6. Explanation of Communication and Compression Technologya. G3 Communication Signals (T. 30 Binary Process)For G3 Facsimile communication, this is the procedure for exchanging control signals between the sending and receivingmachines both before and after transmission of image signals.Control signals at 300 bps FSK are: 1850 Hz...0, 1650Hz...1.An example of a binary process in G3 communication is shown below.Explanation of SignalsControl signals are comprised mainly of 8-bit identification signals and the data signals added to them. Data signals areadded to DIS and DCS signals.Signal.....DIS (Digital Identification Signal)Identification Signal Format.....00000001Function:Notifies the capacity of the receiving unit. The added data signals are as follows.Signal.....DCS (Digital Command Signal)Identification Signal Format.....X1000001Example (Some models do not support the following items.):Bit No. DIS/DTC DCS1 Transmitter --- T.2 operation2 Receiver --- T.2 operation Receiver --- T.2 operation3 T.2 IOC = 176 T.2 IOC = 1764 Transmitter --- T.3 operation5 Receiver --- T.3 operation Receiver --- T.3 operation6 Reserved for future T.3 operation features142KX-FP362BX
