Abstract

An integral USB MODEM/USB LAN card peripheral comprises a first connector connected to a computer; a second connector connected to a telephone line; a third connector connected to LAN; a USB controller used to collect and dispatch internet data; wherein the USB controller has a micro-controller connected to a first memory, and a USB SIE (serial bus interface engine) connected between the first connector and the micro-controller. The micro-controller is connected to a MODEM module and an ether network media access controller through an internal bus, wherein the MODEM module is connected to the second connector for accessing Internet; and the ether network media access controller connected to the third connector through a physical layer for accessing LAN. Therefore, the present invention enables a computer to access LAN and Internet simultaneously; and the remote users to share compute resource with other users.
