Fujitsu Targets Wireless Operators

Releases a new, scaleable transport switching solution for wireless carriers

NEW ORLEANS –– Fujitsu Network Communications Inc., a leading supplier of IT and wireline/wireless networking solutions, today announced a new, scalable transport switching solution for wireless carriers. The strategy is based on the highly-flexible and field-proven Fujitsu FLASHWAVE® 4500 Multi-Service Switching Platform (MSSP), which offers the benefits of a Digital Cross-connect System (DCS) without the cost and scalability issues that hinder existing solutions. The platform can be justified for a wide variety of switching requirements in Mobile Switching Centers (MSCs) of all sizes, matching capital investment with today’s traffic demands and minimizing risks.

Current DCS solutions are designed for massive switching requirements, but few MSCs require this capacity. As a result, wireless carriers accepted the high power, space, and cost requirements of stripped-down DCS variants because no other solutions were available. Today, these carriers are discovering that growing their DCSs to handle increasing traffic demands is not as easy or cost-effective as initially promised. Frequent software upgrades and ongoing maintenance issues are costly and time-consuming, and adding extra capacity can be a complex process. High capital and expense costs have also made a DCS prohibitive for most remote Base Station Controller (BSC) sites and many smaller MSCs. The resulting DS1/DS3 multiplexing equipment and manual cross-connections by patch cords have created a cabling nightmare and added thousands of potential failure points to the network.

Fujitsu has solved these limitations with the FLASHWAVE 4500 MSSP. Wireless carriers can start with a single-shelf FLASHWAVE 4500 configuration with a 45G or 70G STS switch fabric and 20 interface slots to meet the traffic demands in smaller MSCs. Later, when traffic demand grows, a larger switch fabric can be added to allow a single shelf to offer 100G service capacity. When additional interface capacity is required, a second and third shelf can be added to expand the system to 40 interfaces and 200G capacity or 60 interfaces and 300G capacity. Three shelves can fit in a single rack and all upgrades are non-service-affecting, making this the easiest capacity upgrade available.

“A typical DCS deployment requires carriers to install a completely new network element and incur a significant capital investment, critical long-range planning expense, and the overhead of supporting yet another network element,” said Dana Cooperson, group and program director of optical networking at RHK, a leading independent telecom research firm. “As the market leader in the North American SONET market with a 28% share (per our research), Fujitsu has provided carriers with an alternative to the DCS that allows grooming capacity to be added as needed, lowering short term capital expense and risk.”
