Dedicated Lines

Dedicated lines, also called leased lines, provide full-time service. Dedicated lines typically are used to carry data, voice, and video. In network design, dedicated lines generally provide backbone connectivity between major sites, as well as LAN-to-LAN connectivity. When dedicated line connections are made, a router port (basic devices for dedicated and packet/cell switched technology are routers) 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 selected to connect many sites.
