Chapter 12 NetCAPI

This section describes how to configure your ZyXEL Device to be a NetCAPI server.

By default, NetCAPI is enabled on your ZyXEL Device. When NetCAPI is enabled, the 
ZyXEL Device listens for incoming DCP messages from the computers. By default, the 
ZyXEL Device listens for DCP messages on TCP port 2578. 

The following figure illustrates the configuration used in this example. 

Figure 62   Configuration Example

Before entering any configurations, you must install the CAPI driver (RVS-CE) and 
communication program such as RVS-COM Lite on your computer.

RVS-COM includes an ISDN CAPI driver with its communication program.  RVS-CE (Core 
Engine) is an ISDN-CAPI 2.0 driver for Windows 95/98/NT that can be used by different 
ISDN communication programs (such as AVM Fritz or RVS-COM) to access the ISDN on the 
ZyXEL Device. 

NetCAPI can carry out CAPI applications only if the CAPI driver is installed on your 
computer. In addition to the CAPI driver, you will need a communication software program 
such as RVS-COM Lite, Fritz etc., for users to access CAPI. 

The ISDN router is a shared device and can be used by several different client workstations at 
the same time: e.g. one computer sending a fax, another computer doing a file transfer. RVS-
COM has to be installed on each client workstation in order to share the ISDN lines.

End IP

Enter the last IP address in a NetCAPI client group.

incoming calls and outgoing calls permissions. Select None if you wish to deny all 

calls.
