<h1>Activating Enhanced Quality of Service (EQoS) for testing purposes</h1>

<div class="purpose">
<a name="p2xhtm-repid-2" shape="rect"></a>
<div class="topic">
<h2>Purpose</h2>

<p>The following procedure describes activating EQoS for trialling or testing
purposes using a single PCU2 card.</p>


<p>Activating EQoS requires supported software set negotiations with the
SGSN and a reset of every NSE. If you activate EQoS before creating the Gb
interface, the extra resets are not needed. See <a href="NED?action=retrieve&amp;identifier=dn04111826&amp;edition=1&amp;language=en&amp;coverage=global&amp;encoding=xhtml_1_0&amp;component=data&amp;item=data&amp;pointer=ned_top#ned_top" onclick="sync(this);return true" shape="rect">Activating
Gb over IP</a> for instructions on creating the Gb interface.</p>


<p>Enhanced Quality of Service (EQoS) support in the BSC is controlled
by a licence. For more information on activating licences, see <em>Licence-based
Feature Management</em> in <a href="NED?action=retrieve&amp;identifier=dn04111592&amp;edition=1&amp;language=en&amp;coverage=global&amp;encoding=xhtml_1_0&amp;component=data&amp;item=data&amp;pointer=dec331634541#dec331634541" onclick="sync(this);return true" shape="rect">Overview

<div class="topic">
<h2>Before you start</h2>

<ul>
<li><p>Packet Flow Context (PFC) procedures must be supported by the
SGSN before activating EQoS.</p>
</li>
<li><p>The EQoS licence must be installed in the BSC and EQoS must be
in use.  </p>
</li>
<li><p>A PCU2 card is required before EQoS activation.</p>
</li>
<li><p>The EQoS counters are visible only if the Enhanced Quality of
Service Measurement is activated. For more information, see <em>GSM Measurement
Handling</em> (command group TP).</p>

<p>The PCU negotiates support for the PFC procedures with the SGSN during
the reset. If the procedures are supported by the SGSN, EQoS becomes active
for the NSE.  </p>


<p>The state of the EQoS functionality can change in BCSU restart or switchover
as well. These cause the NSE to reset.</p>

<p>If PFC procedure negotiation is succesful, but SGSN does not support
PFC Flow Control procedures, the alarm 1284 is raised. Lack of the PFC Flow
Control procedures does not prevent EQoS activation, but it may restrict EQoS
functionality. Refer to <em>Failure Printouts</em> for more information
