That leaves us with the throughput of two DS3 links. It doesn't seem worth
the effort given how short term a solution it is.

I am not sure I follow your arithmetic. The line rate on a DS-3 is
44.736 Mbps. You need to subtract several overheads from that: at
least some DS-3 and some PPP overhead.

How does that add up to half of the throughput of an OC-3c IP/ATM link?

As long as I took this opportunity to inquire, what to you mean by
"given how short term a solution it is?"
