瘖啞渠道；無聲渠道；傳聲筒；啞吧管道（dumb pipe）

意指無法提供加值，只是單純提供線路連線。

讀書筆記：

Operators of today’s networks worry about the possibility of them becoming, in the new ubiquitous network era, “dumb pipes”—by which they mean a highly commoditized infrastruc-ture that adds little to no value to the traffic it carries, as with today’s electrical grid, for example. 今天的網路營運商擔心他們在新的無所不在網路時代可能成了「瘖啞渠道」（dumb pipes）──意指高度商品化的基礎設施，對它所攜載的流量只增添微乎其微的價值，或者根本沒有增添價值，就像今天的電力網那樣。（資料來源：Anywhere: How Global Connectivity is Revolutionizing the Way We Do Business）
