Abstract
There is disclosed a facsimile apparatus which transmits a predetermined signal, such as CNG signal, during pause periods succeeding the transmission of telephone number signals. This operation prevents the delay of CNG signal detection in case the receiving side has an automatic telephone/facsimile switching function, and also prevents the facsimile communication being erroneously cut off in case the pause period of the calling side eventually overlaps with the CNG detection period of the receiving side.
