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?

Paul

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 ..."  :-)
