Introduction to ATCA ? UTS ATCA Product Overview ? ATCA Platform Application Introduction to ATCA What does ATCA deliver? ? Scalable capacity to ? Multiprotocol support for interfaces up to 40Gb/s ? High levels of modularity and configurability ? The ability to host large pools of NPUs, processors, and storage ? Convergence of tele access, core, optical, and datacenter functions ? Advanced software infrastructure providing APIs and OAMamp。P ? Worldclass element cost and operational expense ? A healthy, dynamic, multivendor, interoperable “ecosystem” Why don?t existing standards meet these needs ? Board areas are too small for emerging applications ? Board spacing is too narrow ? Heat dissipation is inadequate for next generation semiconductors ? Backplane capacity is limited ? Signal integrity and electromagic patibility are being problems ? Mechanical standards don?t support I/O requirements ? Power distribution systems need modernization ? Hardware management is ofte
