Sunnyvale, CA — (press release excerpt) — MontaVista Software Inc. announced that Cirpack is currently providing telecom operators with robust voice infrastructure solutions developed using MontaVista's High Availability (HA) Framework. The Cirpack solutions deliver field-proven carrier-class features meeting high availability requirements.

Cirpack develops next generation voice switching equipment for telecom service providers' infrastructure. The Cirpack solutions manage Class-4 and Class-5 telephony services over any type of local loop and core network simultaneously, using IP, ATM and TDM protocols. They are based on an Intel CompactPCI shelf, hosting Cirpack's copper and fiber interface boards. All interfaces and processor modules are hot-swappable, and the systems can be equipped with full redundancy to achieve state-of-the-art reliability.

MontaVista High Availability Framework enables developers to enhance the reliability of their applications by supporting redundant system slot processors to work in active/stand-by pairs (2N) with rapid fail-over from the active to the stand-by CPU. It also supports the in-place swapping out of failed peripheral slot processors by technicians in response to hardware faults. The framework includes key software components needed to support fault-resilient systems, including code that facilitates RSS fail-over, and ready-to-use hot swap 'aware' device drivers and templates for standard peripheral slot CPUs.
