The present document gives guidance on potential solutions to support the tranmission of Point-to-Point Protocol (PPP)

packets over the D channel of an ISDN access without the need of an X.25 virtual circuit as used and defined in the

[1] IETF, PPP extensions, draft-ietf-pppext-aodi-02: "Always On/Dynamic ISDN (AO/DI)"

[4] ITU-T Recommendation Q.921: "ISDN User-Network interface - Data link layer specification".

For the purposes of the present document, the following term and definition applies:

Always On/Dynamic ISDN (AO/DI): networking service that provides an always-available connection to TCP/IP

AO/DI [1] is a networking service that provides an always-available connection to TCP/IP based services. This service

is provided to ISDN subscribers; an ISDN D channel permanent logical link is established between the subscriber and a

packet handler, a X.25 virtual circuit is then established between the subscriber and his Internet service provider. This

virtual circuit is used to establish an Internet connection, when bandwidth is required for the transmission of Internet
