Delivering Gigabit to the Home

Positron G.hn to Ethernet Managed Demarcation Point

“Fiber to the Home” is far from the only and most efficient technology to deliver Gigabit Internet access to subscribers. Retrofitting an existing (brownfield) Multi- Dwelling Unit (MDU) with fiber is complex and expensive. The G1000 series of G.hn to Ethernet Managed Demarcation Point devices complement the Positron G.hn Aggregation Multiplexer (GAM) family to deliver near symmetrical Gigabit Internet access to subscribers in MDUs over the existing telephone or coaxial infrastructure at a fraction of the cost of alternatives.

Introducing G.hn

GAM-1000-M+C

The ITU-T G.9960 G.hn Wave-2 standard is designed to leverage the existing telephone wiring (UTP, CAT-3 or CAT-5/5e) or RG-6/RG-59 coax cabling with an access technology that delivers a Gigabit Internet service to each subscriber at a lower cost and without the cost, 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. With G.hn as the Access technology, Operators deliver advanced services such as Gigabit High Speed Residential Internet and 4K IPTV without the high capital and operational expenses associated to 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 G1000 Managed Demarcation Point

The Positron G.hn to Ethernet Bridge (G1000-M for twisted pair or G1000-C for coaxial) is a Managed Demarcation Point acting as a Virtual CPE (vCPE) that can be used to connect to a Residential Gateway (RG) that does not have native support for G.hn on its WAN port.

The G1000-M and G1000-C devices are used to control 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 G1000-C operates under control of the GAM to isolate the traffic from each subscribers that share the same coax splitter.


G-1000 chart

Since the G.hn Access Network operates at layer-2 (same as Gigabit Ethernet and GPON), the G1000-M and G1000-C can operate under a virtual CPE (vCPE) mode when Operators rely on a Virtualized Network Function (VNF) architecture where services such as IP Routing and Firewall are handled by servers in the “cloud”.
