One modem type for No. 18 is read out (step ■). Then, a check is made to see if the read modem type matches the modem type on the calling side (step 2). As a result, if they do not match (N), the next modem type is read from the main storage device 21 (step 2). Then, return to step (3) again to check for a match with the modem type of the caller. This process is repeated until the modem types match each other. If the modem types match (step ◯; Y), the receiving terminal 19 is connected via the trunk circuit from which the call was received and the corresponding modem.
