The AVM System Drivers
30 Controller C4 – 6 AVM System Architecture
This architecture permits the simultaneous use of CAPI, mo-
dem and networking applications over ISDN. Most im-
portantly, it also permits the definition and implementation
of new, extended capabilities. Examples to date include the
incorporation of V.42bis data compression and Group 3 Fax.
6.3 The AVM System Drivers
AVM provides two communication models for Windows,
equipped with similar capabilities: the AVM ISDN CAPI Port
Driver and the AVM NDIS WAN CAPI Driver. Both of these
drivers are controlled through Dial-Up Networking, although
they use different interfaces and protocols in the operating
system. These drivers achieve the same transfer speeds in
data communications.
The AVM ISDN CAPI Port Driver and the AVM NDIS WAN CAPI
Driver can be installed and operated on the same computer if
desired.
The AVM system drivers make it possible to use communica-
tion programs that do not incorporate CAPI support, such as
Windows’ Dial-Up Networking, concurrently with CAPI-based
ISDN software.
The third AVM system driver, AVM ISDN TAPI Services for
CAPI, permits the use of telephony applications with the
AVM ISDN-Controller C4 in the Windows operating system.
The AVM system drivers are found on the installation CD-
ROM. The latest versions are also available for downloading
from the AVM Data Call Center or from AVM’s FTP server in
the Internet (
ftp.avm.de or www.avm.de).
For a detailed description of each driver’s functions, please
see the Help file in the corresponding folder. The Help file al-
so contains complete installation instructions.
