Abstract
A method and apparatus for a node being inserted into a token ring local area network to sense the data transmission speed of the token ring LAN and automatically setting the data transmission speed of the node to match the data transmission speed of the token ring LAN. The token ring LAN may operate at either 4 megabits per second or 16 megabits per second. The node recovers data transmitted on the token ring, and determines, based thereon, the speed of the data transmission and configures the speed at which the node transmits and receives data to/from the token ring network accordingly.
