Abstract

Setting of final selectors or similar elements is performed by marking. Marking signals remain when the output is engaged, so that testing for the line being free is performed by a selector arm or wire, with a time position pulse circuit provided for testing from final selector to subscriber circuit for equivalent unit. Switching means are provided in the final selector which become active when the line is free, and transmit switching processes (e.g. ringing) in the selector directly or indirectly to the route. a further time position pulse circuit is closed through the same arm or wire, following switching means in the first time position pulse circuit. Switching means are also provided at the engagement side which become active and open the time position pulse circuit.

Description

Circuit arrangement for self-dialing systems, at

those setting the voter, preferably LW on a marker basis he follows.

The present invention is concerned with a circuit arrangement for self-dialing systems, where the setting of the voter, preferably LW on Marking basis takes place.

Circuit arrangements of this type are already known. With such a known arrangement, it was necessary to identify again if the exit was occupied of the voter and the exit. Considerable effort was required for this. Such arrangements were necessary, for example, in telephone systems To be able to wait for a busy exit0 The present invention avoids this great expense of switching means by the LW or equivalent organs the marker at the exit remains even if the exit is busy, in such a way that the check on price one bezw over another arm. Core in the way takes place that over thesebezw. this switched a timing pulse circuit is, in which when the output in the LW is free, the switching means in this corresponding switching processes directly or indirectly (via the central device) initiate (zOBo call) and that via the same Ari another timing pulse circuit provided iat, which only with the help of switching means in the Zeitlageprüfstroikreis become effective, it is closed and the occupancy switch output takes effect brings.

The invention will now be explained in more detail below with reference to the drawings. FIG. 1 shows a call searcher AS, an I.GW, a relay search selector RSW, a central device ZE and a IIoGW. General known switching processes are only explained to the extent that it is is necessary to understand the invention. If a participant picks up a subscriber, the A8 will adjust 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 dialing, 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 is done on a timing pulse basis, which will be specifically described later.

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 erot in the WE. The number of memory units depends on the circuit of the rotary selector away. With 56 sohritten a time requirement of, for example, 350 ma is necessary, In such a case, memory is sufficient 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 there is a changeover to tone frequency selection in the WE. There. Changeover criterion can can either be determined from the key figure, or by means of a return indicator via a control wire. The same is required for some local connection cables. There is an advantage when the LW is reached, if this corresponds to the present one Invention is controlled, given a return mark. This ensures that this can be set to the selected adjustment step in one turning process.

As already mentioned, the RSW is started via 3c, 4ch. If a central unit ZE is free, it is connected to the AS / I @ .GW via the RSW. In the ZE, a timing pulse is switched on via 34ch, which is also in the AS / I.GW with the opposite potential on the relay winding OH. CH relay responds now and remains in this position after the end of this pulse, as it is a bistable relay. 4ch open 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 pulses are picked up with relay A and given to the KAW with the 5a contact.

As already described, the weighing control is based on time namely in such a way that the election criterion and the wah) criterion assigned to this 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. Duroh the timing pulses at this contact are brought into the A8 / I.GW by relay X, a bistable relay.

The engine is started with 12x. Did the storyteller through the election impulses When the specified output is reached, the coincidence goal is reached. in the W come switching means to the effect that put earth potential in the pole on 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. given who the relay brings to suit. Before this pulse, a timing pulse is applied to contact 40xI which brings X-RElais into the starting position via winding XI in the AS / I.GW. 12x opens the circuit of the motorf. 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 character was taken from the i-Ader / RSW switched off.- With the shutdown of the voter, the c-core was at the same time of the voter brought the CG relay in the II.GW. 15cg opens the marking circuit. The output marking timing pulses are then switched off and the second GW is occupied marked. 25ag switches the d-wire through to the following voter. Is the The next series of dialing pulses is saved, the 36xg contact is closed in the ZE and brought in the II.GW XG relay. The impulse is transmitted above the vein. 18xg leaves the voter on. In the following LW lies over the 15cl contact (Fig. 10) the exit marker. Is the output determined by the dialing pulses free, then there is coincidence again. In the WE is again to the wire a of the RSW Earth potential applied, which brings both motor windings under current about 19xg. Of the As a result, the motor is stopped on this output. In the ZE, the As a result, a tent position pulse is switched on again via a contact (not shown), which allows the XGI winding to take effect in the second GW and the XG relay again brings into the starting position. 18xg switches off the running circuit of the motor and 19tg the shutdown circuit. The indication that the next voter is an LW, is marked by the JL timing pulse, which is switched on in the ÖW and over the 3dll and the a-wires of the voters of the ZE is fed. This is where the JL relay speaks at which there is also a time slot in the pulse of the same phase. The JL relay causes dzss the setting of the LW takes place and, if necessary, switches the evaluation device in the WE accordingly. When the engine in the 2nd GW was stopped, the CL relay was brought in the LW at the same time, that prepares the transmission wire d for the output marking for the output of the LW ßoiltet. Once the tens and single pulses have been saved, the ZE 39xl contact closed, at which such a timing pulse is in phase with the timing pulse of the XL relay is in the LW. As a result, the relay is now brought into the working position. The impulse is transmitted via the a-wire of the voter. About 5x1 will now the engine started. 16xl switches the output marking pulses via the #### d wire to the WE in the ZE. There is again coincidence between those determined by the impulses and the timing pulse switched on at the output d of the LW, then in the WE brought a holding medium that applies earth potential to the c-wire of the RSW. ##Above the c-arms of the voters and the 25xl contact in the frW then both motor windings come under power. The voter is shut down. In the ZE, the 41xll contact closed, to which a timing pulse is applied, which is in LW via the XLI winding the relay XL brings it back to its starting position. 5x1 opens the running circuit and 25x1 the shutdown circuit of the selector. Subsequently g circuit and 25x1 the shutdown circuit of the selector. As a result, over 42pl in the ZE relay brought in the LW..17pl continues 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 43m1 in the ZE a timing pulse is now triggered, which brint @ gt in the M relay. 6m contact switches ringing current to the subscriber loop. After approx.

1000 mii, a timing pulse is given to lW via 44mlI, the .4a Brings relay M back into its initial 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 ringer current from the speakers. 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, since the M relay was already in the initial position. The 9a contact switches the voice wires through and removes the short circuit of the Al 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 of 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 28z1 contact applies voltage to the b-wire via the throttle DrIl-Wioklung and the contact 27zl for symmetry the throttle DrI-winding via a capacitor to the a-wire. Before the ZE is now activated, the control must be switched from the a-DAder to the d-core, which is no longer needed for the selector shutdown. A control, ie shutdown of the selector via the a-wire, is not appropriate for the larger currents required. It is only possible if there is an electronic control system for each voter, one from the ZE Get a standstill impulse. Such an arrangement is shown in FIG. - For staring the ZG relay in the I.GW, the relay in the II.GW and the DH relay in the LW, a pulse of the same phase can be provided. 14zg, 17bg in Fig.1 and 2dh in Pig.1O switch the control relays to the ed wire. In the pole, the relay ZH in the I.GW.BGH in the II.GW and DL in LW (Fig. 19) is controlled with the contact 32zh in the SEZE, to which there is a timing pulse. The contacts 9zh, 102h in the I.GW, 16bgh in the II.GW and 3dl1 in the LW (Fig. 10) switch the control relay away from the a-wire. ldll switches through the speech vein a in the LW. The calling subscriber is now connected to the called party. The central device ZE is now activated.

If, for example, a remote dialing transmission was switched on instead of the 2nd GW, 60 a timing pulse was sent from this to the ZE via the control wire. After evaluating this in the ZE, a timing pulse ZH1-Rel3is brought to the I.GW (not shown). 8zh1-Kcntakt switches earth to the Z-relay, so that a count is guaranteed during the call. A decade mark is not required, i.e. the remote operator can optionally over every 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 m. 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 A relay drops out and, in the sequence, the 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 activated for @@ ie. In the I.GW, all trigger timing pulses are routed to the ZL point. When triggering, a predetermined time sequence of the switching processes must be guaranteed so that the control wire, which may go over several selection levels, is only released when all relays in each selector have been brought into the starting position, always starting from the last selection level, or, if necessary, at the same time. In the present case, ndor LW is triggered when the calling subscriber hangs up, regardless of whether the called subscriber hangs up. Only when the output marker pulses are on the d-wire again, the respective voter is released again. The d-wire is interrupted by contacts * e ad of the pressure magnet, as a result of which the pressure magnet must drop out as the last switching means and of course also 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 (not shown) u 1st timing pulse 2o LW, DLI (not shown), II.GW (Fig. 1) BGHI (not shown), I.GW, ZHI = 2nd timing pulse 3rd LW DHI (not shown), PLI, II.GW, PGI, CGI, BGI, ## I.GW, PI, CHI, ZGI = 3rd pulse Since the principle of the release process is shown in Fig.5, the individual switching operations, which are known from existing selectors, are not so specified. There are therefore also different relay windings not drawn respectively.

mentioned. Because the switching operations are so simple, so is the Circuit perfectly clear to the expert.

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, 2ch. Above The three trigger impulses listed above are then successively generated in time which then in sequence the relays listed under 1 ¢ 29 and 3 in the Bring the starting position. The PL, PG and P relays in the three options now give the Free pressure magnets 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 able to be occupied 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, but powder on 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, I.GW does not affect the impulse generation has, one is in the central device for the relay receiving the pulses Opposite winding provided so that the current through the C relay does not affect has the impulse gift. There are of course other options with auxiliary relays.

When you select a button, the a / b wires are switched through directly to the ZE.

In Fig.5 is the basic circuit of the triggering of the three selection levels shown. In this example, this takes place in the direction of the connection establishment. Of course, depending on the called subscriber, a Reverse release can be carried out. The OFF relay is then arranged in the LW. During the operating state8, criteria can of course be used via this control wire are transmitted on a time-slot basis, in accordance with the principle of triggering one Connection of the counting voltage and the flicker stop sign is also not necessary, A start character can, for example, also go up to the I.GW or the last arriving Remote dialing transmission are transmitted. The final character can also go up to the last incoming remote dialing transmission or equivalent transmission are transmitted, so that the Lw can be made even cheaper in terms of transmission.

In Fig. 7 the marking of the decades of the group selector is shown. At the outputs of arm d (Fig. + 6) are always the same at each output of each group Decade pulse switched on, e.g. dark. When setting group selectors, then in the ZE Fig.6, for example, the relay selector db corresponding to the dialing pulses set. The relay selector M for marking the single pulses is here not required and therefore switched on via the initial potential, since the Evaluation is carried out according to an AND circuit. Lies during the course of the Motor selector the same decade pulse (in phase) at an output as at the dM magnet, so the electronic link is opened. PZE relay in Pig.6 responds then and schaltot with its contact pze potential to both windings of the motor. Of the This stops the motor. 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 via point S until shutdown is complete. To avoid 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 JL (FIG. 10) is sent from this. In the ZE this becomes evaluated Fig. 1, Jb 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 0 Does the one on the d-arm match the decade and units pulse in the ZE, the electronic device is opened again (Fig. 6, El. PZE relays speak up and apply potential to both with a 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.

A Arrangement according to Fig.3 can be provided. In the shutdown circuit there is more than 3x Series resistor Wi switched on and parallel to it a relay H, which is a bistable Relay can be. During shutdown, the motor windings are energized, this creates a braking effect. Only with the response of the E-Rolais is then with ih the shutdown process is initiated. The marker arm d can do something in addition can be switched in advance.

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 mg. 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 UZL Ausl. In the I.GW 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 elements. If monostable relays, e.g. ESK relays, are used in this arrangement, then one winding for the suit and for shedding, and the other winding for holding can be provided. Before the ZE is switched off, another relay is activated Ul also brought about a timing pulse, which then brings a relay U, that makes the switch. You can also control the U relay directly if ea is placed in front of the u-contact.

In Fig. 18 the control relays of the LW shown in Fig. 10 are shown namely monostable relays, e.g. ESE relays. XL relay is triggered by a timing pulse brought and then continues through its contact 3x1 and its winding XLI. The other relays are also activated by timing pulses held by its own contacts and a second winding. Since the relay XL, however controls the running and stopping of the motor selector, it has to be done again at any time be brought individually to the starting position0 There is therefore a own relay XLA with its own timing pulse required. With 2x1a becomes then, if necessary, the holding circuit of the XL relay is opened, so that the IL relay again switches back to the starting position. As shown in Figure 4, the Triggering a trigger timing pulse is only required for groups of relays, e.g. the pulses 1, 2, 3 after the off-pulseO Lead holding circuits of these groups via a contact of a relay, each is brought with a timing pulse 1, 2 or 3 and in each case with its contact lets the group in question come to waste by opening the holding circuits. 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 the relays AU2 and AU3 accomplished. The contacts 8au2 and 10au3 then open the corresponding ones Holding circuits. In a circuit according to FIG. 9, the ejection relays AU1 to AU3 ni not necessary, as the pull-in winding is also used as an ejection winding is switched. However, an XLA relay, for example, is necessary because the XL relay must be brought back to the 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 the Pig.

10, the output marker pulse was triggered by a contact of the Ba occupancy relay, in Fig. 10 20cn, switched off. 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, , in which the PD relay is activated if the subscriber circuit is not occupied, so that the call and the following switching operations can now be processed in the LW the 2pd contact is now closed to the second timing circuit. above this can now respond to the CE relay in the subscriber circuit. 3cn switches the test position pulse so that another LW can no longer access this output. When busy The PD relay cannot be activated at the output, but further ones 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 BS on the basis of time (not shown). Of the participants has to dial his own 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 in the subscriber circuit then comes. 5nsn contact switches the test timing pulse away to the subscriber on subsequent calls to be marked as busy. on the working side of this contact will be at the same time a timing pulse nsr is applied at the same time.

If the subscriber identified in this way is called, he continues to speak Shutdown of the selector via the nsr timing pulse on the KSR relay in the LW, the with a contact an indicator to the ZE corresponding to 22a in Fig0 10 gives. Of the ZE then the calling subscriber receives an acoustic announcement. Will the participant delete this authorization again, he enters a code in the PR, possibly with his own phone number, the ZE will now give a timing pulse to the LW, which brings a KSA relay in this. With 6nsa a timing pulse circuit is created Closed via the c-arm in which the NSNI winding is located0 This comes through this Timing pulse energized, which brings the NSN relay back to its original position will. It was assumed that it was a bistable relay a large number of such authorizations can be marked in this way.

If necessary, the XSE 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 very large internals, the same can be done with the help of a central Arrangement happen which, for example, be designed similar to a corrector can.

14 shows a circuit arrangement in which a double check 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 The function is the same as was explained in the description of FIG. on On the LW side, for example, for a group of 10 LW, the test timing pulses are J1 to J10 and the occupancy time pulses jnl to Jn10. In the subscriber circuit are per participant respectively. Output of the LW via the 7cn contact the timing pulses ## - b J1 to J10 (test circuit) and on the occupancy circuit, i.e. on the CN relay the Timing pulses Jn1 to Jn1O.

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 testing, so a second checking LW may have to overflow again.

In Fig.16 a circuit arrangement is shown in which the respective Voters from the number of steps that the voter runs in the form of impulses central facility ZE is given. m2-Kontakt is a voter contact, for example is pressed with every 2nd step. There is an electronic counter in the ZE, the exactly one overflow is marked and then the voter, for example group voter stops. Ny After the test relay has responded, this pulse circuit, so when checking the voter for a free exit, interrupted and that through the contact pg. The counter in the ZE only comes when the exits are occupied, for example of a GW, to the effect. If the voter has found a free exit, then with the control of the test relay, for example in Fig. 1 PG relay in the II.GW, also that The counter is brought back to its original position.

Since all dialing systems are coordinated with decadal control, you can not all outputs, for example, of a 112-part voter with the ones and This can of course be offset by hunt groups Keypad dialing to equip the telephone with more digits is not practical. 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 marking with 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 numbers is in the central facility shown according to Fig.6. So another relay selector is required, which then takes up the 30 digit. This is also to the AND or. OR circuit connected. If the third relay selector is, it can of course also be an electronic one Be a counting element, not required, if there is such a potential at the starting position, that the 1st and 2nd code numbers can be evaluated (tens and units code).

There are many conversion options, for example you can choose three-digit LW codes from 100 to 199 and from 200 to 212. It is only useful for pulse dialing choose low 3-digit digits. One can of course also plan 224-part LWs from Pall to case. This depends above all on the speed at which the selector is set.

There should also be no waiting times.

The occupancy criterion can also be via the d-arm, i.e. via the same Arm via which the exit marker is given. The occupancy switching means CN in FIG. 10 then applies a criterion yn to the d wire with its contact.

It is useful to have a special busy time criterion for each output create, for example in the way it is shown in Fig.11. Between the individual output timing pulses e1, e2 etc. then have the busy timing pulses eb1, eb2, etc. There is then an evaluation in the central evaluation device ZE EE for the free pulses and an evaluation EER for the busy pulses. Both can only become effective if the respective time slot pulse series is currently available is, at EE the impulses e1, e2, etc., at EEB the impulses e1, e2, etc. The switching means eM for marking the single-choice criteria must then also have the busy pulses, e.g. e1, eb1, e11, eb11 etc. The output marking on the LW can also remain. In this way, an authorization mark can bezw. Markings according to Fig. 13 UOU.

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