ISDN B-Channel

The ISDN B-Channel, or Bearer Channel, is primarily used for voice and data transmission in Integrated Services Digital Network (ISDN) services.

It offers a bandwidth of 64 Kbps and is responsible for carrying user data.

Each ISDN connection typically provides multiple B-Channels, allowing for simultaneous data and voice communications.
