Abstract

PURPOSE:To reduce the number of keys, by assigning plural alphabets to numeric keys for 0-9 and by depressing a numeric key, which indicates the order of alphabetic characters, after depression of a numeric key to designate one alphabetic character. CONSTITUTION:A line designation indicating key CG, numeric keys for 0- 9, and a completing key ST are provided on a panel surface 9 provided in a test board 8, and plural alphabetci characters are assigned to numeric keys respectively. In case of the test for a trunk circuit 5, when the maintensance engineer has depressed the key CG, information is transferred to a processing device 2 through a test board control device 4. When he depresses numeric keys twice next, the processing device discriminates plural characters, which are assigned to the key, by the first depression and discriminates one character by the second depression. Further, when he depresses a numeric key and the key ST, the trunk circuit 5 is discriminated and the trunk circuit 5 is connected to the test board 8 through a channel driving device 3 and a trunk circuit 6.
