Dedicated lines, also called leased
lines, provide full-time service.
Dedicated lines typically are used to carry data,
voice, and occasionally video. In data network design, dedicated lines
generally provide core or backbone connectivity between major sites or
campuses, as well as LAN-to-LAN connectivity. Dedicated lines
generally are considered reasonable design options for WANs.
When dedicated line connections are
made, a router port is required for each connection, along with a CSU/DSU
and the actual circuit from the service provider.
The cost of
dedicated-line solutions can become significant when they are used to
connect many sites.
