10Broad36 (10 Mbps, Broadband, 3600 meters)

Intended for applications that require only one information-bearing channel, perhaps for voice or data transmission, 1B+D supports one bearer (B) channel and one data (D) channel. The D channel is designated for signalling and control purposes, but also can be used for low-speed packet data applications such as transaction processing, credit card verification, and telemetry. See also 0B+D, BRI, and ISDN.
