Short for Delta-channel, the channel in an ISDN connection that carries control and signaling information. Basic Rate ISDN (BRI) service consists of two 64 Kbps B-channels, and one D-channel for transmitting control information. Primary ISDN service consists of 23 B-channels (in the U.S.) or 30 B-channels (in Europe).
