Cisco CMTS SNMP OID's

[Lorell Hathcock <lorell () hathcock org>]

All:

Does anyone out there have some valuable OID's for a Cisco CMTS?

The ones I am looking for are:
        Signal to Noise per upstream channel
        Cable Modem counts of all kinds
                connected / online
                ranging
                offline 

I opened a ticket through Cisco's help desk.  I have a SmartNET contract for the unit, but they were not very helpful.  
The OIDs they suggested did not yield any useful data.  ("0" when I know there are CMs connected, etc).

Thanks in advance.
