ABSTRACT:
It is an object of this invention to provide a novel network interface system which is able to connect automatically to the respective network stations having different data transfer speeds, in order to avoid the above problems. According to this invention, there is provided a detector and a selector in the communication interface to automatically select the appropriate data transfer speed. In the above structure, the speed of communication data transferred by a network is one of two detected by the detector which is able to detect a transfer speed and provide outputs at a first level signal when the transfer speed is at one level and outputs a second level signal when it is at a second level. The selecting means selects the frequency to connect a network station in response to the signal output from the detector. As a result, users need not select the module by themselves, the system automatically select the module.
