ISDN and ADSL
Posted by Trevor Appleton on March 25th, 2005


A recent poster suggested that if you are on ISDN and your exchange upgrades
to ADSL then you will have to loose ISDN to get ADSL.

I certainly hope not as I need ISDN to broadcast from home on BBC Radio.
Surely this won't penalise me against going broadband?

you just have to have an analogue line for ADSL, this may mean getting
an extra line in your case. You don't have to "give up ISDN" but you
will pay a tenner a month or whatever more for the line. OTOH you may
already have a second line that is analogue and can use that.

It is true that BT [unlike some other European PTTs] will not supply
ADSL over ISDN lines.

You do not necessarily have to relinquish ISDN, however you will then
need to do what many of us have done - purchase an extra analogue PSTN
line just for ADSL provision.

That is correct - you have to let the ISDN loose!

More seriously...in this country the two are incompatible. You can't
have both on the same line. I solved that by getting a second line...!

Yes already have a normal line as well. Thanks for the info.

The frequency range that's used by ISDN in the UK overlaps a tiny bit
at its top end with the bottom end of the frequency range used by
ADSL, which is why they can't run on the same line.
