[Asterisk-Users] Help Understanding ISDN Channels
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... ----- Original Message ----- From: "chawki hammoud" <cyhammoud@yahoo.com> To: <Asterisk-Users@lists.digium.com> Sent: Saturday, May 21, 2005 12:14 PM Subject: [Asterisk-Users] 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.
