In California, Pacbell announced in November 93 that it will use ATM (optical fibre) as a trunk information line and then use (existing) cable to reach groups of 500 customers |
ATM will support very high speeds measured in endless gigabits/sec., but actually traffic is a lot of little messages (as on our vehicle highways) |
A Bandwidth of N gigabits will be ~ 100N messages at 10 megabits/sec. |
