ABSTRACT:
According to ITU-T Recommendation V. 34, the origination modem and the destination modem implement an original negotiation for determining a transmission rate of facsimile communication by executing a training independent of any controller. If the line therebetween is disconnected due to a communication error without establishment of the negotiation, the communication management information storage RAM13stores the communication management information. Thereafter, the CPU11eliminates the negotiation peculiar to the modems pursuant to V. 34 for redialing. The CPU11performs a negotiation for controlling the modems and selects a transmission mode corresponding to a communication capability of the destination facsimile based upon Recommendations V. 17, V. 29, and V. 27 ter.
