Abstract
Abstract A telecommunications system includes a network of coupled telecommunication exchanges (PABX1, PABX2, PABX3). At least one of the exchanges is coupled to a processor (COMP) via a so-called Computer Telephony Interface (CTI). The exchanges monitor state information for extensions (TLPH1, TLPH2, TLPH3) that are connected to the exchanges. A router routes the state information to the exchange which is coupled to the processor. That exchange transfers the state information to the processor.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
146 words
A telecommunication system comprising a. data processing means from any exchanges (COMP), b. a first telecommunication exchange (PABX1) coupled to the data processing means (COMP), c. at least a second telecommunication exchange (PABX2) coupled to the first telecommunication exchange (PABX1), which second telecommunication exchange (PABX2) comprises I. monitoring means (MO2) for acquiring state information about the state of extensions (TLPH2) that can be connected to the second telecommunication exchange (PABX2), the state information being for use by the data processing means (COMP), and ii. routing means (IF2, RT2) for routing the state information to the data processing means via the first telecommunication exchange (PABX1), so that the entire system has CSTA functionality, and so that the division between the first and second exchanges is transparent from the point of view of the CSTA functionality, the term "CSTA" herein being an abbreviation for Computer Supported Telecommunications Application.
Claim 2
Dependent Claim
146 words
A telecommunication system comprising a. data processing means from any exchanges (COMP), b. a first telecommunication exchange (PABX1) coupled to the data processing means (COMP), c. at least a second telecommunication exchange (PABX2) coupled to the first telecommunication exchange (PABX1), which second telecommunication exchange (PABX2) comprises I. monitoring means (MO2) for acquiring state information about the state of extensions (TLPH2) that can be connected to the second telecommunication exchange (PABX2), the state information being for use by the data processing means (COMP), and ii. routing means (IF2, RT2) for routing the state information to the data processing means via the first telecommunication exchange (PABX1), so that the entire system has CSTA functionality, and so that the division between the first and second exchanges is transparent from the point of view of the CSTA functionality, the term "CSTA" herein being an abbreviation for Computer Supported Telecommunications Application.
Claim 3
Dependent Claim
56 words
A telecommunication system as claimed in claim 1, wherein the second telecommunication exchange (PABX2) comprises manipulation means (MA2) for manipulating the extensions (TLPH2) in response to manipulation instructions coming from the data processing means (COMP) and the first telecommunication exchange (PABX1) comprises routing means (IF1,RT1) for routing the manipulation instructions to the second telecommunication exchange (PABX2).
Claim 4
Dependent Claim
22 words
The system of claim 1, wherein the routing means uses addressing information for directing the state information toward the data processing means.
Claim 5
Dependent Claim
31 words
The system of claim 1 wherein the data processing means processes state information of the second exchange even though the data processing means is only directly connected to the first exchange.
Claim 6
Dependent Claim
22 words
The exchange of claim 4 wherein the routing means uses address information for directing the state information from the data processing means.
Claim 7
Dependent Claim
35 words
The exchange of claim 5, wherein the routing means allows the data processing means to communicate state information to the further exchange even though the data processing means is only directly connected to the exchange.
Claim 8
Dependent Claim
42 words
The exchange of claim 4, wherein the state information is of a format usable by the data processing means after conversion by the CSTA functionality and the routing means allows the state information to be routed via voice lines of the PABX.
Claim 9
Dependent Claim
42 words
The system of claim 1 wherein the state information is of a format usable by the data processing means after conversion by the CSTA functionality and the routing means allows the state information to be routed via voice lines of the PABX.
Claim 10
Dependent Claim
35 words
The system of claim 1 comprising at least one further data processing means, wherein the routing means allows the entire system to have a CSTA functionality with respect to which divisions between exchanges is transparent.
Claim 11
Dependent Claim
131 words
A telecommunication exchange (PABX2) comprising a. monitoring means (MO2) for obtaining state information about the state of extensions (TLPH2) connectable to the telecommunication exchange (PABX2), the state information being for use in data processing means (COMP), which data processing means is functionally separate from any exchange, and b. routing means (IF2,RT2) for routing the state information to a further telecommunication exchange (PABX1) that can be coupled to the telecommunication exchange (PABX2), the further exchange being arranged for transferring state information to the data processing means, so that any system containing the exchange has CSTA functionality, and so that the division between the exchange and any such further exchange is transparent from the point of view of the CSTA functionality, the term "CSTA" herein being an abbreviation for Computer Supported Telecommunications Applications.
Claim 12
Dependent Claim
131 words
A telecommunication exchange (PABX2) comprising a. monitoring means (MO2) for obtaining state information about the state of extensions (TLPH2) connectable to the telecommunication exchange (PABX2), the state information being for use in data processing means (COMP), which data processing means is functionally separate from any exchange, and b. routing means (IF2,RT2) for routing the state information to a further telecommunication exchange (PABX1) that can be coupled to the telecommunication exchange (PABX2), the further exchange being arranged for transferring state information to the data processing means, so that any system containing the exchange has CSTA functionality, and so that the division between the exchange and any such further exchange is transparent from the point of view of the CSTA functionality, the term "CSTA" herein being an abbreviation for Computer Supported Telecommunications Applications.
Claim 13
Dependent Claim
22 words
The exchange of claim 10, wherein the routing means uses addressing information for directing the state information toward the data processing means.
Claim 14
Dependent Claim
33 words
The exchange of claim 11, wherein the routing means enables the data processing means to process state information of the exchange even though the data processing means is functionally separate from the exchange.
Claim 15
Dependent Claim
42 words
The exchange of claim 10, wherein the state information is of a format usable by the data processing means after conversion by the CSTA functionality and the routing means allows the state information to be routed via voice lines of the PABX.
Claim 16
Dependent Claim
96 words
A telecommunication exchange (PABX1) arranged for receiving extension-manipulation instructions from data processing means (COMP), said data processing means being functionally separate from any exchange, characterized in that the telecommunication exchange (PABX1) comprises routing means (IF1,RT1) for routing the manipulation instructions to a further telecommunication exchange (PABX2), so that any system containing the exchange and the further exchange has CSTA functionality, and so that the division between the exchange and any such further exchange is transparent from the point of view of the CSTA functionality, the term "CSTA" herein being an abbreviation for Computer Supported Telecommunications Application.
Claim 17
Dependent Claim
