据《Communications International》1986年13卷8期报道:Carntec Electronics有限公司生产了一种高性能并带有分组装/拆和集中器的大吞吐量X.25 PAD交换设备。这种设备由一块CPU和存储器板、一张8端口通道卡和一张在板装的68000微处理器控制下,可提供高速同步X.25线路的4端口交换卡组成,能满足X.21/X.21 bis的要求。该设备共有14个端口,其中4个供异步操作专用,还有4个供X.25操作用,其余的可按需要,或配给异步或配给X.25使用。
According to Communications International, 1986, Volume 13, Number 8, report: Carntec Electronics Ltd produces a high-performance X.25 PAD switch with high throughput with splitter / splitter and concentrator. The device consists of a CPU and memory board, an 8-port channel card and a board-mounted 68000 microprocessor that provides a high-speed synchronous X.25 line 4-port switch card that meets X.21 /X.21 bis requirements. The device has a total of 14 ports, of which 4 dedicated for asynchronous operation, there are 4 for X.25 operation, the rest may be required, or allocated to asynchronous or X.25 use.
