Abstract

PURPOSE:To improve the convenience of a data terminal housed in a service synthetic digital network by providing a means which sets a calling to the data terminal in a terminal adaptor. CONSTITUTION:When a processing part 11 detects the calling of a telephone terminal 3 through an interface 13, a terminal adaptor 1 allows a signal tone generating part 15 to generate a call dial tone, and return it to the telephone terminal 3. When a digit button installed to the telephone terminal 3 is operated, and a preliminarily identified identification number for requiring a data calling setting is selected, after listening to this call originating sound, a corresponding PB signal is transmitted. The processing part 11 receives and analyzes the digit by the PB signal through a PB signal receiving part 16, recognizes that it is the calling setting request to a data terminal 2 connected with the same terminal adaptor 1, when it is identified as the identification number, and activates a data calling setting part 112. Thus, the calling setting request to the data terminal 2 can be attained by operating the telephone terminal 3, and it is not necessary to operate a key 17.
