[Irgiz]-1, equipment for testing the channel Of [e]1.

The special features of this equipment are:

• light-emitting diode indication;
• acoustic signaling;
• mapping the current errors;
• mapping the errors, which occurred based on the moment of initializing the indicator;
• the possibility of nourishment from the small batteries;
• compact sizes.

Indicator ensures detection and mapping:

• the absence of the digital signal Of [e]1 beyond the entrance, including of short-term, caused “variable contacts” before the cross-connecting connections (LOS);
• the presence in circuit Of [e]1 of emergency signal both specially transferred, and short-term, caused “variable contacts” before the cross-connecting connections (AIS);
• mapping the current errors;
• the presence of bit errors in the checked circuit (ES/SES);
• the disappearances of the electric power supply of indicator, possible with the conducting prolonged checkings and monitoring.

Indicator provides the possibility of full-duplex operation with testers and analyzers of the type Of [k]4305, MORION -[E]1, [TTSK]-[E]1, [E]2 and by others with checking of the circuits Of [e]1 is separate before the directions of transfer. Diagram of the start
