Object

column r/w hertzInteger32 
The center of the downstream frequency associated with
this channel.  This object will return the current tuner
              
frequency.  If a CMTS provides IF output, this object
will return 0, unless this CMTS is in control of the
final downstream frequency.  See the associated
compliance object for a description of valid frequencies
that may be written to this object.

docsIfBasicCompliance readonly
Read-write in cable modem termination systems;
read-only in cable modems. The values above are
appropriate for a cable plant using a Sub-Split channel
plan. If DOCSIS is extended to cover other types of
channel plans (and frequency allocations), this object
will be modified accordingly.
docsIfBasicComplianceV2 readonly
Read-write in cable modem termination systems;
read-only in cable modems.
A range of 54MHz to 860MHz is appropriate for a cable
plant using a North American Sub-Split channel plan.
The spectrum range has been expanded to accommodate
a lower edge of 47MHz and an upper edge of 862MHz
for some European channel plans.
If DOCSIS is extended to cover other types of channel
plans (and frequency allocations), this object will be
modified accordingly.
