<p>PURPOSE: To obtain an integrated circuit card which is equipped with a channel interface part for interfacing with a channel prepared for an information processor and alters the communication interface function according to corresponding communication media. CONSTITUTION: A PC card type communication control board 1a consists of a channel interface block card 10, an ISDN interface block card 13a which is connected to a detachable connector 16b, and a CSMA/CD interface block card 13b which is connected to a detachable connector 16c. A system 50 can send and receive data by using an ISDN line or CSMA/CD line. Further, the system 50 can operate as a router to send data to another system, and thus the integrated circuit card is constituted.</p> |
