The maintenance subsystem is the part of a system that is responsible for initializing and maintaining the system. This subsystem continuously monitors the condition of the system and records detected errors. The maintenance subsystem also provides a user interface for on-demand testing.

This chapter provides a brief description of the maintenance strategy and presents background information about the overall functions of the system. For detailed descriptions of components and subsystems, refer to related topics in the Avaya Aura® Communication Manager Alarms, Events, and Logs Reference.
