Description

The proposed relay register scheme is designed for the ATX system with an Erikson machine-driven system with a capacity of 10,000 omers and is intended for an intermediate regional station.

In order to have a radial-serial communication between the PBX and two-wire connecting lines between them, the register scheme provides for the transfer of the entire number dialed by the subscriber to the other PBX register, as a result of which one PBX will be in the same dependency as the other has a subscriber in relation to his PBX. The total distance between subscribers in this case is limited only by the attenuation of the line for the conversational flow, since the number pulses are transmitted to the intermediate PBXs and, moreover, since the station devices are controlled by the register of the same station, the potential difference of the earth does not clearly influence to work appliances.

The relay register scheme provides for an increase in the total capacity of the telephone network to one hundred thousand numbers, therefore, the subscriber number is assumed to be five-digit. To simplify the scheme, the numbering of the GW, LAN and IWPs (Figs. 16, 17, 18) is changed, and for the start of the count, not zero is taken, as it was in the previous schemes, but one that matches the numbering on the dialer. If it is desirable to preserve the beginning of the account with zero, then zero should be made a number on the dialer in the subscriber devices. Since the largest possible number of units in a figure is nine, for |

(347)

various combinations for registering the subscriber's sign the required number of contacts

and, therefore, the relay will be determined by the formula;

t an

where m is the required number of combinations, a is the number of the device's positions, and n is the required number of devices.

For: 1 of our case m 10

therefore 10 2.

To logarithmir, we get that Ig 10 Ig 2

whence 11 - -Q-30J 3.33.

Since the 3.38 relay cannot be obtained, the nearest large number must be taken. In our case, it is necessary to take four relays. So, in order to obtain ten different combinations, four relays are needed, which corresponds to the diagrams of recording kits (Fig. 5, 6, 7, and 9).

A characteristic feature of this relay register scheme is that the set of digits is marked by a successive break in the control circuit, according to the number of units in the dialed digit, and the movement control of the instruments is carried out by sequential restoration of the same control circuit.

In the attached drawing, FIGS. 1, 2, 3, 4, 5,

b, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17 and 18 depict a diagram of a device according to the invention.

FIG. 2 schematically shows the control circuit, where the contacts a, b. c, d relate to the contacts of the relay registering numbers. and the contacts e, z, z, k-contacts are re, the control of the two devices in the devices.

The TiiM in FIG. 2 shows a graphical pabod of relays (contacts) recording the number sign.

When the impulse relay P (Fig. 3) is turned on and triggered, the circuit closes:

15. Cpus aP8-6Pi-aPs-P4-minus. Relay P4 will work.

The impulse digit 3 is registered and the PS relay will release the measles.

When registering the digit 3, Re and P7 almost do not participate, but they lengthen the PI relay four times. The extension of pulses is necessary because each relay RP Pie and

PIP and Hi combination must mark two units: odd and even, and the relay Pie works with each unit, which complements the work of the other relays.

When the relay relays release the measles, a circuit is formed:

16. Plus BRa-aP -7-ePn -Pig-misch. Relay Pi2 is activated, is blocked by contact e and turns on the relay registering the second digit of the number.

The PH relay will release the switch and disable the relay registering the first Digit.

The P45 relay will work, „the circuit of the p44 will be interrupted which will ornvcTHT the measles and this will break the circuit, the relay Rzv-Relay Rze will release the measles and break the circuit of the relay РЗЪ which will also release and disconnect the control set from the second register.

At the same time, a chain is formed:

30.Plus - rTb - vRto- 106-6P4B-95-P4-minus. Relay P4i will operate and connect a fourth set of recording relays to control the circular movement of the linear connector. If the subscriber has not dialed the P1-toll station, then the relay will remain in.

A chain forms:

31.Plus - rPi4 - 36-bP45-108-bva-Pb9 minus.

If the subscriber dialed the fourth digit of the number, then the PU relay will not be in operation, circuit 31 will not be closed, and relay Re will release the measles. The Re relay will close the Reye relay circuit, therefore, the register will be prepared for receiving reverse circular motion pulses of the linear connector.

When the group selector finds a free linear connector, the Rez relay will work and the Pb7 relay will receive reverse pulses of circular movement of the linear connector along circuit 24:

Since the fourth character is O, the linear connector must be stopped against the 15th frame of the even pin.

At the first impulse the relay Рщ. A chain forms:

If the subscriber did not dial the fifth character, then the relay Рб9. Will stop working.

37.By chain: plus-gPi-37-bP4v-108-bpm-Ree-minus.

When the customer picks up the fifth character, the relay will release the measles, and the Peg relay will work.

The linear connector rail will enter the 15th frame, in which it must be stopped against the 17th string.

The first th pulses will not produce any action, since the control circuit is interrupted by a contact in the relay P. which will be in operation.

When the 11th pulse is received, the Ruz relay will operate, block and contact G will partially restore the control circuit.

After receiving the 17th pulse, a circuit is formed:

38.Pydyus-GR, B-106-BR4o-104-114-ГРв8- 72-вР2з-73 - ГР4e - 101 - BР5-100-ВР40-79-Bpa4-BPs9 - BRS - 76-Br. -97-brb7-rb9-minus.

Relay P (59 will work, break the Peg circuit and thereby stop the linear connector rail against the 17th string.

The instruments are installed, the register is finished, and the register must be turned off, therefore the signal must be out of the register.

After the Peg relay is activated and the RES RES is released, a circuit is formed.

39.Plus-gP7v-in P70-aP71-109-gP4v-P47-minus. Relay P47 will work.

40.Plus-rR7v-106-6P47-2 and tokoraspr1 divider call finder. This hangs up and the register is disconnected.

Connected by a subscriber to another local telephone exchange.

As indicated at the beginning, for this, in order to have radial-to-serial communication of district PBXs with two-wire interconnecting lines, this relay register circuit provides for the transfer of the entire number to another PBX register.

As a result, the work of a legionary of a district PBX, when connected to a subscriber of another district station, will consist in determining the direction of the connection and in transmitting the number.

The possibility of transferring a subscriber number from one PBX to another, besides the advantages already noted, makes communication between district telephone exchanges of various systems extremely simple and allows the PBX system of a stepping system to be directly connected to a machine-driven PBX.

The connecting line pattern is also greatly simplified in this way and can represent a slightly modified line pattern of the subscriber MB, although the way the connecting lines are turned on depends on the graph.

Fng. 14 is a two-way linking circuit, and FIG. 15-diagram of the connecting line of one-way dataphone - inbound and outbound

In view of the fact that the existing station equipment schemes are designed: there are three-wire connecting lines between them, and connecting line schemes are two-wire, in order not to disrupt the test relays, it is necessary to turn on the strings from the connecting lines and pass minus batteries on a string with.

However, in the schemes of the station devices, it is necessary to carry out this circumstance and do not test the breakdown of the presence of the battery plus, as is the case in the existing schemes, but there is no polarity at all, then minus the batteries through the cf resistance. strings with connecting lines would not be necessary.

Supposedly, the subscriber dials the number 70161, which corresponds to the subscriber number, FIG. 1, and, therefore, the United should go through the IV and VI PBX.

Number registration is performed in the same way as in the case of connection with the subscriber of the same station.

Connecting lines to IV PBX and I1 PBX are included in the 22nd frame of the group-elector and, therefore, the rail must be installed against the 22nd frame; i.e. the movement of the groups of electors should cease after 22 pulses.

The first 20 pulses will not produce any action, since the control circuit will be interrupted by a contact psa of the Psa relay and the contacts of the RIOT relay of the 20th pulse will activate Psa and block. A chain forms:

41.Plus-bP44-36-bp (d-minus.

When the rake group voted will fit1. to the 22nd frame and the control set of the relay I will be given the following two pulses, then arr; 1 t I of the circuit:

42.P | yus rPie -DR18-47-вРо4-rPca-liePve-minus.

Relay Rte will work, interrupt the DOV relay circuit and this will stop the group selector rail against the 22nd frame.

Relay h; 1b.1 (1kiruets. Formed circuit:

43.Plus BRa 8-bR o-vtb-Pve-minus. When the gambler finds a free

link; 1 line, then a chain is formed:

44. Inductor-P78-bR75-aP7v-120-line bPa (F 1G. 1.5) -PI-capacitor-line -121-bGHG -Pir, -RTZ inductor.

Role PIS works simultaneously with the linear village PI (Fig. 15) and forms a chain:

45. Plus-aR7z-R7b-minus.

Re i; P75 will work, interrupt the inductor current circuit and turn on the winding of the relay P74 in line.

When connecting devices IV PBX are ready to receive pulses 11 PBXs, then relay 74 will operate in series with the pulse relay of register IV PBXs through the line and for 6.1 it operates. A chain forms:

46. P, us - BRZ-8-6R70-BP75 -GR75-DR74- P74minus,

It closes for a short line through the contact of the pulse relay P78. A chain forms:

47. Wiring-120-BR7e-aP74-121 and switching relays P77 and P78. A chain is then formed:

48.Plus usus-P77-6P74-aP7o-aRooe-Rv8-mine with. Relay ROSES and P77 cf.

Relay P77 closes the circuit:

49.Plus-a77 P78-minus.

Relay P78 will work, will ground Relay P77 with contact O, interrupt the circuit of the pulse relay of the IV ATS register and contact A will give a reverse pulse to the relay Pb7.

Relay P77 release: 1T measles and break the chain relap P78) Which taK.ice will release the measles.

Relay P77 will work again, will close the P7v circuit which will again punch off the P77, etc.

Since the relay P7c switches the contacts g, then the relay P71, P7a. P44 and P4j release measles and, therefore, the number dialed by the subscriber will be before: n on the IV PBX all, including the first digit.

The work of the control set will be the same as when receiving the return pulses from the searchers.

Relay Рв4 in this case will be all the time in the work of depi:

50.PLYUG, -GR74-P70 and Rv4-minus.

Consequently, the reverse pulses will be lengthened with the help of the Rvb and Rhey relays, which is necessary, since each unit consists of „break of impulses”.

From the IV PBX number will be transferred in the same way to the VI PBX and from VI to VII, where the connection will be given.

This register scheme also has the advantage that the registration of the number does not require the constancy of the speed of the pulses and, as a result, dialing speed control can be used.

Subject matter.

A relay register for automatic telephone stations, characterized in that with the aim of cooperating with the subscriber devices having dialers without a speed controller, high-speed polarized relays Pj, n P- are included in the register so that reduce the speed of received pulses, and so that the registration of the pulses of the subscriber's number is carried out by the opening of the control circuit, the registration of the return pulses sent during the movement of the searchers is made by closing to control circuit, the control circuit of the register contacts a, b, c, d relays registering the number sign, and contacts e, f, h, and the relay controlling the position of 1 Skatelity are turned on so that the current circuit can sequentially pass through the contacts of different steps formed by mutually shunting contacts b, zk, respectively, c, s; and, g, etc.
