ABSTRACT:
An improved method of providing transparent packet access to a D-channel of an ISDN, includes the step of providing a user packet including an Address field, a Control field and an Information field, for transporting to an ISDN; Extracting the Address, Control and Information fields from the the user packet; and inserting the extracted fields into an Information field of an ISDN format LAPD packet. Preferably X.25 packets are provided access to the network, and the X.25 LAPB Address, Control and Information fields are inserted into the LAPD information field. This method provides independence of protocols and reduces complexity.
