Hi List,
Anyone recalls ever seeing the IOS naming convention document. In particular
I'm interested in differences between families and trains.

This is all I found:

But im looking for something a bit more recent maybe? Can figure out
differences between say SG, SGA, EW and EWA.

A link to the cipher would certainly help.
