SWITCHING CONFIGURATION FUR CENTRALSTEERED TELEPRINTER CHOICE SWITCHING PLANTS WITH CENTERS A ROUND WRITE MECHANISM

The invention refers to a switching configuration for centralsteered Fernschreibwählvermitrlungsaulagen with a central over the switching matrix attainable round write mechanism, in some round write framework, a string device, a Bewerter and for the setting up the Informaüonen taking up register s necessary sent by the participant in sequential consequence of round write connections is present and which Rundschreibelnrichtung is at the input side over a special service number sent by evaluation by the participant in the ventralen control provable going arranged transmission selectable and at the output over a number of coming arranged transmissions to the central control turn onable, whereby for the connection establishment of the central control the information contained in the register of the round write mechanism for order stands. F.s is for a long time well-known, which offer the possibility to attached participants to a teleprinter selecting switching plant for the setting up from Rundschreibund Konferengverbindungen u. While a round write connection is the connection developing calling participants able, its message to several called participants ab2usetgen, without however the called participant taken part in the circular thereby for their part a M0glichkeit have to send back messages to the calling is participant. While a conference call against it the called participants taken part in it receive but can not only the message sent by the calling participant, for their part also messages send, which will receive both from the calling participant and from all different at the conference call called participants taken part. The structure of round write connections takes place over a round write mechanism existing in the switching center. This can if also conference calls to be possible be supposed, by one it assigned conference switching device supplement. In connection with the structure of Rundschreibund conference calls result however some problems. Since into well-known switching plants the conference switching devices are separate either from the round write mechanisms, are attainable thus over different call numbers or are turned on to the Rundschreibeinriehtung by means of switching bridges, the calling participant can develop either only one round write connection or only one conference call. A further problem consists of that in the context of a conference call from the called participants to the calling participant sent messages developing the conference call from all at the conference call Teiinehmern taken part will receive. It st neither possible to send a message outgoing from the calling participant only at one only the called participant taken part in the conference call is possible still it to send from one an only the called participant taken part in the conference call sent message only to the calling participant. The invention is the basis the task to indicate a switching configuration with which these s of disadvantages are avoided. In particular the task of the invention consists of giving to the participants the possibility on the basis of the structure of a round write connection of accomplishing after the DE-PS Nr.1762761 = AT-PS Nr.294206, a change to conference calls and within a conference call again a change to different kinds from conference calls. In accordance with invention by it reached that by the calling participant place after the structure of a round write connection from given in each case combinations of Fernschreihzeichen formed criteria for the production of a full conference call, with the all Teiinehmerstellen involved receive all message, for production half conference, at which the involved the sent are sendable the message by the participant places only in each case from the calling participant place or for the production of a partial conference call, with which both the messages sent by the calling participant place will receive only from a certain Teiinehmerstelle and from this sent message only from the calling Teiinehmerstelle, that the Rundsehreibeinrichtung for the evaluation of the understanding criteria is furnished and that with statement one of these criteria in the Rundschreibeinriehtung one the round write mechanism assigned conference switching device according to the kind of the conference call requested in each case so (Vollkonferenzbzw. Halbkonferenzbzw. Partial conference call) adjustable and into the communications is capable of being activated. Thus that the calling participant develops first a round write connection and that only D is manufactured nn by evaluation additional vem calling participant of sent criteria in form of certain Nr.342121 teleprinter combinations the conference call, it is it the Teiluehmern in simpler way than so far possible to develop alternatively Rundschreiboder conference calls. Beyond that the use of special criteria offers the favourable possibility, the different forms of conference calls such as full of manufacturing Halbund partial conference calls. It is, if as criteria for a round posting, a full conference, Halbkonferenzund partial conference call of the calling participant place is sendable in each case a certain letter combination to the central Rundschreibeinrich ung, after evaluation of these criteria in favourably evaluates the Rundschreibelnrichtung over the round write frameworks the multi address call equipment is switch offable, and to the confirmation of the evaluation and appropriate Umsehaltung in the agreed upon connecting kind, accomplished there, the same Buehstabenkombination to the calling participant is send backable. So that connected advantages consist of that on the one hand with the participants themselves additional operating controls are not necessary and on the other hand that the Textbewerter and Textsender already existing in round write mechanisms can be shared. Finally it is favourable, if the criteria are fiir full conference, Halbkonferenzund partial conference call participant characteristic choice information involved by the calling participant immediately after sending those the outer connection sendable, or if the Kriterlen for full conference, Halbkonferenzund is sendable partial conference call from the calling participant to arbitrary times during the existence of a connection. The associated advantages exist to change therein that the calling participant can change the momentary connecting kind at each time of a conference call, thus for example from a full conference call on a Halbkonferenzoder partial conference call can. A further appropriate arrangement of the invention consists still of the fact that during the duration in R hroen the partial conference call existing single connection of the round write mechanism to the participants a queuing code not taken part in it is sendable and that for the completion of such a single connection the criterion for a Teilkonferen2verbindung, sent again by the calling participant, is evaluable. Details of the invention are described in the following on the basis the designs. Show: Fig.1 in form of a Bloekschaltbildes a possible remark example of the invention; Fig.2 in schematic representation the temporal operational sequence of a full conference circuit with change-over on a normal round write connection; Fig.3 this expiration for the case of a Halhkonferenzverbindung and Fig.4 the expiration for the case of a partial conference call. In Fig.1 the parts of a centralsteered switching plant with a round write mechanism, substantial for the understanding of the invention, are represented. It is accepted that a calling participant, in the following main part takers --HTN-- called, a connection to several Teiinehmern 3S --TNI to TNn-- to construct wants. In addition the main part taker sends --HTN-- a criterion for the setting up a Rundsohreibverbindung out, that arriving in the switching center over those occupied transmission --Uek-- and a register coupler --OK ONE -- into a central register --R-- arrived. Over a central control --ZES-- becomes a switching matrix --WNW-- in such a manner adjusted that the main part taker --HTN-- over going an arranged transmission --Ueg-- with a Rundscbxeibeinrichtung --RH-- is connected. Of the main part taker --HTN-- sent choice information, for the participants taken part in the connection --TNI to TNn--, become over a staticizer --SPU-- and a Textbewerter --German Federal Armed Forces-- into a round write register --RRg-- taken over. The Bewerter --German Federal Armed Forces-- thereby Prüfaufgabcn essentially takes over. Thus e.g. both the round write authorization of the participants and each intake can end to selection signals to be examined. Over the exits --1 to n-- a Rundschreibrnhmens --RR-- become those coming arranged transmissions --Uekrl to Uekrn-- occupied and over the register coupler --RK-- ieweils a Regäster --R-- turned on. Over a parallel series converter --PSU-- and the round write frameworks --RR--become contents of a round write register --RRg-- into the registers --R-- taken over. The central control --ZESin of the switching center steers the structure of the connections between the main part taker --HTN-- and the participants taken part in the circular --TN1 to TNn--. Structure and impact of such an arrangement for the setting up a Rundsehreibverbindung are for example in the DE-PS No. 1762761 descriptive. Nr.342121 of the Hauptteiinehmer --HTN-- can set off now into actually well-known way his message as federal letters. In addition, he can select, as suggested by the invention by sending further criteria a full conference, Halbkonferenzund a partial conference call. Are indicated, as in the context of the invention, when criteria for the individual connecting kinds in each case letter combinations uses, which do not occur in the text otherwise, then the evaluation of these criteria in evaluated can --German Federal Armed Forces-- the Bundschreibelnrichtung --Fuel element-- take place. On the arrival and recognizing these criteria control signals R-S, VK, HK and TK at the Bundschreibr become dependent hmen --RR-- delivered. There the conference switching device becomes --IT-- turned on, in which the appropriate control procedures are then accomplished in actually well-known way. On the basis of Fig.2 now the expiration for a full conference call as well as one describes itself to it following change-over on normal round write enterprise more near. R-S is accepted that the main part taker --HTN-- a connection to the participants --TN1 to TNn-- in well-known way as round write connection developed. As criterion for the change-over into a roll conference call the Hauptteflnehmer sends --HTN-- a closed is group of letters, in the example the group of letters bhbb out. This becomes in the Rundschreäheinrichtung --RH-- received, and leads there to the delivery of the tax criterion --VK-- to the federal write framework. Thus the conference switching device is turned on. At the same time the appropriate Sehalünaßn hmen there accomplished for a full conference call. After change-over in the round write mechanism becomes the main part taker --HTN-- the change-over by return of the group of letters bbbb confirms. Of the Hauptteiinehmer --HTN-- sent group of letters becomes also from all other Teiluehmern --TN1 to TNn-- received, so that information about the following connecting kind is present also there. The Hauptteiluehmer --ttTN-- now a reporting request for first the participant taken part in the conference call sends, for example for the participant --TNI-- out. Also this 2s reporting request becomes from all participants involved --TN1 to TNn-- received. After a defined transmission break --P--, which can amount to for example 1 to 3 s, the first participant sends --TNI-- its text --Tel-- out, that of the main part taker --HTN-- and of all Teiluehmern involved --TN1 to TNn-- one receives. At expiration of a defined transmission break --P-- the main part taker sends --HTN-- the reporting request for the next participant, for example for the participant --TN2-- out. This Vorg'änge repeats itself, until finally also the last Teälnehmer --TNn-- its text --Tan-- sent. The Haupttellnehmer --HTN-- now the transmission can terminate by sending the disconnect signal. In addition, it can switch, as in Fig.2 explained, on normal round write enterprise, over for example all Tellnehmern taken part in the connection an appropriate answer to the texts of the individual participants received from it to 3s convey. In addition the main part taker sends --HTN-- the round write criterion, which is likewise a closed group of letters, in the example the group of letters aaaa out. This becomes both in the round write mechanism --RH-- and with all participants involved --TN1 to TNn-- received. M_it recognizing these Buehstabengruppe in the round write mechanism --RH-- to round write enterprise and this change-over is switched there by return of the Buchstahengruppe aaaa to the Hauptteiluehmer --HTN-- confirmed. The Hauptteiluehmer --HTN-- sends now a concluding text --Txh-- out, that of all participants involved --TN1 to TNnempfangen will direct afterwards to it can the disconnect signal, which is formed in well-known way by the group of letters nnnn, be sent. In the switching center leads into actually well-known way to the completion of the federal letter. 4s in similar way happens the change-over on the mode of operation half conference. On the basis of Fig.3 one recognizes that of the main part taker --HTN-- sent as criterion group of letters agreed upon for the change-over on the mode of operation half conference ecec again of all participants involved --TN1 to TNn-- and in the round write mechanism --RERempfangen becomes. Evaluation and change-over on the desired mode of operation become in the round write mechanism --RH-- accomplished, on which the change-over is confirmed in such a way to the main part taker by return of the group of letters ccce. This sends thereupon the reporting request for a participant involved, e.g. for the participant --TNI-- out. At expiration of a defined transmission break --P-- this begins with sending its text --Tel--, that now however, since it concerns a half conference call, only with the main part taker --HTN-- one receives. In each case at expiration of the defined transmission break, which begins at the end of a text ending, can of the main part taker --HTNein of others the participant taken part in the connection for transmission to be requested. Finally is the last participant --TNn-- for text ending requested and is its text --Tan-- with the Hauptteiinehmer arrived, s knows these a concluding message to all participants involved --TN1 to TNnsenden. It can send in addition, as indicated in Fig.3, immediately the disconnect signal nnnn and the circular in on sees well-known way terminating. A further important mode of operation is the Teflkonferenzverbindung. The procedures running off thereby are described on the basis of Fig.4. The Hauptteiin “more hmer --HTN-- for this purpose again an agreed upon group of letters, in the example the group of letters dddd, sends those with all participants involved as criterion --TNI to TNn-- and in the Rundsehreibeinrichtung --RH-- one receives. After evaluation of the criterion in the round write mechanism and change-over on first half conference enterprise the Hauptteiinehmer the change-over is acknowledged by return of the criterion dddd. Thereupon of the Hauptteünehmer --HTN-- is participants intended sent reporting request for one, e.g. for the participant--TNI o, receives this and all remaining participant. The participant --TN1-- announces itself by return of an indication, e.g. --Le-- (Letter around, attitude). This criterion arrives only at the round write mechanism --RH-- and to the main part taker --HTN--, The evaluation of this criterion in the round write mechanism --RH-- arranges this to switch to partial conference. The taken place around, attitude becomes the main part taker --HTN-- and the participant --TN1-- by forwarding of the Senäeaufforderung--SND--communicated. The participant--TN1-- begins thereupon with sending its text --Txl--, that only of the Hauptteiinehmer --HTN-- one receives. After completion of the text the Hauptteiinehmer can --HTN-- directly for his part, those exclusively send a message from the participant --TN1-- one receives. It is also möE1ich that first the main part taker --HTN-- a text, then only from the participant the 2s sends --TNI-- it is received and that afterwards to it the participant --TN1-- with his message sending begins. The single connection between the Hauptteünehmer --HTN-- and the participant --TN1-- becomes by renewed sending of the group of letters dddd by the main part taker --HTN-- terminated. For each single connection all other participants receive, in the example the participants --TN2 to TNn-- of the round write mechanism ~-RH-- a queuing code --MOM-- attributed. The descriptive procedures can with all participants --TN1 to TNn-- in arbitrary order and to be arbitrarily often repeated. The Haupttei] taker --HTN-- the participant can after exchange of the messages between TC and everyone --TN1 to TNn-- always on another Verblndungsart, e.g. on the mode of operation circulars switch, in order to attribute for example to all participants a message. The completion of the circular is done also here, just like in on the basis of Fig.2 3s and 3 described operational sequence always via the Hauptteflnehmer --HTN--, which sends in addition into actually well-known way the group of letters nnnn. Just as for the Bewermng of the groups of letters the Bewerter existing agreed upon as switching criteria in the round write mechanism serves, can be used also for sending of confirmation criteria, requests to send and queuing codes in the round write mechanism existing string devices. Further all timeout controls, for example in the Rundschreibeinrichtunff, which can be accomplished during a connection, know the monitoring of the transmission breaks with which there already existing circuits are accomplished. The additional relays necessary for it do not represent large additional expenditure. 4s the invention was only described on the basis some selected examples. Of course it lies in the context of the invention to change also during a connection several times the mode of operation to switch thus b “ispieisweise of a Vo] lkonferenzverbindung on a half conference call and to it afterwards to a partial conference call.
