COMMON-ISDN-API (CAPI)
is an application programming interface standard used to access
ISDN equipment connected to basic rate interfaces (BRI) and
primary rate interfaces (PRI). By adhering to the standard,
applications can make use of well defined mechanism for communications
over ISDN lines, without being forced to adjust to the idiosyncrasies
of hardware vendor implementations. ISDN equipment vendors
in turn will benefit from a wealth of applications, ready
to run with their equipment.

COMMON-ISDN-API is well
established standard. Potential cost savings were the driving
force for COMMON-ISDN-API controller and application development.
Commercial users are rapidly migrating to ISDN (Integrated
Services Digital Network) as the principal vehicle for data
exchange of a wide range of formats.
