Embodiment Construction

[0026] The basic idea of ​​the present invention is to provide a switcher, one end of the switcher is connected to the RJ45 socket, and the other end can be switched between the local area network bus (LAN Bus) and the modem bus (Modem Bus), thereby the phone can be connected through the RJ45 socket Dial-up Internet access and broadband Internet access by connecting ordinary network cables.

[0027] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] see figure 1 , is a schematic structural diagram of the data transmission circuit provided by the present invention. The data transmission circuit includes an RJ45 socket, a switch (Switch), a LAN bus and a modem bus. The RJ45 socket is used as an interface, which can accept the insertion of RJ45 plugs or other special plugs, so as to exchange data with the outside. The LAN bus is used to transfer data to / from the LAN chip, and the modem bus is...

Abstract

The invention provides a data transmission circuit, a communication device and a switch device. The data transmission circuit comprises a RJ45 socket, an LAN bus, a Modem bus and a switcher, wherein one end of the switcher is connected with the RJ45 socket while the other end thereof is connected with the LAN bus and the Modem bus for switching between the LAN bus and the Modem bus. By utilizing the communication device of the data transmission circuit, the functions such as a dial-up internet access can be realized through the RJ45 socket and a telephone wire, which results in a convenient design of an interface of the device without using an RJ11 socket.

Description

technical field [0001] The invention relates to communication technology, in particular to a data transmission circuit, communication equipment and switching device. Background technique [0002] At present, the design of notebook computers (laptop PCs) is developing toward miniaturization and thinning. The side area of ​​notebooks is getting smaller and smaller, but there are more and more peripheral interfaces that need to be placed on the sides. How to reasonably place the peripheral interface has become a problem that is often encountered in the design of notebook computers. If the peripheral interfaces of the notebook can be effectively utilized and reduced, the industrial design (ID, Industry Design) and mechanical design (Mechanical Design) of the notebook can be more diversified, and the arrangement of the peripheral interfaces of the motherboard can be made easier and more flexible. [0003] Dial-up Internet access and broadband Internet access are two functions fr...
