Paul,

Very good explanations!!!

I also felt the reference was making more of an emphasis on Digital packets, rather than explaining an Analog envelope [which as you know is rather complex as compared to a packet].

The reference from Joe is just what Frank needs to use for FDDI LAN tech, so it's probably better on that angle to keep within the Digital / Binary spectrum as opposed to an explanation of complex Analog envelopes.
