A fax system employed in a packet switching network environment for use by fax users for transmission of fax information includes a network device coupled, through a network interface, to one or more communications devices for transmitting a processed fax message through the network interface to one or more of the communications devices, each of the communications devices being capable of receiving fax information and having a predetermined minimum scan line time therefor. Prior to the transmission of the processed fax message, the network interface being adapted to transfer a first frame from the communications devices to the network device, said first frame for indicating whether or not a particular communications device supports Error Correction Mode (ECM) and if the particular communications device supports ECM, the network device for transmitting fax information through the network interface to the particular communications device using approximately zero minimum scan line time, wherein fax information is transmitted at a fast speed through the use of zero minimum scan line time thereby decreasing costs to the users of the fax system.
