— Print Configuration of DAHDI Spans</p>
<h2>SYNOPSIS
<a name="SYNOPSIS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em"><b>dahdi_scan</b>
<i>[spans]</i></p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em"><i><b>dahdi_scan</b></i>
prints information about DAHDI spans in the system. For
analog spans it also provides a list of channels.</p>
<p style="margin-left:11%; margin-top: 1em">By default it
prints information about all the spans in the system.
However if parameters are provided, they will be considered
to be a list of span numbers and information will be printed
for them.</p>
<p style="margin-left:11%; margin-top: 1em">Output is
printed to the standard output. The format is that of an
Asterisk configuration file (similar to a "ini"
configuration file), where the name of the section is the
number of the span. Note that the specifically for analog
spans some keys may appear more than once, and hence you can
not use a parser for an "ini" format and assume
you have a dictionary.</p>

<h2>BUGS
<a name="BUGS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The program
still does not do everything described in the man page.</p>
<p style="margin-left:11%; margin-top: 1em">It also assumes
that spans don’t skip channel numbers, and that their
channel numbers are "running". This is anyway
almost always the case. And always the case in a normal boot
process.</p>
