CDR generates alarms when detecting problems with recording on an entity for which CDR is enabled. These alarms indicate that call accounting for the entity is not available. During the outage, some or all calls are not recorded in CDR.

The alarm must be cleared manually after the failure condition is resolved.

An example of an alarm message is: There is a problem with the Call Detail Recording (CDR) system. Call accounting is not operational.

An example of text when the alarm has been cleared is: Call Detail Recording (CDR) system is now operational. Call accounting is resumed.
