Title: Determining overall length with thick and thin cabling mix
Date: 08/11/88

I'm using a mixture of thick and thin Ethernet.  Is there some
kind of formula I can use to determine overall length?

A.  The formula is  T + E <= 1000.

          T = Length of thin, measured in feet

          E = Length of thick, measured in meters

Do NOT mix thick and thin more than twice in one segment due to
reliability considerations.
