Billing Protection
Connection Speeds
Automode
When the modem goes off-hook to answer an incoming call, both transmission and
reception of data are prevented for 2 seconds (data modem) or 4 seconds (fax adaptive
answer) to allow transmission of the billing tone signal.
The modem functions as a data modem when the +FCLASS=0 command is active.
Line connection can be selected using the +MS command. The +MS command selects
modulation, enables/disables automode, and selects minimum and maximum line speeds
(Table 2-1).
Automode detection can be enabled by the +MS command to allow the modem to
connect to a remote modem in accordance with draft PN-3320 for V.34 (Table 2-1).
