skyeci has a point here which I didn't realise, I've only been connected to a Huawei cabinet but my Billion BiPAC 8800NL has worked very well on it. If you look at my most recent thread "Thank You Power Cut!", you'll see how stable it is under very low SNR Margin's.
Sorry to but in here, skyeci I sent you loads of messages, not sure if you're receiving them or not?
