据呼叫,以达到128bps的数据传输速率。 提供具有环形发生器(122)的电源(100)以允许使用具有ISDN卡(30)的模拟电话(102)。 ISDN卡(30)可编程为允许用户为各种呼叫处理创建定制屏幕,并且允许通过终端计算机(10)更新耦合到协议处理器(44)的闪存ROM(52)和 ISDN(16)。
