Abstract
An arrangement is disclosed for providing station number portability to stations ported from an original switching node to a new switching node which allows the ported station to maintain its original assigned station number. A ported station retains its original assigned number when it's original and new node have a common data base. The common data base identifies what station number is currently associated with which node. The station can be ported from one node to another node by altering the data base to indicate the new association of the ported number and the node to which the station has been ported.
