Mikey - that is a NVEI/Adapative/? issue... level 1 tech (NVEI) combined with levels 2-3... which we'll no doubt hear more about in the coming weeks and months. BER is a non-issue according to all that I've heard... NVEI is doing what they are doing in such a way that they have no more issues with noise than ADSL services have today. Said another way, BER is a non-issue, as noise is a non-issue, again relative to how it effects ADSl today. Granted, NVEI is dealing with much high data transfer rates, but as I said, noise is not an issue from what I have heard.
