Setting Up a Leased Line (Task Map)

Leased-line links are relatively easy to set up, in comparison with dial-up links. In most instances, you do not have to configure the CSU/DSU, dialing services, or authentication. If you do need to configure the CSU/DSU, refer to the manufacturer's documentation for aid with this complex task.

The task map in the next table describes all the tasks that are involved in setting up the basic leased-line link.

Note –

Some types of leased lines do require the CSU/DSU to “dial” the address of the opposite peer. For example, Frame Relay uses Switched Virtual Circuits (SVCs) or Switched 56 service.

4. Configure information about the remote peer 

Define how communications between your local machine and the remote peer should work.

5. Start up the leased line 

Configure your machine to start up PPP over the leased line as part of the booting process.
