Image communication system having a function for shortening the pre-messaging procedure

摘要

A facsimile system includes a transmitting unit and a receiving unit which is connected to the transmitting unit by a telephone line. The facsimile system performs a pre-message procedure between the transmission unit and the receiving unit before the transmitting unit transmits the image information to the receiving unit. A part of the pre-message procedure is omitted on the basis of the condition of the transmitting unit and the receiving unit.
