Figure explained The figure consists essentially of a memory block SB of a data memory, an indicated central controller ZSTT and an indicated status memory ZSP. The memory locations in the memory block. SB are arranged in rows ZA to Zx each assigned to a subscriber station and in columns Sp 1 to Spy assigned to each type of authorization

Details of a centrally controlled private branch exchange, How it is accessible to the method according to the invention are from DE-AS 26 47 404 refer to. In such a private branch exchange, it is particularly the case with existing exchanges for the switching staff and in general for the maintenance staff expedient, in simple and It takes little time to determine or to check which subscriber stations a particular one Authorization is assigned For this purpose it is necessary that the authorization data of the individual Subscriber stations assigned to their addresses in a fixed, predetermined area of a data memory, d. H. are stored in a memory block provided for this purpose. This memory block is usually basically an advantage and must also be used continuously during the normal establishment of connections the central control can be controlled and queried.

In this memory block is expediently for the inventive method a respective storage line of a subscriber station assigned, for example contains the line Z1 in the figure other than the station address all the permissions of Teilnehmei ^ tation Tn 1. When permissions are registered in the present Figure: HA = semi-restricted A =-restricted , FA = remote exchange authorization, K = conference authorization, U - authorization to transfer the call, OPEN = authorization to intrude. The individual authorizations are assigned to the memory locations in a row in such a way that the resulting columns Sp 1 to Spy of the memory block SB are each assigned to a specific authorization.

If the maintenance staff now wants to check, for example, whether the subscriber stations Tn 1, Tn 3 and Tnx are authorized to act, then an assigned code number can be selected for this from any subscriber station. This code number triggers the “authorization check” process and results in a status memory (ZSP) for the connection flow. This status feature triggers after scanning by the central control device ZST "lock onto the memory block SB" , which is indicated to the checking subscriber by a special tone or simply by dialing tone, the checking subscriber dials a second code number that corresponds to the type of authorization that is being checked shall be. Then the checking subscriber can successively dial the subscriber numbers of the subscriber stations Tn 1, Γη 3 and Tnx . At the end of a subscriber number, he receives dialing signals if he has access authorization and busy signals if there is no authorization. During this time, the status feature “memory block SB occupied check, trunk authorization” is written in the status memory ZSP, which the central control device queries when each new subscriber number is entered. In order to query a different type of authorization - for example conference authorization - all that needs to be selected is a different code corresponding to this authorization. Dabsi, it is generally assumed that these key figures are only known to a limited group of people. '

From the above it can be seen that with the aid of the method according to the invention it can be done in simple? Way is possible in centrally controlled telephone exchange systems from any participant station by selecting a code quickly one after the other and query the authorizations of individual subscriber stations without additional means.

Claims (1)

Claim: Method for querying subscriber authorizations in a centrally controlled telephone branch exchange with several subscriber stations, with a speech path coupling network and with the exchange of switching-related data transmitted via the speech path coupling network, addresses and control commands between sub-control units provided for different tasks and changeable data storage units enabling data transmission line bundles with State memories for storing the switching measures possible in each connection state, whereby different switching processes can be triggered with a corresponding stimulus, a memory line being permanently assigned to each subscriber station in a specific memory block of a changeable data memory and a specific memory location being assigned at the same location in each memory line to each type of authorization, so that there is a column for a certain authorization, where we iterhin on the basis of a special connection status stored in the status memory by means of selection of the corresponding identifier in the mentioned memory block for a subscriber station, a certain type of authorization can be controlled, characterized in that from each subscriber station (Tn 1 to Tnx) by first selecting a K ^ nnzah! an acoustic signal to determine the existence or non-existence of the previously selected type of authorization can be queried for initiating a work process "checking authorization" and then selecting a trimmed authorization type in the memory block one after the other by successively dialing any number of subscriber numbers of the telephone extension system. The invention relates to a method for querying subscriber authorizations in a centrally controlled private branch exchange system with several subscriber stations, with a speech path coupling network and with the exchange of switching data transmitted over the speech path coupling network for establishing connections, addresses and control commands between subcontrols provided for different tasks and data transmission line bundles that allow for different tasks , with state memories for storing the switching measures possible in each connection state, whereby different switching processes can be triggered with a corresponding stimulus, a memory line being permanently assigned to each subscriber station in a specific memory block of a changeable data memory and a specific memory location being assigned to each type of authorization at the same place in each memory line . so that there is a column for a specific authorization, with a particular one in the state spcirlnT (! cspcifhorloii VerhiiKlungs / iislniuli's by means of selection of appropriate codes in the mentioned memory block for a subscriber station te authorization type can be controlled. , A centrally controlled telephone exchange system relating to the method according to the invention is already known from DE-AS 26 47 404.
It is also known from DE-OS 27 24 077 to provide connection status memories, from which, depending on the current connection status, certain commands for Ftaiktionsäbschnitte in the program memory are derived. ■; '-.-, .. ■: ■: To furthermore, it is known from DE-OS 28 25 278, certain Introduce subscriber services in connection with an election assessment. From DE-AS 23 04 925 a circuit arrangement for a computer-controlled telephone switching system is known with a changeable table of authorizations The change in the authorization table, This takes place in which a storage space does not necessarily have to be provided for each participant with the help of input units specially provided for the control computer. From DE-OS 240S 32S is a method and a Arrangement for storing and retrieving information in or from a storage device is known, telephone subscribers using their handset over a two-wire line to search for keywords into the storage device and transmitted through the two-wire line to the earpiece of the handset Speech signals Instructions for the further input of search terms, the required information or receive information that the requested information cannot be provided. The known procedure sees a multi-step dialogue between the telephone subscriber and the information system before, the telephone subscriber being informed by sound, in particular voice signals. After The solution is to inform the telephone subscriber seeking information through audio frequency signals can, in the exemplary embodiment, however, speech signals are only clearly interpretable for the subscriber turned off Accordingly, the known arrangement has a buffer memory for storing all Search terms and a language converter. The invention is based on the object to enable a subscriber service, which consists in that in a centrally controlled private branch exchange in a simple manner from any subscriber station a selectable specific authorization for any number of persons authorized to do so Subscriber stations of the system in quick succession so can be queried. This is achieved in that from each subscriber station by selecting a key figure for the first time to initiate a work process »check authorization« and then successively selecting a certain type of authorization in the memory block by consecutively dialing any number of subscriber numbers of the telephone connection system an acoustic signal to determine the presence or absence of the previously selected authorization can be queried. This results in the advantage that, for example, by the maintenance and testing staff or staff from any particular solution in a simple manner, in quick succession, a h "j correct type of authorization for the individual subscriber staiioncn der Fcrnsprcchncbcnslcllcnnnliigc iibgcfrngi can be.
