Dear Co-Group members, I am confused why have people given two bit (that too separately) in the address field in both ISDN and Frame Relay. Basically the 1st of the two Extended Address bits if sets allows a extended addressing but what happens to the2nd EA bit? Why do they have this extra provision? Any specific reason's? Anyone has any answers?
