RDN-CABLE-SPECTRUM-GROUP-MIB Table View

This table keeps the records of spectrum groups. These groups
can be configured and activated by the spectrum manager and used
by the CMTS upstream port for frequency hopping. 
          
In this table, certain objects will apply DRX and CMTS 2x8 cards,
and others will apply to CMTS 1x8 and 1x4 cards, as indicated in
the individual DESCRIPTION statements.
          
For DRX and CMTS 2x8 cards, all member channels of the same spectrum group 
must reside on the same, physical 2x8 card in the chassis.
          
As the normal practice, it is recommended that all receivers on the 
same CMTS card should be physically cabled together.  At a minimum, 
all receivers in spectrum group should be cabled together.
          
If receivers are in different spectrum groups, it is expected that
they can independently reuse the same spectrum, so must *not* be 
physically cabled together.
          
For CMTS 1x8 and 1x4 cards, it is not forbidden to add receivers
from different cards to the same spectrum group, but this is not
recommended.

This table keeps the records of spectrum band scheduled for
a specific spectrum group. 
          
This table applies to CMTS 1x8 and 1x4, only.

This table keeps the records of spectrum hopping rules for
a specific spectrum group. 
          
Certain objects in this table apply to all CMTS card types,
while others might apply to DRX and CMTS 2x8, or only to
CMTS 1x8 and 1x4, as indicated by the individual 
DESCRIPTION statements.

This table keeps the records of the associations between 
upstream ports and spectrum groups.
          
For CMTS 2x8 cards, all members of the same spectrum group 
must reside on the same physical card.
          
Channels on CMTS 1x8 and 1x4 cards can be mixed in the same
spectrum group, but they may NOT be mixed in the same spectrum
group with CMTS 2x8 channels.
          
As the normal practice, it is recommended that all receivers on the 
same CMTS card should be physically cabled together.  At a minimum, 
all receivers in spectrum group should be cabled together.
          
If channels are in different spectrum groups, it is expected that
they can independently reuse the same spectrum, so must *not* be 
physically cabled together.
          
For CMTS 1x8 and 1x4 cards, it is not forbidden to add receivers
from different cards to the same spectrum group, but this is not
recommended.

This table stores the noise and error rate for the different 
frequency bands.  This table applies to all CMTS card types.

This table stores the spectrum quality information.
          
This table applies to all CMTS card types.

This table keeps the records of spectrum usage.
          
This table applies to all CMTS card types.

This table provides the statistical data collected
as a result of a FFT measurement, initiated by
setting rdnCableFftConfigSpinLock.
          
This table applies to CMTS 2x8 cards, and to BSR2000.

This table allows configuration for SNR tests. These tests
are performed on the ninth receiver for diagnostic
purposes.
          
This table applies to CMTS 2x8 cards, and to BSR2000.

This table allows activation of SNR test. These tests are
performed on the ninth receiver of 2x8 CMTS for diagnostic
purposes.
          
This table applies to CMTS 2x8 cards, and to BSR2000.

This table provides the SNR data directly from the CMTS
card. CMTS card only keeps the latest results from an SNR
measurement.
          
This table applies to CMTS 2x8 cards, and to BSR2000.

This table provides the list of cable modem mac addresses
that were selected / specified for the SNR test.

This table allows configuration of automatically
repeated SNR tests, using a specified loop count
and a specified center frequency. 
These tests are performed on the ninth receiver for 
diagnostic purposes.
          
This table applies to CMTS 2x8 cards, and to BSR2000.

This table provides the SNR loop test results,
for a test previously initiated through the 
rdnCableSnrLoopTestTable.   Results are reported 
directly from the CMTS card(s).
          
This table applies to CMTS 2x8 cards, and to BSR2000.

This table allows configuration of the modulation profile 
for SNR and LOOP tests.
          
This table applies to CMTS 2x8 cards, and to BSR2000.

This table is an expansion table for the rdnSpectrumGroupTable,
and defines the SNR thresholds for each possible modulation type.
          
This table applies to CMTS 2x8 cards.
