Description
Signaleringssystem. Signaling system.
Den foreliggende oppfinnelse angår et signaleringssystem for en ledningsgruppe som er tilkoblet sentralt anordnet styreutstyr i telekommunikasjonssystemer, særlig telefonisystemer. The present invention relates to a signaling system for a wiring group which is connected to centrally arranged control equipment in telecommunications systems, in particular telephony systems.
Når en forbindelse skal etableres, ut-veksler de forskjellige utstyrsenheter i sen-tralen mange informasjoner. Det er derfor et ubetinget krav at overføringen foregår så sikkert som mulig. Dette krav tilfreds-stilles lett dersom informasjonene repre-senteres i en kontrollerbar kode, men dette forutsetter at informasjonene tilføres ved definerte tidspunkter. When a connection is to be established, the various equipment units in the central exchange a lot of information. It is therefore an absolute requirement that the transfer takes place as securely as possible. This requirement is easily satisfied if the information is represented in a controllable code, but this requires that the information is supplied at defined times.
Slike koder kan lett kontrolleres av elektronisk kontrollutstyr. Ved signaler som ikke tilføres regelmessig og som må sendes over kombinerte signaleringsgrupper, vil ikke kjente overføringsmetoder være til-strekkelige. Kodekontroll vil ofte være umulig dersom informasjonen foreligger i binær form. Such codes can be easily checked by electronic control equipment. In the case of signals which are not supplied regularly and which must be sent over combined signaling groups, known transmission methods will not be sufficient. Code control will often be impossible if the information is in binary form.
Slike koder benyttes vanligvis hvor flersifret nummerskiveinf ormas jon skal sendes i parallell over en flertråds signal-eringsgruppe. Overføringen av informasjon mellom et register og en markør er eksem-pelvis beskrevet i forbindelse med en tele-fonsentral. Registeret er bare forbundet med markøren i et kort tidsrom ved hjelp av et koblingsnettverk. Such codes are usually used where multi-digit dial information is to be sent in parallel over a multi-wire signaling group. The transfer of information between a register and a marker is described, for example, in connection with a telephone exchange. The register is only connected to the marker for a short period of time by means of a link network.
Formålet med den foreliggende oppfinnelse er å tilveiebringe et signaleringssystem for midlertidig sammenkobling av ledningsgrupper i sentralstyreutstyr omfattende senderutstyr og mottagerutstyr i et sambandssystem, og særlig i en telefon-sentral. Signaleringssystemet muliggjør en sikker signaloverføring, og gjennomkoblingen og den riktige påvirkning av trådene, så vel som mottakerens klartilstand, kontrolleres automatisk. The purpose of the present invention is to provide a signaling system for the temporary interconnection of wiring groups in central control equipment comprising transmitter equipment and receiver equipment in a communication system, and in particular in a telephone exchange. The signaling system enables a safe signal transmission, and the pass-through and the correct influence of the wires, as well as the ready state of the receiver, are checked automatically.
Det vesentligste særtrekk ved oppfinnelsen er at på sendersiden tilføres et testpotensial til alle tråder i ledningsgruppen, og at senderutstyret bare innkobles når det over et testutstyr og over alle gjennom - koblede tråder tilføres et motvirkende potensial med bestemt størrelse til mottager - utstyret. Derved sikres at signalering bare påbegynnes når: The most important distinguishing feature of the invention is that on the transmitter side a test potential is applied to all wires in the wiring group, and that the transmitter equipment is only switched on when a countervailing potential of a certain size is applied to the receiver equipment over a test equipment and over all through-connected wires. This ensures that signaling only starts when:
1. Alle signal tråder er gjennomkoblet. 1. All signal wires are connected through.
2. En mottager er koblet til alle signal - tråder på mottagersiden og 3. Signal trådene ikke er påtrykket noe annet potensial eller har utillatelige avledninger. 2. A receiver is connected to all signal wires on the receiver side and 3. The signal wires are not impressed with any other potential or have inadmissible leads.
En fordelaktig utførelse av signaleringssystemet ifølge oppfinnelsen er slik at det for hver overføringsretning benyttes en An advantageous embodiment of the signaling system according to the invention is such that one is used for each direction of transmission
individuell ledningsgruppe og at det motvirkende signal, som tilføres en tråd i den individual wire group and that the counteracting signal, which is supplied to a wire in it
ene overføringsretning, er avhengig av gjennomkoblingen av alle tråder i den andre overføringsretning. På denne måte blir begge signalgrupper kontrollert før sendersiden begynner å sende informasjonen. En slik kontroll foretas idet et utstyr begynner å sende informasjon. Ofte forekommer det også at det i to sammenkoblede one transmission direction, is dependent on the interconnection of all wires in the other transmission direction. In this way, both signal groups are checked before the sending side starts sending the information. Such a check is carried out when a piece of equipment starts sending information. Often it also happens that in two connected
utstyr forekommer en slags toveisrettet in-formasjonsoverføring. Overføringen begynner såsnart informasjonen tilføres en av endene. For signalgrupper som er koblet på ønsket måte, muliggjør signaleringssystemet ifølge oppfinnelsen, at når test-potensialet tilføres fra den sendende stasjon til den utgående ledningsgruppe, vil samtidig det motvirkende potensial frakobles mottagerutstyret ved den avslut-tende ledningsgruppe. Når det motvirkende potensial kobles av i mottagerutstyret, sikres det at denne ende ikke kan begynne å signalere. equipment, a kind of two-way information transfer occurs. The transfer begins as soon as the information is supplied to one of the ends. For signal groups that are connected in the desired way, the signaling system according to the invention makes it possible that when the test potential is supplied from the transmitting station to the outgoing line group, at the same time the counteracting potential will be disconnected from the receiver equipment at the terminating line group. When the counteracting potential is disconnected in the receiving equipment, it is ensured that this end cannot start signaling.
En annen utførelse av signaleringssystemet ifølge oppfinnelsen er slik at ved påvirkning av både sender- og mottager-sidens styreutstyr som er sammenkoblet for å utveksle signaler, blir tidsmålekretser innkoblet, idet disse kretser bevirker utsendelse av et feilsignal, dersom ikke en vellykket forbindelse og heller ikke senderutstyrets klartilstand er registrert i løpet av den forutbestemte tid. Another embodiment of the signaling system according to the invention is such that when the control equipment on both the transmitter and the receiver side, which are interconnected to exchange signals, are affected, timing circuits are switched on, these circuits causing the sending of an error signal, if not a successful connection and also not the transmitter equipment's ready state is registered during the predetermined time.
Feilaktige forbindelser kan hurtig un-dersøkes slik at unødvendig påvirkning av sentralutstyret unngås. Ved hjelp av eg-net registreringsutstyr kan den feilaktige forbindelse registreres og sentralstyreut-styret utløses igjen. Faulty connections can be quickly examined so that unnecessary influence on the central equipment is avoided. With the help of proprietary recording equipment, the incorrect connection can be registered and the central control device triggered again.
En fordelaktig testanordning kan ut-føres slik at testpotensialet tilføres alle tråder over høyohmige motstander, og at mottagerutstyret ikke påvirkes av dette. Tilførselsmotstandene for kontrollpoten-sialet danner sammen med det motvirkende potensial i mottageren en spenningsdeler. Alle spenningsdelere styrer igjen en og-port som bare reagerer når alle tilkoblings-punkter på spenningsdelerne har samme potensial. An advantageous test device can be designed so that the test potential is applied to all wires via high-resistance resistors, and that the receiver equipment is not affected by this. The supply resistances for the control potential together with the counteracting potential in the receiver form a voltage divider. All voltage dividers in turn control an AND gate which only reacts when all connection points on the voltage dividers have the same potential.
To utførelser av signaleringssystemet ifølge den foreliggende oppfinnelse vil i det følgende bli detaljert beskrevet under hen-visning til tegningene, hvor: Fig. 1 viser utstyr for en-veisrettet sig-naloverføring, og Fig. 2 viser utstyr for to-veisrettet sig-naloverføring hvor den ene stasjon har prioritet. Two embodiments of the signaling system according to the present invention will in the following be described in detail with reference to the drawings, where: Fig. 1 shows equipment for one-way signal transmission, and Fig. 2 shows equipment for two-way signal transmission where one station has priority.
I fig. 1 er et punkt A koblet til B over et koblingsnettverk KF, når trådene 1—3 er gjennomkoblet over kontaktene d. A representerer sendersiden og B representerer mottagersiden. Ved A tilføres testpotensialet +U2 hver tråd. Tilførselsmotstan-dene Ria, R2a—Ria', R2a'—R2a", er høy-ohmige og valgt slik at mottagerne ved B ikke reagerer. En motstand Rb i transistor-styrekretsen Tb er koblet til signaltråden 1. Sålenge tråden 1 ikke er gjennomkoblet, vil transistoren Tb lede. Mottagerreleene Xb og Yb er koblet til trådene 2 og 3, hvis releer ikke reagerer på grunn av de høy-ohmige tilførselsmotstander ved A. Alle tre mottagere ved B er koblet til et motvirkende potensial —Ul. Mellom motstandene Ria og R2a, Ria' såvel som mellom Ria" og R2a", er og-kretsen innkoblet, idet denne krets omfatter diodene Da, Da', Da", motstanden R2a og transistoren Tab. Alle disse dioder Da, Da', Da" leder sålenge trådene 1—3 ikke er gjennomkoblet. In fig. 1 is a point A connected to B via a connection network KF, when the wires 1-3 are connected through the contacts d. A represents the transmitter side and B represents the receiver side. At A, the test potential +U2 is applied to each wire. The supply resistors Ria, R2a—Ria', R2a'—R2a", are high-ohmic and chosen so that the receivers at B do not react. A resistor Rb in the transistor control circuit Tb is connected to signal wire 1. As long as wire 1 is not connected through , the transistor Tb will conduct. The receiver relays Xb and Yb are connected to wires 2 and 3, whose relays do not respond due to the high-ohmic supply resistors at A. All three receivers at B are connected to an opposing potential —Ul. Between the resistors Ria and R2a, Ria' as well as between Ria" and R2a", the and circuit is connected, this circuit comprising the diodes Da, Da', Da", the resistor R2a and the transistor Tab. All these diodes Da, Da', Da" conduct as long as wires 1-3 are not connected through.
Transistoren Tab mottar sperrespen-ning og forblir ikke-ledende.- Såsnart en tråd er gjennomkoblet og overfører det motvirkende potensial —Ul, vil dioden som er koblet til tråden bli ikke-ledende. Bare når alle tråder er gjennomkoblet og over-fører det motvirkende potensial —Ul med definert størrelse, vil alle dioder i og-kretsen bli ikke-ledende og utløse styre-potensialet —Ul over motstanden R3a, slik at transistor Tab leder. Ved riktig dimen-sjonering av motstandene Ria, R2a og mot-tagersidens motstand, oppnås en enkel testanordning for tråden overfor uvedkom-mende spenninger eller avledninger. Den tilhørende diode gjøres ikke ikke-ledende i de tilfeller hvor det opptrer feil, slik at transistor Tab forblir sperret. Når transistor Tab leder, dvs. når alle tråder 1—3 er klar for signaloverføring, påvirkes rele CG og utløser over sin kontant cg2, sig-naloverføringskontaktene sal, sa2 og sa3. Disse kontakter tilfører jordpotensial til trådene i avhengighet av den informasjon som skal sendes. Deretter reagerer mottagerne på mottagersiden B. Jordpotensia-let gjør transistoren Tb ikke-ledende, da styre-spenningen —Ul avledes i styrekret-sen. Når A påvirkes, blir en kontakt c til-hørende et påvirkende rele( ikke vist) sluttet. Etter at releet CG er påvirket, vil hol-dekretsen for releet bli sluttet over kon-takten egl, slik at tilstanden for testtran-sistoren Tab ikke har noen betydning mens signalene sendes. The transistor Tab receives blocking voltage and remains non-conductive.- As soon as a wire is connected through and transfers the counteracting potential —Ul, the diode connected to the wire will become non-conductive. Only when all wires are connected through and transmit the counteracting potential —Ul of defined size, will all diodes in the and circuit become non-conductive and trigger the control potential —Ul across the resistor R3a, so that transistor Tab conducts. By correctly dimensioning the resistances Ria, R2a and the resistance on the receiver side, a simple test device for the wire against extraneous voltages or leads is achieved. The associated diode is not made non-conductive in the cases where errors occur, so that transistor Tab remains blocked. When transistor Tab conducts, i.e. when all wires 1—3 are ready for signal transmission, relay CG is affected and triggers via its current cg2, the signal transmission contacts sal, sa2 and sa3. These contacts add ground potential to the wires depending on the information to be sent. The receivers then react on the receiver side B. The ground potential makes the transistor Tb non-conductive, as the control voltage —Ul is diverted in the control circuit. When A is affected, a contact c belonging to an influencing relay (not shown) is closed. After the relay CG is affected, the holding circuit for the relay will be closed across the contact egl, so that the state of the test transistor Tab has no significance while the signals are being sent.
Fig. 2 viser det samme testarrangement for begge ledningsgrupper Bab og Bba. I A er det anbragt en testtransistor Tab som styres av og-porten, som består av diodene Da, Da', Da", og motstanden R3a. I B er det anbragt en testtransistor Tba som styres av en og-krets, som består av diodene Db, Db', Db" og motstanden R3b. Fig. 2 shows the same test arrangement for both wire groups Bab and Bba. In A, a test transistor Tab is placed which is controlled by the AND gate, which consists of the diodes Da, Da', Da", and the resistor R3a. In B, there is a test transistor Tba which is controlled by an AND circuit, which consists of the diodes Db , Db', Db" and the resistor R3b.
Begge transistorene Tab og Tba til-fører i sine ledende tilstander jordpotensial til kontaktene sal, sa2, og sb2, sbl, sb3. Kontaktene cal og ca2 i et påvirkende rele (ikke vist) sluttes i A når kretsen påvirkes. En tidsmålekrets Za startes over kontak-ten ca2. Når transistor Tza forblir ledende, Both transistors Tab and Tba, in their conducting states, supply ground potential to the contacts sal, sa2, and sb2, sbl, sb3. The contacts cal and ca2 in an influencing relay (not shown) are closed in A when the circuit is influenced. A time measuring circuit Za is started over the contact ca2. When transistor Tza remains conducting,
dvs. når transistor Tab ikke signalerer at i.e. when transistor Tab does not signal that
«trådene befinner seg i riktig tilstand», ut-sendes et feilsignal fra tidsmålekretsen Za. "the threads are in the correct state", an error signal is emitted from the time measuring circuit Za.
Tilsvarende tilstander oppstår ved B. Kontaktene cbl og cb2 sluttes under påvirk-ningsprosessen. Tidsmålekretsen Zb til-kobles. I løpet av nevnte tidsperiode blir Corresponding conditions occur at B. The contacts cbl and cb2 are closed during the influencing process. The time measurement circuit Zb is connected. During the said time period,
transistor Tba ledende og transistor Tzb transistor Tba conducting and transistor Tzb
ikke-ledende, dersom alle tråder i ledningsgruppen Bba befinner seg i riktig tilstand. non-conductive, if all wires in the wire group Bba are in the correct condition.
Som allerede nevnt ovenfor blir transistor As already mentioned above becomes transistor
Tba ledende når alle dioder Db, Db', Db" Tba conducting when all diodes Db, Db', Db"
sperres over det motvirkende potensial is blocked over the counteracting potential
—Ul i stasjonen A. Ledningsgruppen Bab —Ul in station A. Ledningsgruppen Bab
har nå en individuell styrelinje L. Det motvirkende potensial —Ul holdes borte fra now has an individual control line L. The counteracting potential —Ul is kept away from
linjen L i stasjonen B med hjelp av den line L in station B using it
ledende transistor Tzb, inntil transistoren conducting transistor Tzb, next to the transistor
Tba blir ledende, dvs. at ledningsgruppen Tba becomes the leader, i.e. that the leadership group
Bba befinner seg i riktig tilstand. Bare da Bba is in correct condition. Only then
kan transistor Tab lede, da dioden Da også can transistor Tab conduct, then diode Da too
sperres over det motvirkende potensial is blocked over the counteracting potential
—Ul som tilføres styretråden L. Det er nu —Ul which is supplied to the guide thread L. That's it now
nødvendig å sikre at de ledende transisto-rer Tab og Tba forblir ledende under sig-nalutvekslingen. Dette kan oppnås på enkel necessary to ensure that the conducting transistors Tab and Tba remain conducting during the signal exchange. This can be achieved in simple

Det skal anmerkes at antall signaltrå-der ikke er begrenset, som antydet, av transistorene Ta og Tb og/eller av releene Xa, It should be noted that the number of signal wires is not limited, as indicated, by the transistors Ta and Tb and/or by the relays Xa,
