What is the 16 kbps digital line used for in an isdn connection?

Answer

In a Basic Rate Interface (BRI) line, there are 2 64 kbps lines (called the B-Channels) for voice and data, but there is also a 16 kbps line )called the D-Channel) that is used for connecting between your different pieces or hardware and the network. In a Primary Rate Interface (PRI), there are 23 B-Channel lines and one 64 kbps D-Channel line and in Europe there are lines that support 30 B-Channels and one D-Channel.
