Telephone equipment tariffication ^jj: Y '

Technical field

The technical solution relates to a telephone tariff apparatus for recording telephone call data, in particular for public telephone booths.

BACKGROUND OF THE INVENTION kHz which device, kd

Devices of various types are used to record data about a telephone call made as a basis for establishing a call charge. Apart from manual switching of the line to the subscriber telephone sets with manual recording of the call duration, mechanical counters of frequency control pulses are used. It is very simple it is necessary to manually record individual stsvy counters and keep separate accounts, the subscriber does not have an ongoing overview of the cost of the call, everything puts great demands on operator activity. This solution is supplemented by a device with automatic recording of the number of pulses for each connected telephone. Here too, it is necessary to monitor the current statuses, if they are not always the same participant, all activity is subject to the cooperation of the operator. There is also known a device for switching calls at telephone counters, especially at post offices. This device is equipped with total telephone length indicators. call directly in price, relations, both for the operator and the customer for inspection directly in the cab. The device comprises a switching unit by which the public network line is switched to individual customers, a signaling unit, a co-monitoring unit that enables the operator to answer calls to the customer's accounts.

istreone, preoani \ ^t cru; ; unit also prevent ^- incorrect handling. Furthermore, the known device is equipped with a blocking device which does not allow further dialing on a busy line where the call charges have not yet been paid to both the operator and the customer. Only the operator can cancel the blocking. It is possible to connect both normal and automatic calls. The device is also equipped with a spare power supply. Even here, however, the operator only has the number of tariff pulses, must manually reset the counter, and to calculate the call must know the initial and final state of the counter. If the customer does not receive the connection, he must ask the operator for a new dialing authorization. The disadvantage for the customer is the possibility of tapping his call by the operator. Moreover, he has an overview of the number of tariff impulses during the call, not the actual price. This must be calculated manually by the operator.

A completely different category then includes separate coin and telephone card machines. You can call anywhere, but you must have either a sufficient supply of coins or a phone card with the required capacity. The unit does not return unpaid amounts.

The essence of the technical solution

A telephone billing device for a telephone call, which comprises recording a telephone call, in particular having its first port on the control memory, a second port on the traffic data memory, and a third port over the first communication circuit to the control block, and input to the real circuit at least one line unit with a circuit of numbers. The control unit is provided with a fourth port to which a second communication circuit is connected for connecting peripheral devices. The line unit is equipped with a tariff pulse reception circuit, the output of which is led to a second input controlling the control block is provided with a keyboard with a display. Time management and second input for telephone call analysis • The unit for public is equipped with a control unit, all of which are connected to the data bus of this processor.

The device offers simple operation of individual functions, great informative ability of call data that has been recorded, enables further processing of the obtained data, fast operation with the participation of a customer who can select the desired connection, which facilitates operation and saves customer time . It is also possible to set various parameters and thus affect traffic on selected lines. The device is also able to monitor two devices on one line and keep a separate account for each device. All accounting operations are carried out automatically without any further operator involvement.

BRIEF DESCRIPTION OF THE DRAWINGS

The technical solution will be further elucidated in more detail on the examples of its practical implementation, which are shown in the attached drawing, in which a basic block diagram of one line and two telephone sets is drawn.

Exemplary embodiment

The telephone billing device for recording telephone call data as shown in the drawing consists of a control unit 1, a control memory 2 connected to the first port 11 of the control unit 1, a traffic data memory 3 connected to the second port 12 of the control unit X, the control 5 is connected to the third port 13 of the control unit 1 and the second communication circuit X connected to the fourth port 14 of the control unit χ. This second communication circuit 6 serves to connect peripheral devices 7, such as a computer 71, a traffic data printer 72, a customer display 4, or a traffic data transmission modem 73, and is an additional circuit that is not an essential part of the circuit. The device is further provided with a real-time circuit 8 connected to the first input 15 of the control unit 1 and a line unit 9 equipped with a telephone number analysis circuit 91. This circuit has an output coupled to a third input 17 of the control unit 1. The line unit 9 is further provided with a circuit 92 of reception pulses transmitted usually as 16 kHz AC pulses or as DC pulses. The output of this circuit is fed to the second input 16 of the control unit 1. The tariff pulse reception circuit 92 is also a circuit that is used only where a tariff pulse is transmitted to the telephone network.

The control unit 1 is equipped with a processor, its type and type is not essential, it is sufficient eight bit. 'All inputs and ports are connected to the data bus of this processor.

The telephone number analysis circuit 91 to analyze the pulse, frequency, or other dialing may be connected to the telephone line either in parallel. This allows you to detect and record even the tracked line.

who is capable of phone number, serioparalelnš or calls unauthorized

Device for recording the number and forwards it to the control unit l

The control unit 1 compares and, if found, evaluates it as valid and assigns additional information to it. According to the data from the call, the time / memory 2 and the real-time circuit 8 are initially assembled and displayed on the displays 52, 74. Then the tariff pulses are 16 kHz and based on these data the call rate is determined. The second communication circuit 6 permits data transmission not only to the customer display 74, but especially for further processing and evaluation.

The custom phonebook is a prohibited number, which devices block such numbers no call.

can be used for starting: and will not allow to do it

The whole device can operate in essentially three modes: pseudotarification mode, 16 kHz tariff pulse tariff mode or DC link pulse tariff mode. In the case of pseudotarification, the device evaluates the dialing number, measures the call duration, and calculates the cost per call based on the tariff map data provided with the software. The selected mark-up is automatically added and the data is displayed on the displays 52. 74 and a receipt is printed on the connected printer 72. There is a similar procedure in tariff pulse mode, but the price is based on the number of pulses recorded. It is so-called exact tariffication. Even more precisely is the tariff tariff system using direct tariff pulses, which almost eliminates errors. All call information is stored in memory

3. operating data that is backed up against data loss in the event of a power failure.

As mentioned above, the device is adapted to the operating conditions so that it is possible first to operate in pseudo-tariff mode based on time and later when the transmitter has been installed on the line to switch to exact tariffication.

or telephone sets 93, unit 9. and likewise the number of these line units 9 connected to the control unit 1 is influenced by the type of processor used and the capacity of the individual service blocks and circuits of 16 kHz, lines,

Similarly, the number of telephone connections per line and the size connected to the control unit 1.

Industrial applicability

The telephone tariff system is intended for public telephone booths, especially at post offices. It can also be used in hotels, restaurants, guest houses, dormitories, railway stations, hospitals, industrial and commercial enterprises, etc.
