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.
Perform the following tasks that when setting up the basic leased-line line:
Information to Gather for the Leased-Line Link – Gather data that is needed prior to setting up the link
How to Configure Synchronous Devices – Assemble the CSU/DSU and synchronous interface card
How to Configure a System on a Leased Line – Define how communications between your local system and the remote peer should work
How to Configure a System on a Leased Line – Configure your system to start PPP over the leased line as part of the booting process
