Multi-service access nodes (MSANs) : Gateways to next-generation network (NGN)
Brett Handley · Fujitsu Scientific and Technical Journal · 2006
While it is possible to envisage a Next-Generation (NGN) solution with a heterogeneous core, the same cannot be said for the fixed access network. Multiple legacies and new technologies must continue to be supported, delivering the widest range of services and adapting them so they can be carried over the NGN core. This paper considers the range of services and technologies that have to be handled by the access network and how a single solution - the Multi-Service Access Node (MSAN) -can be cost-effectively developed and deployed to meet the challenge of providing an access gateway to the NGN core. It then looks at an MSAN solution called GeoStream Access Gateway that was developed by Fujitsu Telecommunications Europe Limited and chosen by British Telecom (BT) for their 21 st Century Network in the UK.
