In the most basic configuration, you can create a LAN between a CMS server and a Communication Manager system using either a crossover cable or a dedicated hub. This setup provides isolation from the customer data network, keeping all Communication Manager system-to-CMS messaging traffic on a dedicated private network. The CMS server is directly connected to the Communication Manager system, and neither is part of another network.

This configuration is adequate if there is no printer or CMS Supervisor traffic.
