A note about Figures 22 and 23: The ATM Forum and ITU-T standards 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.
NOTES:
1. No power or ground plane inside this area.
2. Analog power plane inside this area.
3. Digital power plane inside this area.
4. A single ground plane should extend over the area covered by the analog and digital power planes, without breaks.
5. All analog signal traces should avoid 90° corners.
