Connections to ISDN TAs
Alternatively, the settings can be entered or modified using the terminal pro-
gram.
To call an ISDN TA it is necessary to set the
ISDN protocol V.110. While doing so it must
be observed that the remote terminal has to
work with the same protocol as well.
AT+CBST=<n>
E.g.: The protocol V.110 with a data rate of
9600 baud.
AT+CBST=71

Direct GPRS Connection via PPP
When the GPRS functionality of the built-in GPRS/GSM/EDGE Engine of the INSYS
GPRS 5.1 serial is used directly, the INSYS GPRS 5.1 serial provides only raw PPP da-
ta. In this case, the application must perform the required protocol stacks (PPP,
TCP/IP) for the application. In this mode, the TCP/IP stack of the INSYS GPRS 5.1
serial is not active.
Example: Connection via the RDT network of a PC.
The INSYS GPRS 5.1 serial is the PPP server in this mode.
The direct utilization of GPR connections via PPP is not possible if the device is in
active TCP Listen mode.
5.4.1
GPRS APN (PDP context)
E.g.: The Vodafone APN address is
WEB.vodafone.DE.
AT+CGDCONT=1,IP,”WEB
.vodafone.DE”
There is basically the option to define several PDP contexts. This one is stored as
context "1".
Note
The PDP context can not be stored permanently; it must be re-
entered every time the device is restarted,
