<p class=MsoNormal><span style='color:#1F497D'>SDL links are used between CCM,
CTI, and CMI services to share data regarding the current status of devices and
to send calls to and from different nodes in the cluster. They form a full mesh
between like and dislike services. I.E. CCM on node 1 will have an SDL link to
CCM on node 2 and to CTI on node 1 and 2 and so on.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>SDL links going out of service
usually represent a network outage between the nodes or a service crash on one
of the nodes. Any core files in RTMT?<o:p></o:p></span></p>

<div>
<p class=MsoNormal><span style='color:#1F497D'>My RTMT reported the SDL Link
out of service between two of my CCM servers (servers at different
locations). <o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>Not entirely sure what SDL Link
is or does and more importantly, how to determine if it is back up.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>I do not appear to be having CCM
problems anywhere in the environment; just wondering if anyone could offer some
cliff notes on the SDL service <o:p></o:p></span></p>
