The disadvantages of the known device include:

- low noise immunity of the information channel used to transmit the cable core number, which is the cause of errors during dialing;

- fixed at the hardware level, the algorithm for deciphering the core number excluding the use of noise-protected codes;

- the lack of the ability to adjust the level of electrical signals to the electrical parameters of the cable being called and the environmental conditions in which the dial-up is performed;

- lack of voice notification of the results of calls.

Also known is a “Device for wire passing multicore cables” containing a power supply, a control unit, an indication unit, a wire number decoder and a cable connector (RF patent No. 83851, G01R 31/00, priority December 18, 2008, published on June 20, 2009 Bull. No. 17).

The disadvantages of this device are:

- fixed at the hardware level, the algorithm for deciphering the core number excluding the use of noise-protected codes;

- the impossibility of adjusting the level of electrical signals to the electrical parameters of the cable to be dialed and the environmental conditions in which the dialing is performed;

- lack of voice notification of the results of calls.

The closest in technical essence and the achieved effect to the proposed utility model is “Indicator (receiver) of the device for cable calls”, containing a power supply unit, a control unit, a wire number decoder, an indication unit, a cable connector, a comparator and a threshold voltage adjustment unit ( RF patent No. 180728, G01R 31/02, priority December 13, 2017, published on June 20, 2018 Bull. No. 18).

The disadvantages of this device, taken as a prototype, are:

- lack of voice notification of the results of calls.

The purpose of the claimed utility model is to expand the functionality of the device by verbal notification of the results of cable diving.

To achieve the specified technical result in the indicator (receiver) of the device for cable tapping, containing a power supply, a control unit, a core number decoder, an indication unit, a cable connector, a comparator and a threshold voltage adjustment unit, the output of the power supply being connected to the input of the control unit the outputs of which are connected to the first inputs of the core number decoder, display unit, comparator and threshold voltage adjustment unit, the output of the cable connector is connected to the second input comparator

the comparator output is connected to the second input of the core number decoder, the output of which is connected to the second input of the threshold voltage adjustment unit, and the output of the threshold voltage adjustment unit is connected to the third input of the comparator, the display unit is made in the form of an indication and voice notification unit.

In FIG. 1 shows a block diagram of the proposed utility model, consisting of a power supply unit 1, a control unit 2, a wire number decoder 3, an indication and voice notification unit 4, a cable connector 5, a comparator 6 and a threshold voltage adjustment unit 7.

The device operates as follows.

The device is turned on by pressing a button on the control unit 2, which leads to a supply voltage from the power supply unit 1 to the first inputs of the decoder of the core number 3, the indicating and voice notification unit 4, the comparator 6 and the threshold voltage adjustment unit 7. The core whose number you want to determine and also an additional arbitrary core of the cable, which serves as a common wire, is connected to the connector for connecting cable 5, through which they are connected to the second input of the comparator 6. At the third input of the comparator 6, from the fine tuning unit new voltage 7, the threshold voltage. The comparator 6 compares the threshold voltage with the voltage in the core, the number of which you want to determine. The result of the comparison in the form of a logical zero or a logical unit is transmitted to the second input of the decoder of the core number 3. The decoder of the core number 3, receiving from the comparator 6 a sequence of logical zeros and ones, interprets it as a combination of an interference-proof code and performs its decoding. The decoding result is the number of the core, which is transmitted to the second input of the display unit and voice notification 4 for display on the screen and simultaneous voice notification. If errors are detected in the code of the core number, the decoder of the core number 3 generates an error signal, which is transmitted to the second input of the threshold voltage adjustment unit 7. According to this signal, the threshold voltage adjustment unit 7 changes the threshold voltage supplied to the third input of the comparator 6, thereby affecting comparison result.

Using the proposed utility model allows you to expand the functionality of the device due to the voice of the notification of the result of the cable dials.
