Smart Amplifier Ingress Noise Localization – An Integrated Solution Leveraging PNM
- Examining SCTE 279 as a standard for a new Smart Amplifier and SCTE 283 as an associated information model providing a number of monitoring and control functions
- Leveraging the integration of PNM Upstream Triggered Spectrum Capture, HFC plant topology data, and existing standalone wink switches managed by an SCTE 283 compliant interface to localize ingress noise events
- Examining and meeting the challengeof implementing these solution when considering intermittent and short-lived noise bursts, HFC plant topology discovery, and the impact on cable modems related to available transmit headroom
