As Matt pointed out, the paragraph 4 of section 4.2 Framing was badly
mangled. It should read:

Consider a network pipe at 10 Gbps x 200 msec holds 250 MB. [Assume
land-based communication with a spot half way around the world at the
equator.  Ignore additional distance due to cable routing.  Ignore repeater
and switching delays; consider only a speed-of-light delay of 5 microsec/km.
The circumference of the globe at the equator is approximately 40000 km (we
need to consider round-trip delay to keep the pipe full).  10 Gb/sec x 40000
km x 5 microsec/km x B / 8b = 250 MB].
