2.2.06 Modem

The modem, located on the MCNT-150 board, modulates the data in the correct G3 (9.6, 7.2, 4.8,
or 2.4K bps) data rate that was determined during handshaking between the local machine and
the remote receiver. Modulation is the process of converting the digital output of the scanner into
an analog signal that can be transmitted over the telephone system.
