ABSTRACT:
A call processor (10) for processing integrated-services digital-network (ISDN) calls is subject to real-time control by a host computer (28) but stores rules specified ahead of time by a manual input device (32). By changing the entered rules, a user can adapt the call processor to a wide variety of applications without burdening the host (28) with operational details in real time. In particular, the behavior specifications represent choices among the ISDN data-channel messages and contents that the call processor (10) will forward to the host computer (28) in reporting receipt of those messages. The behavior specifications also represent choices for transmitted ISDN data-channel messages and contents generated by the call processor (10) either autonomously or in conjunction with the host computer (28).
