DE2929514A1 - METHOD FOR INQUIRING PARTICIPANT RIGHTS IN A CENTRALLY CONTROLLED TELEPHONE EXTENSION SYSTEM - Google Patents

Abstract

A functional process - authorisation check - is initiated from each subscriber station (Tn1 to Tnx) of a telephone PABX system by dialling a code, and a specific authorisation type is selected by further dialling. On the basis of further consecutive dialling of any given subscriber numbers, a memory block (SB) is checked for the presence or absence of the selected authorisation type and corresponding acoustic signals are emitted. <IMAGE>

Description

Procedure for querying participant authorizations in

a centrally controlled telephone exchange.

The invention relates to a method for querying subscriber authorizations in a centrally controlled private branch exchange with a speech path coupling network and with for the exchange of switching technology, for the connection establishment data, addresses and control commands transmitted over the speech path coupling network between sub-control units intended for different tasks and modifiable ones Data storage with data transmission line bundles that enable the exchange of information, with working and program memories and with state memories for storing the in switching measures possible for each connection state, from which if there is a corresponding incentive different mediation processes can be triggered.

A centrally controlled one relating to the method according to the invention Telephone private branch exchange is already known from DE-AS 26 47 404.

A connection status memory has also already been proposed (VPA 77 P 6085) to provide, from which, depending on the current connection status, certain commands for functional sections in the program memory.

Furthermore, it is already proposed (VPA 78 P 6105), certain subscriber services in connection with an election evaluation.

The invention is based on the object of providing a subscriber service enable, which consists in a centrally controlled private branch exchange in a simple manner from any subscriber station by authorizing this Individuals have a specific authorization for any number of subscriber stations the system can be queried in quick succession.

This is achieved in that in a specific memory block A memory line is permanently assigned to each subscriber station in the changeable data memory and that in the same place in each of these memory lines of each type of authorization a certain storage space is allocated. so that there is a column for a particular Authorization results, wherebyM continues to be due to a special condition store saved connection status with a first selected identifier the memory block and with a subsequent second identifier a specific one Column can be controlled for a certain type of authorization and with the following Choice of any number of subscriber numbers by dialing tone or busy tone or lack of the appropriate authorization for the selected subscriber number corresponding subscriber station is displayed.

This has the advantage that, for example, through the maintenance and test personnel or operator personnel from any subscriber station from a certain type of authorization for the individual subscriber stations of the private branch exchange are queried can.

The method according to the invention is explained with the aid of a figure. The figure consists essentially of a memory block SB. a data memory, an indicated central control ZST and an indicated state memory ZSP. The memory locations in the memory block SB are each assigned to a subscriber station Lines Z1 to Zx and columns assigned to each type of authorization, Spl to Spy arranged.

Details of a centrally controlled private branch exchange, How it is based on the method according to the invention, are from DE-AS 26 47 404 to be found.

It is particularly in such a private branch exchange in the case of existing switching centers for the switching staff and in general practical for the maintenance staff, in a simple and time-consuming way Way to determine or to check which subscriber stations a particular Authorization is assigned.

For this purpose it is necessary that the authorization data of the individual subscriber stations in assignment to their addresses in a fixed predetermined Area of a data memory, i.e. stored in a memory block provided for this purpose are. This memory block is usually in principle and must also continuously controllable by the central controller during the normal establishment of connections and be queryable.

In this memory block is expedient for the inventive Move one memory line at a time Subscriber station assigned. For example, line Z1 in the figure contains all but the station address Authorizations of the subscriber station Tn1. As permissions in the present Figure entered: HA = semi-authorized, A = authorized to official, FA = authorized to remote office, K = authorized to conference, U = authorized to transfer the call, OPEN = authorized to intrude. The individual authorizations are assigned to the storage locations in a row, that the resulting columns Sp1 to SW of the memory block SB each have one assigned to a specific authorization.

If the maintenance personnel now want to check, for example, whether the subscriber stations Tn1, Tn3 and Tnx are authorized to act, then this can be done from any subscriber station a key figure assigned for this purpose can be selected. This key figure triggers the work process "Check authorization" and results in a state memory for the connection flow a corresponding condition feature. This condition feature resolves after scanning the central control device ZST "connection to the memory block SB" from what the examining participant by a special tone or simply by ahlton is shown. Now the examining participant chooses a second key figure, the Corresponds to the type of authorization that is to be checked. Then the examiner can Subscriber successively the subscriber numbers of the subscriber stations Tn1, Tn3 and Select Tnx. At the end of a subscriber number, he receives an exchange authorization Dial tone and busy tone if there is no trunk authorization. During this time If the status feature "Memory block SB is occupied" is in the status memory ZSP Check, Office authorization "inscribed, which the central control device upon entry queries each new subscriber number. To query another type of authorization - at- for example the conference authorization - is then only to select another code corresponding to this authorization. It is fundamentally provided that these key figures are known only to a limited group of people.

From the above it can be seen that it is with the help of the invention Method is possible in a simple manner in centrally controlled telephone exchange systems from any subscriber station by dialing the code in quick succession and query the authorizations of individual subscriber stations without additional means.
