asterisk users - May 2005 - Help Understanding ISDN Channels

Hi:

The phone company here use Europe telephone system.
They offere ISDN lines with multiple channels,
starting with two and they add channels on demand. 

Am I write to understand ISDN of more like E1 or T1
line. If not, what's the difference.

The two-channel ISDN is called Basic Rate ISDN, and it's a smaller cheaper 
version of the Primary Rate ISDN (PRI).

With a BRI, you have two B-Channel (each 64kbps) and one D-Channel (16kbps). 
It's very common in Germany, Spain and other european countries, as reliable
low-cost low-bandwidth data solution or as a replacement for two POTS lines 
with much better voice quality and added services. You can even get a DSL 
over a BRI line...

I didn't know you could add more channels to a BRI... maybe what they 
offered you is just adding more BRI ISDNs, and not adding more channels to 
your BRI. Or maybe they're offering you a PRI with only two channels active 
and they activate it on-demand...
