Which Communication Manager Reset level takes less than 10 seconds and preserves stable calls as well as Error and Alarm logs?

The correct choice reflects the specific function of Reset System 1 in the Avaya Communication Manager environment. Reset System 1 is designed to perform a quick reset of the system, typically taking less than 10 seconds to execute. This reset type is particularly important for maintaining the stability of active calls, as it does not disrupt ongoing conversations. Furthermore, it preserves critical operational data such as Error and Alarm logs, which are vital for system diagnostics and troubleshooting.

The functionality of Reset System 1 allows system administrators to quickly refresh the Communication Manager without losing valuable call information or experiencing significant downtime. This is a crucial feature for maintaining service continuity and providing optimal user experiences.

In contrast, the other reset levels either take longer or do not provide the same level of preservation for active calls and logs, making them less suitable for scenarios where stability is paramount. Understanding the nuances of these reset levels helps in effectively managing the Avaya system and ensuring high availability.
