It proceeds via the outgoing call line of each block 1, and individual calls from other blocks 1. are sent to this unit via the incoming call line. Since not only the connection between blocks 1 through block 2 can be made, but also the connection of this link to the four-wire executive lines of the selective connection of one of the blocks 1 participating in this connection, to reconcile the two-wire line between blocks 1 with four-wire selective channels, transmission control from the subscriber is applied, i.e. organized simplex negotiation regime. In this case, block 2 is connected to each block 1 by forward and reverse control lines.

Each block 1 is connected to a four-wire executive electoral lines with intermediate points - executive units 4, lines of direct operational communication with telephones 3, PBX lines and four-wire control telecommunication lines, at the same time, this block 1 acts as an intermediate point on this line of electoral control.

Block 1 works as follows.

When connecting the dispatcher's connection, for example, to the local subscriber, the dispatcher presses the corresponding button in block B, the output of block 9 is the code signal corresponding to the button pressed. This signal is fed to the input of block 10, where it is fixed, the definition of the connected connection, and then on the information outputs of block 10 there appears information that both connections need to be connected, and then a control signal appears on the second control output block 10, connecting exactly this connection of this type, Toe. connection of the required local operational subscriber.

Similar actions are carried out when the required block 1 is connected. Only in this case, instead of the control signal at the second control terminal 3. one

During block 10, a control signal appears at the fifth control output of block 10, and control signals are similarly supplied for the operation of the encoder 11, i.e. The signals at the information outputs of block 10 first appear and only after that the control signal appears on it. the first control output, the triggering code sensor 11, which forms the code of the voice selective call along the line to the executive lines of the selective communication in block 12.

To connect the dispatch electoral communication line to the dispatcher, press the corresponding connection button in block 9 and the control signal to connect the control link to block 13 appears at the fourth control output of block 10.

The dispatcher carries out all the service calls by means of block 13, the loudspeaker communication devices (microphone and loudspeaker) are always connected

by means of a signal line to the executive electoral lines through block 12, i.e. the dispatcher is always on the loud-speaking control of the main type of communication - executive election lines for receiving a voice call from the intermediate execution units 4. The dispatcher talks on all other types of communication are carried out using the handset of the block 13. via the signal two-wire line connecting block 1 2 with blocks 5 and 6.

The signal line of the unit 13 is connected to the unit 12 for reserving the loudspeaker devices by the microphone tube. Negotiation of the dispatcher of unit 1 over two-wire lines with the subscribers of the local operational and technological communication of the PBX via block 5 and the dispatchers of the other blocks 1 through block 6 are carried out in duplex using a handset.

The dispatcher's talks on the four-wire top-level selective communication line through block 7 are carried out in a simplex manner using a handset with a tangent cable, switching control is performed on the transmission control output of block 13 connecting block 13 to block 7.

from signal bus to signal bus four wires.

To provide a simplex talk mode when mating a two-wire communication line between blocks 1 and four-wire executive electoral communication lines, each block 1 of block 13 is connected by a transmission control line with block 6. When negotiating this connection between blocks 1, this signal is through block 6 enters through the forward control transmission line of this block 1 to block 2 (block 15) on the reverse control transmission line of another block 1 participating in this connection, and controls through block 6 simplex re- Imom talking on the four-wire communication channel.

Block 2 works as follows.

When an outgoing call arrives, for example, from one block 1 to another block 1, the first block 16 senses the connection of block 1 to this type of communication and records its call to another block 1, whereupon control signals from block 16 are received. Preparing in block 15 a forward control signal from the second block 1 and transmitting it to the first block 1 as a reverse control signal for the first block 1, receiving a forward control signal from the first block 1 and transmitting it to another block 1 as a reverse control signal for him; at

block 14, the connection of the subscriber line of the first unit 1 to the subscriber line of another unit 1.

In this case, call control tones are sent from block 14 to the first block 1 via the subscriber line, and from the second block 16 via the incoming call line to the corresponding block 1: a call signal is received from the first block 1.

I The dispatcher of the second block 1 sees the call from the first block 1 and, by pressing the corresponding button, connects I to this connection. In this case, the PB line goes; the call from the second block 1 is called and the second block 16 perceives the connection of its block 1: to this type of communication and records its call to the first block 1. At the same time, control is received from the second block 16 - The existing signals to the corresponding blocks of block 2 are similar to connecting the first block 1. The control output signals of the first and second blocks 16 coincide. In block 14, the signal line of the first block 1 is connected to the signal line of the second block 1, the call control signal is disconnected fromsignal whether

Research institutes of the first block 1, forward and reverse control signals are transferred between these blocks.

Block 10 works as follows.

When a control signal is received from the button code from block 8, pressed by the controller, the element OR 18 is triggered and the output signal appears to allow the generator 19 to work, and the prohibition is also removed from the reset input of block 17. The driver 19 operates. The first output is a pulse recording signal, which acts on the recording input of block 17, the input information from the information inputs is pending on block 17, and the code information about the pressed button appears on its outputs. The upper three bits of the V9G Kodo message are address, i.e. the type of connected communication is determined, and when information arrives on these bits, multiplexer 20 switches its input to a certain output corresponding to the inclusion of the required type of communication.

shaper 19 receives a signal connecting the desired type of communication that passes through the open channel of multiplexer 20 to the corresponding output of block 10.

Block 6 works as follows.

When a control signal arrives at the input of block 21, the signals of the information inputs are fixed in it, i.e. The j-ta output of block 21 appears. These signals arrive at the input of block 23J where it is fixed, and at the same time, at its control output for the entire time of the closure of this type of communication, there appears a signal preparing the operation of the AND 24 and trigger 25. In switch 26, under the action of this signal, the signal line of block 6 is connected to a two-wire signal line.

At the output of block 23, a connection signal appears (analogous to picking up a tube in a telephone set), and then a pulse signal appears to call the required block 1 (similar to dialing a number on a telephone set).

The signal from block 21 is fed to receiver 22 and an output link indication appears at its output. When an incoming call on any of the lines of the incoming call to block 6 appears on the corresponding output of receiver 22. Call indication from the called b / 1ka 1. If the called block 1 is the one that was called at the moment, the connection indication does not change. If after this, respectively, the called block 1 is turned off, i.e., the call signal disappears on the corresponding line of the incoming call, then a pulse reset signal appears on the control output of the receiver 22 and acts on the block 21, returning it is in its original state.

If, when the connection is established, block 6 receives a connection signal to the execution channels, then the trigger 25 switches and its control signal appears at its output to the control input of the switch 26, and the two-wire signal line switches to the RX signal line and on arrival To the input of block 6 of the reverse control transmission signal, a signal line is connected to the signaling line of the TX.

Block 7 works in a cneAyjoiHiiM manner.

When a recording control signal arrives at the input of block 27, it records the signal of connection to this type of communication. In this case, the receiver 31 fixes the connection and turns on the signal to indicate the connection is connected, the operation of the element 28 is prepared, the trigger 29 and the signal two-wire line is switched to receive from the communication channel. When a transmission control signal arrives, the two-wire signal line is switched through the switch 30 to a channel,

If the signal of connection to the executive selective communication channels is received, then the trigger 29 and the switch 30 receive a signal, the switching signal) of the first output of unit 7 at its output.

Receiving a voice-frequency selective call from a four-wire command selective link is performed by the receiver 31, and the call indication signal is degraded at the output.
