Similar idea. BT had a few variants - bog-standard 64Kbps boxes which worked on dry copper - that was Kilonstream, or a channelised variant - Kilostream-N - to work with PSTN technology, so you got N channels of 64Kb/sec out of a 2Mb bearer - up to 30, when you had the option of taking the full 32 unchannelised (Megastream!) - depending on what you were after. (or could afford!) Telewest would do 128Kb/sec on dry copper if you asked them.
There were the mainstay of the ISP business in the mid 90's. I was working for one then and we had kilostream & megastream lines going all over the country from our POPs in Bristol, London, B'Ham & Manchester...
BT at one point would supply dry copper pairs if you knew what to ask for - and there was a range of 2Mb baseband modems for these at the time - they're still avalable, but I doubt you can get a EPS8 or EPS9 line from BT anymore... (We managed to get one in Buckfastleigh 7 years ago though, and used a pair of expen$ive cisco baseband modems on it... Connected to the primary schools connection to SWGFL - the horrors :)
