SU365851A1 - DEVICE FOR TRANSFER OF INFORMATION FROM MARKER TO REGISTER IN AUTOMATIC TELEPHONE - Google Patents

Description

The invention relates to the field of wired communication H can be found not in automatic telephone exchanges in which the token and the register exchange request and answer signals separated by pauses.

It is known a device for transmitting information from a marker to a register in an automatic telephone exchange (ATC), containing, in particular, a frequency transmitter on the H1ya connected to it, give the next digit a signal. Such a device, in the case of an uninterrupted exchange of information under a virtual code, does not automatically restore the exchange without a connection connection.

In the oppressed device, this disadvantage is eliminated by switching on the signal “not intermittently the next digit of the source of the combinations of signal“ intermittently to the next number of the signal;

FIG. 1 shows a block diagram of a device for mounting; in fig. 2 is a block diagram of the dark part used with the described device.

The device contains the source / signal "unhide the next digit connected to the converter 2, the control source 3 signal" transmit 1 and the source 4

The signal “2 and alternate 2. The converter 2 n source 3 n 4 forms the source 5 of the signal“ give the next digit.

The device has a frequency of 1 receiver (not shown in figkhrah), from which the signal is fed to block 6 of the receiver unit, barely decrypted - ator 7, latch 8. device 9 sraviein, decoder 10, latch //, source G2 sigial “Repeat the previous digit and the decoder 13 of the signal“ the release of the marker.

The device works as follows.

From the marker (in the figures it is not indicated) to the source / signal of "transferring" to the next one. The control unit is fed to the control unit. From the output of the digital source, transmit the next digit of the signal and enter the input of the transducer 2, turn on the source of the signals of transcend 1 n and transmit 2, which are switched on alternately. In this case, the marker's use of the marker is the first to turn on the source of the signal "transmit 1. then use the screen" randomly 2, and so on. The number of such inclusions depends on the number of digits that the marker of this string is scanned by the register.

If piercing and signaling of the signal exchange is performed, a previously transmitted signal is sent from the marker side in a known manner.

The operation of the device on the side of the register of the receiving part (Fig. 2) is based on the fact that in order to restore the normal exchange of signals to the averaging, the required signal of the viir is compared with the preceding signal. If these signals are different, then an answer signal is sent to the influence, corresponding to the next digit of the iomer of the called abiieiiTa, if these sigals are the same, then a response signal is sent to the line corresponding to the HUUI of the previous digit.

When a two-frequency signal arrives at the frequency-output terminal (fnigur no knockout), it is a ground note, resulting in two receiving relays in block 6 of the alternate relays corresponding to the current signal. When the signal is transmitted, pass 1 and the output of the decoder 7 and is the signal leading to the triggering of the latch 8, which affects the comparison device 9, is n1, it is i) the initial state, since this signal differs from the previous one; sigpala) At the output of the comparison device, the message appears. “Pass the next digit, which through the connection stage goes to the register (in the figures and shows).

If after that the sigpal pass 2 is received, then in the receiving relays block, the relays corresponding to this signal, the decoder 10, the latch 11, and the comparison device receive the corresponding terminal, and the latch 8 is turned off.

The change of signals in the comparison device is registered as a fact of differences in the signals, and the output of the comparison device is the message "iredite the next digit. EU; 1And the signal change is not happening, which can occur if the response signal was not recorded on the side of the marker, then the output of the device compares

change signals. As a result, the source 12 of the signal “and the previous digit” is triggered and the corresponding signal is transmitted to the line. Before releasing the marker to the side

the register is sent a release marker to the marker, which is allocated by the decoder 13, a latch // and a comparator are fed. Sigal from the output of the descrambler sshnala "the release of the marker blocks

the device is compared, due to which it is not possible to transfer to the side of the marker and ()) the name of the caller's iomer.
