A system is described for providing ISDN services on a PSTN to communication units from an ISDN interface within a resource controller. The communication unit is allowed access to a target such as a subscriber within the PSTN or a communication unit in another cell, in an ISDN environment through entry of a target access number. The ISDN environment may be changed by the communication unit before entry of a target ID number.
