NetCAPI
Your ZyXEL router can take full advantage of popular European ISDN services. 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 platforms.
7.3.1 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.
7.3.2 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.
