Abstract
A terminal, such as a group 4 (G4) facsimile, coupled to an integrated services digital network has a function for setting up a confirmation call for automatically detecting a change of a different terminal, from a group 3 (G3) facsimile to a G4 facsimile. The G4 facsimile has a memory for memorizing information of a different terminal, such as, for example, a calling number, a short formed calling number under an abbreviated dialing mode, and a corresponding identification whether the different terminal conforms to a G3 or G4 facsimile procedure. The G4 facsimile sets up a confirmation call under the G4 facsimile procedure to confirm whether or not the different terminal has been updated to a G4 facsimile, only at a time of when the different terminal is identified as being conformable to the G3 facsimile procedure by the identification, and, optionally, when an arbitrary time period, which is memorized in the calling G4 facsimile, is exceeded. Upon succeeding in connecting to the different terminal by the confirmation call, the G4 facsimile carries on data transmission until completing the call process, and also updates the identification.
