In such a configuration, the connected call depends on what results from the circuit arrangement according to the invention, the losses in the integrated networks result in a good decoupling between the three parts. Also the connection of the warning of the _{master of} an intrusion conversation, since each subscriber suddenly speaking subscriber _only the conversation of the two remaining subscribers requires circuit symbols is supplied in amplified form with the known DT-PS; In the case of the amplifier, there is no problem with the controller, so there cannot be any feedback effects. Considerable expense. come. The amplification can also be achieved here

The object of the invention is to adapt a new type of sound to the attenuation of the system. A further processing arrangement of the type described to advantage consists in particular in that the Dämpschaffen, we before a good decoupling possibility f _ung, regardless of the phase position of the three cycles for the individual, those involved in the Aufschaltgespräch 30 _s i _c h repetitive through-connections between th Participant ensures that individual participants and the activation rate can be entered easily. the Aufschaltzeichens possible and in nearly independent Said training an adaptation of the control operations in _e i _ne four-wire through-connection is also particularly suitable for the manner by a subscriber permits in up switched calls to the at normal course of a portion of phase with a Mischsprächen. The switching amplifier to be created is to be connected and, in the other dividing arrangement, in particular a four-wire phase of the phase, should allow this subscriber a sample of a through connection of the low-frequency mixture of the two remaining subscribers involved in the intrusion call. borrowed participants from a local mixer amplifier

According to the invention, the task is thereby transmitted. It goes without saying that that solves the need for a low-frequency mixture in the individual mixed samples to be taken up from these for each subscriber of a feed-in amplifier in a simple manner the connection symbol talk on the voice bus can be mixed with an on-demand. The logic circuit set connecting and by a logic circuit ensures a suitable actuation of the amplification this switching set of controlled amplitude sample transmitters and receivers, so that the test receivers is provided, and that the pronouncements actually work in the manner described outputs of these amplitude sample receivers can be transmitted to mixed channels.

It is now assumed that the participants A <° amplitude sample transmitter APS-A and the amplitude and B are already conducting a conversation.

outputs, one of which is connected to the clock pulses of subscriber C. A and the information Au line 7'2 and the other at the output 5 and ΛΛ 'at the output of the circulating storage unit US so there is the output of a further AND gate 7 lies. To which the AND gate 7 again sends a pulse. The output of this AND gate 7 is also this pulse, which can be subject to errors, loads AND gates 8, 9, 10, each with an input to the AND-closed, controlled by the clock pulse line 72. The inputs of the AND gate 7 are gate 3 out of an error-free section and at the columns Au and KN of the Umhuifspeidn.'rs US io gives it aul that from the OR gates 1 and 2 (Fig. 1). The AND gates 8, 9, 10 are also standing flip flops. The end of the two further AND gates 11, 12, 13, 14; 15. The output pulse is assigned by the clock pulse line 16, in such a way that the training 71 determines. At the output of the flip-shop, the AND gate 10, each with one input, appears to have a pulse whose pulse start is later connected to the AND gate 15, 16. the output i ₅ is the beginning of the pulse of the AND gate 9 at each input of the ter 7 pulse and whose pulse end AND gate 13, 14 is and the output of the AND is specified by the clock pulse line. The end flank of the 11, 12 given to the flip-flops 4, 5, 6 is connected by gate 8 at each input of the AND gate. The second input of the impulse is switched on by one place-AND-gate8. 9. 10 is tet from the outputs of the _20. A second flip-flop 4 or 5 or 6 is applied to the AND gate 9. In contrast, input signals are on. this has the effect that in each case one of the second inputs of the AND gates 11, 13, gang of the AND gates 13, 14 is applied. The 15 or 12, 14, 16 combined and with the further process now takes place in the same way. as it is connected to clock pulse lines 73 and 74, respectively. The control 25 is connected to the AND gates 11-16 outputs already described above.

In contrast to the gates 8, 9, 10 and also to the one input of the circuit arrangement according to FIG. 3 are the AND gates 3 are there At the AND gate 8 there are 50 AND gates 12, 14, 16 with their outputs on a pulse at both inputs, so that the common OR gate is given, which the Am- AND gate 8 turns on and each controls a one-plitude sample transmitter APSS. The arrangement of the AND gates 11 and 12 is applied. According to FIG. 4 has compared to that according to FIG. 3 the before the duration of the output pulse of the AND part that it only requires an amplitude sample transmitter beGatters 8 comes first of the clock pulse line Γ3 55; However, it cannot be used for all purposes and can then be used by the clock pulse line Γ 4 because the speaker hears his own language as a result of the mixed pulse on the AND gates 11, 13, 15 or 12, 14, and somi 16. It thus first switches the AND gate 11 and undesired feedback effects not then the AND gate 12 through. This closes the amplitude sample receiver APE-4 and the connected 60
