How it works
The G1001-CR G.hn to Ethernet Managed Demarcation Point devices power the Positron rugged IP67 (outdoor and extended temperature) GAM family with support for the ETSI Reverse Power Feed (RPF). Support for RPF facilitates the installation of the GAM outside of the MDU or MTU and in areas where it is not simple or cost effective to install a local power source. The GAM-4-CRX has four (4) COAX ports and can operate when powered from G1001-CR devices. Each G1001-MR or G1001-CR powers a single G.hn port of the outdoor GAM devices.
The ITU-T G.9960 G.hn Wave-2 standard leverages the existing telephone wiring (UTP, CAT-3 or CAT-5/5e) or RG-6/RG-59 coax cabling as an access technology that delivers a Gigabit Internet service to each subscriber at a lower cost and without the complexity and delays associated with in-building fiber installation. G.hn is used as an Access technology by Operators looking to simplify their access network and backend infrastructure with an Ethernet-like technology that is highly scalable without some of the inherent complexity of DSL-related technologies. Operators increasingly rely on G.hn to extend fiber or fixed wireless Gigabit services and avoid the high capital and operational expenses of a fiber retrofit. The Positron GAM solution is MEF CE 2.0 compliant and is ideally suited to deliver Business Ethernet services in an MDU and/or MTU deployment.
About the G1001 Managed Demarcation Point with RPF Support
When operating in a Reverse Power Feed mode, the outdoor GAM devices will always make sure that each G.hn End-Point devices it serves evenly contribute to provide power to the GAM via RPF. This means that the outdoor GAM will reject G.hn End-Point devices that do not provide their share of the power required by the GAM.
The G1001-CR device controls how a Residential Gateway (or User CPE) connects to the G.hn Access Network under the control of the Positron GAM. In this role, they make sure the information transmitted over the G.hn links is protected with strong AES-128 encryption. When used in Point-to-Multipoint mode (coaxial wiring), the G1001-CR operates under control of the GAM to isolate the traffic from each subscribers that share the same coax splitter.

Now is the time for fiber operators to address the MDU challenge
In a new Broadband Communities article, Pierre Trudeau, President of Positron Access Solutions, explores one of the biggest opportunities facing fiber operators today: bringing Gigabit broadband to residents in existing MDUs without the cost and complexity of rewiring. The Positron GAM is the purpose-built multi-subscriber MDU ONT solution that makes this approach possible, leveraging the existing coaxial or telephone wiring to extend Gigabit connectivity to every resident.
