What happens when incompatible fax speeds attempt to communicate?

When incompatible fax speeds attempt to communicate, they typically will adjust to accommodate the slower speed. In fax communication, this process is designed to ensure successful transmission even when there are differences in device capabilities. The sending and receiving fax machines engage in a negotiation process at the start of the connection, where they determine the maximum speed that both machines can support.

If one fax machine operates at a higher speed than the other, the slower fax will dictate the transmission speed to maintain compatibility. This adaptive behavior enables the machines to successfully establish a connection and transmit the document, ensuring that the communication is effective despite the variation in speed capabilities.

In contrast, options like communication being rejected or the faster fax always winning do not reflect the typical behavior of fax machines, as they are built to facilitate communication rather than terminate it due to speed discrepancies. Syncing to the highest speed also misses the mark, as the adjustment always aligns to the slower device to maintain proper communication standards.
