Fiber Distributed Data Interface (FDDI) Configuration Management (CMF) State Machine User Interface

摘要

Controllable Configuration Management (CFM) The state machine user interface is used to enable a station or concentrator that can be inserted into a data transmission network that can actually operate in accordance with the Fiber Distributed Data Interface (FDD1) /RTI In one embodiment of the invention, the physical layer controller includes a blank configuration register, a join configuration register, and a loop configuration register. Space Configuration Register CFM State When the machine is in the blank configuration, information indicating the desired configuration of the physical layer controller can be stored. Similarly, the join and loop configuration registers can store information indicating a preferred configuration when the CFM state machine is in a join and loop configuration, respectively.
