I never cease to be amazed by assertions of how easy it is to
manage production level operations over the US using new
technology which is unproven!!!

Just to bring a bit of facts to some of the discussions.
When the DS3 network started , DS 3 routers were not easy to build
--
they still are hard. IBM did a fine job of doing that!! We can mayb
e
do better now but that's now!!
Maybe, I don't understand all the intricacies, but I am puzzled at the
assertion that DS3 routers are hard to build.
DS3 is a 45 megabit service. Several vendors have been selling for
several years ethernet/token ring/fractional T1 routers which can
handle aggregate bandwidths of approximately 100 Mbs. Well, taking
4lan interfaces off of one of these boxes and installing a reasonable
serial interface which can handle T3 speeds should produce a quite
good DS3 router. There is no obvious reason why the government had to
provide IBM, which is not a router company, with its own private test
bed for router development at government expense. An open bid would
have made more sense.
