Abstract: A data interface circuit for portable radio terminal equipment having wire and radio data communication functions, thereby capable of being applied to a variety of communication systems. For a communication using a radio network, the signal type is changed from a differential-ended-signal (DES) type highly influenced by noise to a single-ended-signal (SES) type hardly influenced by noise by an operation of the radio interface unit, thereby enabling the redundancy to noise to be increased. Furthermore, it is possible to provide various audio services by the audio signal processing control unit.
