I use an Intertex router (
www.intertex.se) & subscribe to a very useful customer run support site. A user asked about the ADSL Frequency diagram that is in the user interface of the combined ADSL modem/routers. This
link takes you to the answer provided by Intertex's Development Manager.
For those interested in such things, it's a nice non-techie explanation of how ADSL manages to get all that data down an ancient bit of copper wire.
P.S. If you're into VoIP, these routers are the dogs danglies. Not cheap, though.
