Satellite Interface ACM Statistics Parameters
Description
CNI CNI
Internal Es/No value used by the
ACM client on the terminal to
determine what modulation and
coding scheme will be used.
Corrected CNI Actual Es/No value used by the ACM
client on the terminal to determine
what modulation and coding scheme
will be used. Corrections are based
upon
Fwd Signal Signal Present Is the signal present (TRUE/FALSE)?
Demodulator Lock Is the demodulator locked
(TRUE/FALSE)?
Decoder Lock Is the decoder locked
(TRUE/FALSE)?
Transport Stream Lock Is the transport stream locked
(TRUE/FALSE)?
Totals Physical
Total number of physical frames
Dummy
Total number of dummy frames
Baseband
Total number of baseband frames
Feedback Interval
This is the time interval (in
milliseconds) the ACM parameters
are updated in the Terminal.
Interval Lower
Protection Level
This is duration (in milliseconds) that
the signal level has to exceed the
minimum threshold of a higher
MODCOD before requesting the hub
to switch to the higher MODCOD.
Adaptive
Average Es/No Running average of the forward
Es/No.
Average Variation Running Average of the standard
deviation of the terminal's forward
Es/No.
Es/No Average Factor Used to tweak the ACM behavior.
Value bigger than or equal to 0 and
smaller then 1.If this factor = 0, then
no averaging is applied.
Es/No Variation Average
Factor
Used to tweak the ACM behavior.
Value bigger than or equal to 0 and
smaller then 1.If this factor = 0, then
no averaging is applied.
Es/No Variation Correction
Factor
Used to tweak the ACM behavior.
Value between 0 and 10. If set to
zero, then no adaptive margin will be
used.
