CONSTITUTION:In an exchange system applying data communication between a terminal equipment and a common controller 16 of an exchange, plural MODEMs 21, 22 are provided correspondingly to plural extensions. In applying exchange connection to the terminal equipment and the common controller 16, based on any of extension numbers X, Y assigned to the MODEMs 21, 22, the common controller 16 is connected to a terminal equipment via any of the MODEMs 21, 22. Thus, it is not required to visit the exchange to select the MODEM and it is possible to select it externally.
