Abstract
A telecommunications device includes a backplane having an associated high availability backplane environment. A transition card coupled to the backplane helps transition a standards-based card supporting a Peripheral Component Interconnect (PCI) administrative bus into the high availability backplane environment. The transition card may also help transition either a Computer Telephony or a Serial Telephony serial data bus into the high availability backplane environment. In a more particular embodiment, the transition card may support a control bus, a synchronization bus, a reset bus, an isolate bus, and a power bus that each support at least one high availability characteristic not associated with the PCI bus. In another more particular embodiment, the transition card may provide at least some redundancy, hot insertion, fault detection, fault isolation, and fault recovery capabilities not associated with the PCI bus.
