Abstract
A distributed control switching system where the system control units cooperatively perform the terminating port determination function. The partial results obtained when a first control unit is unable to fully determine the terminating port are advantageously used by the second and subsequent control units such that time-consuming database access tasks are not unnecessarily repeated.
