DE2929452A1 - Authorised use of facilities in computer controlled PBX - are listed in store and changed by dialling special code which calls up change authorisation routine - Google Patents

Abstract

In a computer (ZST,ZSP) controlled PBX, use of various facilities, e.g. outside lines, is controlled by a block of stores (SB). This is organised in rows (Z1 to Zx), with columns for subscriber nos. (Tnl to Tnx), general data (Allg) and authorisation (BT). Up to 5 different authorisations (a to e) can be stored for each subscriber~ . To change an authorisation, a special code is dialled, which calls up the 'change authorisation' routine, followed by the subscriber no., which selects the appropriate row of the store. The authorisation digit to be changed is then dialled, and the 5 columns are searched to find it. If not present, the search stops on the first free column, i.e. containing 'O'. Then the new authorisation is dialled, which replaces the old one. The routine is released when the handset is replaced.

Description

Procedure for changing participant permissions in

a centrally controlled telephone exchange.

The invention relates to a method for changing 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 every connection state, from which if there is a corresponding incentive different rental 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. Farther is already suggested (VPA 77 P 6085) State memory to be provided, from which, depending on the current connection status, certain commands for functional sections can be derived 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 in a simple manner in To enable the form of a subscriber service that is entitled to do so by certain People for any subscriber station of the private branch exchange one any authorization registered, deleted or by another authorization can be replaced.

This is achieved in that each subscriber station in a specific Memory block in the changeable data memory one next to memory locations for general Station-specific data also memory locations for memory lines containing authorizations it is permanently assigned that a specific indicator is assigned to each authorization type is and that after controlling the memory locations for the authorizations of a subscriber station after choosing an authorization change identifier and the subscriber number the choice of an identifier for an authorization type of the storage space with this Authorization or - if this authorization has not yet been assigned to the subscriber station is - a free memory space for authorizations is controlled and that after subsequent selection of an identifier for another authorization this other Authorization is written into the selected memory location.

This has the advantage that in a simple manner Subscriber station an authorization in a different their authorization has to be changed or a new authorization has to be assigned to a subscriber station. In the method according to the invention there is also the advantage that by the possibility of allocating a storage space through any authorization assignment only relatively few corresponding storage spaces have to be provided.

The method according to the invention is explained with the aid of a figure. The figure consists essentially of a memory block SB of a data memory, an indicated central control device 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 in memory locations t'Allg "for general data and memory locations a to e (authorization part BT) divided for authorizations.

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 with existing switching centers for the switching staff and generally for maintenance personnel is necessary, in a simple and time-consuming manner Change authorizations of individual subscriber stations permanently or at short notice or to grant new authorizations or existing ones to individual subscriber stations to withdraw. For this purpose it is necessary that the authorization data of the individual subscriber stations assigned to their addresses (X subscriber numbers) in a fixed, predetermined area of a data memory, i.e. in a designated area Memory block are stored. This memory block makes sense in principle and must be with you all the time normal establishment of connections can be controlled and queried by the central control device.

In this memory block SB is expedient for the inventive Method each assigned to a storage location line of a subscriber station. For example contains the line z1 in the figure in addition to the station address and general station-specific Data in the storage locations all authorizations of the subscriber station Tn1, e.g. semi-official, authorized to office, authorized to remote office, etc.

As an example, it should be assumed that the subscriber station Tn1 instead the authorization stored in memory location a in line z1 has semi-official authorization the "officially authorized" authorization is to be assigned.

To do this, the person authorized to change an authorization chooses an authorization change identifier from any subscriber station. This indicator triggers the "Change Authorization" operation and thereby is first the aforementioned memory block from the central control device ZST SB with the individual data of the individual participants and in particular the data contained therein included authorization part BT controlled. This state is stored in a state memory saved.

If the person changing now selects the subscriber number of a subscriber station (e.g. Tn1) of the private branch exchange, then it is assigned to the from the status memory ZSP queried status feature belonging to the subscriber station Tn1 Storage space controlled for authorizations. In the present case this is the Memory line z1 in the area BT.

As already mentioned, each type of authorization should have its own identifier be assigned. Assuming that subscriber Tn1 has the authorization "" semi-official " allocated is that this authorization is stored in the memory location a in the authorization part BT and that this type of authorization is assigned the indicator "1" with semi-official authorization then the changing subscriber must first select the identifier "1" and control it automatically to the memory location "a". Reaching this space is indicated by a special clock mark, which, for example, comes from the Queries of the current status feature can take place.

The changing subscriber now knows that he is either authorized with the registration number 111 ?? or (if the selected subscriber station does not have a partial exchange authorization " had) controlled a free memory space in the BT area. One continues to go assumes that the authorization "officially authorized" is assigned the identifier "2" if the changing subscriber now chooses this indicator, then it will be in the memory location "a" overwrites the identifier "1" and replaced it with the identifier "2". In order to the subscriber station Tn1 has the authorization "authorized to office" and the clock signal is switched off.

If authorization "2" is to be assigned to a subscriber station Tn2, without deleting any other authorization, the person making the change then chooses Participants after dialing the participant number the authorization "0" and thus gets to a free memory location (e.g. d) in area BT of memory line z2. In this case, the special time sign sounds again, which means that at the same time it is displayed that there was still a free memory space. Now the number plate 2 " can be selected, whereby the corresponding authorization in memory location "d" of the Line z2 is stored.

Should a subscriber station (Tn3) be given an authorization (It2n) without replacement are taken, then the changing participant chooses after the election the subscriber number of, for example Tn3, the identifier (2) for the one to be deleted Authorization and then the identifier ("O") for a free storage space. Was the authorization (2) to be deleted, for example, at storage location llell in the Row z3 stored, then this place is now a free one for another Allocation of available storage space.

A change in authorization for other subscriber stations will be made in each case initiated by dialing the participant number. The repeated selection of the authorization change indicator is not necessary. The corresponding stored status characteristic - which one is queried again for each subscriber number dialing - only when you hang up of the handset at the subscriber station of the changing subscriber is deleted.

From the above it can be seen that it is with the help of the invention Procedure is possible in a simple manner in centrally controlled telephone exchange system ° 9iner any subscriber station by selecting a code quickly one after the other and without additional means to change the authorizations of individual subscriber stations, too delete or add to.
