Common ISDN Application Programming Interface
Common-ISDN-API
<networking> (CAPI, Common-ISDN-API) A programming interface
standard for an application program to communicate with an
{ISDN} card.
Work on CAPI began in 1989, focussing on the German ISDN
protocol, and was finished in 1990 by a CAPI working group
consisting of application providers, ISDN equipment
manufacturers, large customers, user groups and DBP Telekom,
resulting in COMMON-ISDN-API Version 1.1. Following
completion of the international protocol specification, almost
every telecommunication provider offers {BRI} and {PRI} with
{protocols} based on {Q.931} / ETS 3009 102. Common-ISDN-API
Version 2.0 was developed to support all Q.931 protocols.
Latest version: 2.0, as of 1998-09-07.
