Description

M

The invention relates to communication technology and can be used in automatic telephone stations (AMTS) for measuring the statistical parameters of a telephone message.

The purpose of the invention is to improve the accuracy of accounting for the distribution of calls and failures along parts of the switching path.

Figure 1 shows the structural electrical circuitry of an automatic metering device for the distribution of calls and failures on a telephone network; Fig. 2 shows a structural electrical circuit of the connection unit; FIG. 3 shows a structural electrical circuit of the dial lock.

The device for automatic recording of call distribution and refusals to the telephone network includes a connection unit 1, an encoder 2 directions, a relay 3 times, an encoder 4 codes, an encoder 5 channels, a set latch 6, a block 7 coupler with a perforator, a perforator 8 and 9 time marker. The connection unit 1 contains (FIG. 2) connecting elements 10, connection permission cells 11 containing a delay element 12, a trigger 13 and a diode 14, a single vibrator 15 and inverters 16. A dial fixator 6 contains (FIG. 3) the element OR 17, the first one vibrator 18, a counter 19, a second one-shot 20, a transistor switch 21, and a diode array 22,

The device works as follows.

When connected to the telephone station, the connection unit 1 is connected by a group of wires to the outgoing tone dialing kits (ICTN) of the outgoing telephone stations, which are channel devices. When establishing the ICTN AMTS connection and the incoming tone dialing set (VKTN) at the incoming station exchange the interaction signals: Send the code (PC), local code, Send the number (MON), the called party number, the Call Control Signal (CPV), which is a sign of subscriber free, signals are Zanto (C3) 5 and Decade of Occupation (DZ), in the latter case in the absence of free channels in the transit point.

the presence of a short-term negative or zero potential at the respective stages of connection establishment, are routed to the connecting elements 10 of the connection block 1, the corresponding outputs of the connecting elements 10 of the block 1, the connections (i.e., performing the same function) are connected in parallel except the outputs defining directional code and channel number. Thus, the connecting elements of the connection block 1 are individual for each ICTN, and the remaining elements of the connection block 1 and all the other device blocks are grouped, which allows the device to serve all ICTN alternately as the incoming ICTN, t. e. perform automatic sampling from the call flow of subscribers.

In the initial state, from the trigger 13, the cells 11, to the elements AND to all the connecting elements 10 of the connection block I, a resolving negative potential comes in. When an ICTN is occupied, the latter sends a busy signal to its associated VKTN at its incoming end VKTN queue sends a PC signal to ICTN. When IKTN receives this signal in the corresponding connecting element 1 O of the connecting unit 1 on one of the wires of the first input (first from the bottom in FIG. 2) a negative potential appears briefly. Thus, at the second input of the unit 1 and the connecting element 10, the second permissive potential appears, the transistor switch connected to its output with the load in the form of a relay operates.

After the relay has triggered, all wires connecting this connecting element 10 to the corresponding ICTN are connected. Through the output of the connection block 1, the PC signal, which is in this case the direction cipher in which this ICTN operates, is fed to the input of the direction encoder 2 and, accordingly, to the input of one of the AND schemes of this block. To the other input of the circuit AND, through the other input of the encoder 2 of the direction, from the output of the connection block 1, the second resolving potential is fed from the same trigger 13 of the cell 11, from which it enters the circuit AND of the connecting elements 10. Poe10

5 1570023 to this scheme AND direction encoder 2 is triggered, from its output through the output of the encoder 2, the potential enters the encoder 4 of the code, from which it is encoded into the corresponding symbol of the telegraph code and output of the latter through the output of the encoder 4 of the code at the entrance of the perforator 8 for imprinting on a punched tape.

At the same time, the potential from the output of this circuit AND the encoder 2 of the direction in the same block enters the input of the OR circuit, and from its output through the output of the block to the input of the relay 3 times. From the leading edge of the pulse, the single-oscillator of the relay 3 times is triggered and at its output for 40 s in general there appears a negative potential that enters the input of the connection unit 1. In block I, it connects through trigger element 12 to trigger 13 and directly to contact to close relay of connecting elements 10. Because at a given time in operation one connecting element 10, the relay of this connecting element through its own from ICTN to input connection (second wire from the bottom) enters. inter-country code. In the case of a transit connection, it consists of three digits, and in the case of a terminal connection it consists of a single pulse of 50 ms duration - units (I). The long-distance code through the inverter 16 and the output of the connection unit I is fed to the input of the latch 6 of the set in which the boot is fixed, and then, after being converted to the encoder 4, is printed. The signal PN comes from ICTN to the input of block 1

The contact is self-blocking. The delay of 30 hours of a pulse (the triggering of the next time is equal to the duration of the signal of a consecutive counting cell) of the PC (250-300 ms) and necessary for spreading on the falling front (decay) of the engine of the perforator 8, since it can in a disabled state. After the time delay of 250-300 ms has expired, the trigger 13 of the 1b cell is triggered and a zero potential appears at its output, as a result of which the triggering permission from all the elements AND of the connecting elements 10 is removed -4o (one transistor switch 21 is open and for them it remains in operation due to self-blocking of the relay), simultaneously through the output of block 1 connecting zero

pulse. Elements 20 and 21 and the diode array 22 serve to determine the beginning of the inter-series time. This happens as follows. In the presence of a pulse at the input of the retainer 6 of the set, it goes simultaneously to the elements 20 and 21, while

the potential is fed to the input of the direction encoder 2 and stops the flow of the direction code to the encoder 4)

The zero potential from the output of block 1 of the connection is also fed to the input of the 5 channel encoder. The channel number from the output of block 1 through the input of the channel's encoder 5 passes to its output, enters the input of the encoder 4 codes, converts here to a combination of potential signals corresponding to the channel number, and then goes to print. The duration of the combination is 50 ms.

Due to the presence at its output of zero potential, the diodes of the matrix 22 will block all outputs of the counter 19, therefore, at this time, the accumulated information in it (the number of recorded current digit pulses) from the output of the dial 6 is not received. Front edge

Next, the ICTN receives the connection code (second wire from the bottom). In the case of a transit connection, it consists of three digits, and in the case of a terminal connection it consists of a single pulse of 50 ms duration - units (I). The long-distance code through the inverter 16 and the output of the connection unit I is fed to the input of the latch 6 of the set in which the boot is fixed, and then, after being converted to the encoder 4, is printed.

the pulse of the pulse (the operation of the next sequential counting cell) occurs on the falling edge (decay) of the entire existence of the pulse, the transistor switch 21 is open and

Due to the presence of zero potential at its output, the diodes of the matrix 22 will block all outputs of the counter 19, therefore, at this time, the accumulated information in it (the number of recorded current pulses of the digit) from the output of the dial 6 is not received. Front edge

the pulse through the auxiliary input (with a capacitor) must reset the one-shot 20 to its initial state (when its output has zero potential), in a particular case during

first pulse one-shot 20 yet. is in its original state.

During a rauey between pulses of a series, transistor switch 22 must

it would close, but the one-shot 20 starts up from the trailing edge of the dialing pulse and keeps the transistor switch 21 in the open state, which means the prohibition of the transfer of the recorded data in the counter 19 co. stored. The delay time of the one-shot 20 is 1.5 periods of the total pulse-pause time, i.e. 75-80 ms. With the beginning of the next pulse, its leading edge through the additional scatter (with a capacitor) of the one-shot 20, it is reset, thus, during the accumulation of digit pulses until the end of the pulse train, the transfer to the encoder of the result code is prohibited during the pulse a transistor switch 21 directly by the pulse itself, and during a pause, the transistor switch 22 is held in the open state by a single-hole rep. 20.

After the end of the last pulse of the series, as usual, the single-oscillator 20 starts, but the first pulse of the new series comes after a time several times longer than the one-shot shutter speed 20, so after the end of the shutter speed the one-shot 20 comes back to its original state, too - closes. Now the diode matrix 22 is no longer working, and the negative potential from the corresponding open cell of the counter 19, the number of which determines the fixed digit, enters through the output of the dial lock 6 of the dial to the input of the encoder 4 of the code, where it is converted into a telegraph code and further the output of the encoder code is printed. At the same time, from this output of counter 19, the potential arrives at the input of the element OR 17, from the output of which the one-shot 18 starts, determining the duration of a print pulse (50 ms), t, e0 the total information stored by the counter — the figure “After the end of the one-shot 18” by dropping (falling edge) of its pulse, counter 19 is reset, and it comes to its initial state, and its zero cell (determining the initial state) connected to the input of transistor switch 22 opens it, and the outputs of counter 19 are locked.

Now, ICTN connection establishment technology can do

signal KPV, which indicates that the called party is free, or Sz. The first signal is fed to the input of the connection block 1 (via the fourth wire from the bottom), then through the output of the connection block it goes to the input of the encoder 4 codes and then after conversion to the telegraph code through the output of the encoder 4 codes to print. At the same time, this signal is fed to the input of the relay 3 times. At the time 3 input of the relay, the CPV signal rises through the charging time, the driver circuit, which is necessary for the normal signal from the perforator 8, the relay time 3 is reset. After charging this circuit (50 ms). Sz operates in the same way, it only arrives at the input of the connection unit 1 along the bottom of the wire, from the connection unit 1 through its output it enters the input of the encoder 4 codes and the input of the relay 3 times. A DZ signal with the same result comes through the same circuit. In particular cases, CPV and SZ may occur in the early stages of a joint. All these three signals (QCS, C3 and DZ) are final and bring the device to its initial state, since after releasing the relay 3 times at its output and, accordingly, at the input of the connection unit 1, the negative potential changes to zero, the relay in the connecting element 10 no longer receives the voltage to block, simultaneously from. the zero potential at the input of the connection unit 1 in its cell 11 is reset to the initial state by the trigger 13, and the device is ready to work with the new call,

If after 40 from signals DZ, KPV or SZ does not come (including the failure of any of the considered signals), one-shot. the relay 3 times releases and the device comes back to its original state, but the time relay is no longer blocked and for 50 ms the output of the relay 3 times to the input of the encoder 4 codes and then a signal is received through the output to the printer indicating that the connection is not completed due to the presence of technical damage (hang) in the switching path. In all other cases, the device is released earlier, on average, in 15-20 seconds.

If the caller has stopped trying to establish a connection at any stage, then ICTN will exit

cash Disconnect. In this case, the sixth bottom wire to the input of the block 1 of the connection receives a zero potential. Having passed through the relay contacts and the inverter 16, it goes through the output of the connection unit to the input of the encoder 4 codes, after which it passes in normal order (like KPV or SZ) after encryption to print. At the same time, it is fed to the input of the time relay 3, where the same operations are performed as with the TKV and SZ signals.
