Abstract
Official abstract text for this publication.
A method of performing handshaking between fax machines on the basis of T.30 protocol includes transmitting information on a first data rate selected to transmit a fax document to a receiving-side fax machine, transmitting a plurality of frames including bit strings predefined to test data transmission/reception at the first data rate prior to transmitting the fax document to the receiving-side fax machine, and receiving a message informing success or failure of the test. The transmitting of the frames includes determining a time duration of the transmitting the frames based on at least one of a TCF flag value and the first data rate.
First claim
