APPARATUS AND METHOD FOR DUAL LINK IN ETHERNET INTERFACE EQUIPMENT

摘要

PURPOSE: Apparatus and method for dual link in ethernet interface equipment are provided to remove an additional link setup process by applying the driving power to processors for dual physical layer. CONSTITUTION: Apparatus and method for dual link in ethernet interface equipment includes a first and a second signal buffer, a MAC layer processor, and a controller. The first and the second signal buffers(24-1,24-2) are used for turning on or off MII signals of dual physical layer processors(23-1,23-2) connected to an ethernet link. The MAC layer processor(25) is used for controlling output states of the MII signals of the first and the second signal buffers when troubles are generated from the ethernet link and the MAC layer processor. The controller(26) is used for controlling on-off states of the first and the second signal buffers.
