It used a data rate of 2 Mbit/s and carrier-sense multiple access with collision detection.
IBM's later Token Ring network emulated the NetBIOS application programming interface, and it lived on in many later systems.
Frequency-division multiplexing allowed the cable to be shared with other voice, video, and data traffic.
Later, in 1987 a much cheaper "baseband" version, also running at 2 Mbit/s connected computers in daisy-chain style using twisted-pair cables with 6P2C modular telephone connectors (often mistermed "RJ11").
[4] Interface cards had two 6P2C sockets for connecting to left and right neighbor nodes.
