Dual-BUS

基本解釋

Formerly known as QPSX (Queued Packet and Synchronous Exchange), now known as DQDB (Distributed Queue Dual Bus).It was approved in 1990.
原來的名稱為QPSX（隊列分組同步交換），現(xiàn)名為DQDB（分布式隊列雙總線），1990年獲得批準。
In order to avoid single-chip processor's I/O operation interfering with DSP, CPLD extends dual bus for single-chip processor.
為避免單片機I/O操作時干擾DSP子系統(tǒng)，通過CPLD為單片機擴展雙總線。
IEEE standard for MANs (Metropolitan Area Networks). Formerly known as QPSX (Queued Packet and Synchronous Exchange), now known as DQDB (Distributed Queue Dual Bus). It was approved in 1990.
IEEE關于城域網(wǎng)標準。原來的名稱為QPSX（隊列分組同步交換），現(xiàn)名為DQDB（分布式隊列雙總線），1990年獲得批準。
This paper proposes a DQDB integrated sevice local area network,It is configured in optical fiber dual bus structure,using DQDB protocol and can integrate voice, high/low spced data,high quality picture and isochron convocation video.
介紹了一種DQDB綜合業(yè)務局域網(wǎng)。該網(wǎng)用光纖作傳輸媒介，拓撲結構為雙總線環(huán)形，采用DQDB協(xié)議，本網(wǎng)可傳輸數(shù)字話音、高/低速計算機數(shù)據(jù)、高質量靜止圖像和壓縮視頻圖像等綜合業(yè)務。
