A facsimile interface apparatus is connected between facsimile terminals communicating via a satellite. The interface apparatus converts a conventional facsimile signal to a signal suitable for transmission to the satellite. However, the interface apparatus and the satellite may incur a long delay such that the calling facsimile terminal repeats a transmitted signal while the response to that signal is being received over the satellite. To overcome this problem, the facsimile interface apparatus connected to the calling terminal sends, after a period t1, a holding signal to the calling terminal, to prevent the calling terminal from repeating the transmitted signal. After a further period t2, the interface apparatus sends a command repeat signal to the calling terminal, so that the transmitted signal is repeated if the called terminal has not transmitted a response.
