Are you talking about Downstream as in an HFC plant? If so, then read on.. if not, click the X in the upper right hand corner! :)
Correct me if I'm wrong here, but I haven't ever seen any HFC stuff on the CA website. So if you mean QAM frequencies (downstream/Forward Path), as far as I know spectrum doesn't have an RF monitoring section so each 6Mhz (or 8Mhz) wide freq cannot NOT be monitored. But, the freq carrying device can be monitored if it has a management port with a routable IP Address configured. If you mean Downstream as in CMTS, yes and no. You can monitor each downstream interface by simply assigning an IP Address and monitor that (or use SNMP to monitor the entire box). This will also be the same for DTI Servers, optical receivers, and any passive cabling network, even if it has a monitor port on the spliter/combiner. As far as I know, you cannot monitor the frequency (snr, cnr, power, etc.) itself as if Spectrum was an RF Analyzer.

I think I know the answer but want to through it out there anyway. Will turning off polling to an upstream device affect Spectrum's ability to isolate faults for the downstream devices? I believe it will not, but wanted to double check.
