Abstract
For the purpose of efficiently determining the transmission capacity of a digital relay transmission path, adjusting the phase between commands and responses, and detecting faults, in the case in which a judgment is made that the image information transmission path capacity between communication apparatuses is smaller than or inferior to the performance of the communication apparatuses, when a training signal for the purpose of performing a circuit check is sent from a transmitting-side facsimile machine, the transmitting-side communication apparatus intentionally sends a failed training signal to the receiving-side communication apparatus, this giving notice of an abnormal termination, in response to which the transmitting-side facsimile machine performs a fallback operation so as to reduce the communication speed to a speed at which relaying is possible between the communication apparatuses before sending the image information.
