Broadband "exchange-end" modem.

Do these even exist as standalone boxes?
Not generic "connect 2 of these to each end of a line", but one that
would work with a standard modem.

What do you mean? Why would a modem be in the exchange?

I assume he means the 'DSLAM' end ... if one (eg the council) were wanting
to link their existing buildings together in a 'star' network with their
own unit in the centre of the star, and a large (or small) number of
ADSL modem/routers spread around in each of the other buildings.

That's allow them to save if they already had a network of their own lines.
I suspect (to move back to Ian's query) that the 'mini DSLAM' would be the
thing ... <http://www.adslguide.org/newsarchive.asp?item=1059> ? Peter

I recommend them and save some cash.

With a guarantee allowing new users to migrate if they're unhappy!

They could install their own small DSLAM at the head office premises,
then use BT EPS9 lines to connect the remote ends, with a standard
ADSL modem installed at each one - but the remote ends must be
connected to the same telephone exchange as the head office.

you aren't allowed to do "reverse ADSL" ie put a DSLAM type modem on
your end of an exchange line as this would drown out your neighbours
weak downstream signal.

Thanks everyone for the comments.
Well, yes, I wasn't actually meaning to connect to BTs network, that'd
be silly, as it wouldn't actually (usually) work.

look for a DSLAM on Ebay ? I think it would be cheaper to use the "one
of these on each end of the line" types to be honest.

ZyXEL sell SDSL and VDSL kit which has a 'one line' device at the
'exchange' end..


For SDSL, which is certainly OK to use over a 'dark copper' circuit such
as what used to be called an EPS9 and is now called Baseband Standard,
investigate a pair of Prestige 791.

For VDSL, which is almost certainly outside the ANFP for the public
network, look at Prestige 841 and a Prestige 841C. You need one of each.
You probably can't use a P841 except with a P841C at the other end.
