AdvancedTCA® (Advanced Telecommunications Computing Architecture) is an open industry standard, developed by PICMG® 3.0, to create a new blade (board) and chassis (shelf) form factor, tailored to meet the needs of the rapidly changing communications network infrastructure, and next generation communication applications, which cannot be served by existing proprietary solutions. This architecture places high priority on cost effectiveness versus attempting to support a variety of potential future technologies, at the expense of cost and complexity.
While the specification is founded on the requirements of the communications infrastructure, it is extensible to a variety of applications and environments where highly available, highly scalable, cost effective and open architecture modular solutions are required.
The architecture is optimized around connectivity requirements of signaling and media gateways, while also providing headroom for higher performance computing elements at a 99.999% availability rate. ATCA offers a scalable backplane environment that supports a variety of standard and proprietary fabric interfaces, robust system management, and superior power and cooling capabilities.
