Circuit arrangement for making connections of different values over the same connection devices

Patented in the German Empire on October 27, 1927

The invention relates to circuit arrangements for telephone systems for manufacture different-valued connections via the same connection devices and the purpose of special maintenance processes with high-quality Make connections with as few tools as possible.

This is achieved by the fact that the incoming, high-quality connections .auf an ordering connection switching relay of a connection device for outgoing high-quality connections are used to prepare a counting circuit (e.g. for multiple counting).

ig By the arrangement according to the invention it is now possible to switch on and prepare for counting by means of a switching device to bring about, so that besides the achieved by this multiple use per se Saving a switching means still special advantages in systems in which certain other switching processes are carried out by using a relay multiple times, can be achieved by the fact that the functions of switching and counting preparation, which were not previously carried out by a relay can be transferred to a relay.

Figs. 1 and 2 show as an embodiment of the invention a main and sub- Exchange. The line selector of the sub-exchange, through which both ordinary Subscriber lines as well as trunk lines can be reached for making incoming calls high quality connections from the main to the sub-switch and outgoing high quality connections are used by the sub-switch.

The invention is not restricted to this exemplary embodiment.

The mode of operation of the arrangement will now be described using the illustration.

First, a low-order connection between the two subscribers iV ¹ and iV ^{2 will be} described. If the subscriber N ¹ lifts his receiver, the relay R of the preselector assigned to the subscriber is excited in a known manner via earth, relay R, contact 3 t, subscriber N ¹ , contact 1 t, resistor Wi, battery, earth. By energizing the relay R , a preselector is started for free choice in the usual way. Does the selection have one; Free line selector LW found, the relay T of the preselector VW speaks via earth,

Alfred Scheunert and Frans Simon in Berlin-Charlottenburg.

Winding II of relay B ₁ winding II of relay A ₁ contacts 25 k, 17 x, winding I of relay C, resistor Wi, c-arm of preselector VW, windings I and II of relay T ₁ contact 6 r ¹ . The subscriber line is switched through to the line selector via contacts 2 t and 4 ί, which further excites relays A and B via: earth, battery, winding I of the relay ^, contact το z, α wire, contact 2 t, subscriber N ¹ , Contact 4 t, windings I and III of relay B is connected, after relays A, B and C were already energized when the line selector was activated in the just described excitation circuit of relay T. The relay C puts its armature from the contact 14 c to the contact 15 c and thereby makes the holding circuit of the relays C and T independent of the head contact 25 k. If the subscriber iV ¹ now sends out current impulses to adjust the line selector by pressing his dial, the relay A is de-excited according to the current impulses sent, so that the line selector LW by energizing its lifting magnet H via earth, contacts 48 p, 49 c, 50 a , 55 Mj 57 w> lifting magnet H ₃ battery, earth is lifted according to the current surges. During the first series of impulses, relay V was kept energized via earth, contacts 48 p, 49 c, 50 a, winding II of relay V, battery, earth using a short circuit, winding I of relay V and contact 39 ν , so that after the closing of the head contact 46 k an actuation of the rotary magnet D of the line selector was impossible. After the first series of impulses, the relay V drops out, so that the relay U is excited via: earth, contact 48 p, head contact 46 k, contacts 47 v, 52 c, winding II of relay U ₁ shaft contact 57 a ¹ , lifting magnet H, Battery, earth done. The solenoid H is not excited in this circuit. If the subscriber now sends the second series of impulses by pressing his dial, the rotary magnet D of the line selector is pulsed via: earth, contacts 48 p, 49 c, 50 a, 56 w, 54 s, rotary magnet D, battery, earth. The relay V is also excited during this series of impulses in the circuits described above, so that during the pulse signal of the relay U via: earth, battery, winding I of the relay U, contacts 39 v, 41 u, 42 c, earth holds . After the second series of impulses has elapsed, relay V drops out and, since relay U remains energized as a delay relay, the line selector set can be checked via: earth, contacts 42 c, 41 u, 40 v, winding ¹ ! and II of the relay P ₁ c -'- arm of the line selector, relay T ² , battery, earth to the desired subscriber. If the participant is free, the relay T ² responds in the test circuits just described. By energizing relay P , relay V is re-energized via slow breaker, contacts 64 μ, 62 y, 61 s, 60 p, winding III of relay V, battery, earth, so that the high-resistance winding II of relay P is switched off and the As a result, the participant is blocked against any further occupancy by increasing the potential on the test wire. Simultaneously with this, the connection of the ringing current takes place via: earth, battery, contact 2.7 v, winding I of relay Y, contact 28 a, transformer winding, contact 34 p ,, α ¹ -Arm of the line selector, subscriber N ² , i ^ - Line selector arm, contacts 31p, 32 [X, 3Oy ₁ ground. The relay Y does not respond to this ringing current.

If subscriber N ² answers, relay Y speaks about: earth, battery, ringer, contact 37 v, winding I of relay Y, contact 28 a, transformer winding, contact 34 £, a ^ arm of the line selector, subscriber N ' ² , & ¹ -Arm of the line selector, contacts 31 p, 32 x,? Py, earth and after de-energizing relay V by opening contact 62 y via: earth, winding I of relay Z ₁ transformer winding, contact 31 ρ, δ ¹ arm of the line selector, subscriber N ² , α. ¹ -Arm of the line selector, contact 34 £, transformer winding, contact 28 a, winding I of relay Y, contact 38 v, resistor Wi, battery, earth. In this circuits ^r w ill also the relay Z energized, the s prepared by closing contact 11 the Zählstromkreis.

If after the end of the call the subscriber iV ¹ hangs up his receiver, relays A and B drop out as a result of the interruption of the holding circuit. As a result, the relay Y is caused to drop out through the disconnection of the excitation circuit via the contact 28 α. After some time, the relay C is deenergized as a result of a short circuit in its winding I via the contact 26 α , so that in the circuits earth, contacts 14 c, 11 s, resistance Wi, c arm of the preselector, counter winding ZW (parallel to winding II of the Relay Γ), contact 5 t, battery, earth the meter is affected. By short-circuiting the winding II of the relay Z via the contact 14 c , the relay Z will drop out after some time and disconnect the counting circuit. The low-order connection is counted automatically via a contact of the trip relay in series with the counting contact of the counting transfer relay serving as a feed bridge relay. Regardless of the status of the called subscriber station in conjunction with ²

the de-energization of the still energized relay will now take place, so that the line selector by energizing its rotary magnet via: earth, contact 48 p, head contact 46 k, contacts 47 v, 51c, 53 u, 542, rotary magnet D ₁ battery, earth in the same Decade to the end of the same as a self-interrupter with the relay U (earth, battery, contacts 44 d, 47 Vj 46 k, 48 p, earth) and then triggers in a known manner.

A connection between the subscriber 2V ¹ and a switching center VS is described below. If the subscriber iV ¹ lifts his handset, as described above, first the assignment of a preselector, which is then followed by the free choice of a free line selector, then the line selector is set in the manner indicated above. The line selector arms now do not reach the connections of an ordinary subscriber, but run on the contacts of a connecting line VL a, VL b '. If the ringing current is now transmitted from. Earth and battery via contact 37 V ₁ winding I of relay Y ₁ contact 28 α, transformer winding, contact 34 £, ö ^ arm of the line selector, α ¹ wire, VLa, contact 65 t ' ¹ , 67 c ¹ , winding I of the relay A ¹ , capacitor K, connecting line VL b, Z ^ -Ader, & ¹ -Arm of the line selector, contacts 31 p, 32 x, 30 y, earth, this way the relay A ^{1 is} excited, which its winding II over : Earth, contact. 106 o ¹ , 107 r, winding II of relay A ¹ , battery, earth puts in a hold circuit; At the same time there is also an excitation of the relay H ¹ via: earth, contact 108 a ¹ , winding I of the relay FP, battery, earth. In the circle earth, contact 98 c ¹ , call lamp AL, contact 97 h ¹ , resistance Wi, battery, earth the call lamp is made to light up, so that the officer at the operator station is given the signal by this signal that there is a call. Put the

If the officer puts the interrogation plug ASt shown in Fig. 2 into the connecting latch, then in the circuit prepared by the contact 94 h ¹ for the winding III of the relay C ^1, an excitation of the relay C 1 occurs, which occurs after short-circuiting its winding I via the contact 96 c ¹ in the circle: earth, interrogation plug ASt ₁ connecting pawl, contact 96 c ¹ , winding II of relay C ¹ , battery, earth holds. By energization of the relay C ¹ excitation occurs the relay 7 ¹ in the holding circuits of the relay H ¹ via earth contact 99 c ^1, winding II of the relay FI ^1, winding II of the relay J ^1, contact 97 h ^1, resistor, battery , Earth. By separating the contact 98 c ¹ , the call lamp is switched off. A monitoring relay 5 "is switched on in the connecting line, which is in the circuit: earth, winding I of relay S, contacts 69 s ¹ , 70 u ¹ , 77 Ii ¹ , transfer winding, contacts 68 c ¹ , 66 h ¹ , o ^ Vein, α ¹ -arm of the line selector contact 34/1, transformer winding, contact 28 a, I winding of the relay contact 38 v Y _1, Wi resistor ₁ is energized battery earth. In the same circuits a excitation is of the relay Y. By moving the contact 111 s , the relay R is excited via earth, contact 102 c ¹ , in S ₁ relay R ₁ battery, earth, so that the relay A ¹ is de-energized by disconnecting the contact 1077.

The officer accepts the request of the participant and connects him by means of the device available to her, shown in Fig. 2, with the desired Attendees.

The other connecting devices are not shown in the figures because they have no meaning for the idea of the invention.

If after the end of the conversation, subscriber N ¹ hangs up his receiver, relays A and B are de-energized as a result of the interruption of the subscriber loop. The relays Y and 6 * are therefore de-energized by the separation of the contact 28 α. By falling of the relay 5, the relay U ¹ is in the circle: r earth contacts 101, ioqs, winding I of the relay U ^1, battery energized earth, since the relay R as the delay relay energized in spite of separation of the contact 111 s for some time remain. By response of the relay U ¹ , which is in a holding circuit via: earth, battery, resistance Wi ₁ winding II of relay U ¹ , contacts 71 u ¹ , 77h ¹ , transformer winding, contacts 68 c ¹ , 66h ¹ , «! -Wire , α ¹ arm of the line selector, contact 34 ^., transformer winding, contact 29 a, winding II of relay C, winding III of relay X , the connection is maintained due to simultaneous excitation of relays C and X in the same circle, despite the Winding I of relay C was short-circuited via contact 26 α.

By energizing the release relay C via the switching devices of the called attendant console, the release of the existing connection is withdrawn from the influence of the calling subscriber in order to enable a multiple counting by an officer before the release.

Let us assume that the officer established a high-quality connection. Since these connections require an increased fee, a multiple count by the officer is required. This multiple counting can be done in such a way that by repeatedly pressing the counting key ZT to the fr-wire

(see Fig. 2) ian earth potential. This results in an excitation of the relay Z ¹ in the circle; Earth, fence button ZT, interrogation plug ASt, £> ² wire, transformer winding, contact 90 μ ¹ , winding II of relay Z ¹ , contact 89 h ¹ , resistance Wi, battery, earth. Due to the current impulses sent out depending on the value of the connection, the relay Z is switched via: earth, battery, resistor Wi, contact 75Ä ¹ , transformer winding, connecting line VLb, ^ -Ader, Z ^ -Ärm of the line selector, contact 31 />, winding I des Relay Z actuated in the same way as relay Z ^1. The contact 115 will then close abruptly, so that the counter ZM in the circle: earth, contacts 12 y, 13 χ , ils, resistance PFi, c-arm of the preselector, counting magnet ZM (parallel to winding II of the Relay T), contact 5 t, battery, earth is actuated according to the number of current surges. The counting current surges now run via the contacts of the relays X, Y, Z, which are in series, while the counting current surges in the case of low-order connections were given via the contact of the trip relay C. The relay X is thus used with the counting transmission relay Z to generate counting current.

The same relay X is used in the case in which the line selector LW is used to establish an incoming high-quality connection, ie when the line selector LW z. B. achieved via a preselector parallel to the shown preselector VW from the remote officer and, for example, is set to the subscriber iV ² already used by another connection, used for connection by applying a ground potential to the two wires α and b Relay B is brought to drop out, so that an energization of the relay X in the following

Circuits comes about: earth, pole

of the battery, resistor Wi, contact 24 c, windings II and I of relay X ₁ contacts 22ij 21 b, shaft contact 18 w of the line selector LW, contact 19 v, windings II of relays A and B. The resistances in this circuit are dimensioned in this way that an excitation of the relay B can not take place in this circle. By closing the contacts 35 χ and 36 χ , the incoming high-quality connection is switched to the subscriber N- who is already being used by another connection. Once the count has been completed, the officer will pull the connection plug out of the latch and, by de-energizing relay C ^1, de-energize the relays that are still in the working state, so that the line selector is shown in the same way as shown in the previous description of a connection establishment. comes to rest.
