Abstract
Abstract A telephone switching center is controlled by a server computer (22) utilizing a Hypertext Transfer Protocol (HTTP), which is connected to a World Wide Web (WWW) network. It is proposed to provide, between a HTTP server (22) and the switching system (23), a control program (20) which enables control of a CTI application by the HTTP server (22). The proposed CTI application (20) provides an interface which uses a Universal Resource Locator (URL) specifying high level communicating functions which are independent of the respective interface (21) to the switching system or the CTI server.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
114 words
A system for providing an interface between a client device in a computer network and a telephone switching system (TSS) which controls telephone connections over a public switched telephone network (PSTN) using switching commands conforming to PSTN protocols, said telephone switching system having a system management interface, said interface-providing system comprising: a network server for receiving user commands from the client device through the computer network, said user commands conforming to standard client/server communication network protocols; and a protocol processor connecting said network server and the telephone switching system through the system management interface of said telephone switching system, said protocol processor converting user commands into corresponding switching system commands conforming to TSS protocols.
Claim 2
Independent Claim
114 words
A system for providing an interface between a client device in a computer network and a telephone switching system (TSS) which controls telephone connections over a public switched telephone network (PSTN) using switching commands conforming to PSTN protocols, said telephone switching system having a system management interface, said interface-providing system comprising: a network server for receiving user commands from the client device through the computer network, said user commands conforming to standard client/server communication network protocols; and a protocol processor connecting said network server and the telephone switching system through the system management interface of said telephone switching system, said protocol processor converting user commands into corresponding switching system commands conforming to TSS protocols.
Claim 3
Dependent Claim
22 words
A system according to claim 1 wherein the computer network is a local area network utilizing an HTTP protocol for user commands.
Claim 4
Dependent Claim
22 words
A system according to claim 2 wherein the computer network is a wide area network utilizing an HTTP protocol for user commands.
Claim 5
Independent Claim
130 words
A method for controlling a telephone switching system (TSS) from a client device in a computer network wherein the telephone switching system provides switching commands conforming to public switched telephone network (PSTN) protocols for controlling a PSTN, said telephone switching system having a system management interface, said method comprising the steps of: entering user commands into the computer network from the client device, said user commands conforming the computer network protocols; receiving the entered user commands at a network server; converting the entered user commands at the network server to provide switching system commands conforming to TSS protocols; and transmitting the system switching commands to the telephone switching system through the system management interface to enable the telephone switching system to perform operations in accordance with the system switching commands.
Claim 6
Independent Claim
130 words
A method for controlling a telephone switching system (TSS) from a client device in a computer network wherein the telephone switching system provides switching commands conforming to public switched telephone network (PSTN) protocols for controlling a PSTN, said telephone switching system having a system management interface, said method comprising the steps of: entering user commands into the computer network from the client device, said user commands conforming the computer network protocols; receiving the entered user commands at a network server; converting the entered user commands at the network server to provide switching system commands conforming to TSS protocols; and transmitting the system switching commands to the telephone switching system through the system management interface to enable the telephone switching system to perform operations in accordance with the system switching commands.
Claim 7
Dependent Claim
98 words
A control system for a telephone switching system having a system management interface over which telephony commands can be received to control the operation of the telephone switching system, said control system comprising: a data communications server for receiving requests for telephone switching system operations from a remote client system, said requests conforming to a standard data communications protocol; and a computer-telephony integration (CTI) processor for mapping each of said requests to a command having a format acceptable to the telephone switching system, said CTI processor providing each command to the telephone system over the system management interface.
Claim 8
Dependent Claim
98 words
A control system for a telephone switching system having a system management interface over which telephony commands can be received to control the operation of the telephone switching system, said control system comprising: a data communications server for receiving requests for telephone switching system operations from a remote client system, said requests conforming to a standard data communications protocol; and a computer-telephony integration (CTI) processor for mapping each of said requests to a command having a format acceptable to the telephone switching system, said CTI processor providing each command to the telephone system over the system management interface.
Claim 9
Dependent Claim
44 words
A control system as set forth in claim 5 wherein the requests received at the data communications server include at least requests for call setup, call termination, call forwarding and call conferencing operations to be performed under the control of the telephone switching system.
Claim 10
Dependent Claim

Claim 15
Independent Claim
84 words
A method for controlling a telephone switching system having a system management interface on which telephone switching system commands are received, said method comprising the steps of: receiving requests for telephone switching system operations, said requests conforming to a standard data communications protocol; mapping each of said requests to a command having a format acceptable to the telephone switching system; transferring each of said commands to the telephone system through the system management interface; and executing each transferred command in the telephone switching system.
Claim 16
Dependent Claim
