Abstract
A controllable configuration management (CFM) state machine user interface is disclosed for use in the physical layer controller of a station or concentrator capable or insertion into a data transmission network that is capable of operating substantially in accordance with the FDDI protocol. In one aspect of the invention, the physical layer controller includes a null configuration register, a join configuration register and a loop configuration register. The null configuration register is capable of storing information indicative of a desired configuration of the physical layer controller when the CFM state machine is in a null configuration. Similarly, the join and loop configuration register are capable of storing information indicative of desired configurations when the CFM state machine is in the join and loop configurations respectively.
