The Link Alarms indicate ongoing problems.
ALOS/LOS (Loss of Signal) – This alarm indicates a complete absence of
synchronization pulses on the line.
RED (Red Alarm) - This is a local equipment alarm. It indicates that the incoming
signal has been corrupted for a number of seconds. This equipment will then begin
sending a yellow alarm as its outbound signal.
AIS (Alarm Indication Signal, or BLUE alarm) - This alarm indicates the total
absence of incoming signal as a series of continuous transitions (an all 1's pattern) is
received.
YEL (Yellow Alarm) – This alarm is transmitted to the network and alerts it that a
failure has been detected.
OOF (Out of Frame) – This alarm signifies the occurrence of a particular density of
framing error events. This alarm could signify that the wrong framing mode is
configured.
