<div class="body conbody"><p class="shortdesc">Mediatrix devices are supplied with an exhaustive set of documentation. </p>
<p class="p">Mediatrix user documentation is available on the <a class="xref" href="http://documentation.media5corp.com" target="_blank">Media5 Documentation
Portal</a>.</p>
<div class="p">Several types of documents were created to clearly present the information you are looking for.
Our documentation includes:<ul class="ul" id="concept_v4k_q3h_1r__ul_bqy_cjh_1r">
<li class="li"><strong class="ph b">Release notes</strong>: Generated at each GA release, this document includes the known and
solved issues of the software. It also outlines the changes and the new features the release
includes.</li>
<li class="li"><strong class="ph b">Configuration notes</strong>: These documents are created to facilitate the configuration of a
specific use case. They address a configuration aspect we consider that most users will need to
perform. However, in some cases, a configuration note is created after receiving a question
from a customer. They provide standard step-by-step procedures detailing the values of the
parameters to use. They provide a means of validation and present some conceptual information.
The configuration notes are specifically created to guide the user through an aspect of the
configuration. </li>
<li class="li"><strong class="ph b">Technical bulletins</strong>: These documents are created to facilitate the configuration of a
specific technical action, such as performing a firmware upgrade.</li>
<li class="li"><strong class="ph b">Hardware installation guide</strong>: They provide the detailed procedure on how to safely and
adequately install the unit. It provides information on card installation, cable connections,
and how to access for the first time the Management interface.</li>
<li class="li"><strong class="ph b">User guide</strong>: The user guide explains how to customise to your needs the configuration
of the unit. Although this document is task oriented, it provides conceptual information to
help the user understand the purpose and impact of each task. The User Guide will provide
information such as where and how TR-069 can be configured in the Management Interface, how to
set firewalls, or how to use the CLI to configure parameters that are not available in the
Management Interface.</li>
<li class="li"><strong class="ph b">Reference guide</strong>: This exhaustive document has been created for advanced users. It
includes a description of all the parameters used by all the services of the Mediatrix units.
You will find, for example, scripts to configure a specific parameter, notification messages
sent by a service, or an action description used to create Rulesets. This document includes
reference information such as a dictionary, and it does not include any step-by-step
procedures. </li>
