ABSTRACT:
The invention provides a circuit for monitoring predetermined performance criteria of a transmission link by measuring a predetermined ratio of events in a data stream. A first counter having a predetermined maximum count is responsive to each of periodic predetermined occurrences in the data stream and a clock pulse for also increasing its count by one. A second counter having a predetermined maximum count is responsive to each error of predetermined type in the data stream and a clock pulse for increasing its count by one. The overflow output of the first counter is connected to the clear input of the second counter and the overflow output of the second counter is connected to the clear input of the first counter. A signal appearing at the overflow output of the second counter indicates that the predetermined ratio of events in the data stream has not been met. The circuit also provides turn-on, turn-off hysteresis.
