A query from the moderator re revenue for telecommunications

[David Farber <farber () central cis upenn edu>]

There is a claim by some that as far as traffic volume is
concerned, soon just the traffic from WWW-access will
surpass all the AT&T fax traffic and within 2 years all the
AT&T telephone traffic.


Given that what is the relative revenue for the US carriers from:


telephone local calls:  1 (please pick any catagory as the base)
interlata traffic:
private data traffic non IP:
private data traffic IP:
public traffic IP:


I will summarize and send out. Please note the request is
for relative amounts and for revenue NOT traffic.
