一种综合业务数字网多端口设备的硬件研制

The hardware design for an ISDN multi BRI device

使用PCI总线技术和Motorola的通信控制器 (MC6 8MH36 0 )设计了一个综合业务数字网多端口设备 .该设备可以看作是一个提供了丰富线路资源的通用硬件平台 ,它提供至多 8个基本速率接口或其中任意几个基本速率接口的任意组合 ,为不同的高层应用服务 .

This paper presents the hardware design for an ISDN Multi BRI device using PCI bus technology and QMC. The multi BRI device can be looked upon as a universal hardware platform with plenty of line resource that can supply not more than 8 independent BRIs or random combinations of these 8 BRIs for various high layer applications.
