Abstract
A network interface (105) uses valid identifiers including the DN, SPID and Switch ID to communicate with a PSTN (110) and uses generic identifiers to communicate with customer premise equipment (120) in order to establish an ISDN communication link when the customer premise equipment does not know the DN, SPID, and Switch ID.
