<h1 class="topictitle1">Example: Connect the server to itself</h1>
<div><p>This example connects your system to itself. That is, the tokens
travel around the local token ring network before returning to your system.</p>
<p>You can do the example to test an application within your
system before testing it in the network. Because all the examples
use the same token-ring line description, this example discusses only the
controller and device descriptions.</p>
<p>Two sets of controller and device descriptions connect your system to itself.
The first set <a href="rzajudialmode.htm#dial_mode">dials</a> (initiates)
a connection request, and the second set <a href="rzajuanswermode.htm#answer_mode">answers</a> (accepts)
the connection request.</p>
<p>In this example, focus on these points:</p>
<ul><li>Use a different source service access point (<a href="rzajuhigherlayersoverlanprotocols.htm#higher_layers_over_lan_protocols__ssaps_and_dsaps">SSAP</a>) for each controller.</li>
<li>Use the same adapter address in both controller descriptions.</li>
<li>Use dial mode in one controller description and answer mode in the other.</li>
</ul>
<p><strong>Dial command set:</strong></p>
