Description

I

This invention relates to telephony and the moket is used: In automatic dialing devices.

By ocHpBHtMMy auth. St. Ni 6О6226 is known to an automatic dialer containing a matrix, a selector unit, a sequential polling unit, a code converter and the corresponding connections. With Ohanako, the known dialer has a relatively low maximum value of the dialed numbers.

The purpose of the invention is to increase the maximum value of dialed numbers.

This is introduced into the well-known dialer by a sequential-write unit and a fixation block of the selector circuit. The outputs of the selection block are connected through the fixation block of the selector circuit to the information inputs of the matrix, whose output outputs are connected to the corresponding inputs of the sequential write block, whose output to the corresponding input b while the the poll corresponding to the output of which is connected to the first auxiliary input of the sequential recording unit, the second additional signal which is connected to additional output block selection.

The drawing shows a structural electrical circuit of the proposed dialer.

The automatic dialer contains a matrix 1, a block 2 of sequential recording, a block 3 of sequential interrogation, a block 4 of fixing the selection circuit, a code converter 5 and a block 6 of selection.

Automatic dialer.

15 works as follows.

When you press the button for a personalized tattoo (not shown in the drawing), block 6 generates a signal B at a certain output, block 4, which captures a certain

20 chain of entry. After that, a pulse is fed to the second auxiliary input of block 2. This pulse gives permission for the pro- duction of the recording pulse through the first copy provanic of matrix 1 and the first input of block 2.

The impulse translates into one state those of the cores of matrix 1, through which the first coding conductor is stitched. At the same time, block 2 prepares to write to the second input and outputs a signal to block 3. This signal sets block 3 to read the information from the first bit of the matrix 1. The read pulse returns the cores of the first bit of the matrix 1 to the initial zero state. In this case, a combination of pulses is supplied to the inputs of the code converter 5, corresponding to: 1 digit encoded in the matrix of the matrix. Code converter 5 converts the received information into a sequence of pulses corresponding to a coded digit, and outputs this sequence of pulses to the output to the subscriber line. After testing a series of pulses, the code converter 5 outputs a signal for connecting a conversational circuit (not shown) and counts the inter-pause, after which the conversation circuit is disconnected, and the code 3 is sent to block 3 for polling the next bit, resulting in the reading of the second digit.

Thus, sequential reading of all bits of the matrix 1 occurs. If the next bit is empty, then the set is stopped and turned off.

At the moment of reading the last bit, a pulse is sent to the first additional input of unit 2, destroying

recording on the second coding conductor and the second input of block 2. At the time of recording, a signal appears at the output of block 2, setting block 3 to the position of reading the first bit of the matrix. Further, the operation proceeds as described above.

The proposed automatic dialer provides a programmed set of multi-digit numbers, which allows to increase the speed of dialing.
