Network embedded data switching distribution frame device and implementation method

The invention discloses a device of a network embedded data switching distribution frame, which comprises data interface devices, common paths and preset paths, and is respectively provided with more than two data interface devices, more than two common paths and more than two preset paths, the data interface devices, the common channels and the preset channels are all embedded in one side of the host, each data interface device is connected with one common channel and one preset channel, and all the common channels are not connected with one another. According to the invention, when signal data transmission is congested or lines need to be switched in a weak current system, an A group of relay switches on a common path which needs to be interrupted are controlled to be interrupted through an instruction, and a B group of relay switches on a preset path which is prepared to be switched on are controlled to be switched on, so that automatic line switching of corresponding data interface equipment is controlled
