При накоплении числа ошибок, превышающего заданное за определенный про- л межуток времени (что соответствует заданному коэффициенту ошибок) с выхода измерителя 7, на один из входов блока 8 поступает сигнал.For each violation of the coding law, an impulse of 3 h - _ appears at the output of the detector 6. error signal. When the accumulated number of errors exceeds a specified time interval (which corresponds to a given error rate) from the output of meter 7, a signal is sent to one of the inputs of block 8.

Аналогичный сигнал поступает на другой вход блока 8 с выхода анализатора 5 при поступлении информационного сигнала. При поступлении одного из указанных сигналов на. вход блока 8 на его выходе формируется сигнал запуска генератора 4 и сигнал управления коммутатора 9, который при этом пропускает сигнал квитанции в линию, запрещая прохождение информационного сигнала.A similar signal is fed to another input of block 8 from the output of the analyzer 5 when an information signal arrives. When one of the specified signals arrives at. the input of block 8 at its output forms the start signal of the generator 4 and the control signal of the switch 9, which at the same time passes the receipt signal into the line, blocking the passage of the information signal.
