The LaserWriter Select 360 and LaserWriter Pro 810 PostScript Fax Cartridges follows the CCITT (International Telephone and Telegraph Consultative Committee) Group III transmission standard of up to 9600bps.
Each time a facsimile device attempts to establish a connection, a training signal will be transmitted from the sending device to the receiving device. If impairments on the line cause the receiving device to get errors in the training signal, the receiving device will signal the transmitting device to repeat the training signal at a lower baud rate. This repeats until the receiving device receives an error-free training signal or, if the receiving device does not receive an error-free signal at every baud rate (9600bps, 7200bps, 4800bps and 2400bps), the transaction will be terminated.
Additional attempts to establish a connection will be attempted if you have requested so in the Fax Options dialog box: in the "Maximum number or retries" box, type the maximum number of times, 0 to 100, the fax software should redial the fax number of if it cannot connect.
Failures to connect at any baud rate due to impairments on the telephone line should be brought to your telephone service provider's attention.
