The unit is coupled to the inner transmission channel for evaluation of programming instructions from a voice-server, transmitted over the public telephone network, as well as for programming of the configuration data according to the instructions. An Independent claim is included for a voice-server.

Description

The invention relates to a programming device for a configurable telecommunication device according to the Preamble of claim 1 and a voice server according to the preamble of claim 5.

Modern telecommunications systems have a variety of confi configuration options and can be used by the user through appropriate programming to the respective Needs to be adjusted. So it is with a telecommunications nikationsanlage for several devices, for example of assigning individual extension numbers to each end device nen. Furthermore, telecommunications systems often have via an integrated timer that is programmed can be set to the respective local time. The Programming of such telecommunications systems he usually follows by the user who does this via the Keypad of a connected terminal is a complicated one key sequence that is then entered after programming tion from the telecommunication system using acknowledgment tones is answered. The disadvantage here is that the Program requires intensive study of the manual and can only be carried out by trained personnel.

So-called voice servers are also known, which the User configuring a telecommunications location can support. For this, the user dials over the public core intercom network the number of the voice Server, which then provides a welcome text reports and offers various menu options, each are marked with a selection digit. The user chooses then select the desired menu option by using the Ta  field on his or her telephone enter the associated selection number gives.

The voice server then offers a submenu to narrow the problem down or directly transmit the associated announcement to support the user. On this way the user can quickly get to programming Information about the telecommunications system received without having to study a manual for a long time sen. When the connection to the voice server is ended the user can then use the telecommunications system program in a conventional manner. Such Voice servers make it easier to instruct the user, respectively however, the actual programming of the telecommunications university remains cation system left to the user.

The invention is therefore based on the object of a confi Gurable telecommunications device in connection with to create a voice server that is also untrained Allow personnel without prior study of manuals Chen, the configuration of the telecommunications device set in the simplest possible way.

The task is based on a known telecommunications nicationseinrichtung according to the preamble of claim 1, by the characterizing features of claim 1 or - with regard to the voice server - by the characteristics of the contractor Proverb 5 solved.

The invention includes the technical teaching to the Pro programming a telecommunications device Voice server to use the user at the Pro gramming of the telecommunication facility by acousti  cal announcements supported, the user menu-driven is and via the keyboard or the microphone of the tele the desired menu items with the related announcements can finally select to announce the desired configuration setting to get to it, which is then automatically activated by the voice server by transferring appropriate programming commands is set.

The telecommunication device according to the invention has therefore a programming unit on that for setting the desired configuration on the output side with the confi configuration data storage is connected. Is on the input side the programming unit, however, with the internal transfer supply channel of the telecommunications device connected; around the programming commands transmitted by the voice server to be able to record.

The transmitted programming commands processing from the voice server to the Telekommunikationseinrich preferably consist of a plurality of DTMF dial tones (M honest F requenz- V out) depending but it is also possible to programming commands of high frequency sounds at the upper limit of the Übertragungsban of to assemble, which are hardly perceived by the user of the telecommunications device.

In an advantageous variant of the invention, the Te lecommunicationseinrichtung a signal switch on the official side on that in configuration mode announcements from the Voice server forwards to a speaker, whereas the Programming commands of the voice server one with the configu ration data storage connected programming unit leads. This advantageously prevents  the programming commands of the voice server via the loudspeaker cher the telecommunications device are issued.

In the preferred embodiment of this variant is too In addition, an evaluation unit is provided, which the Initiation of configuration mode detects and the signal ver ver in the operating state described sets, whereas the signal switch in normal operation no signals were forwarded to the programming unit, incorrect programming due to random signals to prevent.

The term telecommunication device is here and in the following to be understood generally and not to the one gangs mentioned telecommunications systems limited, the enables the connection of several telecommunication terminals lichen. The term telecommunication device includes rather also telecommunication terminals and intermediaries agencies that are not operated by the end user become. Crucial for the meaning of this term in The scope of the present invention is only that Telecommunication device is configurable and one Has configuration data storage.

For storing several context-specific announcement texts the voice server has a storage element which at for example as an integrated circuit (RAM, ROM, EPROM) can be executed. However, it is also possible to eat the announcement texts a conventional sound carrier, such as using a compact disc on which the individual announcement texts are saved and targeted can be accessed.  

The announcement texts can already be in the storage element can be saved as an acoustic sequence, whereby the Requirements for the speech generator can be reduced because this then only the stored acoustic sequence must play through the speaker. Especially with egg ner realization of the memory element as an integrated However, circuitry may be due to the fact that compared to compact discs lower storage capacity may be advantageous throughput text not as an acoustic sequence, but in text form save. In this case, the speech generator receives as Input signal the respective announcement text and generated from this a corresponding acoustic sequence, which over the Speaker is output.

In addition, the voice server has a control unit on, each one stored in the storage element Select the announcement text and the speech generator accordingly controlled for acoustic output of the selected sequence, the user selecting the announcement text via the Can control input unit. So each announcement text in usually several menu items that make up the user then select a menu item by making an appropriate entry can choose, whereupon the associated announcement text selected and output through the speaker. By this menu-driven user guidance can be too much fetch problems announcement texts, whereby to the finally set the desired configuration Programming command as an acoustic signal from the Voice server transmitted to the telecommunications device becomes.

Other advantageous developments of the invention are in the subclaims or are identified below  along with the description of the preferred embodiment the invention with reference to the figures. It shows gene:

Fig. 1 as a preferred embodiment of the invention, a telecommunications system having a plurality of terminal devices th as a block diagram,

Fig. 2 as a further embodiment of the invention, a configurable phone as a block diagram and

Fig. 3 is a block diagram of a voice server according to the invention.

The telecommunication system 1 shown in FIG. 1, as the core of a conventional switching device 2, which can be allows the connection of up to four analog phones 3.1 to 3.4 and is connected to the public telephone network through a maximum of four trunks. In this case, the switching module 2 provides a large number of switching and convenience functions, such as, for example, exchange rate, internal calls and call diversion under the connected telephones 3.1 to 3.4. The refreshes elle configuration of the telecommunication system 1 is in this case by a PRE-configuration data memory 4 surrounded on which the switching device 2 accesses via an address and data bus.

Between the individual telephones 3.1 to 3.4 and the Ver averaging block 2 is arranged in each case 5.1 to 5.4 connecting the telephones 3.1 to 3.4 in normal operation directly with the service module 2, a signal splitter. In the other position of the signal switch 5.1 to 5.4 , the switching module 2 is bypassed, however, in order to carry out a configuration of the telecommunications system 1 by an external voice server which is dialed via the public telephone network. For this purpose, the user enters the key sequence "* 123 #" on one of the connected telephones 3.1 to 3.4 in order to switch the telecommunications system 1 into configuration mode. In the following it is assumed that the user wants to configure the telecommunication system 1 from the telephone 3.1 , but the configuration is possible in the same way from each of the connected telephones 3.1 to 3.4 . The telephone 3.1 converts the key sequence "* 123 #" into a sequence of DTMF tones (multi-frequency method) which are transmitted to the telecommunications system 1 , each of the telephones 3.1 to 3.4 being assigned an evaluation unit 6.1 to 6.4 , which continuously checks the incoming DTMF tones from the telephones 3.1 to 3.4 and switches the associated signal switch 5.1 to 5.4 with the key sequence "* 123 #" into the configuration mode, so that the following signals are not routed via the switching module 2 . By bypassing the switching module 2 in the configuration mode, it is ensured that the switching module 2 is not disturbed by the subsequent input from the user during the configuration. Instead, the signal switch 5.1 connects the phone 3.1 in configuration mode via a wide re signal switch 7 with a switching matrix 8 , which is the switching module 2 upstream of the office. In normal operation of the telecommunications system 1 , this switching matrix 8 transparently connects the switching module 2 to the exchange lines. In configuration mode, however, the switching matrix 8 serves to find a free exchange line and to connect it to the telephone 3.1 via the signal switches 7 , 6 , 5.1 .

Furthermore, the telecommunications system has a dialing circuit 9 , which is connected on the output side to the switching matrix 8 and is activated by the evaluation unit 6.1 when the key sequence "* 123 #" arrives and then dials the external voice server by using appropriate DTMF dialing tones via the Trunk line are transferred.

After the connection to the external voice server has been established, the user first answers with a welcome text and the announcement of menu options, each of which a selection number is assigned, whereby the user is asked to select the desired menu option, the associated number on the keypad of the Phone 3.1 . The announcements are transmitted to the telephone 3.1 bypassing the switching module 2 via the switching matrix 8 and the signal switches 7 , 5.1 and acoustically output via its loudspeaker. The user then presses the desired number key on the keypad of his telephone 3.1 , whereupon a corresponding DTMF tone is transmitted to the voice server via the signal switches 5.1 , 7 , the switching matrix 8 and the public telephone network. The voice server evaluates the incoming DTMF tones and then issues an announcement on the desired menu option, the announcement in turn being transmitted to the telephone 3.1 via the public telephone network and being output acoustically via its loudspeaker.

By repeatedly selecting one of the menu options offered by the voice server, the user can thus determine the configuration parameter that is to be changed. Then the voice server asks for the desired value of this configuration parameter, whereupon the user enters a corresponding sequence of digits on the keypad of the telephone 3.1 , which defines the value of the configuration parameter. The voice server repeats the entered value and asks the user for confirmation. The user then presses either the pound key "#" to confirm the entered value or the star key "*" to reject the entered value.

Upon confirmation by the user, the voice server transmits a programming command consisting of several DTMF tones to the telecommunication system 1. This programming command is transmitted via the switching matrix 8 to the signal soft 7 , which filters out the DTMF tones of the programming command and selectively a programming unit 10 which is connected on the output side to the configuration data memory 4 . The signal switch 7 thus prevents the DTMF tones of a programming command from being forwarded to the telephone 3.1 so that the user only hears the announcements of the voice server, but not the unintelligible and therefore disturbing DTMF tones of the programming commands. The programming unit 10 then interprets the programming commands and programs the configuration data memory 4 in accordance with the desired change.

Fig. 2 shows a configurable telephone 11 with a conventional telephone circuit 12 , which provides a variety of convenience functions, such as repeating calls, speed dialing and name storage. The current configuration of the phone 11 is stored in a configuration data memory 13 on which the phone circuit 12 accesses via an address bus and a data bus. The telephone circuit 12 is connected to a keypad 14 for entering the number to be dialed and for configuring the telephone 11 . In addition, the telephone circuit 12 is connected in a conventional manner with a microphone 15 , a speaker 16 and an LCD display 17 .

The telephone 11 is configured in the manner described above by an external voice server. For this purpose, the user first enters the key sequence "* 123 #" on the keypad 14 in order to put the telephone 11 into the configuration mode. The telephone circuit 12 then outputs corresponding DTMF dialing tones, which are recognized by an evaluation unit 18 . The evaluation unit 18 then activates a selector circuit 19 , which selects the voice server independently. After the connection to the voice server has been established, the latter reports in the manner described above with a welcome announcement and various menu options from which the user can select a menu option by entering the associated selection number via the keypad 14 . The announcements of the voice server are transmitted from a signal switch 20 to the telephone circuit 12 and output via the loudspeaker 16 . After the selection of the desired configuration parameter and the desired value, the voice server then transmits a corresponding programming command in the form of several DTMF tones to the telephone 1 , the DTMF tones coming from the voice server being selective from the signal soft 20 a programming unit 21 are supplied. In configuration mode, the signal switch 20 thus forwards announcements coming from the voice server to the telephone circuit 12 , whereas programming commands from the voice server are selectively fed to the programming unit 21 . This prevents the DTMF tones of the programming commands coming from the voice server from being output via the loudspeaker 16 , since this would disturb the user.

Fig. 3 finally shows a block diagram of a voice server 22 , which he can be reached via the public telephone network 23 and enables voice-guided remote configuration of the telecommunication devices described above. The operation is controlled by a control unit 24 , which evaluates the incoming DTMF tones and reads the corresponding announcement texts from a hard disk memory 25 , which are then fed to a speech generator 26 and transmitted via the telephone network 23 to the telecommunications device. After determining the desired configuration parameter, the control unit 24 then reads the associated programming command from a further memory 27 , which is stored as a sequence of digits. This sequence of digits is then supplied by the control unit 24 to an MVF generator 28 which generates the corresponding DTMF tones and transmits them via the telephone network 23 to the telecommunications device to be configured.

The invention is not limited in its execution the preferred embodiments given above le. Rather, a number of variants are conceivable, which fundamentally different from the solution shown makes use of any type.
