Demystifying OOB and R-PHY

Mia Colabrese2020-04-02T12:21:56-04:00December 14th, 2018|

Benefits and Limitations, Choose your R-PHY Wisely In this article we dive into Data-Over-Cable Service Interface Specifications (DOCSIS) remote PHY (R-PHY) testing challenges and how these can be overcome using out-of-band (OOB) channel communications. Test and Measurement Challenges with R-PHY Let’s understand the fundamental challenges with testing in an R-PHY world. Today’s radio frequency (RF) test equipment, such as sweep, return path monitoring, and leakage is based on analog signals. Figure 1 illustrates how typical headend / hub test equipment signals traditionally flow to or from an analog

Proactive Network Maintenance and Signal Leakage Tools

Mia Colabrese2017-09-26T11:49:50-04:00September 26th, 2017|

A Field Study on Proactive Network Maintenance and Signal Leakage Tools The objective of the field study was to determine if a direct correlation exists specifically between Nimble This PNM drop, in home / near home data and leakage. More specifically: What percentage of the time can Nimble This PNM data be used to proactively identify drop, near home / in home impairments that will have cable integrity issues that the subscriber will notice in the immediate future and these impairments can be located / fixed using ComSonics
