For the management of leased lines powerful computer systems with a high degree of availability have to be applied. In this range our engineers developed a system concept of a highly compact computer platform. A 64 bit capable CompactPCI architecture with a SPARC CPU under Solaris 8 has been selected. For optimum connectivity the design supports up to 26 Ethernet ports plus two separate SCSI buses and the specific extensions NVRAM and tempterature monitoring and shutdown. Beside the system concept, Kontron Applications provided the entire driver development, documentation, and certification. As an OEM-partner Kontron Applications delivers the systems after a 100% testing directly to the end customers.
