Defines the Path Replacement additional network feature (ANF-PR) which applies to various basic services supported by Private Integrated Services Networks (PISN). This feature is applicable to an established call, permitting the connection of that call between Private Integrated Services Network Exchanges (PINXs) to be replaced by a new connection.
