Sprint upgrades network to SONET
Kansas City, Mo. - Sprint last week announced that it is embarking on a
$350 million, 30 month plan to convert all of its line to SONET
(Synchronus Optical Network) OC-48 level. Once installed, the network
will provide a bandwidth of up to 2.4 gigabits per second (Gbps),
although development work already is under way to increase the bandwidth
to 10Gbps.
The program, which was begun late last year, is expected to be completed
by 1996. Sprint says the upgraded network automatically will double its
potential capacity, but the addition of Asynchonus Transfer Mode (ATM)
technology will further increase the system's load.
Sprint is incorporating a double-ring technology that protects against
network failures, says Anthony Alotto, director of technology and
architecture integration. If a segment of the ring fails, the signal
automatically is rerouted to a ring going in the opposite direction so
that every node on the ring is accessible from reduntant networks rings,
he says.
