Magnetics Modules for 25 Mbps
A note about Figures 22 and 23: The ATM Forum and ITU-T stan-
dards for 25 Mbps ATM define "Network" and "User" interfaces. They
are identical except that transmit and receive are switched between the
two. A Network device can be connected directly to a User device with a
straight-through cable. User-to-User or Network-to-Network connections
require a cable with 1-to-7 and 2-to-8 crossovers.
