Title: A MEANS AND CONTROL METHOD FOR ADAPTING DIFFERENT MEDIA OF TRANSMISSION LINK OF NETWORK ON PHYSICAL LAYER.
Abstract:
A means for adapting different media of transmission link of network on physical layer, includes at least : a common interface, for connecting a interface of media access control (MAC) module ; more than one channels of different media ; a switch and control means , as a part of physical encoding sub-layer, for controlling auto-switch between channels of different media. FIFO synchronization for connecting the different media, are performed on the physical encoding sub-layer. It further includes : a detect and control means, for detecting state information of the channels and switching the channels according the state information; and a flow control means, outputing to a management interface of the switch and control means. The present invention can be applied to broadband computer network and the field of data communication to convenience network users, and the users are capable of flexibly selecting the type of physical media according their own requirement and conditions, and meanwhile the reliability of key-link in the network is ensured.
