Abstract
A communications link having a plurality of communication media is coupled between an originating facsimile machine and a terminating facsimile machine. The plurality of communication media includes a medium having a variable data transmission time followed serially by a media having a constant data transmission time. In the communication link, a transmission mode acceptance message is intercepted from an acceptance-transmitting one of the terminating and originating facsimile machines. The transmission mode acceptance message is modified to form a modified transmission mode acceptance message for increasing a maximum received data rate in the terminating facsimile machine relative to a transmit data rate in the originating facsimile machine. Thereafter, the modified transmission mode acceptance messages sent to an acceptance-receiving one of the terminating and originating facsimile machines, wherein the modified transmission mode acceptance message is part of a sequence of messages for negotiating transmitting and receiving modes in the originating and terminating facsimile machines, respectively, which sequence permits a maximum data rate in the medium having a constant data transmission time to exceed a maximum data rate in the medium having a variable data transmission time, thereby mitigating the effects of the variable time of transmission.
