<div dir="ltr"><div class="gmail_extra"><div class="gmail_signature"><div dir="ltr"><div>Hi,</div><div><br></div><div>Here are some CA printouts from LM940, MC7455 and EM7565. As can be seen in the MC7455 GSTATUS printout, that without activity the CA will not be active, it seems to "activate" once the data start moving. Which is probably a resource saving thing.</div><div><br></div><div>With the EM7565 I don't even know which CA combinations it support, I guess it must be plenty, but I have no info.</div><div><br></div><div>-Sebastian</div><div><div><br></div><div>Telit LM940</div><div><br></div><div>The CA printout when there are no activities on the modem;</div><div><br></div><div>#
