What Rod actually said was "strictly speaking ISDN is DSL too". That's a 
direct quote.
It's not. ISDN is a network (hence the N) which incorporates a line 
technology.
DSL is purely a line technology. The network is an entireley separate 
entity.

My point regarding the D for Digital is that if Rod is claiming that ISDN is 
a form of DSL as a result of its ability to transfer digital data, the same 
could be said for dialup modems. They both do exactly the same thing, just 
using different D-A encoding techniques.

DSL refers to a specific means of transferring data using specific 
'channels' of available bandwidth that are not used for transmission of 
voice. ISDN doesn't do this. It doesn't split it's bandwidth into channels 
and covers the VF spectrum as well.

He's wrong.
