Note
the
following:
•
Compression

the
Tx
compression
path
(LAN
to
Satellite).
When
Enabled
,
ALL
traffic
on
all
active
ports
and
all
active
PIIC
interfaces
will
be
routed
through
the
compression
card
and
will
be
compressed.
Tx
Compression
(LAN
to
Satellite)
requires
activation
of
a
software
license
or
FAST
Access
Code.
Tx
compression
rate
licenses
are
sold
by
the
symbol
rate,
so
maximum
data
rates
will
depend
on
modulation
and
coding
schemes
used.
When
Compression
is
Enabled
,
the
Tx
side
of
the
modem
will
be
symbol
rate
‐
limited
by
the
lesser
of
the
Tx
symbol
rate
purchased
or
the
Tx
compression
symbol
rate
purchased.
All
other
licenses
(e.g.,
CnC
data
rate)
will
still
apply.
•
Decompression
enables
or
disables
the
Rx
decompression
path
(Satellite
to
LAN).
The
decompression
setting
must
match
the

A
mismatch
will
cause
all
data
to
be
dropped.
Rx
decompression
does
not
require
a
software
license
or
FAST
Access
Code;
Rx
decompression
will
work
at
all
data
rates
regardless
of
the
Tx
compression
license
purchased.
