Description

Circuit arrangement for monitoring code number current impulse series in telecommunications, in particular telephone systems with dialer operation, in telephone systems with voter operation it is necessary to set a connection route to monitor sent code numbers in order to carry out special switching operations for certain code numbers to trigger, for example to prevent the establishment of unauthorized connections or to send out a criterion that directs a reversing selector to a different direction, for example on a cross connection or a special signal to a particular one Place, for example to send to a placement official's place, etc. There these functions should only be carried out when certain identification numbers are selected these special identification numbers are referred to below with function identification numbers.

For the purpose of evaluating the identification numbers, tracking mechanisms are known provide that in certain positions the triggering of the special switching process cause. It is required for multi-digit function codes. the single ones To save the code numbers until after the total code number has been recorded by the follower. In known arrangements, relays are used for this, the number of which corresponds to the number of digits the function identification number grows and can be relatively large under certain circumstances, which adversely affects the economy of the system. Because of this i, st one switched to using step relays instead of normal relays, in such a way that that different code numbers are stored in the individual levels.

The invention aims to further simplify the storage and evaluation of the facilities serving indicators and achieves this by that code numbers of characteristic for the execution of certain switching processes Identification numbers (Functional identification numbers) are stored in capacitors, e.g. B. by charging, and one connected to a storage capacitor after selecting the last code number Switching means; is influenced by it for the purpose of triggering the switching process, e.g. B. by discharge.

Arrangements with storage capacitors are already known, however serve other purposes. So obtained with a known number encoder, approx Depending on the keys pressed, call charges and capacitors of different sizes Relays due to the different high capacitor discharges: variable drop times, by which the number of current surges to be transmitted is determined. With another known arrangement turn through certain dimensioned capacitor charges and discharges the time intervals between the metering pulses to be sent to the subscriber's meter adapted to the value of the connection.

Some exemplary embodiments of the subject matter of the invention are shown in the drawing. All switching devices and circuits that are not absolutely necessary for its explanation have been left out for the sake of simplicity and clarity. In the examples according to FIGS. 1 and 2, two-digit function codes are assumed, and FIG. 2 also shows the possibility of triggering the switching process awake recording a single code. In the arrangement according to FIG. 3, three-digit function codes are assumed. To make the overview easier, the function identification numbers for the individual figures are shown in dash-dotted boxes. Accordingly, in the arrangement according to FIG. I, the numbers 23, 57, o9 and oo are function identification numbers. At the top left of the drawing a part of a connection path is shown, to which the follower for monitoring the code numbers is assigned. If the upstream connection device is occupied, relay A responds: minus, winding of relay A, voice wire a, loop formed in the upstream connection device, voice wire b, resistance Wi i, earth. = gm contact 2 - the circuit for relay T is closed: earth in the upstream connection device, wire ML, contact 2 a, winding I of the relay T, minus. At contact ia, a point in the upper speech artery of the continuing connection path is closed. By connecting the ground potential to contact io a, the i \ Tümmernstromst.ße picked up by relay r4 are transmitted to the following connecting devices, at contact 2: c, to relay T, which in turn passes them on at contact 28i to the rotary magnet DM of the follower mechanism. During the assignment, earth potential was also applied to wire G from the upstream device. After opening the contact i6i, the following circuit is established for relay B: Earth in the upstream connecting device, wire G, resistor Wi7, winding of relay B freed from short-circuit by contact 164, switching arm 4 dm. Of the follower in the rest position, contact 25 v, resistance Wi 4, minus. Via contact i8 b, resistance Wi 2, minus, relay B is placed in a holding circuit that is independent of the switching arm 4 dm.

It is assumed that the subscriber sends out a digit with which none of the function identification numbers begin, e.g. B. the number 4. At the first drop, the relay J by the first pulse, the following circuit for the relay V is created: Earth, contacts 6 b, 9 i, 8 f, windings II and I of the relay V, minus. The relay V shorts its winding II at contact 7 v. The relay dropout delay achieved in this way is sufficient to bridge the series of current impulses. The rotary magnet DM of the tracking switching mechanism receives the current surges in the following way: earth, contacts 28i, 29v, 31f, magnet DM, minus. The first current surge took effect when contact 29v was closed. The switching arms of the follower are thus on the fourth contact after the transmission of the series of current impulses. By prolonged opening of the contact 9 i after the series of current impulses, relay TI is caused to drop: its home circuit, which is open at contact 32 b, runs over switching arm i dzn of the follower. Switching arms 2 dm and 3 dm in the isolated position 4 do not result in switching: The following circuit is closed via switching arm 4 dm: Minus, resistance Wi 4, contact 25v, switching arm 4 dzn in position 4, which is connected to contact 35 by a common line , the follower is connected. Winding II of relay I, earth. A continuous circuit is thus closed for relay I, so that when further series of numbered current impulses are sent by this relay, no further pulses are sent to the follow-up transmission. The switching arms of the follower remain in position 4 for the duration of this connection. The connection is continued: by interrupting the upper speech artery at contact ia or io a.

The same processes occur when the first to appear: the follower transmitted code numbers current impulses corresponding to numbers i, 3, 4, 6, 7, 8 and 9 are sent out. These are the digits that are not the first digit of the function identification numbers form.

If a code number consisting of two current surges arrives, the switch arms of the follower are set to the second contact. The capacitor C i is now switched on via switching arm 2 dm. After waste .of relay V, the following circuit is established: minus, winding I P of the relay, contacts 34Q, 35V, 36 b, switching arm 2 dzze of the follower in position 2, the capacitor C i, earth. As will be explained later, the storage capacitors C i, C 2, C 3 have been discharged before the use of the tracking mechanism: In the above-mentioned circuit, the capacitor C i is charged. Relay P is also energized by the charging surge in the same circuit. It closes the following holding circuit: earth, contacts 23 b, 22 sp, 24 p, winding III of the relay P, resistance Wi 3, minus. At contact 34 P, winding I or relay P is switched off, while the following current flow is formed by closing contact 38P: minus, winding II of relay P, contacts 38 P, 35 v, 36 b, switching arm 2 dm in position 2, capacitor C i, earth. In this circuit, the charge on the capacitor is maintained. Via switch arm q. dm in position: 2, a continuous circuit for relay J cannot be created because contact: 2 is not brought up to the collecting line and is separated from contact 35 of the follower and from winding II of relay J by contact 26P. As a result, the follower is able to take up another series of current impulses. If a second number is selected which, together with the previously transmitted number 2, does not result in a function code, for example the number q., The switch arms of the follower are brought into position 6. There is no switching process via switching arms 2 dm and 3 dm in position 6: g. Via switch arm q. In position 6, winding II of relay J is switched on. For the relay J, the continuous circuit is established again, which makes it impossible for the follower to accept any further current surges. If, however, 3 is selected as the second digit, the switch arms of the follower reach contact 5. The following circuit is established via switch arm 3 dm: earth, winding I of relay Sp, contact 39 v, switch arm 3 dm in position 5, capacitor C i, earth. The switching arm 3 dm is connected to the same capacitor according to the second code number, which was charged via switching arm 2 dm after setting by the first code number. In the circuit mentioned, the capacitor C i is discharged via winding I of the relay .'p, which is thereby excited. It lies in the following holding circuit: earth, contacts 23 b, a1 sP, toi, winding II of the relay Sp, minus. A criterion for initiating the special switching process is now transmitted to the upstream connecting device via wire Kt 'by applying earth: earth, contacts 6 b, ii i, 12 v, 13P) i4sp, wire KU. As mentioned, this can, for example, initiate a reversal in a different traffic direction or the activation of a signal or the prevention of further connection establishment, etc. The capacitor C: 2 was switched on via switching arm 2 dm in position 5, which is charged via contacts 36b, 35v, 38P and winding II of relay P after the relay h has dropped out of contact 22 sp no holding circuit is established for relay P. The continuous circuit for relay 1 is closed via switching arm 4 dm in position 5 and contact 26p, so that still incoming series of numbered current impulses leave the follower unaffected.

It is now assumed that series of current impulses corresponding to number 2.8 are transmitted to the follower. After the first series of impulses, the relay P is switched on via switching arm 2 dm in the manner described, at the same time as the charging of the capacitor C i, which relay is placed in the aforementioned holding circuit. After recording the second digit 8, the switch arms of the follower are in position io. The shift arm q. dm is not directly connected to the contact 35 of its contact bank, but via contact 26P. The relay P had been energized, so that since the continuous circuit for relay J 'does not come about, the follower would be released for further switching. This must not be because (the number 28 does not represent a function code number. In this case, the following arrangement takes effect: After the relay V has dropped out, the following circuit is closed via switching arm 2 dm in position io: earth, capacitor C 3 not charged, contact io, switching arm 2 din, contacts 36 b, 35 v, 38 P, winding II, of the relay P, minus. In this circuit, the capacitor C 3 is charged Designations A and E for winding start and winding end marked, (the holding winding III is opposite to that of the relay P. The relay P is thus thrown off and the holding circuit at contact 2 fp is interrupted. Via switching arm d. Diza in position io and the now closed contact 26P the continuous circuit for relay J is closed, so that it is not possible to record further series of code numbers.

If, as the first, a series of current impulses corresponding to the number 5 is transmitted to the follower, then the capacitor C: 2 is charged via switching arm 2 dm in position 5, the winding I: of the relay P is excited by the charging impulse and the holding circuit for this relay is formed . The charge of capacitor C 2 is maintained via minus, winding II of relay P, contacts 3: 8 P, 35 v, 36 b. If a digit is now selected as the second, for example: which, together with the first digit 5, does not result in a function code, then the switching arms of the follower are in position g after the second digit. The contact g in the contact bank of the Schaltarmes4dm is directly connected to the contact 35 and the winding II of the relay J via a bus, so that the continuous circuit mentioned several times for this relay is established and no further absorption of current surges occurs. If, however, the number 7 is selected in place of the number .4 (57 - is a function code), the switch arms of the follower are in position 1.2 after the second number. The previously charged capacitor C 2 is now on the switching arm 3 dm, which, after the relay V has dropped, gives its charge via winding I of the relay Sp. The relay .S'P responds, places itself in the aforementioned holding circuit via contact 21 sp and transmits the special identifier via the line K'fl to the upstream connecting devices by closing the contact i4sp.

If a series of impulses corresponding to number 55 are sent over the line, after the capacitor C 2 was charged via switching arm 2 dm in position 5, the follower after the second digit is brought into position io. Since there is no permanent circuit for relay T via switching arm 4 dm in position io when contact 26 p is open, but further influencing of the follower must be avoided because 55 is not a function code, the same processes are effective as when number 28 is selected, namely switching on the Counter-winding II of the relay P, due to the rush current when the capacitor C 3 is charged and the relay P drops out, which closes the continuous circuit for the relay T at the contact 26 p. `.

If a series of current impulses corresponding to the number o is transmitted as the first, the follower moves into the position io_. After the relay V has dropped out, the capacitor C 3 is charged via the switching arm 2 dm and the relay P is energized. If the second is not one of the digits 9 or o, i.e. h: So no function code has been selected, the continuous circuit for relay J is closed in the manner described via switching arm 4 dm. If, however, a series of currents corresponding to the digits 9 or o arrives as the second, the switch arms of the follower move to position i9 or 20. Via switch arm 3 dm, the capacitor C 3 charged via switch arm 2 dnc in position io is switched on Drop in relay V releases its charge via winding I of relay Sp. In the manner described, the special criterion is passed on to the upstream devices by relay Sp. When the final signal is given after termination of the connection, earth potential is switched off from the lines G and ML in the devices upstream of the follower. After the resulting drop in relay B, the following circuit is established: earth, contact 32b, switching arm i dm on the segment; contacts 3o v, 31f, rotary magnet DM, minus. The rotary magnet responds and switches the follower arms one step further. The following circuit is closed via contact 4 dm: earth, contacts 5 b, 4 dm, 3 f, winding I of relay F, minus By opening the contact 3 f, the winding II of the relay F is included in the circuit mentioned. By opening the contact 3 if the circuit for the rotary magnet is interrupted, so that the circuit for relay F is also opened on the account file 4dm. The circuit for the magnet is re-established at contact 3 if and the switching arms of the follower are brought to the next contact. This interplay between the rotary ma gneten DM round, the relay F continues until the switching arms of the follower have reached the rest position.

When passing through the last three positions of the follower, all storage capacitors are switched on one after the other via switching arm 2 dm and placed in: the following circuit: earth, contact 37 b, switching arm dm, contacts 33, 34 or 35; Condensers C i, C.2 or C 3, earth. Capacitors that are still charged are discharged via this circuit, so that when the follower has reached the rest position, the capacitors are ready for a new storage of the code number. Then the continuous circuit for relay J is also interrupted. The holding circuits for the relays P and Sp have been opened at contact 23 b.

In the example shown in FIG. 2, other two-digit function identification numbers, namely the numbers 70, 78, 8o and 86 and, for the sake of completeness, also two function identification numbers 9 and o have been assumed. Only the three switching arms 2 dm, 3 dm, 4 dm of the follower are shown with their wiring that has been modified from Fng.i.

If a series of current impulses corresponding to ID number 9 or o is sent, the following circuit is closed via switching arm 3 dna of the follower after relay V has dropped out: (Fig. I) Earth, winding I of relay Sp, contact 39 v, (Fig. 2) Switching arm 3 dni in position g or io, contact 41 p, resistance Wi 5, minus. The relay Sp is excited here by the normal office battery without the use of capacitors. Relay Sp then immediately transmits the identifier for the particular switching process to the upstream connecting devices in the manner described.

If a series of current impulses corresponding to number 7 is transmitted to the follower as the first, after the relay V has dropped via switching arm 2 dm in position 7, a circuit is established in which the capacitor C 4 is charged. The relay P responds, places itself in a holding circuit and, by opening the contact 42 p, releases the follower for further influencing. If a series of current impulses corresponding to the number ö arrives, the switching arms of the follower are brought into position 17. The capacitor C 4 charged via the switching arm: 2 dm is now switched on via the switch arm 3 dm of the follower. After the relay h has dropped, the relay Sp is switched on by discharging the capacitor in the manner described, which causes the forwarding of the criterion via wire KU. The contact 15 of the contact bank swept by the switching arm 3 dm is also connected to the capacitor C 4, so that the special criterion is sent in the same way when the function code number 78 is selected.

When the number 8o is selected, the followers are set to position 8 by the first series of impulses. About SchaItarm 2 is effected charging of the capacitor C 5. After the second surge grater, the switching arms of the idler are in position 1, 8, so that now via switch arm 3, the charged after the first impulse series capacitor C dna 5 is turned on and in the manner described by discharging the Capacitor the relay Sp is energized. Also, the contact 14 of the contact bank swept by the switching arm 3 dm is connected to the capacitor C 5, so that the relay Sp which passes on the special criterion is switched on in the same way when the number 86 is selected. If digits other than those in the function identification numbers are selected, the relay I is switched on in the manner described in the permanent circuit via switching arm 4 dm of the follower and the block is blocked against being influenced by further series of current impulses.

In the arrangement according to Fig. 3 dreistel.ldge are function identification numbers "accepted; namely the numbers 132 and 216. Compared to the circuit according to Fig. i and 2, the follower has one more switching arm.

After transmission of a current impulse corresponding to the code number i, the switching arms of the follower are in position i. The capacitor C 6 is charged via switch arm 2 dm: earth, capacitor C 6, switch arm 2 dfn of the follower in position i, contacts 5 1 b, 50 v, 47 p, 46sp, winding I of relay P, contact 44 p, resistor Wi 5, minus. Relay P is excited by the charging surge, which is located in the following holding circuit: earth, contacts 6o b, 61 p, winding III of relay P, resistance Wi 6, minus. Via switching arm 5 dm of the follower in position i, since contact 63 p is open, no permanent circuit for relay J, winding II is established. This enables the follower to be influenced by further series of current impulses. By closing the contact q.8 p, minus is applied to the switching arm 2 dm via winding II of the relay P, thereby maintaining the charge on the capacitor C 6. If a series of current impulses corresponding to number 3 is now transmitted, the switching arms of the mutant runner reach the fourth contact. The charged capacitor C 6 is now connected to the switching arm 3 dna. After the relay V has dropped out, the Zcondenser C 6 is discharged in the following circuit: earth, winding I of the relay Sp, contacts 54 sp, 55 v, switching arm 3 dm in position 4, capacitor C 6, earth. The relay Sp is energized and the following holding circuit is closed: earth, contacts 6o b, 59 sp, 58 i, winding. II of the relay Sp, minus. By closing the contact 45 sp, the winding I of the relay P is connected to the switching arm 4 dm of the follower via contact 56v. Via switching arm 5 dm in position 4, the permanent current circuit for relay J cannot be established because contact 64 sp is open. The follower can thus take up another series of current impulses. By closing the contact 53sp minus is applied to the switch arm 3 dm of the follower via resistor Wi6, so that the capacitor C 6 is recharged: minus, resistor Wi 6, contacts 53 sp, 55v, switch arm 3 dm in position 4, capacitor C6, earth. While in the arrangements according to Fig. I and 2, the transfer of the special identifier to the upstream connecting devices when switching on, the relay Sp (closing the contact i4sQ) took place, in the arrangement of FIG Relay Sp dependent, but also on relay P, which only after it has dropped by closing contact 13 p enables the transmission circuit to come about. After recording the second code, both relays P and Sp remain energized in independent holding circuits.

If a series of current impulses corresponding to the number 2 is transmitted next, the switching arms of the follower get into position 6. The winding I of the relay P is now connected to earth via contact 43 p. As a result, it has become the reverse of winding III. After relay V drops out, capacitor C 6 is discharged via winding I of relay P: earth, capacitor C6, switching arm 4 dm of the follower in position 6, contacts 56v, 45 sp, winding I of relay P, contact 43 p, earth . The relay P is thereby brought to drop, the holding circuit at contact 61 p is interrupted. Via normally closed contact 13 p and normally open contact. i4sp will now transmit the special identifier via line K ü.

If a series of impulses are sent according to the function code 216, the following are shown after transmission: the first digit the switch arms of the follower are in position 2. The capacitor C 7 is charged via switch arm 2 dm and relay P is energized, which is connected to the hold circuit via contact 61 p, while via contact 48 p to maintain the capacitor charge minus is connected to the switching arm 2 dm . The contact 63 p is open so that after the relay h has dropped out, the continuous circuit for relay T cannot be closed. The switching arms of the follower are set to the third contact by the next series of current impulses (a current impulse). The contact 3 of the contact bank of the switching arm 3 dm is also connected to the capacitor C 7, which was charged via the switching arm 2 dm. After the relay V has dropped, discharge takes place in the manner described via winding I of the relay Sp and this relay is energized. It lies in the aforementioned holding circuit via contact 59 sp and switches the switching arm 3 dm via contact 53 sp and resistor Wi 6 to minus. This immediately recharges the capacitor C 7. The contact 64sp is open, so that a further series of current impulses is taken up by the follower. The last series of current impulses promotes the follower to position g. After relay h has dropped out, capacitor C 7 is discharged via switching arm 4 dm in position g, contacts 56 v, .I5 sp, winding I of relay P, contact 43 p, earth. The relay P is thrown off so that the transmission of the special criterion via contacts 13 p and 14 sp takes place in the manner described.

After termination or connection, the relay B is brought to waste in the manner described. The follower is switched to the rest position. When the switching arm 2 dm reaches the contacts 34 and 35, the capacitors C 6 and C7 connected to these contacts, if they were charged, are discharged: earth, contact 52 b, switching arm 2 dm of the follower, contact 34 bz, w. 35, capacitor C 6 "or, w. C 7, earth.

In order to recognize the mode of operation and the correct operation of the arrangement shown in FIG. 3 @, some code number combinations which do not make up function codes are considered below. If a code number is selected first that does not begin with any of the intended function code numbers, for example the number 5, the switch arms of the follower come into the fifth position. The continuous circuit for relay J is closed via switching arm 5 dm : earth, winding II of relay J, switching arm 5 dm in position 5, contact 62 v, resistance Wi 4, minus. This makes it impossible for the follower to accept further series of current impulses. The same thing happens if the digits o and 6 to 9 are dialed first. With Wall of the digits 3 and 4, the continuous circuit for relay J would come about via normally closed contact 64sp. -Other code number combinations: a) 16: After the first series of impulses, the switch arms of the follower are on contact i. The capacitor C 6 is charged via switching arm 2 dm and the relay P is switched on in the manner described. By opening contact 63 p, further influencing of the follower is enabled. After the second series of impulses, the switch arms of the follower are on contact 7. In this Position does not take place via the switching arms 2 dm, 3 dm and 4 dm . Via switching arm 5 dm , the continuation of the follower is blocked by constant excitation of the relay J. b) r 2: After the second series of current impulses, the switching arms stand up Contact 3. The switching arm 3 dm comes via contact 3 in connection with the non-charged capacitor C7. The relay Sp is not energized. The continuous circuit for relay J is closed via switching arm 5 dm in position 3 and normally closed contact 64sp, preventing any further influence on the follower.

c) _ i 5: After the second series of impulses, the switching arms of the idle follower are in position 6. Via switching arm 4 dm in position 6: the charged capacitor C 6 is switched on. A switching process does not occur, however, since relay Sp remains unaffected and the switching arm 4 dm is switched off at contract 45 sp. The constant current circuit for relay .T is closed via switching arm 5 dm in position 6.

d) ii: After the second current impulse redhe, the switching arms of the follower are in position 2. Since the relay P is energized, if contact 63 p is open, no continuous circuit would be established for relay J, so the follower would be ready to receive a further series of impulses, although it is certain that there is no function identification number. The following arrangement prevents the follower from being switched on: Via switching arm 2 dm of the follower, the uncharged capacitor C 7 is switched on in position 2. The following circuit is created: earth, capacitor C 7, switch arm 2 drn, contacts 5i b, 5ov, 48p; Winding II of relay P, minus. The capacitor C 7 is charged and at the same time the winding II of the relay P is excited, which is opposite to the holding winding III. This causes relay P to drop out. The closed circuit for relay J is brought about via the dropped contact 63 p.

e) 1 3 i: After the second series of impulses, the switch arms of the follower are in position 4. After relay V has dropped, capacitor C 6 is discharged via switch arm 3 dm in position 4, contacts 55 v and 54sp, winding I, of relay Sp . Relay Sp responds, holds and switches on contact 53 sp via resistor Wi 6 minus to switch arm 3 dm, so that capacitor C 6 is immediately recharged. After the next series of impulses, the switching arms are in position 5. The relay J is switched on via switching arm 5 dm via the continuous circuit. Since relay P was not brought to waste, the transmission of the special identifier is omitted.

f) 26: After the first series of currents, capacitor C 7 is charged via switching arm 2 dm in position 2, relay P is energized and placed in the holding circuit. After the second series of impulses, the switch arms of the follower are in position B. The continuous circuit for relay J is closed via switch axis 5 dm.

g) 2 1 8: After the first series of impulses, capacitor C 7 is charged and relay P is energized. After the second row of shock waves, the switch arms are in position 3. Over switch arm 3 dm is now. the charged capacitor C 7 switched on: This capacitor is discharged via winding I of the relay Sp; which responds, so that the capacitor C 7 is immediately charged again via contact 53 sp, resistor Wi 6, minus. Contact64sp is open so that the follower can pick up another series of current impulses. After the third series of impulses, the switching arms are in position ii. Continuous switching on of relay J prevents the follower from being switched on. The special identifier is not sent. h) 2: 2 ;: After the second series of impulses, the switching arms of the follower are in position 4. The non-charged capacitor C 6 is switched on via switching arm 3 dm in position 4. Relay Sp cannot respond. Via contact 64 sp and switching arm 5 dm in position 4, the continuous circuit for relay J is closed.

i) 27: After the second series of impulses, the switch arms of the follower are in position 9. Since the relay Sp is not energized, the switch arm 4 dm of the follower is switched off at contact 45 sp, so no switching operation can be triggered via it. The continuous circuit for relay J is closed via switching arm 5 dm.
