4. Drivers and Applications

The NDIS WAN Miniport driver is therefore optimally suited for the following

applications:

Internet access - The Dial-Up Network establishes an ISDN connection

with your Internet provider. The Web browser (Netscape, Internet

Explorer) or the E-mail client subsequently use this connection like a

TCP/IP LAN connection to the Internet.

Direct connection of two PCs - The Dial-Up Network establishes a

connection to a second PC via ISDN. Windows Explorer then creates a

Windows network connection between the PCs using the NetBEUI

protocol. Once this is done, each PC can access the other PC’s hard disk

just like a disk on a LAN server; data can be copied or moved, and

applications can be run.

Connection between a remote PC and a LAN - The Dial-Up Network

establishes a connection to a router or server connected to a LAN, e.g. a

company server. Subsequently, Windows Explorer establishes a Windows

network connection using the NetBEUI, TCP/IP, or IPX protocol. Once this

is done, each PC can access the other PC’s hard disk via ISDN as if it

were connected directly to the LAN. In this manner, it is possible to

duplicate your in-company working environment at your home office.

Thanks to the high speed of the ISDN connection, remote access is

convenient and fast.

The Siemens ISDN Adapter in conjunction with the NDIS WAN Miniport driver is

integrated into Windows as a network interface card during installation. To this end,

the system environment consisting of the ISDN Accelerator Pack, Dial-Up Network,

and LAN protocol (NetBEUI, TCP/IP, IPX) is examined and completed as needed.

Subsequently, the requisite internal connections to these components are

established.

The NDIS WAN Miniport hardware driver is also used by the other ISDN interfaces

(CAPI, VCOMM). It is entered as a network adapter in the Windows registry.

4.3 CAPI

The CAPI (Common Application Program Interface) was defined to be able to

develop ISDN applications independently of the proprietary characteristics of ISDN

adapters. One of the most remarkable CAPI features is platform independence. In

addition to Windows, the CAPI has been defined for Unix, OS/2, and other

operating systems. The older CAPI Version 1.1 should no longer be used; the

current CAPI version is 2.0.
