The document categorizes various alarm names and indicates whether they impact services or not. Most alarms are categorized as external alarms or issues related to hardware problems, misconfigurations, transmission errors, or cell/service interruptions. Only a few alarms such as active workspace version unavailable, ALD maintenance link failure, and carrier configuration error are identified as impacting services due to misconfigurations or software issues.
