Description
cascading interface.
You can configure it to
be the other outputs to
implement integrated
display of alarms. The
alarm outputs are
controlled by the
internal relay contact.
When the relay contact
is closed, the resistance
of each ALMO
interface is less than 1
ohm. When the relay
contact is open, the
resistance of each
ALMO interface is an
infinite number.
The ALMO1 and

ALMO2 interfaces have
the same pin usage and
are a pair of
housekeeping alarm
output/cascading
interfaces. Similarly, the
ALMO3 and ALMO4
interfaces also have the
same pin usage and are
another pair of
housekeeping
output/cascading
interfaces. For example,
when ALMO1 and
ALMO3 are used to
output housekeeping
alarm signals, ALMO2
and ALMO4 can be
cascaded to ALMO2
and ALM04 on another
subrack.
The OptiX OSN 8800

provides for eight alarm
outputs. By default, the
first three alarm outputs
are defined as critical
alarm, major alarm, and
minor alarm. The other
five are reserved. Alarm
