The electronics to accept that amount of bandwidth must be impressive.


What they did with cable, is that the cable arrived at a... I don't know 
the name in English. On one side of a rack, the cables are wrapped on 
pins, thousands of them. At the other side, another pair goes to a 
similar rack, that belongs to each company. So you can easily rewire the 
cable coming from a customer to the exchange, and there route physically 
to the rack of the actual company that supplies phone service to that 
customer.

With fibre it is not possible, because each fibre brings 16 customers 
time multiplexed. It must be software.
