Name MOD/DMTF Pin Number DIP24 1 PLCC28 1 MODEM or DMTF Operating Mode Selection. Also controls write operations to control registers (if MOD/DMTF = 0 and MC/BC = 0). Digital Control Input. In MODEM mode, it sets transmission mode to main or back channel. It also permits selection of dialing or control registers programming.
