no BY is cable only, There ok i suppose, but the upstream speeds are a alot slower than dsl, they seem to give full concentration on downstream speeds and not worry about upstream, look at bulldog DSL 8mb Down 400k up, BY 10mb Down 300k Up.. i think it has something to do with the copper in phonelines why DSL uploads are faster
and i also find (so far) BY to be not very reliable at all, in the few weeks ive been on with them, i have had 3 times where i cant connect, cable light just blinking, and a phone call to them just gets me "there is an outage in the area, and you will be back on asap" which the 3rd time (yesterday in fact) took me untill 7am this morning to connect again
alltho, from what i read on forums, cable is alot more relible than DSL, all i say to that is, i feel so so sorry for people on DSL
