No. There is a centre core and an earth around that. That is a genuine broad band connection, as it has width as well as serial data.
Having said the above, I can see where other posters are coming from. But I have always seen a twisted pair as a serial link.

Guys, as interesting as it is, when was the last time any of you DIY'd some ADSL exchange equipment ;-)
Take it to alt.sad.nerds.broadband.excellent.service.checker.which.was.pointed.out.b y.the.philospher or something :-)
Twisted pair can carry broadband in any sense of the word, so perhaps your view needs a little tweaking!
I was doing things with some earlier this week.
So there.

They use 75khz deviation plus the digital sub-carriers and stereo pilot tone etc. Takes a bit above 100khz
Last Sunday.
Maximum allowed deviation is 75 KHz. This /includes/ stereo pilot and RDS modulation & anything else encoded. Bandwidth is in the region of 200KHz.
At least 250Khz for any fidelity, and 400 KHZ low phase delay is as good as it gets. Butr isn;t good enough for todays crowded spectrum ... channels are spaced as low as 100KHz overall, though adjacent transmitters are suppoosed to not be closer than 300KHz IIRC.
Its not maxiumum allowable. Its the normal deviation for 'full audio'. In practice it goes a lot higher..and the full spectrum even at the rated deviation is far higher..sidebands etc.
