The Emerson/Motorola CPX8216 is a 12U carrier-grade cPCI chassis engineered for high-availability telecom infrastructure. Built on a dual 8-slot CompactPCI backplane architecture with optional H.110 bus support, this platform delivers five-nines availability for mission-critical deployments. NEBS and ETSI certified, the CPX8216 has powered thousands of global installations since 1999 across media gateways, packet data gateways, media routers, voice messaging, and VoIP systems.
