Description: The number of seconds in which line Alarm Indication Signal (AIS) has occurred. A line AIS is asserted when a 111 binary pattern is detected in bits 6,7,8 of the K2 byte for five consecutive frames. A line AIS is removed when any pattern other than 111 is detected in these bits for five consecutive frames.

What is sonetLineAISs?

Counts the number of seconds during which this port detected a Line Alarm Indication Signal, asserted when a 111 pattern appears in K2 bits 6-8 for five consecutive frames. An admin treats a rising count here as a sign of an upstream failure being signaled toward this port.
