Description

Circuit arrangement for voters with movable switching elements in the individual contact positions to be operated contacts of the contact bank, in particular For telephone systems In telecommunication systems and in particular in telephone systems with voter operation are in a voter for connections in individual traffic directions Carry out switchovers to switching operations that occur in connections in other traffic directions can be carried out in a certain way, changed or suppressed entirely. In the case of connections in only one or a few traffic directions, you often have to Switching operations are carried out for connections in other traffic directions not acceptable. So far these switchings have been made for this purpose only Serving voter contacts (decade contacts, collective contacts) or via a special, Contact bank to be coated by an auxiliary switching arm with one of the capacity of the Voter corresponding number of bank contacts or via a follower and if necessary Control relays which can be switched on via the switching means mentioned are initiated or carried out.

The invention shows a way to make this special, the economy Auxiliary equipment that may have a considerable influence on the systems As far as possible to avoid with the voters, whose switching elements moved during the setting in the individual contact positions the bank contacts of the connecting lines and Actuate mating contacts existing contacts of the contact bank (pressure contacts).

The invention consists in that the mating contacts to the bank contacts of the connecting lines to be determined by the similarity of the connecting lines Groups are grouped together and over the feed line to the mating contact groups switched-on switching means that are required for connections in certain traffic directions Initiate switchovers in the voter. 'According to a further embodiment of the invention it is not always necessary that the mating contacts of all cores are grouped together will. It is often sufficient if this only applies to some of the mating contacts, e.g. B, only for those of a speaking vein or the test vein. This is e.g. B. then the Case when there is change, suppression or execution of a special Switching process via the outgoing, via the bank contacts of the voter connecting cores, but not over all cores or one in the access Auxiliary relays of the respective outgoing contacts that are connected to a group of mating contacts or makes corresponding switchovers in the voter depending on the direction of traffic.

Similar connecting lines can be one or several numerical Form groups (decades). Each group of mating contacts then includes the mating contacts one or more numerical groups (decades).

Several groups of similar connections can also be used in a numeric Group (decade). Then the mating contacts are this numeric Group (decade) combined into several groups.

The invention is not only for performing switchovers Connections of certain outgoing, but also to carry out switching genes for connections of certain incoming traffic direction or traffic directions applicable. By grouping together the opposing contacts in call finder contact banks can perform the switching operations required for calling subscribers of a certain class without special training of the connection lines or the current paths for transmission initiated by call incentives. Also specially trained or equipped Connecting lines, e.g. B. Interconnection lines from another office, if applicable only a single one, can make switchovers in the connection system necessary.

A connecting line, e.g. B. a company management; can in the Contact banks of line selectors and / or call seekers themselves to multiple groups Connections of the same type belong to a dial-up option for outgoing connections Call or to enable individual counting for incoming connections.

In the drawings are some embodiments of the invention shown.

Fig. I shows a group selector, in which when connections over the decades I to VIII during the. Passing on power surges a control voltage to be applied to the outgoing b-wire, while for connections over the decades IX and X the connection of such a control voltage does not have to take place.

Fig. 2 shows a group selector, in which when connections over decades I to IX are counted at the end of the connection, while for connections over the decade X during the call the count is to be carried out. The marking, which counting comes into question is done by grouping together the mating contacts a speech artery.

Fig. 3 shows a group selector, in which when connections over decades I to VIII the count at the end of each connection and for connections to be carried out over decades IX and X during the conversation. The marking for the type of counting is done here by grouping together the mating contacts the test wire.

Fig. Q. shows a line selector to the individual line subscriber and company managements are connected. When setting the line selector for a decade (VIII) to which company managements are attached the connection depending on the grouping of the mating contacts the ringing current to the a- or b-wire as well as with the choice of certain participants of a four-person company management also the connection of another ringing current source.

Only the details absolutely necessary for an understanding of the invention are shown. Sa, Sb and Sc are the switching elements (switching arms) that are moved when the selector is set, to which no feed lines to the selector are connected and which, when the selector is set to an outgoing connection line, press the mating contacts of the respective connection line reached onto its bank contacts. With KS i, KS 2, KS 3 etc. the individual contact steps of the selector are designated. Accordingly, for example, in the decade I after the first contact step, i.e. in the first contact position, the mating contacts Ka il, Mb il, Kc il to the bank contacts Kca i'l, Kb: i'l, Kc i'l, after second contact step (second contact position) the mating contacts Kca 12, Kb 12, Ke 12 * pressed against the bank contacts-Ka i'2, Kb i'2, I @ c i'2 etc.

Various voter systems achieved. In the case of connections over decades I to VIII, the setting is subordinate Apply selector control voltage to the outgoing b-wire. This control voltage is allowed cannot be created if the group selector is one of the decades IX and X outgoing connection lines.

Since only via the b-core for connections over decades I to VIII a certain switching process (application of the control voltage) is to be carried out only the mating contacts of the b-core are combined into two groups. The one group includes the counter contacts of the Ibis VIII decades. The second group includes the counter contacts of decades IX and X. The mating contacts of cores ca and c of all decades are multiple switched.

The group voter will be one of the decades I through VIII, for example before Decade VIII, set. The one that can be reached via contact step KS 5 Connection line VZ 85 is free and is in use. The switch arms Sca; Bring Sb, Sc the mating contacts Kca 85, Kb 85, Kc 85 in contact with the Bank contacts Ka 8'5, Kb 8'5, Kc 8'5. The test relay P, to which + through the contact i c des Occupancy relay is applied, responds. It blocks the connected connection line at contact 2p VL 86 and closes the contacts 3 P, 4 P, 5 P in the speech wires, the closure of contact 4 P, via which the incoming b-wire with the mating contacts Kb g and Kb io of decades IX and X are ineffective, because none of these Mating contact is in contact with the bank contact of an outgoing connection line.

In the group selector for setting subordinate voters incoming current surges are passed on through the contact 6 a via the a-wire, the mating contact Ka 85 and the bank contact Ka 8'5 to the wire VZ 85 a . When the first current surge is received, a control relay (not shown) is excited in a known manner, which remains activated during the current surge and by means of its contact 7v the control voltage across the resistor 8 to the mating contacts Kb 8 and thus to that of the bank contact Kb 8'5 outgoing wire VL 85 b) switches on.

For example, if the group selector is set before the X decade and if he seizes the connection line YL i02 on the second contact step, then during the transfer of power surges, the control voltage to the VL io2b wire is not created because the incoming b-core is direct and not via a v-break contact connected to the mating contact Kb io2.

The connection or non-connection of the control voltage to the b-wire can also be done in groups with multiple switching of the b-mating contacts of all decades Summary of the c-mating contacts are made. Such a circuit is to be implemented a different count is shown in FIG. One in front of the c counter contacts of the decades IX and X as in Fig. 3 lying auxiliary relay in the test or blocking circuit responds, connects by switching off the changeover contact 7 v / g v the incoming b-core directly with the b-mating contacts.

In the arrangement according to FIG. 2, the counting for connections over the decades I to IX is to be carried out at the end of the connection and for connections over the decade X during the call. The necessary switchovers are carried out by combining the mating contacts of the b-wire, via which the counting initiation criterion or counting current impulses are given, in two groups Kb i to Kb g and Kb io.

For connections that run over one of the decades I to IX, is the b-wire is switched through at contact io c. The winding II of the counter relay Z is separated at contact ii c. Only after the calling party has given the final signal and drop of the occupancy relay is winding II of the counter relay Z via the contact ii c applied to the outgoing b-wire. The counting relay Z responds when in one Downstream voter counting potential is applied. As is known, the interruption of the outgoing connection via the group selector prevents the counting is carried out. This can e.g. B. be done in that the contacts 21 c and 22 P + is applied to the outgoing c wire. The connection path via the group selector is then only disconnected after the relayP has dropped out, i.e. only after a time during which the count is carried out safely.

The winding I of the counting relay Z is in the one to the mating contacts Kb io leading branch from the incoming b-core and is, as none of the mating contacts Kb io is in contact with a bank contact Kb io 'during the connection unaffected.

Only with a connection over the decade X, e.g. B. with the connection line VZ, io2, the winding I of the relay Z is switched on and z. B. after reporting the called subscriber flowed through by electricity. The counting initiation criterion or counting current impulses from a downstream metering current impulse transmitter operate the counter relay Z in the following way: - on a downstream selector or transformer, VZ io2b, Kb io'2, Kb 102, 4 P, ZI, Dr II, -f-.

The identification of whether a count is made after the connection or is to be carried out during a call can, as FIG. 3 shows, also via the test and blocking veins take place. The b counter contacts of all decades are then, im In contrast to the arrangement according to FIG. 2, switched multiple times. The c-mating contacts are summarized in two groups Kc i to Kc 8 and Kc g and Kc io, since it is assumed that for connections over decades I to VIII a count is made after the end of the call and for connections over decades IX and X to take place during the call Has.

In the case of connections over decades I to VIII, the counter relay Z is only present on the outgoing b-wire after the occupancy relay has dropped and contact 12 c has closed. It is activated when counting potential - is applied at a downstream point of the connection path: -, b-wire of the occupied connection line, e.g. B. VL 81b, Kb 8'1, Kb 81, 4 P, 12 c, 13 h, Z, +.

In the case of a connection via one of the decades IX and X, the relay H is energized in the blocking circuit via the emitting c-wire. It opened the contact for 13 h. Contact 14 h is closed. When the time for counting occurs, e.g. B. when reporting the selected subscriber, counting potential is applied at a downstream point on the connection path. The counter relay Z responds to: -, b-wire of the connection line, bank contact and associated counter contact, 4 P, Dy 1I, 14 h, Z, +.

4 company lines are connected to the line selector according to FIG. By grouping together the mating contacts of the a-, b- and c-cores, the connection of the or a certain ringing current to the outgoing a- or b-core takes place in the manner peculiar to the selected subscriber when each company line or two-way subscriber chooses. Only individual line participants are connected to Decade VII. The mating contacts of all three wires b and c of this decade are switched multiple times. The mating contacts of all three wires of Decade VIII are combined into two groups. The mating contacts Ka 81, KU 8 2, Ka 8 5, Ka 86, Ka 89 and the corresponding b-mating contacts each form a first and the mating contacts Ka 83, Ka 84, Kä 87, Ka 88 and Ka 81 ° and the corresponding mating contacts the b-core each form a second group. The groups of the c-mating contacts do not agree with these two groups. One group is formed from the mating contacts Kc 81, Kc 83, Kc 85; Kc 8 ?, Kc89; Kc 816 and the other group of counter-contacts Kc 82, Kc 84, Kc 86, Kc 88. The different combination of c-counter-contacts compared to a- and b-counter-contacts is due to the fact that when a participant of a four-company line is selected, a certain of two ringing current sources WQ i or WQ 2 is to be applied either to the a- or to the b-wire, while if one of the two subscribers of a two-way connection is selected, the ringing current source WQ i is to be applied either to the a-wire or to the b-wire . -The first participant of the company management GL i is elected. The line selector is set to the first contact step. The mating contacts Ka 81, Kb 81 and Kc 81 are in contact contact with the bank contacts Ka 8'1, Kb 8'1, Kc 8 "-. Since the contact 15 u is closed, the ringing current source WQ i is connected to the wire GL aa via the contact pair Ka 81-Ka 8'1 and activates the alarm clock at the subscriber i of the company line GL i, but not the one tuned to a different frequency, also on the line GL i a located alarm clock at the subscriber ? - The line selector has been set to the second contact step for the purpose of calling subscriber 2 of the company line GL i. The incoming a wire is connected to the bank contact Ka 8'2 via the mating contact Kä82 and the incoming b wire is connected to the bank contact Kb 8'2 via the mating contact Kb 82. Ringing current is again applied to the wire GL ia: However, the ringing current source WQ ä is applied, because in the test and blocking circuit running via the mating contact Kc 82 and the bank contact Kc 8'2, the switching relay U is excited, which is activated by opening the contact 15 u turns off the AC power source WQ i and turns on the AC power source WQ 2. The ringing current only activates the alarm clock for subscriber 2 of company management GL i.

If the line selector is set to the third contact step, the switchover relay U is not in the test and blocking circuit, just like when the subscriber z of the company line was selected . However, this is applied to the wire GL ib, because in the third contact step the incoming a wire is connected to the wire GZ ib via the mating contact Kb 83 and the bank contact Kb 8'3, so that at the third station the arider b- The wired alarm clock is activated. # The alarm clock at participant .E of the company management is also on the b-core. It is only operated; when the AC power source WQ 2 is turned on. This is again achieved in that the relay U is switched on in the test and blocking circuit running via the mating contact Kc 84 and the alternating current source WQ 2 is switched on while the alternating current source WQ i is switched off.

For an optional call to one of the two subscribers of a two-way connection, the alternating current source WQ i is to be applied either to the a- or to the b-wire. The test relay P is therefore directly connected to the mating contacts Kc 89 and Ec 819. At contact step g, the incoming ä-wire is connected to the wire ZLa of the two-way connection line via the mating contact Ka 89, and the incoming b-wire is connected to the outgoing wire ZLb tied together. The ringing current therefore activates the subscriber's alarm clock on the a-wire = the two-way connection.

In order to be able to call subscriber 2 of the two-way connection, the incoming a-wire with the wire ZLb and the incoming b-wire with the wire ZLa is connected to the counter and bank contacts on the contact step io of the line selector. The ringing current therefore runs over the wire ZL b and activates the alarm clock of subscriber 2.

Except for the possible applications shown in the drawings of the invention, this is also for carrying out all others, only for connections certain outgoing or incoming traffic directions necessary switchovers applicable. For example, reference is made to the following possible applications: Over a few decades of the group selector, the current impulse is given in the form shown in Fig. i obviously with or without control voltage at b or partly with, partly without Control voltage. The same group dialers are used for connections over other decades To pass DC loop current surges or alternating current surges.

In the case of connections over certain decades of voters or in the case of line selectors, if necessary only for connections to certain connection lines of one or a few decades, the counting must be suppressed. A relay (like relay H in Fig. 3 or - TI in Fig. 4) is located in the access to a group of c-mating contacts, possibly only to a c-mating contact of a decade, this group then only consists of one mating contact. , which makes the counter relay Z ineffective or, arranged on the line selector, prevents the delivery of the Zaideinleitekriteriüms. Special control currents, for example via the test wire, which influence a counting suppression relay, or a special design of the connection line to a point to which the connections are free of charge, are avoided.

In the case of connections in certain traffic directions, the group division of the mating contacts, a multiple counting can also be initiated.

The selection of a free multiple connection line when setting the Line voter at first Connection of a multiple connector can be initiated without using special collective contacts.

With call seekers, the switchings that taking into account the type of calling line or class which the calling subscriber belongs to, in the call finder or in the one linked to him Voters or transmitters, e.g. B. to prevent the choice in certain traffic directions or for different counting or for influencing coin cashiers or to absorb power surges of a special kind, etc. are necessary. Also special services for subscribers to be served preferentially, if necessary only for one of the group to be served by the call seekers of a group of Participants can be initiated. Furthermore, a signal to an officer.

Are via internal, from call seekers and number surge receivers existing connection routes are given incentives for connection traffic, so can through the group-wise grouping of counter-contacts of the call seeker contact bank the Group to which the calling connection line belongs to a free, with the latter the outgoing connection line to be interconnected must be identified. is the connecting line equipped with several voters, so -will be under the influence This indicator is only left on the voter in whose contact bank the calling party Connection line is connected.
