How Fax Works? (Function of Frame Protocol)

 The communication between two fax machines is as follows:

1.            The transmitter calls the receiving fax machine. The transmitter will generate the dialing signal and then continuously send out a CNG tone which is used to signal an auto receive fax machine that another fax is making the call. This CNG tone is also used with allot of line sharing devices today.

2.            The phone line on the receiving side will ring and the receiving fax will pick up the line and send out a CED tone. This tone only tells the transmitter that it has connected to a fax machine.

3.            The receiving fax then sends out a PREAMBLE signal. This signal is a series of flags that are sent out to condition the phone line and to synchronize the two modems. A PREAMBLE will be generated just before any binary information is sent over the phone line.
