ANSI SCTE 235:2017 pdf free download – Operational Practice for the Coexistence of DOCSIS 3.1 Signals and MoCA Signals in the Home Environment
This document provides many recommendations for operational best practices for the coexistence between DOCSIS 3.1 signals and MoCA signals. Each recommendation is preceded with the text “Guideline” and is numbered. The guidelines are summarized in Section 12. This document demonstrates that the hybrid fiber coax (HFC) network performance impacts the calculations. The initial conclusions are conservative in light of the ability of DOCSIS 3.1 technology to adapt to real-world environments. Final calculations are based on the selection of optimal DOCSIS 3.1 bit loading, which allows adequate performance with less isolation.
1.2. Scope
This operational practice applies to any network that contains DOCSIS downstream signals at frequencies greater than 1 GHz and has MoCA signals in the premises. The calculations are valid for DOCSIS 3.1 and for MoCA 1.1 and 2.0 single channel operation.
1.3. Benefits
The recommendations in this document are designed to assure that the DOCSIS networks and MoCA networks perform with minimal impact on each other. If these recommendations are not followed, significant performance degradation could occur to either network and, in some scenarios, one or both networks could completely fail to operate.
1.4. Intended Audience
This operational practice is intended to be used by network designers, cable industry technical personnel,equipment designers and others who have an interest in coexistence of DOCSIS 3.1 signals and MoCA signals above 1 GHz to assure that proper frequencies are selected and that proper filters are specified to be installed.
