Toolpack allows the system to have a system clock references list. Clock redundancy is accomplished by configuring at least 2 valid clock references in the system.

If the active clock source becomes unavailable, the system will scan through the clock reference list again to find another valid clock source. Clock recovery, which means that the system will switch back to a more preferred clock source if it becomes available again, can be configured in TMS network.&lt;/div&gt;&lt;/td&gt;&lt;td class='diff-marker'&gt;&amp;#160;&lt;/td&gt;&lt;td style=&quot;background: #eee; color:black; font-size: smaller;&quot;&gt;&lt;div&gt;The system clock is configured using the Toolpack web portal.

If your system includes [[&lt;del class=&quot;diffchange diffchange-inline&quot;&gt;TMP7900-&lt;/del&gt;TMS]], it is recommended &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;to &lt;/del&gt;use the [[&lt;del class=&quot;diffchange diffchange-inline&quot;&gt;TMP7900-&lt;/del&gt;TMS]] [[BITS]] ports as clock sources.&lt;/div&gt;&lt;/td&gt;&lt;td class='diff-marker'&gt;+&lt;/td&gt;&lt;td style=&quot;background: #cfc; color:black; font-size: smaller;&quot;&gt;&lt;div&gt;Always place the most reliable clock source at the top of the clock references list in the web portal. This will avoid unnecessary clock switch over. TelcoBridges recommend to synchronize the clock on the BITS port when available. If your system includes [[&lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;7800 &lt;/ins&gt;TMS]], it is recommended &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;that you &lt;/ins&gt;use the [[&lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;7800 &lt;/ins&gt;TMS]] [[BITS]] ports as clock sources.&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

This will avoid unnecessary clock switch over. TelcoBridges recommend to synchronize the clock on the BITS port when available. If your system includes &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;[[TMP7900-TMS]]&lt;/ins&gt;, it is recommended to use the &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;[[TMP7900-TMS]] [[&lt;/ins&gt;BITS&lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;]] &lt;/ins&gt;ports as clock sources.&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

For example, in a system containing 2 TMS1600 ( one will be active the other standby ) the clock sources on the standby TMS1600 (BITS ports) will not be chosen. In the figure below the clock source #3 and #4 won't be selected as system clock unless the standby TMS1600 becomes active.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
&lt;tr&gt;&lt;td class='diff-marker'&gt;&amp;#160;&lt;/td&gt;&lt;td style=&quot;background: #eee; color:black; font-size: smaller;&quot;&gt;&lt;/td&gt;&lt;td class='diff-marker'&gt;&amp;#160;&lt;/td&gt;&lt;td style=&quot;background: #eee; color:black; font-size: smaller;&quot;&gt;&lt;/td&gt;&lt;/tr&gt;
