看圖只知道下載的snr是257.6過高，有哪位知道問題所在的可能性呢

電話線可能有T接干擾到噢

我也這樣想，打算晚點從電信機房開始查線，別是外包沒把線打好吧，
最近真得是被搞翻了，六天總計才異動好11路，目前為止有的還有些小問題，等異動完再來算總帳，不過千萬秋後算帳，我會死得很難看:sleep:

最近中華電信人忙翻了，辛苦了。
樓上的也是。

acion兄可否提供數據機型號與韌體版本，謝謝。

要補充說明一些
8天的時間，小弟總共花了近60個小時，只升速11路，多半的時間都在跟機房溝通與報修中，但實際上都是外包在的時候處理完，只有這一路有後續的問題
實際上這兩三年，小弟每次異動幾乎都會遇到外包到了現場，機房還未完成設定，釘線釘假的???
今天去電信機房自己重打線所獲得的P874數據如下：

但是上傳最高只有不到2M，我想瞬段主因應該在於上傳不足(流量一直不大)

更令人生氣的是，客服跟我說DSLAM機房今天全部休假沒人，
！！！中華電信DSLAM機房逢一般假日就全部打烊！！！

老共，你看到了嗎??這算不算是情資呢
我可以申請電信情報費嗎??

再補充一點，星期六中午報修一路升速中的線路(還未通知施工，這是第三路未通知就長時間斷線)，機房處理到下班時間就說等星期一吧

奇怪，只有我這麼衰嗎??

假日就沒人的話，
升速作業不就停擺了。

orz....

固6 50M/5M瞬斷的慘況(遠端==>>GATEWAY==>>該線路IP，到GATEWAY正常)
