Speedy Cutover Service, SXS switching cutover to ESS filmed live at Glendale CA central office, 1984
推荐理由
Total downtime was just 47 seconds.
说明
这是2015年由AT&T Tech Channel发布的一部纪录片,主题归在History of computing。它讲的是telephone switch cutover这一支里的具体问题,而不是把整个领域扫一遍。适合按兴趣直接看、不打算先补课的人。内容上可以概括成:A 1984 AT&T film showing the live cutover of a Glendale, California central office from step-by-step switching to an electronic switching system. Installers prepare the site and then cut cables in a coordinated operation.这些读者给出的理由,核心是:HN links it as a vivid example of high-stakes telco cutovers, done with careful coordination, big cable cutters and under a minute of downtime.讲法不绑某一条新闻,过几年仍然可以当材料看。从2018年到2025年,有2位不同的读者在2个不同月份把它推荐出来,其中明确叫别人去看的有0次。适合先建立人物和来龙去脉的人。看完要能说出这件事是怎么发生的。如果已经会了基本定义,就把注意力放在它怎么把telephone switch cutover变成能跟着复述的例子。
