yes, for Australia, certainly. A number of us were using E1 inverse  
MUX units to pull higher channel rates out of the circuits. Same thing  
happened a few years later with muxing up 155Mbpsd circuits.

heh heh - we ran out of cable capacity before we ran out of cascading  
inverse muxes at the time! Satellite really was a very inferior choice.

The original telegraph circuits in the latter half of the 19th century  
were largely overland, but, unless there are markets you want to  
intercept with in the middle, undersea tends to be a better option  
where you consider all aspects (territorial rights, political issues,  
total length, stability etc etc). There was a very informative article  
by Neal Stephenson in Wired some years back that was published at  
about the time FLAG was being constructed which still is about the  
best article on the submarine cable business I've read. Everyone  
interested in this submarine cable game except Joe should read it.

The problem with the routes in that part of the word include: the  
Wallace line, territorial waters, shallow waters, the Luzon strait,  
the stability of overland segments, the size of the markets in the  
middle, the cost and availability of the alternatives, and the major  
factor that spending 100% of your investment money to optimise 80% of  
your traffic needs makes more sense than many other investment  
strategies - hence the outcome that the Pacific has become the heavily  
favoured route for submarine cable systems in this area of the world.

nah - more fun to watch you speculate Joe.
