L
Line Rerouting
A short-term change in the routing of telephone traffic, which can be planned and recurring, or a reaction to an outage situation. Many regional telephone companies offer service that allows a computer center to quickly reroute a network of dedicated lines to a backup site.
Local Area Network (LAN)
A short distance network used to connect terminals, computers, and peripherals under some standard form, usually within one building or group of buildings. A LAN does not make use of public carriers in linking together its components, although it may have a "gateway" outside the LAN that uses a public carrier.
