Then you can just put sync muxes at ends and get three clearline
DS-3s.  Still beats ATM over OC-3. (Of course, RFC-1916 is better).

The pricing on ATM transport is merely an artefact of "pilot"
status of ATM networks.  Carriers lose money on that.  When
market will be established the prices are bound to rise to
that of native IP transport, or, likely, more (as ATM does not handle
levels of overcommitment found in IP backbones now).

IP transport also tends to be overpriced, as revenues are used
to sustain constant build-up (as opposed to capital investments
used to build FR and ATM networks).  That silly kind of accounting
(when growth costs are counted as operational expenses in IP
service) is what i was rallying against in Sprint for quite a
time (that's being fixed, or so i told, now).
