SONET NETWORKING TRENDS
Increases in demand for services such as non-switched private lines mean more
and more T1 multiplexers (intelligent channel banks) are being deployed by large
end users. Some are now implementing T3 (DS-3) fiber services to meet these
demands.
ISDN and Broadband ISDN will allow a multitude of new services to provide
bandwidth on demand. Users of an integrated services network, which offers
voice, data, and video onto a single network, have new requirements including
variable bandwidth, high bandwidth, user control, measurement of traffic performance,
and rapid service provisioning. To provide the necessary bandwidth, fiber
has been deployed increasingly in the access area (connections between a service
provider’s node and the user).
