Multifunctional interface circuit and multifunctional interface realization mode

Abstract

The invention relates to a multifunctional interface circuit and a multifunctional interface realization mode. The circuit comprises a processor and at least two switch chips; the processor comprisesa media independent interface and multiple serial management interfaces; each switch chip comprises a media independent interface, a serial management interface and multiple general data interfaces; each switch chip performs cascading through the general data interface, so that a switch chip cascading system is formed; the serial management interface of each switch chip in the cascading system isconnected with that of the processor in a one-to-one correspondence manner; the media independent interface of any switch chip in the cascading system is connected with that of the processor; and theprocessor establishes communication with each switch chip, performs parameter setting on the residual media independent interface and serial management interface of each switch chip, and configures the media independent interface and the serial management interface as a multifunctional interface corresponding to parameters. The circuit can quickly generate multiple multifunctional interfaces.

Description

technical field [0001] The invention relates to the communication field, in particular to a multifunctional interface circuit and a multifunctional interface realization method. Background technique [0002] In the field of communication, wired network transmission is a very important communication method, which is widely used in indoor and outdoor short-distance transmission because of its high transmission stability and strong anti-interference ability. In wired network transmission, it is necessary to connect information transmission devices with connecting wires (such as coaxial cables, twisted-pair wires, optical fibers, etc.), and the transmission modes match each other. There are various forms of existing wired network transmission (for example, IP electrical port, optical fiber port, etc.), however, most devices can only support one or two network transmission methods. When the interface methods of the two devices do not match, Information exchange will not be possi...
