Flexible call-processing apparatus for ISDN telephone channels
First Claim
1. An ISDN call-processing system comprising:
- A) an input device for generating behavior signals that represent inpulse rules that specify behavior to be followed in response to receipt of ISDN data-channel messages, wherein some of these rules specify information elements; and
B) a switching system, including;
i) an input port coupled to the input device for reception of the behavior signals therefrom;
ii) at least one network port adapted for connection to a respective network line for reception therefrom of ISDN data-channel messages that reference respective calls; and
iii) a host port adapted for coupling to a host computer for reception therefrom of host input signals that associate inpulse rules with respective calls and for transmitting to the host information requested by the information elements specified in the inpulse rules, the switching system storing the inpulse rules represented by the behavior signals and responding to reception of ISDN data-channel messages from the network line in accordance with the thus-stored inpulse rules.

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).

14. An ISDN call-processing system comprising:
-
A) an input device for generating behavior signals that represent outpulse rules that specify ISDN data-channel messages to be sent, certain of the behavior signals specifying information to be sent to a host computer; B) a switching system, including; i) an input port coupled to the input device for reception of the behavior signals therefrom; ii) at least one network port adapted for connection to a respective network line for reception therefrom of ISDN data-channel messages that reference respective calls; and iii) a host port adapted for coupling to the host computer for reception therefrom of host input signals that specify outpulse rules to be executed for respective calls, the switching system storing the outpulse rules represented by the behavior signals and responding to reception at the host port of host input signals that are applicable to the outpulse rules by sending ISDN data-channel messages to the host in accordance with the applicable thus-stored outpulse rules. - View Dependent Claims (15, 16)

17. A call processing system for processing calls over a digital system, the call processing system including:
-
A) an input device for generating behavior signals that represent rules that specify data-channel messages to be sent, the rules specifying the types of information to be included in the specified messages; B) a switching system, including; i) an input port coupled to the input device for reception of the behavior signals therefrom; ii) at least one network port adapted for connection to a respective network line for reception therefrom of data-channel messages that reference respective calls; and iii) a host port adapted for coupling to a host computer for reception therefrom of host input signals that specify rules to be executed for respective calls, for storing the rules represented by the behavior signals and responding to reception of messages over the data-channel by performing operations in accordance with the applicable rules and sending data-channel messages to the host in accordance with the rules, the switching system including in the messages information of the types specified therein. - View Dependent Claims (18, 19)
