For xDSL Broadband Deployments
Many service providers chose fiber to the node network (FTTN) architectures that couple optics and copper for maximum advantage – rapid deployment, lower cost, and extremely high-speed performance. In these scenarios, VDSL is increasingly implemented as the last mile connection because it can deliver 100 Mbps throughput and support for expanding service offerings to like triple- and quadruple-play applications.
Residential gateways in these installations must be extremely robust – able to withstand the effects of near-end and far-end cross talk through the use of vectoring technology – to minimize disconnections and maximize quality of service.
Beyond the standard residential gateway requirements, the must-have features of these residential gateways include:
- xDSL Standards Support – G.99x, G.993.5 (g.vector) and others
- Robustness and Noise Immunity – support the latest enhancements such as Rapid Rate Adaptation (RRA),
- Retransmission, Impulse Noise Protection, etc.
- xDSL Performance – 100 Mbps symmetrical connection rates at distances that allow service providers to deliver
- Integration – provide cost effective solutions by integrating the processor with the xDSL data pump
- Power Management – support low power modes during periods of limited data transfer
- Platform Commonality – ability for the operator to use the same processor and software platform for all their customer premises equipment.
