我當時裝VDSL雙線

訊號品質好的要死
其實很多VDSL品質不良 都是死在住戶內的線路
老實講,一個看不懂VDSL訊號的和我說訊號好得要死,有點沒有說服力
我只能說你當初堅持錯方向了...
是我我會先準備一條CAT6A,請他幫我拉過去,然後讓他用綠色對或是橙色對(繳距密集的)
如果拿八對VDSL直接在DSLAM前面接數據機玩bonding(假設真有這個設備),那訊號也還可以,不會斷線,因為沒有足夠的距離去產生/吸收雜訊
你的狀況是根本不用bonding就可以跑單線100M,然後你現在跟我說你用了bonding訊號好得要死...
如果今天中華的VDSL設備,可以做到自動切換(遠端掛一台hypervisor去看用戶兩個port的值,判斷不穩就傳指令給VES1724去切換)
VDSL2 30a單線和VDSL 17a雙線,當雙線不穩自動把port profile切換成單線VDSL 30a,那我覺得可以試試看
但你今天搞一個具有redundant性質的機器,卻沒有failover,
一條不穩就一直重複斷線連接,一條斷線速度就剩下一半,還真是十分中華電信研究所的風格
你在這邊看這麼多,你不需要多占用一個VES1724的port,但中華無知讓你用了,你不主動讓出來沒關係,但也請不要鼓催這樣的行為,感謝
也许是一场难圆的梦
一场没有结局的梦
多少的笑语飞散在风中
又围绕在我耳边
