&lt;p&gt;Here is the answer I got from the modem team:&lt;/p&gt;
&lt;p&gt;&lt;em&gt;RLC Unack mode is optional for Cat-M devices and we don&amp;#39;t have official support for it. &lt;/em&gt;&lt;br /&gt;&lt;em&gt; This CMW-KS510 license enables possibility to change RLC mode from RLC Unack to RLC Ack mode. &lt;/em&gt;&lt;br /&gt;&lt;em&gt; The default option in R&amp;amp;S callbox is RLC Unack and to change it CMW-KS510 license is required.&lt;/em&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Connection disconnection problem on a CMW290 in LTE</title><link>https://devzone.nordicsemi.com/thread/405501?ContentTypeID=1</link><pubDate>Wed, 18 Jan 2023 14:12:17 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:942f2335-29f2-467d-8c5d-faae7c31566f</guid><dc:creator>Didrik Rokhaug</dc:creator><description>&lt;p&gt;I&amp;#39;ll have to check with our modem team, as they are more familiar with the callboxes.&lt;/p&gt;
&lt;p&gt;I&amp;#39;ll let you know when I get a reply from them.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Connection disconnection problem on a CMW290 in LTE</title><link>https://devzone.nordicsemi.com/thread/405392?ContentTypeID=1</link><pubDate>Wed, 18 Jan 2023 08:43:38 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:afddff9f-7338-47fc-ad2f-58ba4eeb3605</guid><dc:creator>EMT</dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;
&lt;p&gt;Thank you for your reply.&lt;/p&gt;
&lt;p&gt;&lt;span class="HwtZe" lang="en"&gt;&lt;span class="jCAhz ChMk0b"&gt;&lt;span class="ryNqvb"&gt;With the CMW290 settings and the KS510 license, it works now.&lt;/span&gt;&lt;/span&gt;&lt;span class="jCAhz"&gt;&lt;span class="ryNqvb"&gt; &lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span class="HwtZe" lang="en"&gt;&lt;span class="jCAhz ChMk0b"&gt;&lt;span class="ryNqvb"&gt;However, why for other manufacturers of NB-IOT &amp;amp; LTE modules there is no need for this license?&lt;/span&gt;&lt;/span&gt;&lt;span class="jCAhz"&gt;&lt;span class="ryNqvb"&gt; &lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span class="HwtZe" lang="en"&gt;&lt;span class="jCAhz ChMk0b"&gt;&lt;span class="ryNqvb"&gt;To try to understand, what does it allow to do this license on the nr9160 module?&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span class="HwtZe" lang="en"&gt;&lt;span class="jCAhz ChMk0b"&gt;&lt;span class="ryNqvb"&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span class="HwtZe" lang="en"&gt;&lt;span class="jCAhz ChMk0b"&gt;&lt;span class="ryNqvb"&gt;Thank you.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;Have you seen this blog post?&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;a href="https://devzone.nordicsemi.com/guides/hardware-design-test-and-measuring/b/nrf9x/posts/using-nrf9160-against-r-s-cmw500-or-cmw290-in-signalling-callbox-mode"&gt;Using nRF9160 against R&amp;amp;S CMW500 (or CMW290) in signalling callbox mode&lt;/a&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;What application are you running on the nRF9160?&lt;/p&gt;
&lt;p&gt;What SIM card are you using? CMWs typically require a Rhode &amp;amp; Schwarz test SIM.&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;
&lt;p&gt;Didrik&lt;/p&gt;
&lt;p&gt;P.S. Due to holiday vacations, responses might be slower than normal. We apologize for the inconvenience.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
