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.
