SU58612A1 - Device for connecting two-subscriber devices to one station line - Google Patents

Description

The subject matter of the present invention is a device for increasing the capacity of an automatic telephone station (ATC) of a machine system with a five-point contact field.

According to the invention, to make a call and block the output of the called, whose device is connected with another device to one station line and one subscriber set, two relays PP15 and PP16 are entered in the register circuit and one PC7 relay in the linear distributor current distributor circuit (TLS) , depending on the seven-digit or six-digit number of the called subscriber, provides for the mutual switching of the apertures (a) and (b) of the specified TLS current distributor towards the called subscriber.

For drying out the same purpose, when long-distance connections, relay P13 is entered into the long-distance connection register, which is triggered by pressing button A.

To illustrate the effect of the proposed device, the following is an analysis of the register of Moscow PBXs.

As is well known, the Moscow Register scheme allows connections between subscribers both with six-digit and seven-digit dialing. This is achieved due to the presence in the register of relays PP13 and PP14. The first of these relays works when dialing the number as the first digit - one (A), and the second when dialing two (B), and in both these cases, the first recorder registers the sum of the two first digits of the number. Thus, when dialing the six-digit number 524563 and the seven-digit number 1424563 or 2324563 in all these three cases, the first registrar will register the mark.

It was believed that the register scheme would bring the maximum capacity of the Moscow network to 2,400,000 numbers by forming eight nodes of the incoming message of 200,000 numbers and eight nodes of 100,000 numbers. For each node in the IGI field, one frame is occupied, and in the DGI field, to obtain a capacity of nodes of 200,000 numbers, take twenty frames, one frame for 10,000 numbers. When dialing a six-digit number with indices B, D, D, E, F, I, K, depending on the second digit of the number, you can receive one of the ten ATSs included in the first ten DGI frames.

When recruiting a seven-digit omer with the A., AZ, and A, and A, A, A, and A, A, A, A dexes, the hell is connected to the same nodes (C, D, D, etc.), depending on which the number is given by the index of the seven-digit number. So, for example, AS In sum, gives 4 and, meaning m, corresponding to the index G in a six-digit number, will send a message to node G. However, if the six-digit number was dialed in, the node on the PBX included into one short circuit of the first If you dial up the seven-digit number, they will end up on the PBX included in one of the paiMs of the second decade. This is explained by the fact that when dialing a seven-digit number, with indices 1 and A, AZ, etc., the relay PP13 operates and, with its contact springs, makes the necessary switching in the register.

If the PP13 relay, with the exception of the first contact spring (a), which blocks this rel during its operation, fix all other contact springs in their quiet position, in other words, turn off the said springs and contacts from the circuit and make the corresponding connections their, then relay РР13, work, will only allow the first registrar to register the sum of the first two digits when dialing the letter M A, beginning with the letter A, but stop against the frames of the first ten of the DGI. Therefore, if in the six-digit and seven-digit number the last five digits are the same, and the first two digits of the seven-digit number in the sum will be the first digit of the six-digit number, will the dialed 1H be a six-digit number or c: EM1 digit number, still fall on the ODU and the same PBX and on the same string line (see the scheme of the Moscow PBX register).

As mentioned above, according to the invention, two relays PP15 and PP16 are added in the register; one relay PC7 is added to the LAN power distribution box. PP relay. 15 has two windings I and II, acting at different times and mutually opposite. Relay PC 7 also has two windings, but they both act in the same direction.

The wiring diagram of the mentioned relays with separate register elements and tle is shown in FIG. 1 and concludes as follows:

The second contact spring of the relay PP13 is connected to the tenth contact with 10 rows of C switches. PR2. The contact (b) is connected to one of the ends of the winding I of the relay PP15; plus is fed to the second end of the winding of this relay. The third contact spring of the relay PP 13 is connected to the contact spring of the relay PP16. The contact (c) is supplied minus the battery.

The contact (a) of the relay PP 16 is connected to the tenth contact 10 prs. F of the switch PR2. At one end of the winding of relay PP 1b, a plus is applied, and the other end of this winding is connected to contact (b) of relay PP15.

One of the ends of the winding II of the relay PP15 is supplied plus, and the other end of it is connected to the contact 11 of the row D of the switch PR2.

At one end of the winding of the PP 7 relay, minus is still fed, and the existing connection of the second end of the coil is broken, and this end of the winding is connected to the contact (a) of the PP15 relay.

The second contact spring of the relay PP15 is connected through a resistance R to the winding of the I-relay PP15; the contact (c) of the latter is given in m. inus.

The PC 7 relay added to the TLS will have the following connections: the common1 point of both windings of this relay is connected to PC 1-b; The end of the winding I PC 7 is connected to one of the contacts TLS-L - 1, and both contacts tle-L-1 need to be preliminary disconnected from the contact TLS-K-1 and RPM-V.

This can be done without any damage, since the connection (rj) with the RSP - in via TLS - L - 1 is duplicative of the connection through TLS-K-1 and therefore can be eliminated if you do not bypass it.

The second TLS-L-1 contact is connected to the wire (a), as shown in the diagram.

The end of the winding II of relay PC 7 is connected to the fifth contact spring of this relay.

Contact (e) is supplied with battery plus.

The secondary windings of the inductor transformer are interconnected as they are connected to the PBX, adapted to enable paired subscribers:

In the absence of a current in the relay PP16, its contact point is in contact with contact (a).

When current passes through the winding I of the relay РР15, the contact springs of this relay contact with contacts (b), (c), and if there is no current in this relay or when current passes through the winding II, the springs are transferred to quiet contacts.

The relay РР15 under the action of the winding I should work quickly.

When calling a subscriber, which contains six characters in his number, the connection with him is established in the usual order and none of the newly added relays takes part in the work. However, if this subscriber is one of the paired subscribers, i.e., if there is an esh, e subscriber with a semiconductor number, then his connection will be set up in normal order, but the call to it will be received via a single-wire system but the wire (b) with return through the ground.

If a subscriber with a seven-digit number is called, when dialing the first character, i.e., A, the relay PP13 is triggered and is blocked through its contact (a) via a circuit:

1. Minus, PP 13-a, PP 13, ICR-a, plus.

Due to actuation and blocking of the relay PP 13, a minus is applied to the contact 10 p yes F of the second switch PR 2, and to the contact 10 p yes From the same switch winding I of the relay PP 15 is connected.

After the WGI has completed a circular motion, PR2 will move the brushes from the ninth to the tenth position. In this position, the PR 2 switch will have to be delayed, at least the fifth digit of the number by this time.

and turned out to be recruited. The delay in the GO position is caused by the presence of a minus on the PR2-F, -10, due to which the PP 8 relay is energized. From the tenth position to the eleventh, the OL 2 switches after the relay PP 16 operates, thereby disconnecting said tenth contact of row F from the minus.

In the tenth position of PR 2, chains are formed:

2. Minus, РР 13-в, РР 16-а, PR 2-FE-10, РР 8, plus.

3. Minus, PR2-C-10, PP 13-6, PP 15-1, plus.

The presence of chain 2 delays the PR 2 in the tenth position. In circuit 3, a relay relay PP 15-1 is triggered and is blocked along the circuit:

4. Minus, РР 15-в, R, РР 15-1 plus.

By triggering PP 15--1, the first contact spring on relay PP 15 will go to contact (b), turn off relay PP 7 and create a circuit:

5. Minus, PC 1-6, PC 7-1, t-L-1, wire (a) (TWG, TIGI, TIV-C-6, RI-B, PP 3-b), PP 15-6, Pp 16 plus

Thanks to this, the PC 7 relay of the TLS current distributor, which will be occupied by the WGI, is triggered and blocked through its own winding P along the circuit:

6. Minus, PC 1-6, PC 7-II, PC7-d, plus.

If by this time the change to PP 16 still does not work, then the circuit 5 also remains closed.

Relay PP 16 also operates in circuit 5; after this relay trips, the tenth pin 10 p yes F of the PR 2 switch will be deprived of the minus and the PR 2 will switch its brushes to the one position where the circuit is installed:

7. Minus, PR 2-D-11, PP 15-11, plus.

Under the influence of the winding II of the relay PP 15, the contact springs of this relay are transferred, and the relay PP 7 is again connected to the wire (a), proving ready to accept reverse pulses. The relay circuit of the PP-16 is broken, but the PC-7 relay remains in

block your position through your abm; tku ii.

When the PC 7 relay is activated and blocked, it will switch its contact springs, connected to the source of the ring current, from contacts (a), (c) to contacts (b), (d), as a result of which a CURRENT current can be sent via a single-wire system by wire (a) to a subscriber with a seven-digit number. When using telephones with resonant calls, it is possible to carry out a two-wire system.

If the PC 7 relay did not work, i.e., a subscriber with a seven-pin number would be called, then the call would be sent over the wire (c) to the subscriber with a six-digit HOMiepoM.

In this circuit, the adjustment: the relay must be such that the PP 16 relay is activated after the PC 7 relay; however, if such an adjustment was violated, then the correctness of the system's operation should not change.

This is explained by the fact that after the PP relay triggered; 16 the circuit of the PC 7 relay does not break immediately. To break its circuit, after the relay PP 16 has been triggered, first release the relay PP 8, then PR 2 should transfer the brushes to the 11th position and, finally, the relay PP 15-P should work.

The time interval from the operation of the relay PP 16 to the breaking of the circuit of the relay PC 7 is sufficient for the latter to also be able to work.

When the TLS current distributor moves the brushes to the second position, the PC 7 relay will be disconnected from the wire (a), but it will remain blocked until PC 1 releases the CBoiero core when the drug returns to its original position.

Since the PP 15-II already in the transition of the PR 2 brushes to the 12th position is in the normal state, this means that with the register returning to the initial position, the register scheme will be ready to establish a connection with the subscriber having either six or seven numbers .

With the return of the occupied LAN, it can again be occupied to establish a connection to one or another subscriber.

It follows from the above description that the solution to the task of making a call to a seven-digit subscriber connected to one string line together with a subscriber having a six-digit number reduces to registering this registration with a minus for a certain contact PR 2 when registering a seven-digit number. which is what the PP 13 relay does.

It follows from this that in the register of the telepathic telephone table B of a telephonist who connects to long-distance calls and who is unable to register more than four characters (which is enough for a six-digit number), it would be necessary to add a relay that would trigger in appropriate cases the same role as the relay PP 13 in the case exploded.

In order to adapt the registers of the keyboard, it is proposed to add (to those indicated earlier in the description of the city register) :) another PP 13 relay and to it the button A.

The scheme of the necessary connections in the registry of the registry is shown in FIG. 2

In contrast to the considered register scheme, here PR 2-D-5 is connected to the winding PP 15-I. A second contact spring of the relay PP 13 is connected to the PR 2-C-4. Contact (a) of relay PP16 is connected to PR 2-F 4 The contact spring of relay PP 16 is connected to the winding of relay PP8.

The third contact spring of the relay PP 13 remains unused, which is explained by the fact that in PR 2 "a de A in this, there is a minus register. The other compounds in regisgr remain the same as in the pawee case.

The circuit structures in CLA1 essentially remain the same as previously described. The difference is that in the long-distance TLS it is not possible to use the contacts L-1 and here Tle-M-1 is used to turn on the PC 7 relay and conduct (a). The second difference is that the wires from the contacts in PC 7-a, (d) and PC 7-b, (c), due to the characteristics of sending the ringing current from the long-distance call, are connected to contacts PC 5-b and PC 5-g .

If a long-distance call is to be received by a subscriber with a six-digit number, the connection is made in the usual order.

The telephonist dials the required four-digit number on the keyboard. When a long-distance call arrives at the subscriber’s double-up with seven-digit number B, the telephone operator briefly presses button A and then dials a four-digit number on the keyboard.

By pressing button A, the circuit closes:

8. Minus, button A, PP 13, ICR-a, plus.

The PP 13 relay is activated and locked in the circuit:

9. Mshus, RR 13-a, RR 13, ICR-a, plus.

further, the compounds will proceed generally in the same sequence as described earlier. Just as in the previous case, PR 2 was delayed in the tenth position, it will be delayed in the fourth position.

In the presence of the circuit of FIG. Two further explanations are not required.

Adding two relays РР 15 and РР 16 to registers and PC 7 to current distributors should not be difficult, and the first one can in some cases be placed in free places with other

relays, and where this is, in the absence of space, it cannot be done, they can be collected for a whole cabinet of registers on one board and placed in a suitable

.places
