Dear Developer!

The AVM  ISDN-Controller B1 is one of the most powerful and popular
active ISDN-Controllers on the market today. The B1 offers a stable
platform for professional users, who require performance, power
and reliability. Currently AVM provides COMMON-ISDN-API 2.0 drivers for DOS,
Windows 3.x/WfW, Windows 95/98, Windows NT, Windows 2000, Novell NetWare 
3.x/4.x/5.x, OS/2 and LINUX. 
The flexible hardware architecture of the B1 controller makes developing
drivers for other operating systems easy. The complete ISDN-protocol software
stack is executed "on board" the B1 controller, via a downloadable file. This
of course means that the same protocol stack is used, regardless of the
operating system. This approved ISDN protocol stack, guarantees ISDN
communication of the very highest standard, the hallmark of all AVM products,
in every environment.
AVM is continually developing and enhancing these drivers in accordance with
the CAPI guidelines. The newest drivers are distributed via the Internet
and AVMs Data Call Center (ADC). This on-going process reduces the costs
of developing a new driver, making it necessary to develop only the operating
system dependent modules. The complete handling of the ISDN-line is performed
by the driver on the controller.
AVM provides a development kit (Low Level Interface Kit) for all interested
parties, which includes all of the information necessary for driver
development. Prerequisite is an application development kit from AVM.
The application development kit is available from AVMs FTP site (ftp.avm.de) 
and from the AVM Data Call Center (++49-30-399 84 300), using the 'Connect' 
tool, in the developer section.
