Abstract
An application program interface for integrated services digital networks is implemented so that application programs can be generated independently of network protocols (Layer 1, 2; 1TR6, VN2) and independently of the respective implementation of service features. The application program interface contains for each network service an independent service program module (Telephony, FAX, Packet data, Teletex, . . . ) with a message set representing procedures as specified by standards (CCITT, ETSI, . . . ).
