PATENT OFFICE.

The subject of the main patent is a circuit arrangement for telephone systems with dialers for making connections, for special ones, for making connections Occurring switching measures (e.g. call counting if the tariff is different, etc.) special workplaces are provided.

The invention now relates to a further embodiment of this arrangement in such a way that "that also facilities at the offices provided for the special switching measures for monitoring established connections, as well as those provided, of which if necessary (e.g. at the instigation of a participant) also the separation of the bond is dependent.

With the invention, an increase in the operational safety and operational readiness of the Plants intended. By constantly monitoring the connections made using the switching devices at the special office places will be the detection of malfunctions of any kind immediately after their occurrence and enables them to be eliminated as quickly as possible. Such disturbances can be caused by inattentive operation on the part of the officers in semi-automatically operated telephone systems, by harassment on the part of maliciously calling participants, by failure to come about caused by connections due to the absence of required participants, etc.

There are already devices for detecting such malfunctions in a semi-automatic manner operated telephone systems are proposed, but these facilities are provided at each of the payor's offices. As a result, everyone has to come from the calling party and everyone to the requested one Subscriber outgoing connection line each be assigned a monitoring signal device individually. Also takes place in these known devices the separation of the connection is not automatic, but it must be brought about by the civil servant. This has the further disadvantage that learning the civil servants in the relevant places is more difficult because they attract their attention not just a few simple steps in the establishment of connections, but a whole series of manipulations have to judge.

These disadvantages are eliminated by the invention, and it is also made possible that in the event of a malfunction that causes the intervention of a surveillance officer required makes, the switching elements for the release of the connection are influenced in such a way, that the release of a connection

instead of the participants by the security officer is dependent.

The number of connections to be monitored by an officer at one office can be a relatively large one. It can e.g. B. a civil servant a field of 500 pairs small incandescent lamps, such as those used in telephone exchanges, are easily overlooked, and operating the switching devices (pushbuttons) to release the connections also takes little time. Therefore, the officer can also relatively seldom occurring messages, e.g. B. regarding malicious interference. Therefor can serve the monitoring or final signal lamps, which z. B. by Repeated short-term interruptions of the line loop at the station (short repeated Pressing down the hook switch) can be made to flicker. The monitoring signals and the triggering devices can be connected to the connections and the influence either at the time of establishment or after completion of the establishment be subordinated to the participant office. This is done by the automatic, the connecting devices or groups of these devices associated switching devices causes which in the latter case upon termination the establishment or when the connection is established (after setting of the line selector when reporting the called subscriber) previously under the influence of the calling or the setting the electoral agency to switch triggering organs, and the Assume the influence of the monitoring station. At the same time, the closing signs are also used or monitoring signals are automatically switched on to the existing connection so that they can be influenced by the interconnected participants.

Are the monitoring and tripping devices groups of connection devices assigned jointly, they can be connected automatically using the service selector take place. Furthermore, the number of signaling devices and switching devices to release the connections

go a civil servant will still be reduced by that these devices only connect to the voice connections during or after the call has ended be switched on.

Such an arrangement is also useful in which the relevant signal devices together with the associated switching devices for triggering the connections by officers at the point of connection be turned on at which those Switching elements are arranged united, the 'making the connection under the Influence of the calling or the setting of the voters and after completed connection are under the influence of both participants in the connection. Therefore the signaling devices, e.g. B. in telephone systems, without a surge transformer in the office at the line selectors, but in systems with impulse transmitters at these arranged. This avoids special switching devices that are involved in manufacture the connection, the relevant signaling and triggering devices to the one, and after the connection has been established possibly at another point of the connection, or if left switched on connect the first point to a second point of the connection.

For systems in which the release officers are only supposed to receive reports; which refer to disturbances after a speech connection has been established, it is It is advisable to enable the monitoring devices to be switched on and the connection to be released only when also the called subscriber of the connection has given the final signal.

In order to enable the trigger signal and switching devices to be connected to the connection to be able to effect even if the calling subscriber has dropped his receiver lets to thereby z. B. maliciously blocking the called line, the connection can can also be brought about by a special switching measure at the called station, e.g. by repeated short-term Press down the hook switch or lift the finger disc at the called station. It will then at the same time also a special signaling device at the release officer or else in a special one Way the final signaling device assigned to the relevant subscriber (Flickering of the tail lamp) brought into effect. This allows the release officer determine the number of a maliciously calling, harassing subscriber or even if the listener is not attached maliciously calling subscriber a blocking of the subscriber called by this impede.

Several embodiments of the invention are shown in the drawings.

In the circuit arrangement shown in FIG. 1, the connection can be established automatically or semi-automatically (via service selector DW) . The release of the connection is placed under the influence of a release officer or an official position from the beginning of the establishment with the group switch gs switched on. This office station is connected to the connection using

of the service voter SDW. If the calling subscriber Ta hangs on his receiver before the requested subscriber reports and consequently before the bridge relay 5 "is excited, both tail lamps SL light up, one of which, SL ₁ , belongs to the called subscriber Tv : this signal calls the officer on causes the monitoring station to disconnect the connection.

ίο If the called subscriber Tv has _{reported, the tail lamp 5X 1} from the calling subscriber Ta, the tail lamp SL ₂ through the excitation of the relay S and thus the relay VS via earth, battery, k ₁₃ Vs, is even if a call does not take place 13, earth depends on the called party. The connection is only released in this case when both tail lamps light up. The effect of this circuit arrangement is as follows:

If the calling subscriber Ta has suspended its listeners, then the group selector GW by contact 12 whose membership is indicated b to line relay B by the index, the relay Vb to ground, battery, Vb, 11, 12, energized earth. This relay remains energized until the relay .9 responds when the requested participant Tv reports. The relay 5 ″ then switches on, as mentioned, a delay relay VS via earth, battery, Ii _{11 -Vs 3} 13, earth, which switches itself on via 14 in a holding circuit and switches off the delay relay Vb at 11. When the group selector GW the relay Vb responds, so a starting relay An is excited via earth, battery, An, gs _s , F ₁ 15, earth, which brings the service selector SDW to the connection or the calling line for setting.

If the calling subscriber hangs up his receiver after the called subscriber Tv has reported, the de-energization of relay A via earth, battery, SR ₁ , 1, AT ₁ , gs ₁₃ 2, 3, 4, earth that takes place Relay SR ₁ energized, which is connected to earth, bat-. terie, 21, 5 "L ₁ , earth the tail lamp 5" L ₁ turns on. Now also depends on the called party Tv its receiver, so the relay Y and the relay 5 is de-energized "and to ground, battery, SR _2, 5, AT _2, GS _2, 6, 8, 10, ground the end character relay SR ₂ turned on, which turns on. As a result, the trigger officer is caused to carry out the separation of the connection, which is effected by pressing the MT key to ground, battery, 22, 5X _2, soil the final lamp SL _2. Here, above ground, battery, MT ₂ , gs4, M ₁ Iz ₂ , earth the tripping magnet M is energized, which turns on via 19 in a holding circuit.

In order to automatically separate the connection, the excitation of the release magnet M can be activated by flipping the switch gs, e.g. B. from the called subscriber side, take place. In this case, when the connection is made, the release service station is not switched on, and the release magnet M is excited when the handset is attached to the called subscriber station via earth, battery, 17, 18, gs ₄₁ M ₁ k ₂₁ earth.

In order to establish a connection between the calling or called subscriber Ta or Tv and the release officer before or after a connection has been established. enable is made possible by repeated brief line interruptions at the station, e.g. B. on the hook switch or by dial lift, either one or both tail lamps SL ₁ , SL ₂ to flicker. This signal causes the release officer to press the buttons AT , so that the intercom is connected to the connection via AT ₁ and AT ₂ , while the resistance w in the circuit of the test relay T of the service selector SDW is short-circuited by the button AT _S so that now about earth, battery. MT ₁ , AT 3, 20, T, gs _s , F ₁ 16, earth the relay F is energized, which at its contacts 2 and 6 causes the interconnection of the speech wires leading to the office station. The officer can release the connection blocked from any side by pressing the MT button.

In the illustrated in Fig. 2 circuit arrangement of the connection of a triggering service space over einenDienstwähler5'i) ii ^/ only at the register of the called subscriber and energizing the feeding bridge relay Y. This relay causes to ground, battery, X, 23, 27, earth energization of a carried Relay X, which switches on via 28 in a holding circuit. Relay X - causes a starter relay An to be excited via earth, battery, An, 29, 24, earth , which brings the service selector SDW to the established call connection for setting by connecting earth, battery, 42, R ₁ 43, earth, and thereby causes the excitation of the rotary magnet D via 44, D _{1 45, interrupter, earth.} Once the setting has been made, the relays P and T respond via earth, battery, 33, P, T ₃ 24, earth, of which relay P short-circuits its high-resistance winding at 34 and relay R and the rotary magnet at 43 and 45 D turns off. The relay T switches off the starting relay An at 29.

If the calling subscriber Ta attaches his handset, the relays A and B are de-energized; this also interrupts the circuit of relay Vb at 25 and 26, respectively. The de-energization of the relay Vb \ v is over earth,

46, 40, 36) SL ₁ , battery, earth brought the tail lamp 5 "L ₁ to light up. If the called subscriber Tv picks up his receiver, relay Y is de-energized and via earth, battery, SL ₂ , 37, 38, 39, earth, the tail lamp SL _{2 is} switched on so that both lamps are now on, causing the release officer to release the connection by pressing the buttons MT.

The tripping magnet M is excited via earth, battery, MT ₁ , 35, 48, gs ₂ , M, k _x , which triggers the line selector. At the same time, the circuit for the relays T and P is interrupted by the MT ₂ key, so that the service selector SDW and the office station are released.

The circuit diagram according to FIG. 3 shows an arrangement in which the connection of a release service station via the service selector SDW only takes place after the call is terminated when the receiver is attached to both interconnected subscriber stations. This circuit arrangement works as follows:

When reporting the requested participant Tv , a relay E is excited by the excitation of the relay Y via earth, battery, 52, E, 53, 54, earth, which keeps the circuit of the release magnet M interrupted at 72. If both participants hang up their receiver, the relay Y is deenergized from the called participant side and Vb from the calling participant side. As a result, a relay F is excited via earth, battery, F ₁ 56, 57, 58, 59, earth, which switches on at 60 in a holding circuit. This relay F switches off relay E on the one hand at 52 and on the other hand via earth, battery, An, gs _s , 63, earth the starting relay An on . By energizing the relay R via earth, battery, 64, R, 65, earth and thus via 66, D, 67, breaker, earth, this excites the rotary magnet D, which brings the setting of the service voter SDW to the established connection. Once this has been done, the relay T responds via earth, battery, 68, T, gs _z , 63, earth, which short-circuits its high-resistance winding via 69 and at 61 via earth, battery, SL, 61, gs _x , 62, Earth brings the tail lamp SL to light up. By pressing the MT button, on the one hand , the tripping magnet M is excited via earth, battery, MT ₁ , 70, gs ₂ , 73, 74, M, Iz ₄ , earth, which triggers the line selector, and, on the other hand, via button MT ₂ by de-excitation of the relay T, the release station is released.
