Abstract

A switching module capable of sending heartbeat messages and identifying other elements within a telecommunications switching platform as operational over one bus or both buses of a redundant-pair control bus. The module also has a reprogrammable, nonvolatile memory associated with it from which it can run its operating system. The module can also transfer the operating system into another memory, allowing the module to make updates to the operating system stored in the nonvolatile memory without interrupting its execution of its run-time operating code.
