Description

Hall Tung arrangement Kr telephone systems with selector operation directed at the non-directional lines are additive to Patent 588 062 The main patent relates to a circuit arrangement for telephone systems with selector operation, wherein non-directed Leitungen.gerichtet are and after the initiation, but before Vollendun- the setting of a number surge recipient over an outgoing connection line of other traffic direction reachable number current impulse receivers is set depending on the direction selected by the calling station. With this arrangement% of the load connected to the second transport direction group selector is achieved via a mixing selector, which is established at the start of setting of the donor to the 'different directions access the first group selector in free choice on a free group selector to the second transport direction, and these finally occupied, without that the final choice of this traffic direction has already been determined. The invention represents an improvement of the arrangement of the main patent insofar as it avoids, on the one hand, any unnecessary occupancy of a number current impulse receiver for the second traffic direction, and, on the other hand, the free selection of the mixed selector leading to the second traffic direction, which begins after the occupancy of the first group voter, which may last for a long time It may take time for the first group selector to switch to the second traffic direction beforehand.

It has already been proposed for direction elimination - an arrangement has been, which checks whether when a code number arrives this more current surges contains or does not contain the number of rushes intended for the first direction of traffic, and in the first case always immediately a connection line for the second traffic direction proven. As the code number for the first direction of traffic from a single power surge exists, the second traffic direction always becomes one after the first power surge Stronistoßzeile shows what has the disadvantage that for the first direction of traffic, only this one code number and not any other code numbers that make the selection several participant groups possible, can be used.

It is already known also, through pre-mixed voters, which reaches a pre-arranged group selector - len -%,%, grounded, different directions of traffic - from # zuwüh. With these arrangements, the choice of each traffic direction requires two rows of identification rushes, of which the second series of rushes is only used for reversing. control of the preset mixer selector is used, so it is lost for the setting of the number surge receiver occupied by the mixer selector. In addition, the reversing of the mixing selector to the second traffic direction is carried out in such a way that the first surge of the second series of identification current impulses serves to prepare the reversal in the occupied mixing selector and is no longer used for reversing the next voter. Finally, the known arrangement makes it necessary to assign a -yLitllauf-r to the upstream group selector, in which the two series of identification currents are evaluated. In contrast, the invention has the advantage that only a single series of identification current impulses is required to select two different traffic directions, which is also used to set the number current impulse receiver for the two directions of traffic, without a current surge of the current impulse sequences characterizing the two directions of traffic being lost. The directional identification and setting of the occupied low-voltage surge receivers is therefore carried out in a simpler and faster manner. - In addition, the cost of switching means is also lower.

According to the invention this is achieved in that switching means are provided are which a number surge receiver provided via a pre-set mixer selector only after expiry of the optional setting of one in a certain traffic direction leading other number current impulse receiver serving part of a current impulse series when the first rush of electricity is sent, indicating a different traffic direction block this row and at the same time switch the current impulse to the mixer using the mixer selector finally - assigned N number surge receiver transmitted as the first setting current surge.

Further characteristics of the invention are that the first of the current impulses to be passed on via the connection line for a certain traffic direction, in addition to blocking this line, is also used to set downstream number current impulse receivers and that the transmission of the first current impulse * is started by a current impulse reception relay and one controlled by it Auxiliary relay is terminated, while the subsequent current surges are passed on exclusively by the auxiliary relay. , By the last arrangement, the first impulse is corrected only when the following current pulses are passed in the same way. Accordingly, a first current surge can be used to carry out certain functions (e.g. blocking) and, despite the shortening it has experienced as a result, it can still be transmitted as a full current surge.

In the drawings, two exemplary embodiments of the invention are shown, however, to which this is not limited.

FIG. I shows a group selector GW.i which has access to the group selector GTY: 2. In parallel to the group selector GW: 2, a mixing selector MW is provided, via which devices receiving number currents can be reached. A pulse transmission Ue is arranged in front of these, the purpose of which will be explained later. The MW mixer selector is equipped with a presetting and provides free connection lines Las, Lbs, Lcs and Lds in preparation. In addition to the switching arms sca, scb, scc, the group selector GW2 also has a decade switching armDek. This switching arm is used during the lifting movement of the group selector to influence the contacts, which stops again when the rotary movement is made. . - Figure 2 illustrates as another embodiment a change in the group selector GW: 2 represent, in which at certain impulse dialing number rows, the completion of the setting is prevented. This is e.g. B. the case when digits are dialed that indicate a connection to a receiver that can be reached via the mixer selector MW.

For the manufacture of compounds of 'the group selector GW 2 are di' e Root i selected to 5 and is intended for connections which are guided through the mixing selector MW, the codes 6 to o. In, the following first the preparation of a compound for adjusting the Selector GW 2 can be described by the code number 5 .

Assuming that the group selector OW i is set, the following circuit has come about: test switch on line Lc, switching arm sc of group selector GW i, winding I of relay C, head contact 2.1 k of - group selector GW -9, battery, earth . The relay C has been energized and has actuated its contacts. The winding II of the relay C has been switched on by contact i c , so that a holding circuit for the relay C has come about independently of the head contact 2.1 k. A circuit for the solenoid and H 5 C by contact was by contact c 3 verbereitet a test circuit for the group selector GW. 2 Contact 6 c prepares circuits on the IIIIW mixer selector.

As already mentioned, the mixer selector.IVIW is equipped with a presetting and is located on a free LasILds line that is not in use. The relay P i of the mixer 11, IW is excited via the Wich: -lung II- in the following circuit: earth contact 34P 2, winding # g II d6s relay P i, switch axis zud, line -Lds, battery, Earth. The relay P i has its contacts actuated # and by opening the contact 14P I interrupted the circuit for the rotary magnet Dinw of the mixer selector MW #. A circuit for energizing relay P.2 has been prepared at contact i5p i. The contact 16p i has been opened. If current surges are sent out by the calling station, relay A is energized in surges via its winding II. When the Erreting ReliLis A the solenoid of the group H obtained through the contact selector 8 a a S tromstoß well Däs relay P over its Widzlung III by the contact 9 a. The solenoid H and the relay P are actuated. - While the solenoid H is operated in a current impulse when the further current impulses are emitted, the relay P remains energized because it works as a delay relay by short-circuiting its winding II through the contact 2: 2 p. Hereby is kept open also- the contact 23 while P of receipt of pulses, so that the contact decade Dek II of the relay Y than the winding - -can influence. In the first stroke of the group selector, the head contacts 21 k and 2-2 ' k have been actuated. The circuit for the rotary magnet D of the group selector is prepared through contact 22 k. However, this circuit cannot yet be established during the lifting movement, since the contact 21 p of the relay P is open when current surges are received. If the voter has been raised to decade 5 after five strokes have been sent out, relay P will drop if relay A is over- excited for a longer period of time. This closes the contact - ip, so that the following circuit is established for the rotary magnet D : earth, battery, twist magnet D, contacts 22k, 2ip, ioa, earth .. The rotary magnet is excited and switches the switching arms in the selected decade one step. Further. The contact 23 d'des Drebmagneten D is closed, whereby the relay A comes through its winding III to respond. The relay A opens the contact io a, whereupon the Deehmagnet drops. The contact. 23 d opens again. The Relai - s A drops. The contact ioa closes -, vieder the circuit for the rotary magnet. This reciprocal - Game "rird SO continued until * via the switching arm soc the group selector-GW, a test circuit has come about. When relay P dropped, the following circuit was established for winding II of relay Y: earth, battery, winding II of relay Y, contact 2,3 p, decade contact - Dek in position i to 5, contact 6 c, earth. The relay Y is energized and turns on via contact 1 8 y in a hold circuit that runs over winding I. The relay Y opens the contact 1 9 y, so that the further switching earth for the rotary magnet Dmw the mixing selector MW is turned off and the Mischwäh # coupler det a further circuit for example in blocking - Leitutig LasILds part -one not follow ei to-the calling subscriber .

If the group selector finds a free line, relay P responds. The relay P activates its contacts and opens the working circuit of the rotary solenoid at contact 2 1 p. Contact 2--, p blocks the line found. The speech wires are switched through via Konta # Ide 7P and 24P. The shaft contacts 24w and: 25zu were opened when the selector was turned for the first time.

If the connection is to be released, relay C is brought to drop by opening the prefader Lc. Relay Y drops out. - By opening the contact 5 c - the relay P is de-excited. The Kontalirt 21 p is closed, whereupon the mutual play between the rotary magnet D and the winding III of the relay A begins and the selector is switched on until it has reached its rest position. In this the head contacts are -actuated so that the arrangement can be assigned again.

If, when the group selector GW2 is set, all connections of a desired decade are occupied, the selector rotates through to position ii. In this the shaft contacts: 26 zu ii and 27w II are closed. The following circuit for winding II of relay A is established via contact 26 w ii: earth, battery, winding II of relay A, resistor PVi, contacts 26 wii ,? - c, left winding of transformer earth. In this circuit, the relay A is kept energized so that the rotary device D no longer receives current. The subscriber receives the busy signal bes, which is induced via winding I- of relay A, contact : 27 wii, capacitor Ko.

If a subscriber establishes a connection that is to run via the mixed selector AIIW, the group selector GW2 is assigned in the manner already described. Assuming that the participant has dialed dib number 7 , the decade contact Dek is advanced to contact 7 . If the decade contact reaches contact 6 when the sixth current impulse is sent, the following circuit is established for relay P 2 of the mixer selector MW: Earth-, contact -6c, decade contactDek in position -6 to io, contacts -oy, 15 p i, i2a, windings I and II of relay P 2, switching arm wc, line Lcs, relayGi, battery, earth. In this electrical circuit, the relays C i and P 2 are actuated. The relay P 2 switches through the speech wires via contacts 31P2, -and 3-p: 2, so that the sixth current impulse, which caused the relay A to respond via the winding II, still actuates the relay Ai. ' The RelayAi serves as a current impulse iCi transmission relay for generating current impulses for setting downstream receivers. When relay P2 responds, contacts : 28 p 2 and 29p2 are closed. - This creates a holding circuit across the winding of the relay P2, which is independent of your IielzadenkontalztD-ek. Through contact 33 P 2, earth is applied directly to the switch arm of the mixer selector MW. Contact 3023 will be opened. All relays P i of those mixer selector MW that are also preparatory on the line LasILds, the current is withdrawn by applying earth directly to the switching, brmwd at contact 33P: 2, so that the relays of these selector drop out and the continuation of their Initiate mixed selector for the purpose of providing an outgoing line. The relay P i is kept energized by closing the contact 30P 2, so that the mixer selector MW is not indexed by keeping the contact 14P 1 open. 'The seventh emitted by the participants Stronistoß runs except for Relay A also via line Las and arrives at your relay A i, which transmits this current surge in later manner to be described to a downstream recipient. If the seventh and last current impulse of the current impulse series has arrived, relay F of the group selector GW: 2, which was energized during the current impulse, is brought to fall after this has ended. As a result, the rotary magnet D is switched on in the manner already described. The voter GW: 2 now turns a step. In the position now reached, a circuit is established for the test relay P of the group selector via the resistor i Wi, which runs across the closed contact 17Y, so that the selector GW2 is shut down. Two power surges have been sent to the transmission Ue. If a subscriber dials at a time when the mixer selector MW has not yet provided a free line, the following switching processes take place on the mixer selector. The Relals F i ax works intermittently with your rotary magnet DMW for the purpose of switching the mixer selector. When dialing, contact ii a is closed. If the contact 16p i now also closes, the winding I of the relay Y receives current. The iSy contact is closed and the relay Y is kept energized via its winding I. The igy contact prevents the mixer selector from being set by disconnecting the earth from the circuit of the rotary magnet. A connection via the selector GW2 takes place smoothly. However, if the participant has chosen one of the code numbers 6 to o, then when the current impulse gaibe ends when the relay P drops, the selector GW 2 is his. Turning in the selected decade does not stop your first step, but rather, because contact i7y is open, rotated to position ii. In this, the Wick 'lung energized II of the relay A through the contacts ii 26w and 2c. The calling subscriber receives the busy signal.

The mode of operation of the transmission device Ue is described below. The first current impulse influencing relay A i can only take effect after relay P2 has been addressed. However, the response of relay F: 2 is also determined by this current impulse (via contact 12 a). The current impulse coming to the relay A i is thus shortened. When the relay A i responds, the contacts 37a1 and 38aI are switched over, as a result of which the alternating current source We is applied to the line La 3, Lb 3 . The contact 36a i causes the switching on of the relay A 2. The contacts 4o a 2, and. 41 a - j ow switch the AC power source We of - the line La, 3, Lb 3.an so that the closure is of the contacts 37a and 38a I i started by the response of the current surge RelaisA2, extended, and indeed the Release time of relay A: 2. The relay X is switched on by contact 42a: 2. The relay X is maintained via the contact 43 x Via Konta, kt 39 C i of the relay # G i and separates the alternating current source We from the contacts 37a 1 and 38a i via contacts 44 x and 45 x. The next current impulse that reaches relay A i is no longer transmitted by means of contacts 3 7 9 1 - and 3 8 a i, since dig contacts 44x and 45-- are open. Only when the relay A: 2 responds, the alternating current source T-Ve is switched on via the contacts 40 a 2 and 41 a? Trip is the drop in Relads -A 2. This transfer thus a reduced incoming surge is extended while: all subsequent power surges can be passed in Invariant 7 nderter way.

FIG. 2 shows an exemplary embodiment of a group selector which can be used in place of the group selector GW 2 of FIG. In this case, if you choose Kenh # iffern,. If the receiver can reach the mixer selector, the setting cannot be completed. As already described, when the decade contact Dek of the group selector GW: 2 was set to contact 6, the relay P 2 was actuated. In the case of the group selector GW ->'according to FIG. 2, the lifting magnet H and the rotary magnet D Jes selector GW2' is switched off by contact 5: 2 p 2, so that the receivers which can be reached via the mixer selector MW are further used Current surges can no longer influence the solenoid of selector GW2 '. This prevents useful power consumption and premature wear and tear of the selector GW2 '.

If, when the V & .: connection is triggered, when relay C drops, contact 6 e is opened and the kelals P: 2 is brought to Ab # a11, then rotary magnet D receives current and. switches the selector GW: 2 'home in the same way as this was described for the selector GW: 2.
