Hi again MC,
Yes the 2700 is BT's business router and is only available from amazon or e-bay. It is rather tricky to set up but there are instructions available at :-
http://bt2700hgv.tripod.com/002.htmProvided you have a standard ADSL signal then the 2wire will work just as any ADSL modem will but, as far as I'm aware, is not future-proof for VDSL2 solutions.
I have conducted a number of practical experiments and have found nothing better for long and noisy lines.
In particular they seem much better at holding a poor signal and recovering to the same speed after a significant event.
You can look at some of our somewhat parochial adventures here:-
http://www.ewhurst-broadband.org.uk/?cat=4I am not aware if anybody has published actual research of the differences between modems and in any case I believe the 2Wire use a bespoke chip set.
I believe Kitz's opinion is that different modems can work better in some circumstances than others so you have to experiment.
If BT has announced that your exchange is to be FTTC enabled you might just find a BT Openreach engineer with a list of the cabinets they propose to upgrade.
N.B. there is no guarantee that every cabinet will be upgraded. Otherwise, unless you get involved in a brouhaha such as that at Erbistock I think you will find that BT will not disclose their future plans.
Kind regards,
Walter
EDIT One other caution !!!!!! NEVER tell a BT domestic help desk person that you're using a 2Wire as the auto-pilot cuts in and they will transfer you to the BT Business call centre, one section of which is in Dundee.
(They tend to be more experienced people who will attempt engineering diagnosis rather than reading from an Indian script.)
HOWEVER they are powerless to help domestic users as they have no access at all to any details of your connection except to say it is not a business line.
To a lesser extent some other ISPs may not know too much about the 2 Wire as it's restricted by BT and is not supposed to be available to anybody in the UK other than BT Business subscribers. If you are familiar with the interface it's not too difficult to tell call centre staff the parameters they need to know.
