5.2 Router Correction Time and Cascading

The values listed below are typical values and
should fit most system configurations. The va-
lues to be used in a specific system may vary
based on parameters like busload and num-
bers of nodes. The use of a router may require
higher values for the Event Timeout settings.
If cascading is used, the Correction Time will
increase by the values of the following table
for each additional segment.
