<p>
Modem enabling is the user-requested sequence with the sole purpose of bringing
the modem to a state where it can get connected.
</p>
<p>
As with the initialization sequence, the global enabling sequence is itself
splitted into N per-interface enabling steps (being N the number of interfaces
exported by the modem). Those interfaces implemented by the object but not
supported by the modem will not be enabled.

<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p><span class="emphasis"><em>Modem interface enabling</em></span></p>
<p>
The sequence to enable the
<a class="link" href="gdbus-org.freedesktop.ModemManager1.Modem.html" title="org.freedesktop.ModemManager1.Modem">Modem interface</a>
takes care of different important steps, such as <span class="emphasis"><em>powering up the
radio interface</em></span> or <span class="emphasis"><em>configuring</em></span> the best charset
to use.
</p>
</li>
<li class="listitem">
<p><span class="emphasis"><em>3GPP interface enabling</em></span></p>
<p>
Modems with 3GPP capabilities will enable the
<a class="link" href="gdbus-org.freedesktop.ModemManager1.Modem.Modem3gpp.html" title="org.freedesktop.ModemManager1.Modem.Modem3gpp">3GPP interface</a>
as part of the global enabling sequence. This sequence involves setting up the
<span class="emphasis"><em>automatic registration</em></span> of the device in the network, as well
as configuring 3GPP specific <span class="emphasis"><em>indicators and unsolicited message
handlers</em></span>.
</p>
</li>
<li class="listitem">
<p><span class="emphasis"><em>CDMA interface enabling</em></span></p>
<p>
Modems with CDMA capabilities will enable the
<a class="link" href="gdbus-org.freedesktop.ModemManager1.Modem.ModemCdma.html" title="org.freedesktop.ModemManager1.Modem.ModemCdma">CDMA interface</a>
as part of the global enabling sequence. This sequence involves setting up the
<span class="emphasis"><em>periodic checks of registration</em></span> in the CDMA network.
</p>
</li>
<li class="listitem">
<p><span class="emphasis"><em>Additional feature-specific interface enablings</em></span></p>
<p>
Each feature-specific interface will have its own enabling sequence, with operations
which are directly related to the purpose of the interface. For example, enabling the
<a class="link" href="gdbus-org.freedesktop.ModemManager1.Modem.Location.html" title="org.freedesktop.ModemManager1.Modem.Location">Location</a>
interface will involve setting up the initial location information; and enabling the
<a class="link" href="gdbus-org.freedesktop.ModemManager1.Modem.Location.html" title="org.freedesktop.ModemManager1.Modem.Location">Messaging</a>
interface will involve loading the initial list of SMS available in the SIM or Modem.
