<h2>Purpose</h2>

<p>If the AMR-capable pool is no longer needed, remove it
as instructed in <em>BSS Integration</em>, section <em>Creating the
A interface</em>, but in the reverse order. Alternatively, you can modify
the AMR pool as instructed in <a href="NED?action=retrieve&amp;identifier=dn02211272&amp;edition=3&amp;language=en&amp;coverage=global&amp;encoding=xhtml_1_0&amp;component=data&amp;item=data&amp;pointer=nov252136191#nov252136191" onclick="sync(this);return true" shape="rect">Activating
Adaptive Multi Rate Codec (AMR) in BSC</a>.</p>


<p>Telecom support for AMR is switched off with the feature-specific
control parameters. The parameters become valid after five minutes, therefore
a five-minute delay is needed before testing the deactivation.</p>
