The Overload Profile specifies a set of congestion thresholds, congestion durations, and overload controls. When a particular threshold is exceeded for a particular duration for any of the call processing related processes, the congestion level is raised to a higher level and the overload control is applied to help alleviate the congestion. The profile also specifies clear congestion thresholds and durations.
These values require that the overload conditions fall below their configured clear threshold values for a specific duration in order to return to the previous congestion level. These minimum clear durations prevent repeatedly switching in and out of congestion levels. You may assign an Overload Profile to the system (and apply it throughout the

). You may specify and manage the following congestion criteria through this facility:- CPU utilization
- Memory utilization
The following default Overload Profiles are automatically created for system congestion levels 1-3:
- defaultMC1
- defaultMC2
- defaultMC3
You must disable an Overload Profile in order to change its configuration. Then, when you enable the profile, you cause all the parameter values to be validated. Once validated, these values are applied to the (system) congestion level that references the profile. When you make a change in this manner, the system congestion level is cleared if the Overload Profile was being referenced. Standby modules also perform congestion processing but you cannot configure the module settings.
