2.7 Placing a CSD Data call (not GPRS)<br />
Before a data call can be placed, it is recommended to check if the mobile is registered on a network<br />
(see par. 2.5.3.1) and if the signal strength is enough to ensure that a call can be made (see par. 0).<br />
2.7.1 Data call device set up<br />
2.7.1.1 Set the device in data mode<br />
• Send command AT+FCLASS=0<br />
• wait for OK response<br />
TIP: The +FCLASS setting is maintained in memory, so there's no need to repeat this command<br />
if +FCLASS setting is not changed.<br />
2.7.1.2 Set the desired modulation and speed for the connection<br />
The data connection can be made using different modulations at different speeds.<br />
This connection mode can be selected with the command +CBST. The syntax for the command is:<br />
AT+CBST=,0,<br />
These parameters can be selected as seen in the table:<br />
