2.12 NetCAPI Setup

2.12.1 Basics

NetCAPI is ZyXEL's implementation of CAPI (Common ISDN Application Program Interface) capabilities
over a network. It runs over DCP (Device Control Protocol) developed by RVS-COM.
NetCAPI can be used for applications such as Eurofile transfer, file transfer, G3/G4 Fax, Autoanswer host
mode, telephony, etc. on Windows 95/98/NT p latforms.

2.12.2 CAPI

CAPI is an interface standard that allows applications to access ISDN services. Several applications can
share one or more ISDN lines. When an application wants to communicate with an ISDN terminal it sends a
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.

2.12.3 ISDN-DCP

ISDN-DCP allows a workstation on the LAN to use services such as transmitting and receiving fa xes as well
as placing and receiving phone calls.
