Description

Uppfinnare: M Novotny, J H Rott och J Pekarek Prioritet begtird frdn den 19 ma) 1959 (Tjeekoslovakien) Foreliggande uppfinning hanfor sig till ett satt for overforing av ett valt nummer med hjalp av register, sarskilt vid forbindnings- uppkopplin:g i telefonnat av godtycklig utformning med sarskiljande numrering av lokalstationerna eller lokalnaten. Inventors: M Novotny, JH Rott and J Pekarek Priority given from 19 May 1959 (Czechoslovakia) The present invention relates to a method for transmitting a selected number by means of registers, especially in connection with a dial-up telephone. with distinguishing numbering of the local stations or local notes.

I telefonnat, som anvanda flera genomgangsstationer for att astadkomma en for- hindning fran en avgangsstation till en be- stammelsestation, overfores det valda numret, som bestar av ett riktnummer, som kan- netecknar den anropade lokalstationen eller del anropade lokalnatet, och ett abonnentnummer, pa olika salt. In telephone nights, which use several transit stations to provide an obstacle from a departure station to a destination station, the selected number, which consists of an area code, which identifies the called local station or part of the called local network, is transmitted and a subscriber number, on different salts.

Ett kant satt bestar dart att registret i avgangsstationen (avgangsregistret) mottager hela abonnentnumret, kopplar upp en for- bindningsyag till en motsvarande genomgangsstation och darefter avger hela det val- da numret till registret i genomgangsstatio- nen. Registret i genomgangsstationen arbetar pa samma satt som registret i avgangsstatio- nen och overfor darfor hela det valda numret till registret i den efterfoljande genomgangsstationen. Detta farlopp upprepas, tills det valda numret &efforts till bestammelselokal- stationen eller -lokalnatet, dar forbindningen till den anropade abonnenten astadkommes. An edge set consists in dart that the register in the departure station (departure register) receives the entire subscriber number, connects a connection yag to a corresponding transit station and then submits the entire selected number to the register in the transit station. The register in the transit station operates in the same way as the register in the departure station and therefore the entire selected number to the register in the subsequent transit station. This process is repeated until the selected number & efforts to the destination local station or locality, where the connection to the called subscriber is established.

Detta forfarande for Overforing av ett valt nummer visas schematiskt pa fig. 1. I denna figur betecknar U en abonnentapparat, OR avgangsregistret, TR1 genomgangsregistret i den fOrsta genomgangsstationen, TR2 genomgangsregistret i den andra genomgangsstationen, M bestamrnelselokalstationen, x, y, z, siffror i ett tresiffrigt riktnummer och a, b, c, d, e siffror i ett abonnentnummer De med de angivna bokstaverna betecknade pilarna angiva varifran och varthan de motsvarande siffrorna overfOras. This procedure for transmitting a selected number is shown schematically in Fig. 1. In this figure, U denotes a subscriber apparatus, OR the departure register, TR1 the passage register in the first passage station, TR2 the passage register in the second passage station, M the control room station, x, y, z, numbers in a three-digit area code and a, b, c, d, e digits in a subscriber number The arrows denoted by the letters indicated indicate where and from which the corresponding digits are transferred.

Sasom framgar av beskrivningen och av fig. 1, maste registret i vane f5rmedlingssta tion, som deltar i forbindningsuppkopplingen, mottaga och avsanda hela det valda numret, varfor alla register bli stora och komplicerade. As can be seen from the description and from Fig. 1, the register in the usual switching station, which participates in the connection connection, must receive and send the entire selected number, for which reason all registers become large and complicated.

Vid de hittills kanda losningarna elimineras denna nackdel darigenom, att registren i genomgangsstationerna vid forbindningsuppkopplingen endast mottaga och atergiya riktnumret. Darvid anyandas tvd salt for overforingen av ett valt nummer. In the hitherto known solutions, this disadvantage is eliminated in that the registers in the transit stations at the connection connection only receive and atergiya the area code. Darvid anyandas tvd salt for the transmission of a selected number.

Vid det fOrsta kanda sattet, vid vilket genomgangsregistren endast mottaga riktnumret, upplagras hela det slagna numret i avgangsregistret, som uppkopplar en forbindningsvag till den forsta genomgangsstationen och avger riktnumret till det forsta genomgangsregistret. Det forsta genomgangsregistret astadkommer sedan en forbindning till den efterfoljande genomgangsstationen och utloses. Darefter upprepas utsandningen av det i avgangsregistret upplagrade riktnumret till den andra genomgangsstationen. Detta fOrlopp, vid vilket avgangsregistret avger riktnumret till den aktuella, efterfoljande genomgangsstationen, upprepas, tills forbindningen till den anropade lokalstationen alstrats. Darefter avger avgangsregistret den anropade abonnentens nummer. Delta forfarande for overforing ay ett valt nummer visas schematiskt pa fig. 2, narmare bestanat for tre fall: fall 2a gaiter fiir ett ensiffrigt riktnummer, fall 2b fOr ett tvasiffrigt riktnummer och 2c for ett tresiffrigt riktnummer. At the first station, in which the transit registers only receive the area code, the entire dialed number is stored in the departure register, which connects a connecting carriage to the first transit station and outputs the area code to the first transit register. The first transit register then establishes a connection to the subsequent transit station and is triggered. Then the transmission of the area code stored in the departure register to the second transit station is repeated. This process, in which the departure register gives the area code to the current, following transit station, is repeated until the connection to the called local station has been generated. Then the departure register gives the number of the called subscriber. This procedure for transmitting a selected number is shown schematically in Fig. 2, more specifically for three cases: case 2a for a one-digit area code, case 2b for a two-digit area code and 2c for a three-digit area code.

Det andra sattet for overforing av ett valt nummer, vid vilket genomgangsregistren likaledes endast mottaga riktnumret, bestar dari, att registret i avgangsstationen forst endast mottager riktnumret och avger detsamma efter alstrandet av en forbindning till den forsta genomgangsstationen. Darefter utloses registret. Det forsta genomgangsregistret uppkopplar en forbindningsvag till det andra genomgangsregistret och utloses darefter. Denna 2— — stafettoverforing av riktnumret sker, tills anropet anlander till bestammelselokalstationen eller -lokalnatet, frail vilket den anropande abonnenten erhaller en svarston och kan borja sla det onskade abonnentnumret. Sifferimpulserna tiverfaras sedan till den anropade lokalstationen utan medverkan av register. Detta forfarande visas schematiskt pa fig. 3a for ett ensiffrigt riktnummer, pa fig. 3b for ett tvasiffrigt riktnummer och pa fig. 3e ftir ett tresiffrigt riktnummer. The second method of transmitting a selected number, in which the transit registers likewise only receive the area code, consists in that the register in the departure station first only receives the area code and delivers the same after generating a connection to the first transit station. The register is then triggered. The first throughput register connects a connection path to the second throughput register and is then triggered. This 2 - - relay transfer of the area code takes place until the call arrives at the destination local station or location, from which the calling subscriber receives a response tone and can start dialing the desired subscriber number. The number pulses are then transmitted to the called local station without the participation of registers. This method is shown schematically in Fig. 3a for a one-digit area code, in Fig. 3b for a two-digit area code and in Fig. 3e for a three-digit area code.

Det är givet, att vid det sista forfarandet for overforing av ett valt Rummer alla telefonistationerna kunna vara forsedda med de enklaste registren, eftersom registren endast mottaga och utsanda riktnumren. Med denna for-del foljer dock den nackdelen, att den anropande abonnenten efter slagningen av riktnumret maste vanta pa en akustisk signal, innan han kan fortsatta. Om det är nadvandigt, att den anropande abonnenten skall kunna valja hela det anskade numret utan avbrott, maste avgangsstationen vara forsedd med ett register, som upplagrar hela det valda numret men endast avger riktnumren till genomgangsregistren. Under dessa forhallanden utsanda genomgangsregistren riktnurnren stafettvis, &Isom beskrivits, och forst efter alstringen av en forbindning till bestammelselokalstationen eller lokalnatet avges abonnentnumret fran avgangsregistret. De bada varianterna, vid vilka endast riktnumret oversandes till bestammelselokalstationen vid forbindningsuppkopplingen, aro ungefar likvardiga med avseende pa registrens uppbyggnad, dvs. registret 1 avgangsstationen maste upplagra hela det valda numret, medan registren i genomgangsstationerna endast mottaga riktnumren. Detta forfarande kan lattast anvandas i fjarrtelefoninat, i vilka alla riktnumren ha samma antal siffror, emedan genomgangsregistret efter antalet mottagna siffror kanner, att det erhdllit tillracklig information och kan utvardena de mottagna siffrorna. It is a given that in the last procedure for transmitting a selected Room, all the telephone exchanges may be provided with the simplest registers, since the registers only receive and send the area codes. With this advantage, however, comes the disadvantage that the calling subscriber, after dialing the area code, must wait for an acoustic signal before he can continue. If it is necessary for the calling subscriber to be able to dial the entire requested number without interruption, the departure station must be provided with a register which stores the entire selected number but only delivers the area codes to the transit registers. During these conditions, the transit registers send out the direction numbers relaywise, & As described, and only after the generation of a connection to the destination local station or local network is the subscriber number issued from the departure register. The two variants, in which only the area code is transmitted to the destination local station at the connection connection, are approximately equivalent with regard to the structure of the registers, ie. the register in the departure station must store the entire selected number, while the registers in the transit stations only receive the area codes. This method can most easily be used in remote telephony networks, in which all area codes have the same number of digits, since the transit register, according to the number of digits received, can ensure that it has obtained sufficient information and can evaluate the digits received.

Det finns dock telefoninat, i vilka riktnumren, som kanneteckna de enskilda lokalstationerna, innehdlla olika antal siffror. En sadan numrering anvandes foretradesvis, om nagra stationer i natet aro stora och andra sma. Under sa.dana omst5.ndigheter kan riktnumren for de stora stationerna vara exempelvis ensiffriga eller tvasiffriga, medan riktnumren for de mindre stationerna aro tresiffriga. However, there are telephone networks in which the area codes, which can indicate the individual local stations, contain different numbers of numbers. Such a numbering is preferably used if some stations in the network are large and others small. Under such circumstances, the area codes for the large stations can be, for example, single-digit or double-digit, while the area codes for the smaller stations are three-digit.

I det telefonindt, som visas schematiskt pa fig. 5, (varvid de ofyllda cirklarna beteckna genomgangsstationer, medan de fyllda eirklarna beteckna lokalstationer eller lokalnat) kan exempelvis en abonnent tillhorande stationen nummer 537 anropa en abonnent i en godtycklig station. Genomgdngsregistret vid formedlingspunkten C maste dá bestamma avgangsriktningen redan efter mottagning av den forsta siffran, om siffran 2 installes. Vid riktnummer, som borja med siffran 4, kan genomgangsregistret i fiirmedlingspunkten C bestamma riktningen efter den ftirsta siffran med undantag for numret 425. Om riktnumret barjar med siffran 3 eller 5, kan registret faststalla riktningen f8rst efter mottagning av tvd_ (talen 37, 52, 54 och 55) eller tre siffror. In the telephone line shown schematically in Fig. 5, (where the filled circles denote transit stations, while the filled circles denote local stations or local area), for example, a subscriber belonging to station number 537 may call a subscriber in an arbitrary station. The transit register at the transfer point C must then determine the direction of departure already after receipt of the first digit, if the digit 2 is installed. For area codes beginning with the number 4, the transit register in the transmission point C can determine the direction after the first digit with the exception of the number 425. If the area code starts with the number 3 or 5, the register can determine the direction only after receiving tvd_ (numbers 37, 52, 54 and 55) or three digits.

Vid detta forfarande maste registret analysera det mottagna riktnumret, dvs. efter mottagning av varje siffra maste registret be-stamina, om antalet siffror racker till eller inte for att uppstika den motsvarande forbindningsvagen. Till MA harav blir registret alltfor stort. I moderna system anyandas darfor de s. k. centralomraknarna. Centralomraknaren anslutes till registret, sâ snarl hela riktnumret upplagrats i detsamma, och i overensstammelse med detta nummer bestammer den riktningen resp. overforingsfOrhallandena for den vidare forbindelseuppkopplingen. Darefter frankopplas omranaren frail registret. Genom denna anordning koncentreras de komplicerade stromkretsarna for analysering och utvardering av riktnumren i centralomrdknaren, varfor registren icke innehalla nagra shdana stromkretsar och darigenom kunna garas betydligt enklare. Om riktnumren innehalla olika antal sifferlagen, mdste antingen registret sjalv utfora analyseringen eller anslutas till centralomraknaren efter upplagringen av varje siffra i riktnumret, varfor centralomrdknaren i detta fall blir upptagen praktiskt taget under hela tiden for slagning av riktnumret. For att klara denna belastning skulle ett stone antal centralomraknare erfordras. In this procedure, the register must analyze the received area code, ie. after receiving each digit, the register must determine whether or not the number of digits is sufficient to indicate the corresponding connection path. For MA, the register becomes too large. In modern systems anyandas therefore the so-called central converters. The central converter is connected to the register, so that the entire area code is stored in the same, and in accordance with this number it determines the direction resp. the transmission conditions for the further connection connection. Then the remover is disconnected from the register. This device concentrates the complicated circuits for analyzing and evaluating the area codes in the central converter, so that the registers do not contain any such circuits and can thus be made much simpler. If the area codes contain different numbers of digits, the register itself must perform the analysis itself or be connected to the central converter after storing each digit in the area code, so in this case the central area converter is occupied practically all the time for dialing the area code. To cope with this load, a stone number of central converters would be required.

De namnda nackdelarna elimineras genom sattet enligt uppfinningen for overforing av ett valt nummer, vilket i huvudsak kannetecknas darav, att avgangsregistret upplagrar hela det valda nnmret och till genomgangsregistret overf5r endast en siffergrupp uppvisande ett antal siffror, som ãr lika med antalet siffror i det langsta forekommande riktnumret, och att darvid antalet ovriga sifferlagen vid kortare riktnummer utfyllas go-nom de forsta siffrorna i abonnentnumret, varefter den pa detta satt sammansatta siffergruppen averfores stafettvis fran ett register till ett annat pa i och for sig kant salt tram till det sista genomgangsregistret, som endast overfor de siffror i denna siffergrupp, som tillhora det valda abonnentnumret, till bestammelselokalstationen eller -lokalnatet, medan de ovriga siffrorna i abonnentnumret avges direkt fran avgangsregistret till bestdmmelselokalstationen eller -lokalnatet forst efter alstrandet av den onskade forbindelsen fram till denna eller detta. The mentioned disadvantages are eliminated by the method according to the invention for transmitting a selected number, which is mainly characterized by the fact that the departure register stores the entire selected number and to the transit register only a number group having a number of digits is equal to the number of digits in the longest occurrence. the area code, and that the number of other digits in the case of shorter area codes is filled in by the first digits of the subscriber number, after which the group of numbers composed on it is relayed from one register to another on a per se edge tram to the last passage register, which only to the digits in this group of digits, which belong to the selected subscriber number, to the destination local station or locality, while the other digits in the subscriber number are issued directly from the departure register to the destination locality or locale only after the generation of the desired connection up to this or that.

Detta betyder, att genomgangsregistret alltid mottager samma antal siffror oberoende av antalet siffror i bestdmmelsestationens riktnummer och darefter anropar centralomrdknaren. Genomgdngsregistret beh8ver icke in- — — nehalla nagra stromkretsar for utvardering av det mottagna numret. Siffergruppen OverfOres till alla de i forbindningen deltagande genomgangsregistren. Det sista genomgangsregistret i forbindningen erhaller Iran sin egen stationscentralomraknare siffror, som utgora en del av abonnentnumret, och overfor dessa siffror till bestammelselokalstationen. De Ovriga siffrorna i abonnentnumret, som icke f5refinnas i den av genomgangsregistren OverfOrda siffergruppen, avges av avgangsregistret och overforas direkt frau_ a-vgangsstationen: till bestammelsestationen. This means that the transit register always receives the same number of digits regardless of the number of digits in the destination number of the destination station and then calls the central converter. The review register does not need to contain any circuits for evaluating the received number. The number group OverfOres to all the review registers participating in the connection. The last throughput register in the connection, Iran receives its own station central converter numbers, which form part of the subscriber number, and opposite these numbers to the destination local station. The Other digits in the subscriber number, which are not found in the group of numbers transferred by the transit registers, are given by the departure register and transferred directly from the departure station to the destination station.

Sattet for overforing av ett valt nummer enligt uppfinningen visas schematiskt pa fig. 4, som Ater visar Ire fall. Fallet 4a galler for ett ensiffrigt riktnummer, fallet 4b for ett tvasiffrigt riktnummer och fallet 40 for ett tresiffrigt riktnummer. Sasom framgar av figuren, kompletteras det ensiffriga eller tvasiffriga riktnumret med tvâ siffror resp. en siffra av abonnentnumret till en tresiffrig siffergrupp under forutsattning, att (let langsta riktnumret liar ire siffror. The method for transmitting a selected number according to the invention is shown schematically in Fig. 4, which again shows a case. Case 4a applies to a one-digit area code, case 4b for a two-digit area code and case 40 for a three-digit area code. As can be seen from the figure, the single-digit or double-digit area code is supplemented with two digits resp. a digit of the subscriber number of a three-digit group of digits, provided that the longest area code is in digits.

SjaIva kopplingen av registren visas joke har, eftersom den enligt uppfinningen arbetande kopplingsanordningen kan astadkommas genom olika model och med hansyn till teknikens nuvarande standpunkt joke here-der fackmannen nagra svarigheter. The actual coupling of the registers is shown to have a joke, since the coupling device operating according to the invention can be achieved by different models and with regard to the current state of the art joke here, the person skilled in the art has some responsibilities.
