AVM ISDN CAPI Port Driver
46 ISDN-Controller C2 – 8 AVM System Architecture
AVM ISDN CAPI Port Driver
The AVM ISDN CAPI Port Driver allows you to use the AVM
ISDN-Controller C2 as if it were a modem.
The AVM ISDN CAPI Port Driver makes it possible for even
programs designed for analog modems to communicate over
the ISDN interface. This means that the various communica-
tion functions of Windows can be used with the AVM ISDN-
Controller C2.
The AVM ISDN CAPI Port Driver generates a number of virtual
modems in your system. The various modems are pre-config-
ured for different types of connections. Virtual modems al-
low you to dial up ISDN connections to the Internet or to BBS
services, for example, or to set up RAS (Remote Access Ser-
vice) connections to other computers over ISDN.
AVM NDIS WAN CAPI Driver
The AVM NDIS WAN CAPI Driver for Windows allows use of
RAS (Remote Access Service) and dialing into Internet Ser-
vice Providers over ISDN.
NDIS (Network Device Interface Specification) is a standard
for connecting network adapters (hardware) to network pro-
tocols (software). NDIS WAN is a Microsoft extension of this
standard for wide-area networking (WAN). The AVM NDIS
WAN CAPI Driver thus allows the ISDN-Controller C2 to be
used as a network adapter, mediating between network pro-
tocols and the AVM ISDN-Controller C2's applications inter-
face CAPI 2.0.
Unlike the AVM ISDN CAPI Port Driver, the AVM NDIS WAN CA-
PI driver cannot be controlled by AT commands. It uses the
standard protocols for network connections over ISDN
(“HDLC” and “PPP over ISDN”).
AVM ISDN TAPI Services for CAPI
AVM ISDN TAPI Services for CAPI are universal drivers which
can be used to implement TAPI applications with AVM ISDN-
Controllers in Windows.
