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
