The AVM System Drivers
ISDN-Controller B1 PCI v4.0 – 14 AVM System Architecture 69
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
incorporation of V.42bis data compression and Group 3
Fax.
14.3 The AVM System Drivers
AVM provides two system drivers with similar capabilities:
the AVM ISDN CAPI Port Driver and the AVM NDIS WAN CAPI
Driver. Both drivers are controlled over Dial-Up Networking,
but use different mechanisms and interfaces and different
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 allow you to use CAPI-based ISDN
applications, alongside communications programs that do
not have built-in CAPI support, such as Windows’ Dial-Up
Networking.
The third AVM system driver, AVM ISDN TAPI Services, per-
mits the use of telephony applications with the ISDN-Con-
troller B1 PCI v4.0 in the Windows 7, Vista, XP, and 2000
operating systems.
The AVM system drivers are located in the PROGRAMS fold-
er on the installation CD. The latest versions are also avail-
able 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
also contains complete installation instructions.
