DE2635032A1 - Control circuit for telephone exchanges - has centrally produced pulses common to central controller and controlled elements - Google Patents

Abstract

The control circuit for telephone exchange is designed to reduce the technical complexity of dialling pulse selection circuits using a large number of lines for marking. The control unit and the individual elements being controlled are associated with the same in-phase impulses produced from a central source. The controlling unit has a comparator which activates switches if the registered criteria for selection are the same as the number of dialling pulses received from the pulse generator. The controller has circuits which carry out the connecting through of the continuous pulses and time identification signals via a connecting line to the controlled unit.

Description

Circuit arrangement for the control of

Switching systems.

The present invention relates to a circuit arrangement for controlling switching systems. Circuit arrangements of this type are already known. In such a known arrangement, a connecting wire had to be provided for the control, via which the identifier marked by the number of pulses was then transmitted. The relays receiving the pulses had to be precisely adjusted so that there were no distortions The marking was carried out by combining the assignments of cores 0 Here, a great deal of technical circuitry was required for the evaluation.

The present invention avoids the disadvantages of these known arrangements in that a controlling element (e.g. Io, central control device) and the respectively to be controlled development level the same respectively. In-phase, centrally generated continuous pulses are assigned and that a comparison arrangement is provided in the controlling member is, the switching means can come into effect if the respective stored selection criterion is equal to a number of dialing pulses assigned to this criterion, or combinations of numbers of dialing pulses that are picked up by the continuous pulse generator 0 For the connection of the continuous pulses are provided in the controlling element switching means that make the connection if necessary and at the same time a time slot identifier Send via a connecting wire to the advanced stage to be controlled, in the switching means are provided that come into effect through this indicator and also the A Put continuous impulses to individual switching means that utilize the impulses 0 If equivalent Pulse number of applied continuous pulses and the stored criterion come switching means on the effect that disconnects the continuous pulses and a time slot indicator to the G advanced level to be controlled, in which the switching means come into effect and cause the continuous pulses to be switched off.

The invention will now be explained in more detail with reference to the drawings. In Fig.1, the AS is powered. only the switching operations are explained that is necessary to understand the invention, if a subscriber T1n picks up, the AS adjusts to him. The AS is supplied with power. A free central device is now connected to the AS / I.GW via the relay search selector RSW. With pulse selection, the switching processes are as follows: The pulses are recorded in the criteria evaluator KAW and in the selector setting WE switching means are set to one or more timing pulses according to the pulses. The control of the voters takes place on the basis of timing pulses, this will be described later in particular.

When dialing keys, for example on a tone frequency basis, takes place in the KAW an evaluation and in the WE a setting for appropriate timing pulses. If the voters are, for example, motor voters, the selection criteria must be stored required, from the KAW the selection criteria are given in the memory Sp and then only in the WE. The number of memory units depends on the circuit of the rotary selector away. With 56 steps, a time requirement of, for example, 350 ms is required, In such a case, there is enough memory for 8 key figures, because yes during the setting Memory become free again. There are none at all for switch matrix voters Memory required. If, for example, the I.GW reaches a remote dialing transmission, so in the WE there is a changeover to tone frequency selection. The changeover criterion can can either be determined from the key figure, or by means of a return indicator via a controller. The same is required for some local connection cables. It is advantageous when reaching the LW, if this corresponds to the present one Invention is controlled, given a return mark. This ensures that this can be set to the selected one step in one turning process.

As already mentioned, the RSW is started via 3c, 4ch. If a central unit ZE is free, it is switched on via the RSW to the AS / I ##. GW0 In the ZE, a timing pulse is then switched on via 34ch, which also in the AS / I.GW with the opposite potential on the relay winding CH lies. CH relay responds now and remains in this position after the end of this pulse because it is a bistable relay. 4ch opens the event circle. In the KAW criteria evaluation, the i-wire of the RSW placed the dialing character, which is then sent to the subscriber via the OLÜ. The dialing impulses are picked up with the relay A and given to the KAW with the 5a contact.

As already described; voter control is based on time namely in such a way that the election criterion and that assigned to this election criterion Exit, resp. Output group timing pulses of the same phase are assigned. In the selector setting then uses the timing pulses coming from the selector via the d-wire compared with those determined by the election impulses and in the case of coincidence the voter shut down. In the WE are switching means that are triggered by the dialing pulses can be set and the corresponding timing pulses are connected to their outputs are. If the first series of dialing pulses has been completely saved in the WE, it takes place starting the motor by closing contact 33x in the ZE. By the timing pulse at this contact is brought into the AS / I.GW by relay X, a bistable relay.

The engine is started with 12x. Did the voter get through the election impulses If the specified output is reached, there is coincidence. Switching means come in the WE to the effect that subsequently apply earth potential to the c-wire of the RSW. Both windings of the motor selector are energized and thereby shut down the voter. A timing pulse is sent to the AS / I.GW via 31p in the ZE, which controls the P relay brings to suit. Before this pulse, a timing pulse is applied to contact 40xI applied, which brings the X relay into the starting position via winding XI in As / I.GW. 12x opens the running circuit of the motor. As a result, the potential is then in the WE removed from the c-core / RSW. 13p opens the shutdown circuit.

11p brings the pressure magnet that switches through the a / b wires.

- With the first series of dialing impulses, the dialing signal was switched off from the iä wire / RSW. 15cg opens the marking circuit. The output marking timing pulses are thus switched off and the second GW is marked as occupied. 25cg switches the d-wire through to the following selector. If the next series of dialing pulses has been saved, the 36xg contact is closed in the ZE and brought into the II.GW XG relay. The impulse is transmitted via the @@ wire. 18xg leaves the voter on. In the following LW the output marking is above the 15cl contact (Fig. 10). If the output determined by the dialing pulses is free, then there is again coincidence. In the WE, earth potential is again applied to wire o of the RSW, which energizes both motor windings via 19xg. As a result, the motor is stopped on this output. A timing pulse is then switched on again in the ZE via a contact (not shown), which causes the ## - XGI winding to come into effect in the II.GW and brings the XC relay back to its starting position. 18xg switches off the running circuit of the motor and 19xg the shutdown circuit. The identification that the next voter is an LW is marked by the JL timing pulse, which is switched on in the LW and is fed to the ZE via the 3dl1 and the a-wires of the selector. In this the JL relay responds to which there is also a timing pulse of the same phase. The JL relay ensures that the LW is only set after the series of tens and single pulses has been stored and, if necessary, switches the evaluation device in the WE accordingly. With the shutdown of the engine in the 2nd GW, the CL relay was brought into the LW at the same time, so that the transmission wire d switches to the output of the LW in preparation for the output marking. If the tens and singles pulses are stored, the ZE 39x1 contact is closed, to which such a timing pulse is applied, which is in phase with the timing pulse of the XL relay in the LW. As a result, the XL relay is now brought into the working position. The impulse is transmitted via the a-wire of the voter. The engine is now started via 5xl. 16xl switches the output marking pulses via the s - @ d wire to the WE in the ZE. If there is again a coincidence between the timing pulse determined by the pulses and the one switched on at output d of the LW, a switching means is brought into the WE that applies ground potential to the c-wire of the RSW. ## Both motor windings are then energized via the c-arms of the voters and the 25xl contact in the LW. The voter is shut down. In the ZE, the 41x1I contact is then closed, to which a timing pulse is applied, which in the LW via the XLI winding brings the relay XL back to its starting position0 5xl opens the running circuit and 25xl the shutdown circuit of the selector. As a result, the PL relay in the LW is now brought via 42pl in the ZE ... 17pl continues to hold the CN relay in the subscriber circuit.

In this case, the XL relay is only activated after the PL relay has entered the Working position was brought to the starting position. If the CN relay is a bistable Relay, counter potential must be applied when tripping. 26pl brings the pressure magnet to suit. 7pl and 8pl apply supply voltage to the speech wires. About the contact 43ml in the ZE a timing pulse is now applied, which brings the M relay in the LW ## gt. 6m contact switches ringing current to the subscriber loop. After approx.

1000 ms, a timing pulse is given to the LW via 44mII, the Brings relay M back into its starting position via winding MI. 6m switches the ringing current from the subscriber loop. The call forwarding is done in the same way controlled. If the called subscriber answers during the call, the A relay speaks via the participant loop. Another reverse winding of the M relay comes through 21a namely MII.

This brings the M relay back to its original position.

6m removes the ringing current from each voice line. If the called subscriber answers during the call pause, relay A also comes over the subscriber loop. The circuit via the 21a contact has no effect, as the M relay was already in its initial position. The 9a contact switches the voice wires through # and removes the short circuit of the AI winding. 22a gives a timing pulse via 3dl1 and the a-Der to the ZE, in which the ZZ relay is brought, which is also connected to a timing pulse in the same phase. The ZL relay in the LW can now either be brought via 21a or via a timing pulse from the ZE (not shown). The 28zl contact applies voltage to the b-wire via the choke DrII winding and the contact 27zl for symmetry the choke DrI-Vicklung via a capacitor to the ##### wire. Before the ZE is now activated, the control must be switched from the a-wire to the d-wire, which is no longer needed for disabling the selector. Control, ie shutting down the selector via the a-wire, is not advisable for the larger currents required. It only works if there is an electronic control system for each voter, one from the ZE Gets a stop pulse. Such an arrangement is shown in Fig. 2 - A pulse of the same phase can be provided to control the ZG relay in the I.GW, the BG relay in the II.GW and the DH relay in the LW. 14zg, 17bg in Fig. 1 and 2dh in Fig. 10 switch the control relays to the ed wire. As a result, the relay ZH in the I.GW, BGH in the II.GW and DL in the LW (Fig. 10) is controlled with the contact 32zh in the ## ZE, at which there is a timing pulse. The contacts 9zh, 10zh in the I.GW, 16bgh in the II.GW and 3dl1 in the LW (Fig. 10) disconnect the control relay from the a-ADER. 1dl1 switches through the speech vein a in the LW. The calling subscriber is now connected to the called party.

The central facility ZE is now activated.

If, for example, a remote dialing transmission was switched on instead of the 2nd GW, a timing pulse was sent from this to the ZE via the control unit. After evaluating the same in the ZE, a timing pulse ZH1 relay brought to the I.GW (not shown). 8zh1-Kontkat switches earth to the Z-relay, so that a count is guaranteed during the call. A decade mark is not required, i.e. long-distance traffic can optionally take place over any decade be flexed, for example via the 1st and 0.

The occupancy of an output of a voter can, for example be done by timing. It takes a motor selector to overrun 112 steps approx. 800 ms. If the respective voter has not found a free exit after this time, so, as already described, it is stopped. From the KAW is then over the i-wire and the OLÜ winding sent the busy signal to the calling subscriber.

If the calling subscriber hangs up, the relay drops and as a result C relay (not shown) in the I.GW. There is no longer any potential on the i-wire. As a result, the central facility is switched off. Everyone is in the I.GW Trigger timing pulses led to the ZI point. When i tripping, a predetermined The timing of the switching operations is guaranteed so that the control wire that Yes may go over several electoral levels, is only activated when in every voter all relays were brought to the starting position and always from the last selection level from started, ########################### or possibly

simultaneously. In the present case, each LW is triggered when the calling subscriber hangs up, i.e. regardless of whether the called subscriber has hung up. Only when the output marker pulses are on the d-wire again, the respective selector is released again. The d-wire is interrupted by contacts ## ad of the pressure magnet, as a result of which the pressure magnet must be the last switching means to drop out and of course the relay that controls the pressure magnet. Instead of the contact of the pressure magnet, a relay can also be provided. When triggered, the following time position pulses come in sequence in the present case: 1. LW Fig. 10 MI, ZLI, XLI, CLI, I.GW Fig. 1 ZHI1 (ni ## cht drawn) = 1st timing pulse 2nd LW, DLI (not drawn), II.GW (Fig. 1), BGHI (not drawn), I.GW, ZRI = 20 timing pulse 3rd LW DHI (not shown), PLI, II0GW, PGI, CGI, BGT, ## I.GW, PI, CHI, ZGI = 3rd pulse Since the principle of the triggering process in Fig .5 is shown, the individual switching operations, which are known by existing voters, are not specified as precisely. For this reason, various relay windings are not shown or mentioned at all. Because the circuit operations are so simple, the circuit is perfectly clear to those skilled in the art.

In order to get a timely use, a trigger timing pulse is required provided, with which the off relay is then brought on via 22c, 2ch0 Via The three trigger impulses listed above are then successively generated in time which then one after the other the relays listed under 1, 2 and 3 in the Bring the starting position. The PL, PG and P relays in the three options now give the Contact magnets free Your ad contacts then switch the output marking impulses again to the d-veins. At the same time, the a / b arms of the voters are separated. The voters are then ready for occupancy again.

The ZE can of course also trigger it until it is reported. If the ZE is switched off immediately if it is triggered during the setting, must be guaranteed that the respective voter in any case before the triggering is stopped. This can be achieved once, for example by using the Drop-out time of the C relay in the I.GW to 120 to 150 ms and that in the central facility ZE is set to 90 to 120 ms, or to the i-wire of the RSW a high-resistance winding C is placed, which causes the relay C to drop accordingly delayed. So that the C-relay winding in Fig. 1, IoGg has no influence on the impulse generation has, one is in the central device for the relay receiving the pulses Counter winding provided so that the current through the relay does not affect the Has impulse. There are of course other options with auxiliary relays.

When dialing a button, the a / b wires are switched through directly to the ZE0 In Fig.5, the basic circuit of the triggering of the three selection levels is shown. In this example, this takes place in the direction of the connection establishment. Just like that of course, a reverse release from the LW depending on the called subscriber The OFF relay is then arranged in the LW. During the operating state can of course # transmit criteria on a time-based basis via these control lines according to the principle at the time of triggering. An activation of the Counting voltage and the bottle mark is also not required. A starting sign can, for example, also up to the I.GW or the last incoming remote dialing transmission be transmitted. The final character can also be used up to the last incoming remote dialing transmission or equivalent transfer, so that the LW untransferable can be made even cheaper.

In Fig. 7 the marking of the decades of the group selector is shown. The outputs of arm d (Fig. 46) are always the same at each output of each group Decade pulse switched on, e.g. dk1. When setting group dialers, then in the ZE Fig.6, for example, the relay selector dM corresponding to the dialing pulses set. The relay selector dM for marking the single pulses is here not required and therefore switched on via the initial potential, since the Evaluation is carried out after each circuit. Lies while the motor selector is running the same decade pulse (in phase) at an output as at the dM magnet, so becomes the electronic link opened. The PZE relay in Fig. 6 responds and switches with its contact pze potential to both windings of the motor. The engine will thus shut down. A bistable electronic circuit arrangement is expedient used that after termination the shutdown again in the Starting position is brought. You can also use the control potential at point P Apply electronics to point S until shutdown is complete. To avoid this of double tests, the decade pulse in the ZE is divided into ZE1,2, .. pulses, i.e. there are as many ZE pulses as there are ZE devices in each decade pulse are. In this way it is possible to block the remaining ZEs immediately, by applying a corresponding potential to S of the same. If an LW is to be set, the timing pulse L (Fig.iO) is sent from this. In the ZE this becomes evaluated (Fig. 1, JL relay). dM and eM relay selectors are selected according to the tens and one pulse set, namely the dM selector to a decade pulse such as it is shown in Fig. +8, and the eM selector on a single pulse such as such are shown in Fig.8. At the voter arm d there are then single pulses corresponding to the Number of outputs Does the one on the d-arm match the 3-decade and burner impulse in the ZE, the electronic device is opened again (Fig. 6, PPZE relay ## speak and apply potential to both with its pze contact Motor windings of the LW. In order to avoid double checking, as already described, the timing pulses at the eM are again subdivided into the number of ZEs.

In order to keep the shutdown current for the selector small, an arrangement according to FIG. 3 can also be provided. in the Silence * s set circuit is switched on via 3x a series resistor Wi and parallel to it a relay H, which can be a bistable relay. During the shutdown, the motor windings are energized, which creates a braking effect. The shutdown process is only initiated with 1h when the H relay responds. The marker arm d can also be switched slightly leading.

The timing pulses for controlling the relays in the advanced stages are much longer in terms of time. A bistable relay has a pick-up time of approx. 3 ms. As a result, a timing pulse must be at least 5 ms. The break can be shorter. In Figure 4 timing pulses are shown, but for the Control of voters not entirely complete. The off timing pulse brings in ## I.GW the off relay, which then the Trigger pulses 1,2,3 to the control wire switches. At the point BZL Ausl. In the IoGW, only the trigger pulses are switched on0 In Fig.9 another arrangement is shown in which only one relay winding is required is to switch the relay controlled with timing pulses to work and again to bring into the starting position by reversing the current and reversing the decoupling members. If monostable relays, e.g. ESE relays, are used in this arrangement, then one winding for the suit and for shedding, and the other winding for keeping is provided. Before the ZE is switched off, another relay is activated VIL also brought about a timing pulse, which is then a relay U brings that makes the switch. You can also control the U relay directly, if it is placed in front of the underground contact.

In Fig.18 the control relays of the LW shown in Fig.10 are shown, namely monostable relays, eg ESK relays. XL relay is brought by a timing pulse and then holds on via its contact 3x1 and its winding XLI. The other relays are also activated with timing pulses and held by their own contacts and a second winding. However, since the relay XL controls the running and the shutdown of the motor selector, it must be individually brought back to its starting position at any time. With 2xla the holding circuit of the XL relay is then opened if necessary, so that the XL relay switches back to the initial position, As shown in Fig. 2.3 after the off-impulse. Accordingly, in Fig. 18, all holding circuits of these groups can also be routed via a contact of a relay, which is brought with a timing pulse 1, 2 or 3 and the corresponding group with its contact by opening the holding circuits can come to waste. If, for example, group 1 is to fall, the relay AU1 is brought. The contact laul then opens the holding circuits of group 1. The same is done by relays AU2 and AU3. The contacts 8au2 and 1Oau3 then open the corresponding holding circuits. In a circuit according to FIG. 9, the ejection relays AU1 to AU3 not necessary because the pull-in winding is also connected as a drop-out winding. However, an XLA relay is necessary, for example, since the IL relay must be brought into its starting position at any time.

Line voters sometimes require that they be busy Output to be shut down on this. In the circuit arrangements described so far, for example in Fig.

10, the output marker pulse was triggered by a contact of the 35-occupancy relay, in Fig.10, 20cn, disconnected. A circuit arrangement is now shown in FIG. in which the output marker pulse remains on and the voter as a result is also stopped on the occupied exit. For this purpose are about one Arm of the selector, in the example c-arm, two timing pulse circuits switched. After the shutdown process, a relay P is activated in the LW via the control timing circuit brought. lp-Eontakt now closes a timing circuit via the c-arm and 3cn, the PD relay pulls in if the subscriber circuit is not in use, so that now derRaf and the following switching processes can be handled in the LW the 2pd contact is now closed to the second timing circuit. About this can now respond to the CN relay in the subscriber circuit. 3cn switches the test timing pulse so that another LW can no longer check this output. When busy The PD relay cannot be activated at the output, but others can be used in the LW Switching means are brought, for example, an intrusion on an occupied Enable participants.

In FIG. 13, the circuit arrangement of FIG. 12 is expanded, namely to make individual authorization markings on the same arm. For example a subscriber can use a code to reveal to the ZE that he has not called wants to become.

The key figure is evaluated in the ZE and via the control wire in the LW brought a relay NS based on timing (not shown). Of the participants has to dial his own phone number in addition to the code, for example. There the participant calls himself, the test timing pulse is switched off with 3cn, so that the PD relay cannot respond. However, 4ns closes a timing pulse circuit, via which the ESE relay then comes in the subscriber circuit. 5nsn contact switches the test timing pulse away to with subsequent callers To mark subscribers as busy0 over the working side of this contact it if at the same time a timing pulse nsr is applied 0 now the so marked Called subscriber, then speaks after shutting down the voter via the nsr timing pulse the relay NSR in the LW, which has a contact with a corresponding indicator for the ZE 22a in Fig. 10 there. The calling subscriber then receives an acoustic signal from the ZE Announcement. If the subscriber wants to delete this authorization again, he enters the PR a code, if necessary with its own phone number. The ZE becomes the LW given a timing pulse that brings an ESA relay in this. With 6nsa becomes a ZeitlageispulssFtromkreis closed over the c-arm in which the NSNI winding is located. This is energized by this timing pulse, which causes the NSN relay again is brought into the starting position0 It was assumed that it is a bistable Relay acts. A large number of such authorizations can be marked in this way werden0 If necessary, the NSN relay can also send a corresponding Give the timing pulse to the ZE via the d-wire. Further switching operations are then carried out in this initiated after evaluating this indicator.

In the case of a very large star, the same can be done with the help of a central one Arrangement happen that, for example, be designed similar to a tymwerter FIG. 14 shows a circuit arrangement in which double checking from the line selector LW of the same group thereby g is prevented that each LW another test and occupancy timing pulse is assigned. The basic one Function is the same as explained in the description of FIG For example, the 1 LW side is the test timing pulse for a group of 10 LW J1 to J10 and the occupancy timing pulses Jn1 to Jn10. In the subscriber circuit are per participant respectively. Output of the LW via @ the 7cn contact the timing pulses #### J1 to J10 (Prüfstromkrets) and on the occupancy circuit, i.e. on the CN relay Timing pulses Jnl to Jn10.

The timing of the impulses can be seen in Fig. 17.

In the device ZE Fig. 1 is a in the present arrangement It is not necessary to block the remaining ZE.

If this arrangement is dispensed with in order to avoid double checking, so a second checking LW may have to overflow again in Fig. 16 a circuit arrangement is shown in which the respective voter from the number the steps that the voter runs in the form of impulses to the central facility ZE is given, m2-Kontakt is a voter contact, for example with everyone 2nd step is actuated. There is an electronic counter in the ZE, which is exactly one Overflow marked and then the selector, for example, the group selector stops. ## After the test relay has responded, this is a pulse circuit, i.e. when testing of the selector to a free output, interrupted by the contact pg. The counter in the ZE only comes when the exits are occupied, for example one GW, to the effect. If the voter has found a free exit, the control of the test relay, for example in Fig. 1 PG relay in the IIoGW also the counting element again brought into the starting position.

Since all dialing systems are tuned to decadal control, can not all outputs, for example, of a 112-part voter with the ones and This can of course be offset by hunt groups It is not advisable to equip the telephone with more digits by using key dials. Of course, by choosing a third LW code, you can have a more than one hundred part Adjust EV. This can be done, for example, by a. Marked by the ten digit take place. If you choose 1 as the decimal number, the third LW code must be added to get voted. In Fig. 15 the marking of the 3 code digits is in the central Device shown in FIG. 6. So it's another relay selector required, which then takes up the 3rd digit. This is also to the AND or. OR control connected. Is the third relay selector, it can of course also being an electronic counting element is not necessary, there is such a potential at the initial position that an evaluation of the 1st and 2nd code numbers will take place can (tens and binary codes).

There are many conversion options, for example, you can choose three-digit LW codes from .100 to 199 and from 200 to 212. With pulse dialing, it is only wedge-wise Low 3-digit numbers should be selected. Of course, 224-part LWs can also be used on a case-by-case basis. This depends above all on the speed at which the selector is set.

There must also be no waiting times. The busy criterion can also over the d-arm, i.e. over the same arm over the exit marker is given, are sent0 The occupancy switching means CN in FIG with its contact a criterion ## to the d-wire0 it is expedient for each output create a special busy time criterion, for example like it is shown in FIG. Between the individual output timing pulses e1, e2 etc. ' are then the busy time position pulses eb1, eb2, etc. In ### the central Evaluation device ZE is then an evaluation EE for the free pulses and an evaluation EEB for the busy pulses. Both can only take effect if in each case just now the respective timing pulse series is available, at EE the pulses e1, e2, etc., at EEB the pulses ebl, eb2, etc. The switching means eM for marking the single-choice criteria must then also have the busy pulses, e.g. eI, ebl, e11, ebIi etc. The exit marker at the LW can also remain. In this way, an authorization marking respectively Markings according to Fig. 13 are made.

11 several timing pulses are then contained in the eb pulse of FIG and in FIG. 6 then a corresponding number of evaluations EEB.

In the previous circuit arrangements, the ZE in FIG. 1 was switched on at the respective connection until the called subscriber reported. In telephone switching systems, the time from the 1st call to the reporting of the two subscribers called corresponds almost to the time of the criteria given by the calling subscriber and the setting of the UiählerO The number of central facilities required naturally depends on the occupancy time of the individual facility. If the further call, uOU. Even the 1st call in the LW is initiated with the help of a central onward call circuit, the number of ZEs can be significantly reduced0 Such a circuit arrangement is shown in FIG explained, therefore d in Fig. 19 shows only the switching processes ### which relate to the 1st call and the next call, the 1st call is marked with the relay Au. Relay M is brought by a timing pulse from the ZE, via the contact 2m and the winding MI it continues, 6m switches the capacitor C, which is charged, to the relay ML. This responds via the discharge current and then drops again after the time that the Length of the 1st call is assigned 0 The discharge circuit is dimensioned accordingly. With 7ml the 1o call is sent to the called subscriber. At the same time, 5m-Eontakt has placed the relay winding MLI on the central further call arrangement, so that the ML relay now comes into play in the rhythm of the further call and also sends the further call to the called subscriber with 7ml. When the called subscriber reports, a relay (Fig. 10) is brought via the floating current loop. 3a contact opens the holding circuit of the MI relay, which drops out and opens the ringing circuits at 6m and 5m. The further switching operations have already been explained in detail in the description of FIG.

In Fig.20 a further arrangement is shown in which the 1st call is still controlled by the ZE. A timing pulse brings relay M again lasts over 3m and its winding MI. 6m contact applies ringing current to the subscriber wires.

The duration of the 1st call is also determined in the ZE. The end of the 1st call is also controlled by a timing pulse that is generated in the LW Relay ML brings. 2ml sets the further call WR to the MI winding, so that the M-relay continues to be brought to the rhythm of the further call. ML Relay'lt further via a holding circuit depending on an E contact of the A relay. The holding circuit is similar to that in Fig.

19 for the MI holding winding, which is why it is not shown. Reports the called subscriber receives the relay via the subscriber loop (Fig. 10) to suit. 4a contact ## opens the holding circuit for the MI winding and another a-contact the holding circuit # for the ML relay. The other switching operations are the same as already explained in the rewriting of FIG. 10 In long-distance traffic the central device ZE (Fig.1) would be on the connection until the start pulse stay on. To avoid this, the ZIG / Vz or an equivalent body passed on to the final office. Using the example of an alternating current transmission this should be explained in more detail for counting. In Pigo23 there is a section of a such transmission for outgoing traffic. So far the mode of action was the following: When the called subscriber reported, the ZIG received an alternating current start pulse sent. In the outgoing transmission, a relay B has come to waste as a result, if the pulse had to have a certain length, a contact ## i of the pulse relay brought a relay E, a delay relay. At the end of the start pulse was now during the release time of relay E via 4i, 3e, 2b, 1c (contact of the occupancy relay C) via the b-core of the beginning resp. the 1st counting pulse is given 0 B-relay is now no longer came to the suit. According to the present invention, the ZIG / Vz or an equivalent organ as the first backward pulse of the election end pulse sent. As can be seen from Fig. 1, the b-wire also goes to the central one Facility ZE. After the end of the polling impulse, the ZE does not turn on Timing control pulse given to I0GW, which relays ZH and ZH1 (not shown) brings. The other processes are the same as already described, if the PR is only switched off when the called subscriber reports. Comes now the start pulse, then the voltage in Fig. 23 4i, 3e, 2b, 1c, b-wire, Z relay in Fig. 1, 8 zh 1, earth, Z relay brought to the pickup. About this circuit are also the counting pulses transferred during the call.

21 shows a further circuit arrangement of this kind Test procedure given over the d-wire. The election return pulse is therefore already given via the d-wire. The transmission itself is characterized by a timing pulse JUe, which is evaluated in the ZE. The ZE indicates that the selection criteria must be passed on via a cordoned off line, for example. This can be done through the respective transfer itself, or directly. for example on an audio frequency basis from the ZE. For the arrangement of Fig.

is this irrelevant. In Fig. 21, in deviation from II.GW, the Fig. 1 OG relay held via a contact of the PG relay. CG relay falls last Relay off, analogous to the pressure magnet AD in Fig. 1 IIGW. Comes from the ZIG via the incoming AC transmission for counting the end of the election pulse on and has this a predetermined length, a timing pulse is applied to the d-wire via 5e, 4i, 3b, 6cg sent to the ZE This is evaluated in the ZE by sending it to a relay, with ### - for example also a timing pulse of the same phase, but switched at opposite potential is (according to Fig.

1, ZE JL). Among other things, a timing pulse is given by the ZE, which brings ZH relay in I.GW/Fig. 1, which switches through the speech wires. In FIG. 21, the counting relay is not controlled via the b wire, but also via the control wire d. ZH relay ## puts a timing pulse in the I.GW with the contact lzh. to the Z relay on the d-wire 0. the 1st counting pulse on, we will be, just as with the end of election pulse via 5e, 4i, 3b, 6cg a timing pulse of such phase and > Potentials created so that the Z relay in the I.GW can pick up. Z-relay is a bistable relay, so that it stays in this working position. After the end of the counting pulse, determined by the release time of the relay E (Fig. 23 for example), such a timing pulse is sent via the rest side of the 5e contact via the d wire, which brings the winding ZI in the I.GW under current, at this there is an in-phase timing pulse. Z relay is brought back to its starting position 0 In this way, all counting pulses are given during the conversation to the I.GW 0 The other switching operations are the same as already explained in the description of Fig. 1. The pulse output can, if the Number of pulses is provided, take place in conventional form, that is, the pulses are transmitted via a wire by applying potential, but the pulses can also be transmitted directly or indirectly via the control wire Pulse marked by a timing pulse0 The remaining timing pulses for the control can then be arranged between these timing pulses for marking the selection criteria. The arrangement of such timing pulses for the dialing pulses is shown in FIG. Jw1, Jw2 etc. are the dialing pulses0 ZJ1, ZJ2 are the timing pulses that mark the beginning and the end of the respective dialing pulse. The timing pulses can, for example, have a length of 4ms0 With the timing pulse ZJ1, for example, a bistable relay is activated in the transmission and with the timing pulse ZJ2 this bistable relay is brought back to the starting position0 After 40ms then comes Again the timing pulse ZJI and after a further 60ms the timing pulse ZJ2. In this way the dialing pulses are then transmitted. The indirect transmission of the dialing pulses is shown in ## in Figs are, so the continuous pulse generator JG is connected to a comparison device in a pulse pause in the central device ZE. In FIG. 25, such a comparator device on an electromechanical basis is shown in principle. Of course, this can also be carried out semi-electronically or fully electronically, for example on the principle of the capacitor scoop arrangement.

The voter JS stores the voting impulses. The voter JV is controlled by the central impulses. If JS and JV have taken the same position, the stored pulses are equal to the number of pulses received from the central assembly in the selector JV. The central impulses are then switched off again. In the transmission of Fig. 24, to which the impulses are to be transmitted, is a relay AE, for example a bistable relay, which is also brought into the ZE relay during the impulse pause. The contact Iae this relay then switches the central impulses to the relay. AG AR, which is then brought to the rhythm of the dialing pulses 0 2ah and 3ah now apply alternating current to the line in pulses.

Since such transfers are already known, the mode of action the same not explained in more detail (z03. Land remote election by Dr. Rudolg Führer). if the dialing impulses stored in the words match the ones sent, when the JG is switched off in the ZE (Fig. 25), such a timing pulse is generated at the same time for transmission via the Steuerzader d sent that via the winding AEI the relay AE is brought back into the starting position ##. lae switches the central impulses away from the relay AH so that it can no longer be operated. On the same Art is transmitted every series of impulses.

In the case of carrier frequency transmissions, the character channel becomes with an ah-E contact groped. Alternating current pulses can also be present at the JG output in FIG. 24, these are then in accordance with FIG. 28 via the OLÜ present in the transmission transferred to the line with the help of the winding OLUI. For audio frequency transmissions this can be done in the same way.

If the selectors of the respective system are set with pulses, the impulse transmission can also be used, so that impulse distortion through the connecting cables or through the relay that transmits the pulses come about, can be switched off 0 In the network nodes, such as enotenatern, Main offices etc. one can also use the control cores to send the impulses in this way transmitted, so that always from the last one on the cordoned off line Transmission of the impulses without any distortion already being passed on will. When the pulse generator JG in the exchanges of a local network is synchronous such control can also be carried out via the local connection lines will.

In Fig. 26, the selection pulses J and the pauses P are shown.

In the breaks, the control pulses S are arranged0 These Ste-.

Erimpulse S are, as shown in Fig. 27, over the Pun Js and the contact lbv, which marks the beginning of the pulse comparison (Fig. 25, JV), placed on the relay "On". The connection of the central impulses JG takes place always in the interpulse period. If the selectors JS and JV have the same position in Fig. 25, so a relay EV (not shown) is brought to its contact 3ev the holding circuit of the "on" relay opens. Relay "On" drops out and opens the JG circuit in Fig. 25 and causes a timing pulse to be transmitted is sent in such a phase that the winding AEI in FIG. 24 comes into effect. AE assumes the starting position and, as already described, switches the central one # Pulse generator off. 1bv contact opens the pickup circuit at the beginning of the evaluation des Ein-RelaisO The arrangements of Fig. 24 to 28 can of course in many variants can be used. E.g. the transmission of the impulses in the transmission through two frequencies and by pulse groups. For example, the both frequenen are additionally marked with A and 8 pulses In this case, two bistable relays would then be required for the connection. The comparison would then have to be carried out in the ZE by means of two arrangements in accordance with Pig. 25.

In Fig. 21, as soon as the timing pulse JUe has been evaluated, on the d-wire, similar to that in Fig. 1, was described for the II.GW with the help of Timing pulses are switched ve ##, and this control takes place again from the ZE.

The marking in the preselection level according to Fig. 13 can of course also be made manually, especially if, for example, the criterion permanently resp. should remain switched for a long time independently of the participant.

In Fig. 29 a circuit arrangement is shown, in which the identification transmission between two switching devices and a large number of connection circuits, for example speech circuits, takes place via just one control line Fl (St). In the example, a number plate is transferred from a higher-level exchange (node exchange) to a subordinate exchange (end exchange). The control of the registers respectively. Voting takes place on a time basis as already described in FIGS. 1 to 20. The criteria are marked by timing pulses in the central control unit ZSt and in the switching device OGW / LW synchronously doh.

the timing pulse generators run synchronously. in the example the setting should be of voters are done on an impulse basis. The impulse transmission then takes place accordingly 24 to 27. Not all dialing pulses are transmitted from the ZSt, but rather in a pause of the central pulse generator (Fig. 26, S) a timing pulse is given, which causes the respective voter. A timer relay is sent to this voter according to AE Figi. 24 the engine started. Was in the comparison facility determined (according to Fig. 25), - this is housed in the present case in the ZSt, -iass the number of pulses to be sent and stored has been reached, then in the following Pulse pause again such a timing pulse is sent, which is a relay at the selector brings and brings both windings under current, so that the voter is shut down. (according to AEI in Fig. 24). The node office and the end office are therefore permanent dialing impulses that also run synchromously. The summary and distribution of the control channels of the different lines is in the present case by a time division multiplex system ZM vorgenoxen9 which is connected to the line by a corresponding modem. (Mon). If the number of lines in one direction is too small, several can be used Directions are interconnected on a time division multiplex system, in Fig.29 z. B.

the directions r2 and r3 for the ZM3. Are the identifiers in the received For example, page stored in a register, you can set the continuous pulses accordingly Select Fig. 26 much smaller, for example lom's pulse, 10 ms pause.

The timing pulse generator and the permanent selection pulse generator are normally dimensioned in such a way that there is a discrepancy between the of the node office and the end office is only possible in larger time intervals. Therefore, no ongoing synchronization is necessary. In the present case, timing pulses are provided for the SyneXB chronization on the transmitting side and relays are connected to the timing pulse ### on the receiving side. If, for example, synchronization is to take place every hour, the ZSt sends a synchronization timing pulse which brings a relay SY to a predetermined output, which now switches off the timing pulse generator, for example.

with the next timing pulse the relay SyI is brought, that switches the timing pulse generator on again 0 If it is the distribution speed The switch-on relay Sy and the switch-off relay SyI can be used in two different ways Outputs are actuated with the same timing pulse.

FIG. 30 shows an extract from an arrangement similar to FIG.

29, only a storage takes place in this and, if necessary, Revaluation.

The common control channel in FIGS. 29 and 30 can be seized not only in the incoming but also in the outgoing direction, for example if the transmission provided in the end office is for two-way traffic Different timing pulses provided for both directions0 The circuit arrangement of Fig. 24 to Fig. 28 can of course also be provided with push-button selection. The touch selection criteria are then marked and, for example, in a contact pyramid 25 converted into pulses according to the selection criteria in the form of several pulse series of the same or different pulse numbers, each marked by different frequencies, as already mentioned in the description of FIG. 24, the transmission of the beginning and end of the pulse series in the case of marking with the same pulse series over one connecting wire and in the case of marking with a different number of pulses per pulse series over different connecting wires, lead side
