"Dial-Out (see page

10.1.4 GPRS Internet Connections
In general a GPRS connection is set up in the same way as a regular PPP dial-up (see page
138) connection. The exceptions are:
• The telephone number of the Internet dial-up provider is replaced by *99***1#
• Only a connection to the Internet is possible
• The data amount transferred is billed (not the online time as with GSM)
• A special +CGDCONT parameter (provider-dependent) is needed to set up the module
We have tested the Siemens MC35 and the Wavecom Fastrack GPRS units. Both are to be set
up in a similar way. For the Siemens MC35 the two parameters +CGDCONT and +CGQREQ
are automatically set up with the SIM card. For the Wavecom Fastrack you have to initialize it
once manually. Use a terminal with 9600 8n1 and enter AT+CPIN=xxxx to log onto the network.
Then enter:
1. AT+CGQREQ=1,3,4,3,0,0 (Provider-dependent)
2. AT+CGDCONT=1,"IP","Internet.t-d1.de" (Provider-dependent)
3. AT+IPR=0 (Automatic baud rate detection)
4. AT+IFC=2,2 (RTS/CTS handshake)
5. AT&W
In this example the parameters for the German GPRS provider "T-Mobile" were used. Please
ask your GPRS provider for the correct parameters.
The ‘Modem init command’ in the “Dial-Out” section can also be used for additional modem
setup commands such as AT+CGDCONT=. Or it can be used for the PIN code entry. The AT
commands listed here are transferred to the modem shortly before the dial-up command for the
Internet.
For GPRS "dial-out" connection, enable the PPP-Server function (see page
127) in the "Dial-In"
section. The ‘Modem init command’ in the “Dial-In” section can be used for additional modem
setup commands. Maybe the AT+CGDCONT command can be entered here.
For continuous Internet connections via GPRS, enable "periodic communication test function".
For GPRS connection, hardware version 1.0 should not be used.
For details, refer to the online help under 'Example12', which demonstrates how to set up and
test continuous GPRS Internet connection. .
10.1.5 When Using ISDN Adapters
The PPP-Server (dial-in) and PPP-Client (dial-out) of the FP Web-Server can also handle ISDN
modem adapters for remote connections. Following are some hints to use the FP ISDN 64k
adapter from PEW Germany:
