Rvs-Com - ZyXEL Communications P-202 User Manual

series of standard commands to the terminal. The CAPI standard defines the commands and allows you to
use a well-defined mechanism for communications using ISDN lines.
CAPI also simplifies the development of ISDN applications through many default values that do not
need to be programmed. It provides a unified interface for applications to access the different ISDN services
such as data, voice, fax, telephony, etc.
ISDN-DCP
ISDN-DCP allows a workstation on the LAN to use services such as transmitting and receiving faxes as well
as placing and receiving phone calls.
Using ISDN-DCP, the Prestige acts as a DCP server. By default, the Prestige listens for DCP
messages on TCP port number 2578 (the Internet-assigned number for RVS-COM DCP). When the Prestige
receives a DCP message from a DCP client i.e., a workstation, the Prestige processes the message and acts on
it. Your Prestige supports all the DCP messages specified in the ISDN-DCP specification.

2.10.4 RVS-COM

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 Prestige.
NetCAPI can carry out CAPI applications only if the CAPI driver is installed on your workstation.
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 workstation sending a fax, another workstation doing a file transfer. RVS-COM has to be
installed on each client workstation in order to share the ISDN lines.
Configuring the P201 as a NetCAPI Server
This section describes how to configure your Prestige to be a NetCAPI server using the SMT (System
Management Terminal).
[Note : For configuring your Prestige with the PNC, use PNC version 2.10 and above.]
By default, NetCAPI is enabled on your Prestige. When NetCAPI is enabled, the Prestige listens for
incoming DCP messages from the workstations. By default, the Prestige listens for DCP messages on TCP
port 2578.
