SUBSCRIBER DEVICE FOR ACCOUNTING TIME. WATER BODY: .GY Razotorob The field of technology to which the utility model relates

The utility model relates to telephony and can be used to take into account the subscriber's time as the current conversation, and the total time of calls for any period.

State of the art

In order to ensure that the subscriber takes into account the duration (cost) of telephone conversations, it is proposed that a number of devices are operated, and these devices can be built into telephones, connected to them, or have an independent design that connects directly to the subscriber line. It should be noted that the previously proposed devices , which provide direct accounting of the cost of the television calls made, have now lost their relevance due to the volatility of the level of telephone tariffs. In Slovenia, time recording of telephone conversations becomes preferable, although the choice of accounting form for the technical implementation of the devices in question is not fundamental. In general, these devices, depending on the accounting form, contain an account initiating unit that defines the generator. Counters and an indicator that reflects the counting results

One examples of such a device that is closest in terms of the totality of features to the proposed utility model is the invention according to the copyright certificate of $ 171107333 A, 07/07/84, which contains the dialer of the dialed number, one of the punctures of which is to set the reference point (after the end of dialing the number in the line by the subscriber) to start the master oscillator, the converted pulses from which are counted by series-connected counters. the cost of p rgoEor and the current cost of the conversation, the latter being included in the display unit, which, in turn, will open one hundred M.cl.6: Н041Л 15/30

Pmost current conversation or (with appropriate manual inclusion)

total cost of telephone calls.

However, the use of the device E in question at present can cause certain difficulties for the consumer due to not only changes in the tariff policy of telephone service providers, but also :: changes in the form of recording telephone conversations, namely the introduction of constant and variable components of this accounting. Option: payment is made in the form of a fixed monthly fee for the accounting period (: month) and, in the event of a cost overrun of a predetermined time limit for telephone calls for the accounting period, additional payment In addition, the device in question is intended to work as part of a subscriber telephone installation (which follows from the name of the invention) and is not intended to be directly connected to the line, however, this drawback is easily eliminated by introducing an appropriate interface, for example, in the invention according to the copyright certificate SUI2856I8 AI, 01/23/87

Utility Model Essence

The purpose of the proposed utility model is to update and expand the consumer properties of subscriber units for recording telephone conversations by introducing, in addition to the well-known Form for recording telephone conversations by means of a direct (summing) account, also by taking into account the total duration of telephone conversations by means of a return (subtracting) account from the corresponding preliminary setting the initial values.

To accomplish this task, a well-known diagram of the telephone call duration (cost) metering device is used, which contains an interface connected to the subscriber line, a power supply unit, a communication type analyzer, a generator, current and total call time counters, and an indication unit, supplemented by a pre-installation unit, connected :: wit with a total time counter p; zgoyurov, and the latter, in turn, is performed with a changed structure - according to the scheme of a reversible counter with preset.

Information confirming the feasibility of implementing a utility model

The subscriber telephone time metering device, according to the drawing, comprises an interface I connected to the subscriber’s terminal, the outputs of which are connected to the power supply unit 2 and to the communication analyzer 3, respectively, while the output of the analyzer 3 is connected to the control

about.

the input of the master 4 generator, the output of which is connected in parallel

to the counting inputs of the counter 5 of the current talk time to the counter 6 of the total talk time, respectively, while the information output of the counter 5 and the first and second information outputs of the counter 6 are connected to the corresponding inputs of the unit 7 igjkgdni. In addition, the device contains a preset unit 8 connected to installation input of the counter 6.

The device operates as follows. After connecting the device to the subscriber line, voltage from the liquor is supplied to the power supply unit 2 through interface I. The power supply unit 2, tactically is a secondary power source, is constructed, for example, according to the typical circuit of telephone sets power supplies (current stabilizer and zener diode), which allows you to get the necessary voltage to power the energy-consuming units of the device. When the handset is placed on the subscriber’s device, device activation does not occur due to the lack of necessary signals The output voltage of the analyzer ZL when the subscriber lifts the handset of the E line, the Voltage level changes sharply, which is perceived through interface I with torus 3, which then emits a signal. For installation E, the initial state of the current generator 4 and counter 5 (the latter receives a signal through the generator 4 ). Moreover, the counter 6, which was connected in parallel at the inputs with counter 5, did not receive the indicated signal, due to the corresponding construction of the input circuits in counter 6 (selection of the frequency or duration of the signal). By the number B line, analyzer 3 generates a start signal that activates the master 4 generator, the impulses appearing at the input of which are received by counters 5 and 6 at the same time, with subsequent reflection of the count results in the indication block 7. Thus, counter 6 of the total talk time works as a counter only after the nchborz of the number with a bonect, at the intervals between the outgoing calls of the subscriber, he performs the puncture of the register for storing the accumulated information.

pulses, i BYUZh pulled by the master 4 generator (i.e., shift units, 2 of which are being kept records), are selected as the most convenient for the consumer, for example, I minute, as the most used unit for recording telephone calls, In case the subscriber doesn’t dial the number after picking up the handset, analyzer 3 perceives this fact as an incoming connection, the start signal is not generated, the activation of the master 4 generators, counters 5 and 6 is performed “Thus, the accounting of the time of telephone calls shakes only with outgoing communication after dialing the number, line g stops when the handset is placed on the device. Moreover, if the current talk time is counted in counter 5 by a direct calculation using the usual scheme, then the mode for taking into account the total time between calls in counter 6 depends on the preliminary setting of this consumer counter. In the general case, at the beginning of the accounting period (for example, a calendar month), the subscriber sets the counter b to its original position, by entering a specific digital value into it through block 8 of the preset, kek pr There is a corresponding limit on the duration of calls to be paid within the framework of a fixed subscription fee. In this case, the connection of counter 6 to the display unit provides the subscriber with control of the set values. The preset unit 8 in the simplest case can consist of one or two buttons, by successive pressing of which the subscriber enters the necessary digital value into the counter 6. If necessary, the preset unit 8 can be powered from the power circuits of the counter 6. At the time of installation of the counter 6, it is automatically installed into the subtraction mode, i.e., each impulse coming in later on to its counting input decreases the value at its output by one. Thus, after the device is pre-installed on block 7 and where outgoing calls will reflect the time of the current conversation in a direct account (cumulative), and the total time of conversations in the opposite

, -5 not subject to additional payment. For the accounting period.

In case the actual total talk time exceeds the set value, i.e. the reversible counter 6 will go through a zero value, it will automatically switch to direct counting mode and the display unit 7 will begin to show, starting from a zero value, the time to be paid additionally. Thus, the subscriber receives operational information about the overrun of the time limit and the value of this overspending on an accrual basis, including at the end of the accounting period. To constantly inform the user about the operating mode of counter b (reverse or direct count), this counter produces a special a signal during the entire period of operation of one of the modes (mainly the mode in which the time wasted is counted), which goes to the display unit 7 and is reflected there. Considering that the display unit 7 is constructed, as a rule, on the basis of digitally-sign liquid crystal indicators (minimum energy consumption), the signal can be reflected in an easily recognizable symbol, such as a watch with a dial.

In special cases, the user can set any digital value, based on various criteria, limited only by the number of bits E of the display unit 7, including zero. In the latter case, the counter 6 will only work in direct counting mode.

The total talk time counter 6 can be built on standard microcircuits, mainly manufactured using CMOS technology (low energy consumption), in particular, reverse meters with a preliminary installation of K561IEP, etc., which greatly simplifies the implementation of the utility model.

The use of the proposed utility model, which is universal in nature, will expand the consumer properties of subscriber devices for recording the duration of telephone conversations and increase the convenience when using them.
