Abstract

A communication switching system comprised of (a) apparatus for receiving dialed digits relating to a call, (b) apparatus for storing a table of groups of initial digits and for each group of initial digits storing a subtable, each subtable being comprised of a list of quantities of digits expected to follow a corresponding group of initial digits, each quantity being correlated with a communication route, each list of quantities of digits being sorted in ascending order, (c) apparatus for selecting a group of initial digits in the table corresponding to first digits of the dialed digits, and for pointing to a communication route corresponding to a lowest quantity of digits in a subtable of selective group of initial digits, (d) apparatus for using the communication route for completion of the call in the event the dialed digits contain a quantity of digits corresponding to the lowest quantity of digits, (e) apparatus for detecting a dialed digit in excess of the quantity of digits and for pointing instead to a next highest quantity of digits in the subtable of the selected group of initial digits, (f) apparatus for repeating step (e) until no dialed digit is detected which is in excess of a highest quantity of digits pointed to and using a corresponding communication route listed in the subtable for completion of the call.
