[Asterisk-Users] Help Understanding ISDN Channels

[Francisco A. Lozano]

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...
