Non-volatile storage of operational conditions of integrated access device to facilitate post-mortem diagnostics

摘要

An operational condition capture mechanism within the communications control processor of an integrated access device stores in non-volatile (flash) memory prescribed state information associated with the operation of the communications control processor, in response to a catastrophic event that initiates a reboot of the device, and thereby interruption of the transmission of digital communication signals by the integrated access device, so as to facilitate subsequent off-line analysis (e.g., trouble-shooting) of the cause of the misoperation of the device, and interruption of digital communication service.
