Abstract
Abstract The adjunct call processing arrangement of our invention eliminates the separation between hard-wired telephone switching system computer facilities and customer owned switchably connectable computer facilities. A general purpose communication interface is provided which connects the customer provided computer facilities to both the switching network and the hard-wired system processor of the telephone switching system via the standard telephone switching system port circuit. This general purpose communication interface enables a customer provided computer facility to provide additional call processing capability. In particular, the attendant services call processing subroutines and the directory assistance data base and software are provided on the computer facility. The telephone switching system routes all attendant-directed calls to a telephone station set associated with the computer and transmits call related data to the computer. The computer performs the necessary call processing and transmits a message back to the telephone switching system to indicate the switching system operation necessary to provide the requested service.

Claim 5
Dependent Claim
26 words
The method of claim 3 wherein the step of executing includes: generating control data to activate said switching network to implement said call processing service request.
Claim 6
Dependent Claim
37 words
The method of claim 4 wherein the step of processing includes: transmitting a control message containing said control data from said computer facility to said system processor via said control signalling channel to activate said switching network.
Claim 7
Dependent Claim
29 words
The method of claim 5 including the step of: establishing a communication connection through said switching network from said requesting equipment to a destination identified by said control message.
Claim 8
Dependent Claim
196 words
In a switching system which serves a plurality of terminal equipment, each of which is connected by an associated port circuit to a switching network of said switching system, which switching network establishes network connections among said terminal equipment by interconnecting said associated port circuits, an adjunct call processing arrangement comprising: system processor means connected to said switching network for controlling the interconnection of said port circuits by said switching network; control signalling means connected to and interconnecting said system processor means and said port circuits for exchanging control signals therebetween; computer facility means for executing a predefined set of call processing routines; interface means connected to and interconnecting said computer facility means and said control signalling means; wherein said system processor means is responsive to a predefined service request from any of said terminal equipment for transmitting a call record identifying said service request and said requesting terminal equipment to said computer facility means via said control signalling means and said interface means; and wherein said computer facility means is responsive to said call record for executing one or more of said call processing routines to provide said requested service to said requesting terminal equipment.
Claim 9
Dependent Claim
196 words
In a switching system which serves a plurality of terminal equipment, each of which is connected by an associated port circuit to a switching network of said switching system, which switching network establishes network connections among said terminal equipment by interconnecting said associated port circuits, an adjunct call processing arrangement comprising: system processor means connected to said switching network for controlling the interconnection of said port circuits by said switching network; control signalling means connected to and interconnecting said system processor means and said port circuits for exchanging control signals therebetween; computer facility means for executing a predefined set of call processing routines; interface means connected to and interconnecting said computer facility means and said control signalling means; wherein said system processor means is responsive to a predefined service request from any of said terminal equipment for transmitting a call record identifying said service request and said requesting terminal equipment to said computer facility means via said control signalling means and said interface means; and wherein said computer facility means is responsive to said call record for executing one or more of said call processing routines to provide said requested service to said requesting terminal equipment.
