Setting Up a Leased Line
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.
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.
