CAPI
The driver software for the AVM ISDN-Controller B1
USB provides the industry standard application
programming interface COMMON ISDN API (CAPI) Versi-
on 2.0 (see Chapter 4). This interface, adopted by the
international standardization body ETSI, assures univer-
sal compatibility of ISDN applications and hardware for
ISDN data, fax and voice services.
IDM
The controller software for the AVM ISDN-Controllers
corresponds to the ISDN Driver Model (IDM). For further
informationen about the IDM architecture, please see
chapter 5.
Supported Operating Systems
The AVM ISDN-Controller B1 USB is available for the
Plug & Play operating systems Windows 98, Windows NT
5.0 (in beta test versions at the time of this printing) and
Windows 95 from release OSR 2.0 on with USB extensions
(OSR 2.1). The driver architecture complies with the
Microsoft Win32 Driver Model (WDM).
Several active AVM ISDN-Controllers can be easily
combined in one computer. Up to four active AVM ISDN-
Controllers can be operated at one time.
Installation of the ISDN-Controller hardware and software
completes the connection between the computer and the
ISDN line. The ISDN-Controller package also contains the
communications software suite FRITZ!32 and the AVM
ISDN Tools, a collection of CAPI-based utilities. Other CAPI
applications are available separately: just ask your dealer.
