4 ISDN and GSM Operation
In using application software with the AVM Mobile ISDN-
Controller M2, there are a few minor differences
depending on whether the Controller is connected to
ISDN or to GSM. These differences are due mainly to the
V.110 ISDN protocol used by GSM network operators at
the gateway from GSM to ISDN.
The following instructions refer primarily to the application
packages included with the Controller, FRITZ! and
FRITZ!GSM.
4.1 ISDN Operation
If you want to use the communications software supplied
in ISDN operation, then install FRITZ!. The installation
and use of the FRITZ! software for ISDN connections is
described in detail in the enclosed “FRITZ!32” manual.
The AVM ISDN CAPI Port Driver
The AVM ISDN CAPI Port Driver provides “virtual
modem” entries which can be used in Windows’ Dial-Up
Networking and other applications for connections to the
Internet and to on-line services. From a technical point of
view, the CAPI Port Driver mediates between Windows’
Unimodem/VCOMM architecture and the Common ISDN
API 2.0 (CAPI) interface. This application interface is
provided by the AVM Mobile ISDN-Controller M2’s
driver.
The AVM ISDN CAPI Port Driver can be installed
automatically together with the FRITZ! or FRITZ!GSM
communications software. For further information on
using the AVM ISDN CAPI Port Driver and the virtual
CAPI modems, please see the file Capiport.hlp in the
Programs/Capiport.NT or Capiport.W95 folder on the
CD-ROM.
