Genesis’ residential broadband solution, powered by our Access Service Manager (ASM), delivers superfast broadband to homes over existing xDSL networks through a variety of residential access customer premises equipment including the Subscriber Access Node – Residential (SAN-R) and our rings based approach via our Home Access Node (HAN).
Carriers frequently compromise and opt for FTTN/FTTC deployments to reduce fiber installation costs. For longer reach customers in semi-rural and rural areas, broadband speeds are deficient because of the greater distances. This problem for the carriers is further exacerbated by the minimum bandwidth demands now dictated by legislation. They still fall short of delivering new Government-defined capacities in suburban and rural locations.
The ASM based residential solution from Genesis combines DSL aggregation and regeneration technologies into the DSL Broadband Extender (DBE) to increase the bandwidth available in such suburban and rural areas where there are no economically viable solutions to improve service. The combination service including the ASM, DBE and a SAN-R for rural is identified as DSL Long Reach (DLR), uses existing infrastructure and can be delivered at less than a twentieth of the cost of a new fiber build, whilst still enabling revenues from much high bandwidth services.
DLR uses A/VDSL2 regeneration technology to simultaneously increase bandwidth and extend reach. This is achieved in the DBE node by dividing single, long cable spans between the CO or Node and the end customer into much shorter, separate hops. Up to 24 pairs can be regenerated by a single, pole mountable DBE which can be powered either locally or from the CO node or other suitable location using line powering. Long cable spans can use several DBEs in a chain to ensure that the high end-to-end distances do not impact the bandwidth delivered to the customer.
In addition to regeneration, the DBE employs Genesis aggregation technology to combine the bandwidth of multiple pairs between each location. This provides the benefits of statistical multiplexing as well as significantly reducing the impact of a single bad pair on a single user. In addition, each DBE can deliver local bandwidth for a Wi-Fi access point or small cell.
DSL and POTS services are terminated at the home on up to four pairs using the SAN-R. When two pairs or more are utilized for a higher bandwidth service, these are aggregated between the SAN-R and its closest DBE or ASM using Genesis aggregation which works independently from and transparently to any other equipment or technology. This removes the need for specific DSLAMs, operating software versions or complex cable pair routing management.
Genesis’ residential solution utilizes the existing carrier infrastructure reducing time to market making it extremely cost effective and highly profitable for the carrier. Carriers can avoid the huge up-front costs of installing a fiber-only infrastructure and the years necessary to realize a reasonable ROI, which is typically achieved within 12 to 18 months via the Genesis ‘pay as you grow’ deployment model.
The Genesis residential broadband solution delivers fast, high capability broadband, even when the fiber-fed Node or Cabinet is a considerable distance from the home. The diagram below illustrates how DLR can be deployed in fiber, copper, wireless and hybrid technology networks.
