Peter,
congratulations again. -
Could anybody help me a bit with SONET/SDH technology:
what is the present state of - say STM4c vs STM4 etc.-
standardization.
At Stuttgart we run some 20km dark fibre driven by FORE`s
ATM/STM4c boards (NEC SX4 32 - Cray T3E 512) - would
we buy e.g. NORTEL SDH equipment if this would be -
say 100km - and what about public European SDH?
How is vBNS going to upgrade to 622Mbit/s ?
What does the the below "Cisco's Native IP over SDH/VC4"
exactly say?

p.s.: ... if not the telephone system itself- would Christian prepare
an analysis saying "a 600Mio participants Internet of `appropriate`
capacity with RSVP and IPng would allow for concurrent
AUDIO (as Jon said) of phone quality for everybody ..." :-)
