Abstract

The invention relates to communication technology. The purpose of the invention is to automate equipment testing. The device contains a receiver 1 pulses, a receiver 2 frequency signals, a counter 3, an answering machine 4, a lock 5 and switches 6 and 7, as well as the test: a set of 8 relay connecting lines and a connecting line 9. In set test mode 8, the receiver 1 detects it the number that is fixed by the counter 3. Counter 3, through switch 6, performs occupation of set 8 and connection of answering device 4 and blocker 5 to it. Answering device 4 transmits a buzzer to the conversation path of set 8. At the end of the occupation of set 8, switch 6 turns off t counter 3 from receiver 1. When a defective set 8 is detected, receiver 2 activates lock 5, which disconnects set 8 from the PBX equipment. In line 9 test mode between PBX, receiver 2 connects switch 7 to counter 3. Counter 3 records line number 9 received by receiver 1 and through switch 7 disconnects line 9 from the communication channel compression equipment. The nature and location of damage to line 9 are determined at the node PBX. The goal is achieved by providing a remote connection via connecting lines. 1 sludge.

The invention relates to communication technology and can be used for remote testing of sets of relay connection lines and connection lines.

The purpose of the invention is to automate the verification by connecting remotely via connecting lines.

The drawing shows an electrical block diagram of a device for testing the equipment of automatic telephone exchanges.

The device contains a receiver 1 pulses, a receiver 2 frequency signals, a counter 3, an answering machine 4, a lock 5 and switches 6 and 7. The drawing also shows the set of relay connecting lines 8 and connecting line 9 being tested.

The device works as follows.

In the test mode of the sets of relay connecting lines 8, the receiver 1 with the appearance of a single pulse at its input prepares the counter 3 for operation. and through the switch 6 it carries out the test of the relay set of the connecting line 8 and connects to it the answering machine 4 and the blocker 5. And the answering machine 4 transmits the buzzer to the conversational path of the relay the set of the connecting line 8. Upon the completion of the occupation of the tested relay set of the connecting line 8, the switch 6 disconnects the counter 3 from the receiver 1, as a result of which the subsequent series of pulses of the dialing number

Upon detection of a faulty tested set of relay connecting line 8, a short frequency message is fed from the node PBX, which is fed to the input of receiver 2 of frequency signals, which activates blocker 5, which disconnects the tested set of relay connecting line 8 from the equipment of the automatic telephone exchange,

It is possible to unlock the tested set of relay co-op of line 8, for this purpose, a continuous pulse and frequency package is sent from the node PBX, pulse receiver 1 and receiver 2 frequency packets receive a command and turn off the lock 5, which restores the sample circuit of the relay link tested set eight.

In the mode of checking the lines between telephone stations, the receiver of 2 frequency signals receives a long bout and connects switch 7 to counter 3. Next, a series of pulses arrives at the input of the impulse receiver, determining the number of the tested connecting line 9. Counter 3 captures the received the number and via the switch 7 disconnects the tested connecting line 9 from the communication equipment of the communication channels (not shown). At the node PBX, the insulation resistance of the wires of the tested connecting line 9 is measured.

After removing the frequency 11 parcel, the receiver 2 of the frequency signals through the switch 7 performs the commutation of the wires, as a result of which the wires of the test connecting line 9 are short-circuited and grounded. On bonds

from the communication channel through the receiver 1-ds of the secondary automatic telephone exchange, measurement of the pulses and the autoresponder 4 is carried out to the relay relay connection set 8. When the pulses of the norm dialing pulses are received at the input of the receiver 1, the received information is transmitted to the relay connection set 8 which, in turn, transmits information to the communication channel of the communication channel equipment and further to the host PBX (not shown), where the operation of the tested set of relay connections is monitored by line 8.
