This throttle includes the Normalization Interval , Max Number to Normalize , and the Settling Interval configuration parameters. The Normalization Interval parameter is the time between attempts to normalize connections. The Max Number to Normalize parameter is the maximum number of connections per normalization attempt that can enter the normalized mode. The Settling Interval is the time after a trunk failure during which no normalization attempts are made. This gives all nodes a chance to reroute without competition by the adaptive voice feature for trunk bandwidth.
Normalization is simply a marginal improvement over an already high-quality voice connection.
The maximum number of connections that may be routed in a single attempt is configured with the Maximum Routing Bundle configuration parameter. Routing many small connection bundles has the effect of smoothing routing work over a longer period of time. Better load balancing is also a benefit with small bundles. Trade-offs Connections in excess of the bundle size that requires routing are delayed. This may be okay with some connection types.
