嗯...CM才開機三小時, 您就有這麼多 Ethernet error, 應該要檢查一下您的網路線, RJ45接頭, 或者是網路卡. 請您再嘗試一下: 將電腦及CM都關機, 然後CM開機, 待燈號正常後, 電腦開機, 進去看一下並紀錄上面的數字. 過了幾小時之後, 再記一下上面的數字, 看兩次紀錄是否會增加很多? 正常應該是 0, 或者兩次之間的差為 0, 頂多個位數到十位數. 若還是如上面那麼多, 建議換條網路線及網路卡試試看....

Downstream received signal power = 8.8 dBmV

此值在 -15~+15 之間都算正常...

QoS max upstream bandwidth = 128000 bps
QoS max downstream bandwidth = 2000000 bps

確認一下, 您租用的是 2M/128K 的頻寬?

SigQu: Signal to Noise Ratio = 34.1 dB

正常....

Upstream transmit signal power = 42.4 dBmV

此值在 55 以下都正常

Configuration filename = 1536-128-4.BIN

這是由頭端機房, 傳送給 CM 的組態檔名, 沒有什麼意義, 只是讓頭端機房人員辨識而已....

這跟頻寬沒關係嗎不是上行1536下行128_ip4個
也順便跟你說聲謝謝

檔名跟頻寬完全無關; 雖然有時機房人員會將檔名取得好像跟頻寬有關係, 但萬一日後變更頻寬, 卻沒有去改檔名的話, 也就變成沒有關聯了......

ps::我們有好幾家共用一條線路

CM 的品質上沒有什麼差別, 都很好.....但您要注意一下那幾個 Ethernet 開頭的數據, 如果有大量增加的趨勢, 則要考慮 RJ-45 這一段的連線品質....

喔了解謝謝你

訊號不錯唷~~

[freedom]

不好意思也可以幫我看一下我的資料嗎......?像我的Ethernet error值是不是也是太高.....訊號方面這樣也算很好嗎.....?
