DK 155067 B

The invention relates to a dialing device with call number or identification storage as defined in the preamble of claim 1.

Such a selection device for automatic selection of a telephone subscriber terminal is known from German Publication Publication No. 24 22 545, where the numerical sequence of the number to be selected can be set in the storage by means of setting switches. It is a disadvantage that the adjusting couplers require a relatively large volume and that, if no precautionary measures are taken, they can be set reliably.

German publication specification 28 42 776 discloses a selection device for automatically building 15 data connections between stations over a dialing network, in which there is a call number storage, in which a call number number and an associated order can be stored. The loading is done by plugging wires using plugs. The same applies in the 20 above.

Furthermore, there are remote control and alarm systems which also work with selectors of the aforementioned kind, and whose call number bearings are made as core bearings, semiconductor bearings and other electronically programmable bearings.

It is a disadvantage of all known selectors that a newly programmed repository must be inserted or the repository must be programmed on site when new stations are established. The same precautions must be taken if, when using volatile buffer storage, disturbances occur in the power supply. In case of a general change of call number, the bearings must also be replaced or reprogrammed at all stations. These measures necessitate a large consumption of personnel and time.

The invention therefore aims to provide a selection device of the kind initially provided for, which allows for the establishment of stations or at 2 stations.

DK 155067 B

changing call numbers or commands, respectively, to settle for significantly less staff and time consumption.

The task is solved according to the invention with a selection device as claimed in claim 1.

5 It should be noted that from German publication no. 28 06 234 a circuit is known to a telephone system, where each storage station has a storage, in which the call number of a calling station in vain can be entered and from which this dialing number may be indicated to enable a subscriber of a dialed voice station to inform itself of the number and dialing numbers of the dialing stations which had dialed in vain. However, such a circuit would only be conditionally usable 15 respectively. even harmful in the application object.

English Patent Specification No. 20 19 698 and German Patent Publication No. 29 15 909 also relate to a telephone number store with indicating means in which an incoming call after a predetermined period of time when the call is not received and a circuit for automatic answering and acquisition of the phone number is activated. Here, too, what was stated about the aforementioned circuit applies. With the selection equipment according to the invention, it is achieved that with the establishment, by modification or by the development of emergency call systems, the consumption of technical personnel, the switching technical supply and the time consumption are greatly reduced. The equipment according to the invention is more user-friendly and service-friendly, and it also offers fewer manipulation possibilities. After locating the site, it can be uncomplicated to check whether the data entered is correct.

In the following, the invention is described on the basis of an application example in the form of an emergency call system.

When a further subscriber station is commissioned, the automatic dialing device's call number or message store is initially empty. Thus, the station cannot yet perform its function and the 3

is blocked by the connection, for example, as a result of a plausibility check, which means a check of whether the data is plausible, ie. obvious, for example, whether the call number actually consists of 5 digits and a very specific number of digits. A plausibility check for an empty call number or thus, the call store is dropped negatively, which results in the blocking of this station. By means of the telephone, the call number of the exchange is now selected and after the connection has been established, the new establishment of the subscriber station is notified by telephone. It is then appropriate to check the station's mapping and display data in the control panel, respectively. After operating the emergency call key, the subscriber connection line is switched from the telephone set to the subscriber station. From the exchange, the call number of the station to be selected is now transmitted, respectively, the call station's know-how and input of the transmitted information into the storage device of the selection device. For the transfer of storage information 20, a conventional remote control telegram format can be used. After locating the subscriber station, the subscriber station is fully functional and the optionally built-in intercom can be used for communication with the exchange. By means of a decoupling procedure, the connecting ice is decoupled from the central station. In addition, a new operation of the emergency call key advantageously activates the subscriber station, which now automatically selects the programmed call number and after building the information connection 30 with the station to be selected (the emergency call center, if the call number does not necessarily have to correspond to that of the call center). number), an emergency call telegram is included which includes the station and subscriber ID. Thereby, there is an opportunity for a central control of the operation of the subscriber station and of its centrally stored data sets. The commissioning is then centrally logged.

In the case of local area network switches, by expanding the central connection lines (to increase availability), etc., the dialed call number must be changed in the dialer on the subscriber page. To this end, the 5 switchboard can be reached in both the old and the transitional period. and on the new call number. For emergency calls arriving during this period, advantageously before the emergency call connection disconnection according to the invention is changed either automatically or by means of a central operator the call numbers 10 and the identification bearings, respectively. To check the correct operation, emergency call subscribers are then prompted to trigger a control emergency call again.

The subscriber stations that do not register at the exchange during an emergency call are invited by this telephone by 15 to operate their emergency call key for the purpose of changing the stores.

If direct access and short-term buffer storage (RAM) stores are used as call number or known storage, respectively, a sustained plausibility check of the storage contents is necessary because the contents of the storage may have changed after a voltage drop. A negative result of this plausibility check is indicated as a disturbance to the subscriber upon which it must call the exchange.

In a further development of the invention, advantageous are used as call number and identification bearings, not volatile bearings, but electrically changeable bearings (EAROM).

In a further development of the invention, the interconnection requirement between the subscriber station and the central station for entering or changing the dialing number or dialing respectively in the dialing device of the subscriber station is built from the central station. At the subscriber station there is a call receiver which, in a similar way as a call answerer, does not automatically switch to the earpiece within a few seconds.
