FIG. 1 shows the structural - electrical circuit of the proposed device; in fig. 2 is a structural electrical circuit of the number selection unit; FIG. 3 is a structural electrical block diagram of the organization of the sequence of numbers.

The device or automatic connection set-up contains a time distributor 1, a memory block 2, a sign block of a statature 3, n registers of 4 numbers, n distributors 5, m blocks of a translation 6, an input switch 7, an output switch 8, m receivers 9, a matching unit channels 10, number display unit 11, number sequencing unit 12, number selection block 13, category forming unit 14, decoder 15, signaling unit 16, n service registers 17, failure analysis unit 18, failure indicator 19, m memory blocks 20 These characters, multiplexer 21.

The number selection block 3 contains a bypass counter 22, switches of priority bits 23 and 24, the address register of number 25, a turn-start key 26, a two-minute interval counter 27.

The sequence numbering unit 12 contains the control signal analyzer 28, an address counter

5 29, buffer register 30, and memory node 31 of register addresses.

The device works as follows.

When you press one of the buttons in

In Q block 3 of the sign keyboard, input and output switches 7 and 8 are started via the time distributor 1. The code of the entered character enters the display unit 11, highlighting the dialed number. In block 12 of organizing the sequence of numbers, the analyzer of control signals 28 reads through the switch 8 bits of the service register 171 and the code of the performed operation from the output of the block 3 of the sign keyboard issues a stop signal of the switches 7 and 8 on the first free register 41 and enables the distributor 51 .. Signal Record from the output of the temporary distributor 1 through the distributor 51 writes to the register 41 a code of the character coming from block 3 through the switch 7. When one of the buttons of the processing category is pressed

0 telegrams or erase buttons in the category block 14, the time distributor 1 starts the switches 7 and 8. In block 12, the control signal analyzer 28

5 reads through the switch 8 bits of register 171 and the code of the operation to be performed from the output of block 14, generates a stop signal of switches 7 and 8 on the first register 41 in the queue, enables the distributor 51 to work. Signal records from the output of the time distributor 1 through the distributor 5 writes to the register 171 the code of the category of processing, ki of the entered number, or deletes it, respectively. The display in block 11 is turned off.

The address code of registers 41 and 171, with which any operations are performed, via the decoder 15 also enters a signaling unit 16, indicating the appropriate cell for storing telegram forms and the nature of the operation to be performed.

Receiver 9J. analyzes the state

5 lines through channel interface 10. If the channel is free, the signal goes through multiplexer 21 to the time distributor 1, which starts the switches 7 and 8. The bypass counter 22 is allowed in the number selection block 13, which organizes the scan to determine the first in turn taking into account the order of input into the device and the processing category .

In this case, in block 13, the search begins within 2 minutes among the numbers in the queue after the number that was last refused to establish the connection, and then, starting from the beginning of the queue, to the next failure. If such a number is found, at the command of block 13, block 12 issues a stop signal for switches 7 and 8, allowing the distributor 51 to work. Signal Record from the output of temporary distributor 1 writes distributor 51 to register 171 to which this register will be found when interacting with this channel. The request. To the sample from the register 41 for transmission to the channel comes from the translation unit 6j to the time distributor 1 ,. triggering switch 8. It searches for the number selected for transmission on this channel, based on the sign in the corresponding channel of the register 17

Block 12 outlines the switch 8 signal of the switch 8, the sign code of the number from the register 41 through the switch 8 is recorded in the memory block of the sign 20j of the corresponding channel and transmitted through the broadcast unit 6j to the channel.

When transmitting a number with processing category B that received one failure in switch 8, the destination number is replaced with the reset number read from memory 2.

Upon receipt of a failure to establish a connection by the dialed number through one of the channels, the Failure signal through the multiplexer 21 from the output of the corresponding receiver 9j enters the failure analysis unit 18, starts the switch 8 through the time distributor 1. The search for the failed number is performed. in the corresponding register register 171. Block 18 analyzes the number of failures received by the numbers that are accessed at this time moment, and issues in the block 12 the operation code Failure allowing the formation of a stop signal and switch 8, if the number of refusals to establish a connection for a given number is less than the limit set in advance.

Unit 12 issues the stop of switch 8, enables the operation of the distributor 51.

Signal Record from time distributor 1 through distributor 51 increases in register 171 the number of connection set-up failures received by the number one.

If the number of refusals of this number is equal to the limit for this

0 processing categories in the device, the fault indicator 19 is turned on, the switch 8 is not allowed to stop the operation Failure.

By pressing the buttons Repeat or 5 Hang up on the corresponding channel, the operator allows the user to repeat attempts to establish a connection with this number or erases it. -When you press the End button on a specific channel in block 14 with a signal from the time distributor - 1 for-. switches 7 and 8 are started up. In block 12, the register 171 bits read by the switch 8 and register 171 and the operation being performed from the output of block 14 give a signal to stop switch 7 and, 8 to the corresponding register, allowing the distributor 51 to work. Signal 0 from the time distributor 1 through the distributor 51 writes O, coming from block 14 through the switch 7, into registers 41 and 171.

5 This number register is free to write a new number. In block 12, the address of this register is set to the end of the queue, and the addresses of the adjacent registers are shifted.

- When the button is pressed. The repetition of a certain channel in block 14 by a signal from the temporary switch 1 switches 7 and 8 on.

5 block 12, the analyzer of control signals 28 through the switch 8 according to the bits of the register 171 and the code of the operation being performed from the output of block 14 produces a stop signal of the switches

0 7 and 8 on the corresponding register, permits the operation of the distributor 51. Signal Record from the temporary distributor 1 through the distributor 51 writes O to bits 171,

5 storing the number of connection set-up failures received and the indication of the ownership of the register 41 to a specific channel. The channel number recorded in register 41 has dried its place in the queue, and attempts to establish a connection on it will be repeated.

The proposed device can improve the performance of establishing 5 connections.
