in Windows 95/98/NT. Like all standard ISDN applications, the
driver addresses the ISDN-Controller through its CAPI 2.0
software interface. The NDIS WAN CAPI Driver for Windows 98
is implemented in accordance with the Win32 Driver Model
(WDM), and uses the CAPI driver’s kernel mode interface.
For a detailed description of the AVM NDIS WAN CAPI Driver’s capa-
bilities and complete installation instructions, please see the Help
file accompanying the NDIS WAN CAPI Driver for your operating sys-
tem on the FRITZ!Card CD.
4.4 ISDN CAPI Port or NDIS WAN CAPI Driver?
The possible applications of each driver concept are documented in
the accompanying Help files.
The two drivers also can be installed and operated simultaneously.
In weighing the advantages of the two driver concepts for using
ISDN in Windows, consider the following recommendations:

can be used to connect to Internet providers who offer PPP
over ISDN (synchronous PPP) connections in accordance with
RFC 1618. Ask your provider whether the PPP over ISDN
protocol is supported.
• Internet providers who offer ISDN dial-ins but do not sup-
port PPP over ISDN can generally be accessed using asyn-
chronous (“modem-style”) PPP with the corresponding CAPI
Port modem. Because the protocol settings can be changed
by AT commands, the
