  This is untrue.

  L2 switches are available today that reliably receive OC-12 SONET

  These can be disaggregated into OC3 ATM pipes that can be fed into
  many routers with proven technology and reliability.  Granted, the
  disproportionality of the edge ckts to the backbone ckts provides
  for interesting flow aggregation dynamics, but it does work.

  Your disdain for ATM does not stop its existence and use by the
  larger NSPs.

  Aggressive statement, though the timbre is occasionally marked by
  usefulness.  I wonder how the world would develop without Sean's
  input.....  {music, clouds, harps... visions of ATM faeries

  There is another router vendor who has OC-12 router interfaces
  about ready for production.  Another (#3) is expected to release a
  bang-up product real soon now.

  There is a choice in the market today for OC12 router interfaces.
