Are people still building SONET networks from scratch?

The "once-in-a-lifetime" that happened here (took a while though) was WAN 
PHY for 10GE. All the benefit of SDH at Ethernet cost.

When I approached the 40GE/100GE working group about getting a few of the 
benefits of this into that standard, I was instantly shut down by people 
who thought WAN PHY was a huge mistake that shouldn't be repeated.

The only thing I wanted was to have frames sent all the times so one would 
get a basic bit error reading, plus having the PHY send some basic 
information such as "I am seeing light and my world looks ok", so we could 
get PHY based interface-down when there was a fiber cut.

But that wasn't to be, so the only way to get this will be to OTN-frame 
the whole thing I guess. *sigh*
