Appendix G. ETHERNET
STATISTICS and STATUS
REPORTING
G.1 Introduction
Information
is
available
from
the
CDM
‐
750
Advanced
High
‐
Speed
Trunking
Modem
to
report
ongoing
and
time
‐
varying
quantities,
along
with
some
operational
status
items.
Of
particular
interest
in
this
section
are
those
related
to
the
Ethernet
data
traffic
associated
with
normal
operation
and
metrics
–
i.e.,
items
that
are
attributed
new
meaning
in
special
modes
like
Adaptive
Coding
and
Modulation
(ACM)
or
DoubleTalk
Carrier
‐
in
‐
Carrier
(CnC).
All
of
the
metrics
(counts,
configuration,
ratios,
etc.)
are
referred
to
collectively
as
statistics
.
(For
the
purpose
of
this
application,
the
intent
of
using
the
word
‘statistics’
here
is
to
gather
naturally
associated
items.)
This
appendix
excludes
much
of
the
information
provided
elsewhere
in
this
manual
(e.g.,
Es/No,
RSL,
etc.)
in
order
to
focus
strictly
on
data
traffic
‐
related
items.
G.2 Data Flow Diagram
provides
a
simplified
way
to
visualize
the
CDM
‐
750
and
its
data
traffic
handling
capabilities.
While
this
diagram
includes
a
few
of
the
normal
modulator
and
demodulator
features,
its
primary
purpose
is
to
emphasize
the
blocks
involved
in
data
flow.
Note
the
following:
•
The
names
of
the
blocks/regions
correspond
to
generic
functions
within
the
modem.
•
The
blocks
in
this
diagram
are
numbered
to
indicate
valid
traffic
flow
between
blocks.
•
Data
flow
only
occurs
as
indicated
by
the
lines
in
the
diagram.
For
example,
data
flow
from
Blocks
1
to
2
is
valid
,
while
data
flow
between
Blocks
2
and
8
is
not
.
