Communication device connected to a first and a second communication networks

摘要

The present invention relates to a communication device connected to a first and a second communication networks. The communication device comprises a first and a second communication terminals respectively connected to a first and a second communication networks for respectively transmitting first and second format data; a data processing device for processing data; an input device for receiving input data from a user; an output device for transmitting output data to the user; a selecting device for the user to select one of the first and second communication terminals so as to generate a selecting signal based on the selection made by the user and output the selecting signal to the data processing device; and a determining device for determining whether the data processing device receives data from one of the first and the second communication terminals so as to generate a determining signal based on the determining result and output the determining signal to the data processing device.
