DASS2 Module-Specific Settings
Attribute Value
Clock Primary
Source Secondary
Internal
Designates whether the DTM/BRI acts as a primary or secondary timing component for an
external timing source or as the internal timing source.
Note: A BRI module can be programmed with primary/secondary clock source, however, it
is recommended that a BRI module always be set to Internal if a DTM exists on the system
to be the Primary External clock source.
Warning:
If you change the clock source for your system, you may cause your system DTM
interface(s) to reset, resulting in dropped calls. Choose a suitable time to change the clock
source and use the Page feature to inform users of possible service disruptions.
