Description
Fig. 3 zeigt die Freischaltung des Identifizierers bei Besetztsein der durch eine anrufende Sprechstelle belegbaren Zwischenleitungen.Fig. 3 shows the activation of the identifier when the intercom can be occupied by a calling station.
In der F i g. 1 ist die Gruppierung der Koppelpunkte und der die Koppelpunkte verbindenden Zwischenleitungen gezeigt. Die Sprechstelle iV40 wird nach Abheben des Hörers über den Koppelpunkt 40/1 der Einerkoppelstufe EK 4 mit der Zehnerkoppelstufe ZX1 über die Zwischenleitung 1/4 verbunden. Der Koppelpunkt 4/1 der Koppelstufe ZKl wird über die Zwischenleitung 1/1 mit der Mischkoppelstufe' MKl und über den Koppelpunkt 1/1 dieser Mischkoppelstufe mit der — vor der Markierung im Wegesücher als frei gekennzeichneten — Übertragung HU1 verbunden. Dieser Übersicht kann entnommen werden, daß alle durch die Sprechstelle N 40 belegbaren Zwischenleitungen im Ausführungsbeispiel über die Koppelpunktreihen 4 der Zehnerkoppelstufen ZK1 bis ZK 8 führen.In FIG. 1 shows the grouping of the crosspoints and the intermediate lines connecting the crosspoints. After lifting the handset, the intercom station iV40 is connected via the coupling point 40/1 of the single coupling stage EK 4 to the ten coupling stage ZX1 via the intermediate line 1/4. The coupling point 4/1 of the coupling stage ZKl is connected via the intermediate line 1/1 to the mixed coupling stage 'MKl and via the coupling point 1/1 of this mixed coupling stage with the transmission HU 1 - which is marked as free before the marking in the path search. It can be seen from this overview that all intermediate lines that can be occupied by the telephone station N 40 in the exemplary embodiment lead via the crosspoint rows 4 of the decoupling stages ZK 1 to ZK 8.
Der F i g. 2 kann entnommen werden, daß in den Haltestromkreisen für die Koppelrelais der Zehnerund Mischkoppelstufen »Zwischenleitung-besetzt«- Kennzeichenrelais, z. B. BZ1/1 und BM1/1 vorgesehen sind. Die Kontakte dieser Relais steuern Relais P1 bis P 8, welche die belegbaren Zwischenleitungen kennzeichnen. Eine Zwischenleitung und damit auch ein F-Relais ist jeweils einer bestimmten Koppelstufe des Zehnerkopplers zugeordnet. Der Zehnerkoppelstufe ZKl ist das Relais Pl zugeordnet. Die Einschaltung dieses Relais erfolgt in Abhängigkeit von der Zehnerkennzeichnung, z.B. Kontakt 10sz4 betätigt, der im Identifizierer TAS gekennzeichneten Sprechstelle und der Kennzeichnung der freien Übertragung, z. B. durch den Kontakt 11hm 1. Ist keine Zwischenleitung für die durch den Kontakt 10 sz 4 gekennzeichnete Sprechstelle belegbar, so sind sowohl alle Kontakte bm 1/1 bis bm 1/3 ... fern 8/1 bis bm 8/3 (die den Mischkoppelstufen zugeordnet sind, die an den Übertragungen an der zur anrufenden Sprechstelle gekehrten Seite liegen) als auch alle Kontakte bz 1/1 bis bz 8/1 (die den von der anrufenden Sprechstelle belegbaren ersten Koppelpunktreihen der Zehnerkoppelstufen ZKl bis ZK 8 zugeordnet sind) betätigt. Für keines der Relais P 1 bis P 8, PB werden dann durch die Kontakte 10sz4 und 11hm 1 Einschaltstromkreise geschlossen.The F i g. 2 it can be seen that in the holding circuits for the coupling relays of the tens and mixed coupling stages "intermediate line occupied" - indicator relays, e.g. B. BZ 1/1 and BM 1/1 are provided. The contacts of these relays control relays P1 to P 8, which mark the assignable intermediate lines. An intermediate line and thus also an F-relay is assigned to a specific coupling stage of the decoupler. The relay Pl is assigned to the ten coupling stage ZKl. This relay is switched on depending on the tens identification, eg contact 10 sz 4 actuated, the call station marked in the identifier TAS and the identification of free transmission, e.g. B. through contact 11hm 1. If no intermediate line can be used for the call station marked by contact 10 sz 4, all contacts bm 1/1 to bm 1/3 ... remote 8/1 to bm 8/3 ( which are assigned to the mixed coupling stages that are on the transmissions on the side facing the calling station) as well as all contacts bz 1/1 to bz 8/1 (which are allocated to the first crosspoint rows of the ten coupling stages ZKl to ZK 8 that can be occupied by the calling station ) operated. For none of the relays P 1 to P 8, PB 1 switch-on circuits are then closed by the contacts 10sz4 and 11hm.
Durch Abheben des Hörers einer Sprechstelle, beispielsweise iV40 in Fig. 3, wird in bekannter Weise das Relais R 2 eingeschaltet und über den Kontakt Ir2 ein Anruf anreiz zum Identifizierer TAS gegeben. In diesem Identifizierer werden die die anrufende Sprechstelle kennzeichnenden Relais SE 2, By lifting the receiver of a call station, for example IV40 in FIG. 3, the relay R 2 is switched on in a known manner and a call stimulus is given to the identifier TAS via the contact Ir2 . In this identifier the relays SE 2,
ίο SZ 4 und SHl dann wirksam, wenn kein anderer Anruf anreiz in diesem Identifizierer wirksam ist, d. h. der Kontakt 2gse in der Ruhelage ist. Über den Kontakt lOsz 4 des bei der Identifizierung der anrufenden Sprechstelle eingeschalteten Relais SZ 4 kann, wie vorstehend ausgeführt, kein Stromkreis für eines der Relais P1 bis P 8 zustande kommen (vgl. Fig. 2). Über die Kontakte 12ρ 1 bis 14ρ8 und den Kontakt 15 hm 1 wird das Relais-S* eingeschaltet. Der Kontakt 15 hm 1 ist in nicht dargestellter Weiseίο SZ 4 and SHl effective when no other call stimulus is effective in this identifier, ie the contact 2gse is in the idle position. As stated above, no circuit for one of the relays P1 to P 8 can be established via the contact lOsz 4 of the relay SZ 4, which is switched on when the calling station is identified (see FIG. 2). The relay -S * is switched on via the contacts 12ρ 1 to 14ρ8 and the contact 15 hm 1. The contact 15 hm 1 is not shown

Der Kontakt 4s (Fig.3) des zentralen Wegesuchers WS ist betätigt. Über diesen Kontakt 4 s und den Kontakt 5 sz 4 wird das Relais SB 4 des Identifizierers TAS eingeschaltet. Durch die Einschaltung des Relais SB 4 wird über den Kantakt 3 si) 4 das Relais SZ 4 ausgeschaltet. Über den Kontakt 6 sb 4 wird das Trennrelais TR zur Freischaltung des Identifizierers eingeschaltet. Auf diese Art und Weise wird verhindert, daß der Anruf anreiz der Sprechstelle iV40 bei Besetztsein aller für diese Sprechstelle belegbaren Zwischenleitungen »dauernd« den Identifizierer TAS und die zentrale Steuereinrichtung ZS belegt, ohne daß eine Verbindung zu einer freien Übertragung hergestellt werden kann. Das Relais SB 4 wird in nicht dargestellter Weise für eine bestimmte Zeit über den Punkt VZ gehalten und beispielsweise nach 30Sekunden erst ausgeschaltet. Hierdurch kann.der Teilnehmer den Anruf anreiz für diese Zeit nicht absetzen, und andere Sprechstellen können identifiziert werden.The contact 4s (Fig. 3) of the central path finder WS is actuated. The relay SB 4 of the identifier TAS is switched on via this contact 4 s and the contact 5 sz 4. When relay SB 4 is switched on, relay SZ 4 is switched off via contact 3 si) 4. The isolating relay TR is switched on via contact 6 sb 4 to enable the identifier. In this way it is prevented that the call incentive of the station IV40 at Besetztsein all assignable for this station intermediate lines "permanently" the identifier TAS and the central control device ZS is without a connection to a free transmission can be established. The relay SB 4 is held in a manner not shown for a certain time above the point VZ and only switched off after 30 seconds, for example. As a result, the subscriber cannot send the call incentive for this time, and other microphone units can be identified.
