AVM ISDN CAPI Port Driver
AVM ISDN CAPI Port Driver
The AVM ISDN CAPI Port Driver allows you to use an ISDN-
Controller 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 all of the various communications
options of Windows can be used with all AVM IS-
DN-Controllers. For example, you can use Dial-Up Networking
and the TCP/IP protocol to dial into your Internet Service Provider.
A number of different “virtual modems” preset for a variety
of purposes can be selected in Windows applications such
as Dial-Up Networking, Microsoft Exchange/Outlook and Microsoft
Money. Just select a pre-configured destination to
launch ISDN communication.
AVM ISDN NDIS WAN CAPI Driver
The AVM ISDN NDIS WAN CAPI Driver for Windows allows use
of RAS (Remote Access Service) and dialing into Internet Service
Providers over ISDN.
NDIS (Network Device Interface Specification) is a standard
for connecting network adapters (hardware) to network protocols
(software). NDIS WAN is a Microsoft extension of this
standard for wide-area networking (WAN). The AVM ISDN
NDIS WAN CAPI Driver thus allows the ISDN-Controller to be
used as a network adapter addressed over the CAPI 2.0 applications
interface.
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”).
