Ledningsgruppering vid sokar- och/eller ledningsvaljarenhet i en telekommunikationsanlilggning. Line grouping at a search and / or line selector unit in a telecommunication installation.

Rireliggande uppfinning hanfor sig till en snare- och/eller ledningsvaljarenhet, som är uppb.7„,ggd av tya eller flera delvaljarsteg och dar abonnentledningar eller liknande ledningar aro anslutna till faltkontakter i det forst liggande (primara) valjarstegets yaljare. De till sagda valjarenhet anslutna abonnentledningarna arc kopplade till en faltkontaktgrupp i ett flertal valj are, varvid atminstone en av dessa med varandra multiplicerade valjare i silt kontaktfalt uppyisar andra abonnentledningar an atminstone flagon av de Ovriga i multipliceringen inghende valjarna. En pa detta stilt utford koppling ãr kand och kallas i det foljande for ordningsvaxlad koppling. (Kopplingen skiljer sig fran en sokargradcring darigenom, ,att valjarnas kap acitet dr oforandrad.) Med »ordningsvaxlad koppling» forstas i enlighet med tidigare definitioner en sadan skruvad gradering, dar antalet i olika hand uppsokta utgangsvagar àr ofora.ndrat och med en»enkelt ordningsyaxlad koppling» forstas, att skruyningen iir sh .anordnad, att rader och kolumner kunna anses ha bytt plats i primarvaljarnas kontaktfalt. En dylik skruvning betecknas aven son]. 900:s vridning En .ordningsvaxlad koppling for t. ex. 100 nummer kan utfdras genom att man numrerar ledningarna i lopande foljd (00-99) och ordnar dem i tva slag ay talgrupper (tio entalsgrupper med entalen 0-9 och i tic tiotalsgrupper med tiotalen 0-9). Ledningarna kunna sedan multipliceras pa sadant satt, att en viss ledning (t. ex. 09), dels uppkopplas tillsammans med Ovriga ledningar med samma tiotal som ledningens tiotalssiffra (01, 02, 03, 04 etc.), dels tillsammans med &riga ledningar med samma ental som ledningens entalssiffra (19, 29, 39, 49 etc.). En pa detta suit utford ordningsvaxlad koppling kallas i det foljande for en enkelt ordningsvaxlad koppling. Del bor observeras att vid anyandandet av icke-dekadiska grupperingar kan enkelt ordningsvdxlad koppling astadkommas med mindre an 100 nummer (t. ex. 5 - ledningar). Vid en enkelt ordningsvaxlad koppling behoyer yaljarnas kapacitet ej vara lika stor som antalet i en vallargrupp arbe- tande valjare. Sa t. ex. kan man anordna en enkelt ordningsvdxlad koppling Mr 200 led- ningar genom att lata 10 valjare med kapaci- teten 20 uppsoka ledningar med i ena fallet yar sin gemensamma entalssiffra och i andra fallet var sin gemensamma tiotalssiffra under det att hundratalssiffrorna arc 0 och 1 i samtliga valjare. The present invention relates to a snare and / or line selector unit, which is composed of ten or more sub-selector stages and where subscriber lines or similar lines are connected to field contacts in the first (primary) selector stage radiator. The subscriber lines connected to said selector unit arc are connected to a field contact group in a plurality of selectors, at least one of these multipliers multiplying in silt contact field indicating other subscriber lines than at least a flag of the Other selectors in the multiplication. One of these posed challenge couplings is known and is hereinafter referred to as order-switched coupling. (The coupling differs from a so-called grading ring in that the voters' capacity is unchanged.) "Order-switched coupling" means, in accordance with previous definitions, such a twisted grading, where the number of output-weighted output weights is unchanged and with a "simple order-shafted coupling »means that the screwing is arranged so that rows and columns can be considered to have changed place in the contact field of the primary selectors. Such a screw is also referred to as son]. 900's rotation A .ordshifted coupling for e.g. 100 numbers can be performed by numbering the wires in consecutive order (00-99) and arranging them in two kinds in number groups (ten singular groups with the numbers 0-9 and in tens groups with the numbers 0-9). The wires can then be multiplied in such a way that a certain wire (eg 09) is connected together with Other wires with the same tens as the wire's decimal digit (01, 02, 03, 04 etc.), and partly together with other wires with the same singular as the singular number of the line (19, 29, 39, 49, etc.). An order-switched coupling on this suit is hereinafter referred to as a single-order alternating coupling. It should be noted that when using non-decadent groupings, a simple order-switched connection can be achieved with less than 100 numbers (eg 5-wires). In the case of a simple order-switched connection, the capacity of the yaljar does not have to be as large as the number of voters working in a group of herds. In e.g. you can arrange a simple order-connected connection Mr 200 wires by letting 10 selectors with the capacity 20 seek out wires with in one case yar their common singular digit and in the other case each their common tens digit while the hundred digits arc 0 and 1 in all valjare.

Uppfinningen kannetecknas i huyudsak claray, att de numrerade ledningarna med hansyn till kapaciteten hos kontaktfalten I det forstliggande delvaljarsteget aro anslutna till kontaktfalten pa sadant salt, att till -mile valjargrupp anslutna numrerade ledningar ha atminstone en siffra (hundratals-, tiotalseller entalssiffra) gemensam och att varje numrerad ledning dr ansluten till kontaktfal- ten i atminstone tva valjargrupper i det forstliggande delvaljarsteget, vilkas numrerade ledningar ha olika gemensamma siffror (salunda kan t. ex. en numrerad leclning upps5- kas i fyra yaljargrupper, av vilka tva ha gemensam hundratalssiffra, en har gemensam tiotalssiffra och en gemensam entalssiffra). The invention can be characterized in particular claray, that the numbered wires with regard to the capacity of the contact field In the first sub-selection stage are connected to the contact field on such salt, that numbered wires connected to -mile group of voters have at least one digit (hundreds, tens or singular digits) in common and each numbered wire is connected to the contact fields in at least two voter groups in the first sub-voter stage, whose numbered wires have different common numbers (thus, for example, a numbered line can be found in four yaljar groups, two of which have a common hundred digit number, one have a common decimal digit and a common singular digit).

Fig. 1 visar en trafikvagsplan for en enligt uppfinningen utford valjarenhet fill. 1000 nummer och fig. 2 visar huru den ordningsvaxlade kopplingen enligt uppfinningen kan vara utford i sagda yaljarenhet. Fig. 1 shows a traffic plan for a selector unit fill according to the invention. 1000 number and fig. 2 shows how the order-switched coupling according to the invention can be challenged in said yaljar unit.

Fig. 3 visar en forenklad ordningsvaxlad koppling, som ej medger lika god utnyttjning av valjarna, men som i stallet mojliggOr en enklare och mera symmetrisk utformning av valjarenheten. Fig. 3 shows a simplified order-switched coupling, which does not allow equally good utilization of the selectors, but which instead enables a simpler and more symmetrical design of the selector unit.

I fig. 1 visas en &War- och/eller ledningsvaljarenhet, som bestax av 40 primara koor- dinatvaljare, som aro ordnade i tio kolumner (I-- X) med fyra koordinatvaljare 1-4 i varje kolumn samt fyrtio sekunddra koordinatvaljare likaledes ordnade 1 tio kolumner (I—X) med fyra koordinatvaljare 1-4 i varje kolumn. A.Y de primara koordinatvaljarna visas de, som ligga i forsta och andra kolumnen (101, 111, 121, 131 resp. 102, 112, 122 och 132), saint de som ligga i sista eller tionde kolumnen (110, 120, 130, 140). De daremot korresponderande sekundarvaljarna dro resp. 141, 151, 161, 171 och 142, 152, 162, 172 och 2— -- 150, 160, 170, 180. Samtliga koordinatvaljare forutsfittas ha tio stang- och tio bryggmagneter. Fig. 1 shows a & War and / or command selector unit, which consists of 40 primary coordinate selectors, which are arranged in ten columns (I-- X) with four coordinate selectors 1-4 in each column and forty second coordinate selectors also arranged 1 ten columns (I — X) with four coordinate selectors 1-4 in each column. In the primary coordinate selectors, those in the first and second columns (101, 111, 121, 131 and 102, 112, 122 and 132, respectively) are displayed, as are those in the last or tenth column (110, 120, 130, 140 ). The corresponding secondary selectors, on the other hand, drew resp. 141, 151, 161, 171 and 142, 152, 162, 172 and 2— - 150, 160, 170, 180. All coordinate selectors are fitted with ten rod and ten bridge magnets.

I fig. 2 visas i en numreringsplan huru den ordningsvaxlade kopplingen ar anordnad vid en valjarenhet enligt fig. 1. Den ordningsvaxlade kopplingen av abonnentledningarna bar utforas sa, att en bestamd godtyckligt vald abonnentledning fir ansluten till valjarna (bryggmagneterna) tillsammans med majligast olika abonnentledningar i var och en av de 4 bryggmagneterna. Fig. 2 shows in a numbering plan how the order-switched connection is arranged at a selector unit according to Fig. 1. The order-switched connection of the subscriber lines should be made so that a certain arbitrarily selected subscriber line is connected to the selectors (bridge magnets) together with most different subscriber lines in each of the 4 bridge magnets.

Man kan vid har visade enkelt ordningsvaxlade kopplingar med ettusen abonnentledningar erhalla fyra valj are, sonn uppkoppla en viss abonnentledning tillsammans med hell skilda avriga abonnentledningar. (Vid 100 nummer finnas vid dekadisk gruppering endast tva dylika valjare.) Den ordningsvaxlade kopplingen har i fig. 2 utforts sa, att de i f8rsta och andra hand uppsokta koordinatvaljarna bestammas av abonnentledningens hundratalssiffra, de i tredje hand upps8kta koordinatvaljarna av dess tiotalssiffra oeh de i fjarde hand uppsokta kordinatvaljarna av dess entalsiffra. It is possible, in the case of simple, alternately connected connections with one thousand subscriber lines, to obtain four selectors, and to connect a certain subscriber line together with completely different other subscriber lines. (In the case of 100 numbers, there are only two such selectors in decadent grouping.) The order-switched connection has been made in Fig. 2, so that the coordinate selectors sought in the first and second place are determined by the number of subscribers in the subscriber line, the coordinate selectors of the tens digit and in the fourth hand, the coordinate selectors of its singular digit.

Med hansyn till kopplingstekniska svarigheter är det emellertid battre att utfora ordningsvaxlingen enligt fig. 3. De i forsta, andra och tredje hand uppsokta valjarna aro har anslutna till olika abonnentledningar. Den. i fjfirde hand uppsokta valjaren är ansluten till samma ledningar som den i forsta hand uppsokta valjaren. With regard to switching technical responsibilities, however, it is better to perform the order change according to Fig. 3. The selectors aro in the first, second and third hand are connected to different subscriber lines. The. the fourth-hand-selected selector is connected to the same wires as the first-hand-selected selector.

Den ordningsvaxlade kopplingen i fig. 3 fir utford pa sadant sat% att de t. ex. i forsta och andra hand uppsokta koordinatvaljarna ha samma hundratalssiffra och de t. ex. i tredje och fjarde hand upps8ka koordinatvaljarna ha samma entalssiffra. De koordinatvaljare, som ombesorj a uppkoppling till ett visst nummer kunna foljaktligen uppsokas parvis sa, att man erhaller 20 grupper av primara och tillhorande sekundara koordinatvaljare. De I fjfirde hand uppsokta valjarna (bryggmagneterna) aro hàr anslutna till samma nummer, som de i forsta hand uppsokta valjarna. The order-switched coupling in Fig. 3 is challenged in such a way that they e.g. in the first and second hand, the coordinate selectors have the same hundreds digit and the e.g. in the third and fourth hand, the coordinate selectors look for the same singular number. The coordinate selectors which provide connection to a certain number can consequently be searched in pairs, so that 20 groups of primary and associated secondary coordinate selectors are obtained. The fourth-choice selections (bridge magnets) are connected here to the same number as the first-selected selections.

Den ordningsvaxlade kopplingen omfattar samtliga till valjarenheten intagna abonnentledningar d. v. s. 1000 nummer. Ett visst abonnentnummer t. ex. 909 uppsokes i en grupp av koordinatvaljare, som innehaller de primara koordinatvaljarna 110 och 120, varvid sagda grupp as koordinatvaljare bestammes av hundratalssiffran 9. De bryggmagneter, som kunna uppkoppla ifragavarande nummer i de bagge primara koordinatvaljarna, bestammas av numrets entalssiffra 9 resp. tiotalssiffra 0. I en annan grupp koordinatvalj are uppsokes numret i de primara koordinatvaljarna 130 och 140, varvid sagda grupp av koordinatvaljare bestammas av entalssiffran 9 och de primara koordinatvaljarnas bryggmagneter be- stammas av tiotalssiffran 0 resp. hundratalssiffran 9. The order-switched connection comprises all subscriber lines connected to the selection unit, i.e. 1000 numbers. A certain subscriber number e.g. 909 is searched in a group of coordinate selectors, which contains the primary coordinate selectors 110 and 120, said group as coordinate selectors being determined by the hundred digit 9. The bridge magnets, which can connect the respective numbers in the primary primary coordinate selectors, are determined by the singular number 9 of the number. In another group of coordinate selectors, the number in the primary coordinate selectors 130 and 140 is searched, the said group of coordinate selectors being determined by the singular digit 9 and the bridge magnets of the primary coordinate selectors being determined by the decimal digit 0 and 0, respectively. the hundred digit 9.

Uppfinningen kan givetvis varieras pa ett flertal salt utan att den barande uppfinningstanken dunned frangas. The invention can of course be varied on a plurality of salts without compromising the underlying inventive concept.

Vid den i fig. 1 visade trafikvagsplanen har forutsatts att kapaciteten hos valjarenheterna I sista gruppvaljarsteget ãr sa stor att gruppvaljarna kunna utfora numeriskt val over 100 vior utan att sokningskapaciteten darfor blir otillracklig. Ledningsvaljarenheten kan emellertid aven utfaras sa nit den kan samarbeta med grupp-valjarenheten med liten sokningskapacitet. In the traffic wagon plan shown in Fig. 1, it has been assumed that the capacity of the selector units in the last group selector stage is so large that the group selectors can perform numerical selections over 100 vior without the search capacity therefore becoming insufficient. However, the line selector unit can also be designed so that it can cooperate with the group selector unit with a small search capacity.

Man kan salunda ansluta de yttre forbindelseledningarna for ankommande trafik till ett sist liggande tredje delvaljarsteg, som kan betraktas som ett numeriskt valjarsteg. En ankommande ledning anslutes till en valj are (bryggmagnet) i detta sist liggande dclviiijarsteg pa sadant satt att denna valj are har mojlighet att na vilken som helst av de i samma rad i fig. 1 liggande sekundara koordinatvaljarna (141-150 resp. 151-160 resp. 161-170 resp. 171-180). The external connecting lines for oncoming traffic can thus be connected to a last third partial selection stage, which can be regarded as a numerical selection stage. An incoming line is connected to a selector (bridge magnet) in this last dlviiijar stage in such a way that this selector has the possibility of reaching any of the secondary coordinate selectors (141-150 and 151-, respectively) lying in the same row in Fig. 1. 160 and 161-170 and 171-180, respectively).

De inre forbindelseledningar, som via ett ledigmarkeringsrela •erhalla lystringspotential, pfiverka ett mot varje -valjargrupp i det tredje valjarsteget svarande ledigmarkeringsrela, varvid detta rela foranleder att lystringspotential utsandes a de yttre forbindelseledningar, som aro anslutna till sagda valjargrupp. Uppkopplingen av valjarna i detta tredje delvaljarsteg sker genom direktinslag pa samma satt som visats vid tivriga delvaljarsteg. The internal connecting lines, which receive a listening potential via a release marking relay, actuate a release marking relay corresponding to each voter group in the third election stage, this relay causing the listening potential to be transmitted to the outer connecting lines which are connected to said selection group. The connection of the voters in this third sub-electoral step takes place through direct input in the same way as shown in other sub-electoral steps.

For att bibehalla mojligheten att samtidigt kunna uppkoppla flera ankommande anrop maste man ordna sa, att lystringspotential endast utsandes till de yttre forbindelseledningar, som ga till den grupp av gruppyaljarenhater, som aro anslutna till en viss till manaveranordningen inkommande ledning. In order to maintain the possibility of being able to connect several incoming calls at the same time, it must be arranged that listening potential is only transmitted to the external connecting lines, which went to the group of group callers, which are connected to a certain line incoming to the control device.

Det tredje delvaljarsteget kan aven anordnas som ett separat valjarsteg. Valjarsteget kan majligen betraktas som ett forvaljarsteg, enar den numeriska installningen ombesorjes av ledningsvaljarenheten, sh att valjarna i har betraktade valjarsteg ej behOva fOrses med nagra organ far numerisk uppkoppling. The third sub-election step can also be arranged as a separate election step. The selector stage can possibly be regarded as a preselector stage, provided that the numerical installation is taken care of by the line selector unit, so that the constituents in the constituency stages considered do not need to be provided with any means for numerical connection.

Ledningsvaljarenheten eller sokar- och ledningsvaljarenheten kan aven arbeta som en ledningsvaljare for gruppnummer i det att man genom att taga ett visst gruppnummer kan foranleda -vissa till gruppnumret h8rande abonnentrelder att Over en utbrytningskedja utpeka en ledig abonnentkdning och via sina grupprelaer ange ifragavarande abonnentlednings nummer sa att uppkoppling kan ske. The line selector unit or the pager and line selector unit can also work as a line selector for group numbers in that by taking a certain group number one can cause -some subscribers belonging to the group number to designate a free subscriber chain over an outbreak chain and via their group relays to indicate subscriber numbers connection can take place.

Man kan aven lata t. ex. gruppvaljarenheten. uppsoka de olika gruppnummerviorna och kan sedan delge gruppvaljarenheten den lediga abonnentledningens nummer genom att pa kant salt lata en f Or stationen gemensarn — —3 impulsandare oversanda de numeriska installningsigrialerna till valjarenheten. Harigenoin erhaller man mojlighet att placera ledningar med samma gruppnummer i olika ledningsvaljarenheter. You can also be lazy e.g. the group selection unit. seek out the various group number lines and can then communicate the number of the free subscriber line to the group selection unit by letting a single impulse transmitter send the numerical installation signals to the selection unit. Harigenoin gives you the opportunity to place lines with the same group number in different line selection units.
