According to figures that were presented at the Gigabit Networks
conference in Washington, D. C. today, AT&T handles roughly 130 million
calls per day. If each of these calls lasts an average of five
minutes, the total necessary bandwidth for all AT&T handled long
distance calls is roughly 20Gb/sec.
Add to this all local calls, and calls handled by other LD carriers,
and I think you've got an impressive bandwidth requirement.
