The CAPI API
Being a common interface, the ISDN CAPI (Common Application Program Interface), allows software
programs to use all ISDN services. Computer programs have access t o most services and features of ISDN
when used with CAPI. This access is hardware-independent. CAPI makes call numbers availabl e, as well
as several kinds of service information: caller number, called number, c a ll c h arges, ISDN service ID. CAPI
also facilitates transmission of data, FAX, or voice, and multiple B -channels can also be used
simultaneously on a single call.
It is the capabilities of the ISDN adapter and the type of ISDN connection that determine which services
and features are actually available. CAPI merely serve s as a common interface. ISDN CAPI is a platform-
independent standard which can be used in non-Windows operating systems like OS/2 and UNIX, as well
as in Microsoft operating systems.
CAPI 2.0 is the current form of CAPI. ISDN adapters with CAPI 2.0 can be used anywhere in Europe with
the DSS1 Euro-ISDN connection.
Intro to API Single-Channel and MultiLink Examples
In the following procedures, you will use Application Program Interfaces (APIs) to set up and use dial-up
networking with the MT128ZLX in conjunction with the par ticular operating system your computer is
using. The APIs are installed as part of the MT128ZLX driver i nstallation, which must be complete before
these procedures can be done. Note that the procedures presented here are examples only. Your use of
APIs will depend on the needs and limitations of your operating environment.
