@wyatt Bringing your own modem is indeed good advice for subscribers to a cable Internet provider that lets them do so. I had my own Arris SurfBoard during the last couple years that I was with Xfinity.

DOCSIS 3.1 signal drowns in noise 300 000 non-correctables in a minute.

The modem switches modulation like a windmill in a storm and occasionally drops 3.1. The end result being that the modem cable connection heats up to 47 °C which probably isn't helping at all.

Hardware I returned to Xfinity this afternoon. The Arris telephony modem was about 20 years old. The cable box / DVT was not much younger.

We dropped cable TV, VOIP, and stopped renting modems (bought my own Arris S33v3) very recently, saving hundreds of dollars per month on the bill.

之前聊了 #10BASE2 以及 #10BASE5
有提到後來同軸電纜就慢慢退出區域網路接取標準
但是在廣域網路( #WAN ) 接取標準卻不是如此

在前幾篇就已經有象友提到，一些國家過去曾使用有線電視電纜進行網路接取。
確實，如：美國、中國，這樣地域廣大的國家，在過去因為有線電視作為基礎建設，有大量鋪設到許多人口非密集區；然而，這些地方如果要重新鋪設纜線作為網際網路傳輸，可能不敷成本。

#DOCSIS 就這樣出現了，嘗試透過已經存在的有線電視纜線 ( #Cable ) 來進行網際網路的傳送，應用在許多無法重新鋪設光纖線路的地區，而負責制定 DOCSIS 的組織 #CableLabs 也不斷的對 DOCSIS 進行提速，以目前最新的 4.0 版本也已經可以達到下載 10G 上傳 6G 的速度，與光纖常用的 #GPON 、 #EPON 相比也絲毫不遜色。

臺灣的有線電視業者也用 DOCSIS 提供有線網路接取服務，而目前政府的政策下逐步在更換為光纖，改為所有訊號都改為光纖傳送。

@jwildeboer @[email protected] If it were my decision, all lines would be symmetrical.
That being said shit like #xDSL and espechally #Vectoring and #DOCSIS are heavily asymetric.

Not mandating #FTTB & #FTTH coverage for every household as a must-provide utility at a fied rate like drinking water and electricity is the problem:

Cuz if it was my decision, every household would get two pairs of OS2 fiber laid and maybe some (x) #GPON in addition to that.
