What it does

You can use ShareISDN to share the functions of an ISDN-Card with other users in a network. For example, every person within a company can send faxes, transfer files or access the Internet via one single ISDN-Card. Installing an ISDN-Card in every single computer of a network would give the same result but of course this would be much more expensive and requires a lot more effort (installing the cards, laying cables, etc).

Simply install the ShareISDN Server (SISsetNT.exe for WindowsNT/2000/XP/2003Server, SISset95.exe for Windows95/98/ME, ShareISDNServer.tar.gz for Linux) on the computer with the ISDN-Card. The ShareISDN Client (SICsetup.exe) is put on every computer to access the ISDN-Card of the Server computer.

You can use nearly every application which supports the CAPI 2.0 specification. CAPI 2.0 is the standard programming interface for ISDN-Cards and nearly all ISDN applications support it. For example, the widespreaded Fritz! software is compatible with ShareISDN.

The function of the ShareISDN package is also called "Remote Capi", "Lan Capi" or "Network Capi" to show the special characteristic: the whole Capi-Interface of the ISDN-Card is accessible from the client computers.

ShareISDN is compatible with the Remote Access Service (RAS) so you can make Dial-Up connections to the Internet via ShareISDN.

What it doesn't do

ShareISDN is not the right tool for multiple users accessing ONE SINGLE Internet Dialup connection.

It is possible to build an Internet connection via ShareISDN, but you cannot SHARE it with others. Other users can also use ShareISDN to build up an Internet connection via the same ISDN-Card, but they have to build up an independant Internet Dialup connection.
