ABSTRACT:
In one embodiment, a method to exchange Q-bit data packets between TCP/IP and X.25 devices includes receiving an incoming packet sequence and translating the incoming packet sequence into at least one outgoing packet. A Q-bit indicator in the first packet of the incoming packet sequence is passed to the outgoing packets to indicate control information in the incoming packet sequence. To ensure backward compatibility, the method further includes enabling RBP Q-bit support and disabling Q-bit support by default.
