CenturyLink Basic Rate Interface (BRI): Single Line Service is a platform-based, switched digital service based on ISDN, a digital network architecture that provides both a voice connection and a high- or low-speed data connection simultaneously over existing telephone lines (i.e. twisted pair). CenturyLink BRI has a transmission rate of 144 Kbps divided into three channels. There are two B channels capable of 64 Kbps each and one D channel capable of 16 Kbps. Since the D channel is used for signaling, the B channels have a higher transmission rate than is currently available on a regular voice channel. Each B channel is capable of circuit-switched voice, circuit-switched data, or packet-switched data (individual case basis only). The D channel is capable of Q.931 or X.25 protocol signaling or X.25 packet-switched data.
