Method for decreasing facsimile delay

Abstract

The method comprises: when a fax terminal calls another fax terminal, two fax terminals are connected only using a digital transmission way, not a modem connection way, so as to reduce the time delay of fax and improve the success rate of fax transmission.

Description

technical field [0001] The invention relates to facsimile technology, in particular to a method for reducing facsimile delay. Background technique [0002] Facsimile communication is a communication method that uses scanning and photoelectric conversion technology to send static images such as text, pictures, and photos from the source to the receiving end through wired or wireless channels, and reproduce the still images at the receiving end. Since the 1970s, due to the opening of the file fax service on the Public Switched Telephone Network (PSTN), fax communication has been vigorously developed and has become one of the means for people to transmit information. [0003] see figure 1 As shown in the fax network diagram, the fax terminal on the PSTN side is directly connected to the PSTN network, and negotiates and communicates with other fax terminals through the PSTN network; the fax terminal on the mobile side is connected to the On the mobile network, negotiate and co...

Problems solved by technology

Since the existing fax protocol is a half-duplex protocol, the fax terminal cannot send and receive BCS frames at the same time. Therefore, if the fax delay is too large, it is easy to cause a collision between the retransmitted BCS frame and the response BCS frame, resulting in fax failure.
