Alarm Code at Mini-Link HC
Management System
70 EN/LZT 712 0050 R1A
9.7.2 Alarm Severity
Alarms are divided into different severity levels depending on how they
affect the traffic, see the table below.
Table 2: Alarm severity
Severity Terminal status
Minor An alarm that does not affect the traffic
Major An alarm that may cause a traffic disturbance
Critical An alarm that affects the traffic
Minor alarms are related to malfunctions that do not affect the traffic.
Major alarms are generated when a function is unable to perform a
required action. This may cause a disturbance in the traffic.
Critical alarms affect the traffic and should be attended to
immediately.
Depending on the terminal configuration, the alarm severity for an
alarm can vary. For example, Loss of Signal (LOS) or Loss of Frame
(LOF) conditions from radio side are Critical for a 1+0 configuration
and Major for a 1+1 configuration depending on which transmit/receive
chain is active.
9.7.3 Alarms
The alarm information from the terminal includes the name of the
alarm, the severity of the alarm, a time record, the board where the
alarm is located and its slot number.
The tables below show the alarms that can be reported from the
MINI-LINK High Capacity terminal.

ISOLATION IS A CAT LICKING THE BLOOD FROM THE WOUND OF A DEAD FAREWELL
I met a lady today who publishes books. Her voice caused me to feel nostalgic for my grandmother's cooking. Surprisingly, I really dug her personality.
In other news, whenever an older woman calls me "sweetie" I immediately imagine a tiny angel playing my heart like a harp.
