The AVM System Drivers
ISDN-Controller C2 – 8 AVM System Architecture 45
One of the most important features the IDM enables is the
coupling of existing communication components such as
RAS with CAPI-based hardware. This connection is realized
by the AVM system drivers such as the AVM CAPI Port Driver
or the AVM NDIS WAN CAPI Driver.
This architecture permits the simultaneous use of CAPI, mo-
dem and networking applications over ISDN. Most impor-
tantly, it also permits the definition and implementation of
new, extended capabilities. Examples to date include the in-
corporation of V.42bis data compression and Group 3 Fax.
8.3 The AVM System Drivers
AVM provides two system drivers for Windows with similar
capabilities: the AVM ISDN CAPI Port Driver and the AVM
NDIS WAN CAPI Driver. Both drivers are controlled over 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 ISDN CAPI Port Driver and the NDIS WAN CAPI Driver can
be installed and operated on the same computer if desired.
The AVM system drivers make it possible to use CAPI-based
ISDN applications, such as Windows’ Dial-Up Networking,
alongside communications programs that do not have built-
in CAPI support.
The third AVM system driver, AVM ISDN TAPI Services for CA-
PI, permits the use of telephony applications with the AVM
ISDN-Controller C2 in the Windows operating system.
The AVM system drivers are located on the installation CD in
the PROGRAMS\<DRIVER>\<DRIVER.OPERATING SYSTEM> fold-
er. The latest versions are also available for downloading
from the AVM Data Call Center or from AVM’s FTP server on
the Internet.
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.
