SOLUTION: The communication equipment interrupts data communication with the slave unit only when receiving an external line call that is an individual call designating the slave unit and the designated slave unit is under data communication, allows the wireless individual call to reach the slave unit, allows the slave unit to make the external line speech, and sets up a data communication link when detecting the end of the external line speech and restarts the data communication.
