Description

, l eiyraraeMQ / relates to the field of telephone communication, mainly to collective subscriber lines and can be used to carry out telephone communications through a single device. The problem addressed by m / & / m m is to simplify existing telephone communication schemes, for example, by means of a switch or coyapeater, in which the use of logical elements for automatic connection or disconnection of subscribers leads to unnecessarily cumbersome devices without a corresponding extension fraschionalnnh their capabilities. A device for communicating is known, for example, a telephone path telephone clerk / cm. Technical Description L. TS /, housing, electrical circuit, consist of a separate dialer and a telephone receiver. The disadvantage of the well-known entratot is that it is young, due to the presence, for example, of separate identical cards for direct and automatic telephone exchanges / PBX /, for example, each card can connect a card with one of the logical logic elements in the electric circuit, and is able to complete a complete operation communication with this or that subscriber. In other words, the circuit design of the concentrator vrvdshshsgavt is a multiplicity of duplicating elements, which is non-consummate “arivodyag to its rise in price. There are also drawbacks to using a concentrate atom. For example, the call signal of a water subscriber only if you press and hold the button pressed, poor-quality audibility in your hands, conferencing to work with ATb subscribers, non-silence of disconnection during a conversation of one subscriber / general reset required /; in the event of a power outage, the telephone exchange is turned off. t h It is also known a telephone communication device, an on-line telephone Llur-201 telephone, a housing, an electric telephone day with a working place / a telephone dialer, a telephone filter and a call in front of the PBX / ohm line. E.VDubrovskmy, Handbook of a young telephone operator, M, Vyoshaya shkola, 1991, p.93-96, Fig. 79 /, The disadvantage of this device for making telephone communications is the limited ability of the telephone / telephone to make collective communication. This known device is closest in technical essence to the proposed solution since the blocks of its electric circuit, in particular the presence of a matching filter, most satisfy the conditions of the task. This is a telephone prototype. The specific task solved by MLEZYMMO & Elys is to create a compact system of collective communication based on electricity: using a regular telephone to use the achieved quality of listening to a conversation, as well as to eliminate when using those shortcomings that are present, our number, and the connection rate TS. The strength of the solution is that a known telephone communication device comprising an electric circuit of a telephone with a workstation / dialer, telephone handset /, matching filter and a bell in front of the PBX line, for connecting direct calls to @ в. it is equipped with ./shared / one / control-szvozhnoy device, additional call / for direct subscribers / and power supply, and the output is connected to the electric bus between the workstation and the agreed-upon. “Злз, с ..г :, in particular, it has a dvlshvrn switch, a light indicator, for example, even a subscriber, a subscriber relay, one of which can be installed without any charge I /

it is one with the control and ringing device. In addition, in the known device between the bell, matching filter and the PBX line there is a two-pair switch, the movable contacts of which are connected to the PBX line, and the fixed ones, one with the bell, the others with matching

filter.

from other sources of information and audio devices for telephone communication, having good quality of listening to a conversation, appiader, commutator of gardaigorsk communication and others

However, due to their circuit solutions, these devices are block-oriented for each subscriber. They occupy large volumes and are not acceptable for the task at hand.

The technical result of the proposed solution, as a result of the combination of the signs stated above, is expressed in the fact that one control and ringing device provided the necessary telephone connection for direct subscribers if each of them had a relatively simple touch-sensitive device. In addition to connecting to an additional PBX subscriber, through the two-paired switch, the proposed ол ол ство п ство конф конф конф конф ерев ерев ерев ерев 1 для для для for subscribers of automatic telephone exchanges

At the same time, the use of a two-pair switch in a communal housing allows, on the one hand, not to make a button wrench

That call to the direct subscriber, on the other hand, to disconnect from the direct subscriber without putting such a mess in others.

The inventive step of the previous solution lies in the fact that the direction was chosen to ezdmgii general control and ringing device that performs the function of calling subscribers, coordinating their work, monitoring the signal 9 LSPN, and the apparent inconvenience of using a two-pair switch was in favor, I rely on much greater autonomy of each subscriber. The essence of the awesome Model is lurking, which shows the electric circuit of a device for telephone communications.

b // ac /: c / i iA / y / ri 7t $ t / ts, showing & Unsheptede, for subscriber 4 is in the director’s extras position, switch Id is in the upper position, group of contacts 16 is switched to workstation I.

 / 4/4/7 $ qt / ts j shown on the drawing, for subscriber 5 is in the newest call of the direct subscriber, switch II is in the lower position, the pear of contacts 11 is switched to the call control device Id

A call is a conversation - the conversation takes place as the next subscriber happens next time, DIRECT subscriber 4 picks up the telephone, its circuit goes on, 1G rings, and indicator 1, relay 14, contacts 16 are closed, contacts 16 of which are closed to the workstation I. Director is making a call Director transfers the switch 10 is in the lower position and, thereby, closes the redundant relay circuit and, the call 19 is turned off, the indicator 12 continues to give a signal, through the telephone line of the workstation I, the call is negotiated. To stop the conversation, the direct subscriber steals “cutting, his circuit opens. The divertor transfers the latch of TVL 10 to the upper position, turns off

by the telephon 22. Indicator 12 in this case works, signaling the sneaker of neither the subscriber to enter the conversation.

A call — a conversation — a call is terminated by the director, for example, with subscriber 5, as follows. The director moves switch II to the south, digging indicator 13 control and ringing device 1-1 generates a ringing signal subscriber about. Subscriber 5 picks up the phone, thus closing the relay circuit 15, and contacts 17 to the workstation © 1 There is a conversation. Termination & accusation by the director is done by moving switch II to the top of it. Subscriber 5 must half a step grower, then disconnect relay 15 by closing contact 17 to the control-calling device Ie

Work with subscribers

In the drawing, the non-switch ° is shown in the call director 1 position, switch 9 is shown in the call or talk position.

1 To call a project, the subscriber dials the corresponding telephone number of the director, the signal goes to call 3. The director puts the pet picker in the lower position, then the conversation continues. When I switch the switch to the up position, the conversation is interrupted.

For the director to dial the subscriber’s number АЈС, for example 7, switch 0 is moved to the lower position.

Regardless of the communication at the subscriber in, the communication with the subscriber is likewise carried out, for example, when talking about the subscriber 6, the director hears a call 3 made by the subscriber 7. To stop the signal being sent, the director translate the P switch to the bottom,

then in the upper position, thus breaking off the connection with the dialer of the subscriber 7

From the above it follows that the director can be simultaneously

and selectively associated with both the direct subscriber and the automatic telephone exchange PBX, so each of the tacks can be flawed by each other. Thus, the connection is made both in the mode of kosputator, concentrator, and in conference mode. In view of the variety of forms of connection of subscribers. matching filter

Pulls over the main function of matching signals to the subscriber. ATS; eliminating interference from the ATS line.

The control and ringing device, I control the basic functions of calling a direct subscriber, monitoring signal transmission, coordinating communications, performs the function of eliminating interference from the passage of electrical noise from the power supply in the telephone

The proposed device allows you to connect the recorder through the switch between the workstation I and the filter 2 / connection is not shown in the drawing /, as well as use one of the telesrons of subscribers as a secretary's phone. The work of the secretary's phone is ensured by the fact that without the desire of a divertor, not a single subscriber did not live to connect to the conversation.

In such a way, a sufficient number of functions performed by the device for telephone communications, a small number of power points in the electric circuit, excluding their duplication, ensures its simplicity, compactness, communication / listening quality /, both autonomous and collective, as well as the possibility of mounting the entire circuit electret g phone case.
