Dial-Out Setup for PPP-Client

FP Web-Server V2.11

 

 

"Additional User Modem init. command" in the tab "Dial-In (see page 127)" or/and "Dial-Out (see page 138)".

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:
