The ATCA-7101 blade providesGigabit Ethernet interfaces tothe PICMG. 3.0 base interfaceand the PICMG 3.1 Option 1fabric interface in a dual starconfi guration. This allows thebase interface to be used forcontrol, signaling, or managementwhile the fabric interfaceis used for high performancedata transport, providingmaximum network scalability. Inaddition, two external, payloadGigabit Ethernet interfacesprovide direct, high performancenetwork access.
