<div><p>The Communications Summary section of the System Report shows the
use of the communications lines and processors.</p>
<div class="example"><h4 class="sectiontitle">Example</h4><div class="note"><span class="notetitle">Note:</span> The line utilization in the sample system
report shown does not correspond with the "Component Report - IOP Utilizations"
for an IOP running SDLC remote work stations. A low SDLC line utilization
value results in a high IOP utilization value due to polling. However, because
the SDLC line transfers a larger percentage of user data, an IOP polls less
frequently. Usually this results in an overall increase in IOP utilization.
In some cases, though, especially when the SDLC lines have a
low utilization, this results in an overall decrease in IOP utilization. Thus,
a high IOP utilization value is significant only if at least one of the attached
SDLC lines is active.</div>
<p>The values that display in the report header
reflect the configuration metrics obtained from the QAPMCONF file when the
collection started. These values might change for each interval within a collection
period due to dynamic changes in logical partition configuration.</p>
