<<DSL technology was developed to help telephone companies carry video programs
over their
traditional copper telephone lines at speeds up to 8 million bits of data per second
(compared with
today's computer modems, which operate at a top speed of 56,000 bits per second).
Phone companies,
including Bell Atlantic Corp., quickly found that the costs of equipping homes for DSL
video signals
exceeded the demand for such a service.
But the rise of the Internet opened a new use for DSL. In 1996, Bell Atlantic began
new market tests
using digital subscriber lines for high-speed Internet access in Northern Virginia.
Trial users had a service through which they could breeze through pages on the World
Wide Web like
leafing through a book --for about $ 50 a month, including Internet service provider
fees. Users could
talk on the phone while surfing the Web and, in fact, they no longer had to "dial up"
their Internet
provider at all, because DSL offers a continuous, 24-hour connection.>>
considering the fact that T1 (1.54 Mbits/sec) such as frame relay, low-speed ATM costs around thousands of $$ per month range for bisiness; so, if this really can go into real-life with the substained throughput for business environment, will be interesting as there will be no room for profit for SPs, telcos, RBOCs, .. and probably won't have much incentives for them to buy network equipments either. |
