Data
becomes
invalidated
following
a
reset.
In
the
example
below,
the
Slave
ODU
was
reset
shortly
after
08:45.
All
data
prior
to
that
time
becomes
invalidated.
The
only
valid
items
are
the
recordings
following
the
re
‐
sync.

on
the
Thresholds
RSL
Thresholds
Two
RSL
Thresholds
can
be
defined.
They
are
used
as
an
indicator
of
problems
in
the
radio
channel.
You
can
check
the
RSS
from
the
Link
Budget
Calculator
results
during
installation.
Values
of
‐
5dB
and
‐
8dB
from
the
current
RSS
are
typical.
TSL
Threshold
A
counter
is
maintained,
of
the
number
of
second
intervals
during
which
Tx
power
exceeds
this
threshold.
BBER
Threshold
The
Background
Block
Error
Ratio
is
measured
as
a
percentage.
The
threshold
can
be
set
from
0.1%
up
to
50%.
An
8%
threshold
is
recommended.
If
there
are
no
problems
during
the
interval,
then
for
that
threshold,
the
recommended
BBER
value
should
be
0.
Since
the
system
provides
a
lossless
Ethernet
service,
there
is
throughput
degradation
in
case
of
interference.
The
degradation
is
proportional
to
the
BBER.
Ethernet
Thresholds
‐
Capacity
This
is
used
as
a
basis
for
checking
adherence
to
a
Service
Level
Agreement.
It
is
the
number
of
seconds
count
that
the
link
capacity
falls
bellow
the
threshold.
Ethernet
Thresholds
‐
Traffic
The
number
of
seconds
count
that
received
traffic
exceeded
this
threshold.
It
can
be
used
to
measure
traffic
peaks.
