MSOs can use new spectrum analysis application with millions of
installed cable set-top boxes, cable modems and other customer premises
equipment to significantly reduce the need for expensive field test
equipment and truck rolls
The new diagnostics application from ZCorum, called RF Inspector, gathers and presents data from Hitron cable modems that use the Intel® Puma™ 5 DOCSIS 3.0 processor and the MaxLinear MxL261 eight-channel DOCSIS 3.0 front-end receiver. The companies will be demonstrating the new product at the Hitron and ZCorum booths at the SCTE Cable-Tec Expo in
Issues perceived to be in the customer premises equipment can be confirmed or shown to be a symptom of a network problem (e.g., tap, amp, etc.) by having a view of the full spectrum at neighboring CPEs. Issues like excessive tilt, spectrum suck outs, overdriven channels, RF notches, standing waves, resonant peaking, ingress and interference can be seen easily with this system.
By leveraging the companies’ expertise in customer premises equipment and diagnostics and the tens of millions of
ZCorum already develops software-based diagnostics solutions for broadband providers, including its popular TruVizion software for cable modem and CMTS monitoring, plus an accompanying mobile app called TechVizion. ZCorum will make RF Inspector available as an optional module within TruVizion, and will also enable integration with other diagnostics platforms.
MaxLinear’s cable receivers with dual-wideband or Full-Spectrum Capture™ tuners provide embedded remote spectrum monitoring and deliver performance monitoring and remote diagnostic data for this new application. Intel provides the DOCSIS 3.0 Puma 5 and Puma 6 modem processors that support the DOCSIS 3.0 MIB for transferring the data to the CMTS. Hitron provides the high performance DOCSIS 3.0 modems, EMTAs and gateways to the cable MSOs with this feature.
