Clock Source
Additional Information: Clock Source allows you to select either an Internal (ST) or an
External (TT) clock to latch the input auxiliary data (SD). There are three different ways
to configure the clock sources for the SE4000 and a DTE. The following table lists
these different configurations along with the circumstances under which each is used.
n
The first option will produce the most reliable auxiliary data.
n You should use the last option only if you are unable to configure your DTE for
either of the first two options.

Option 1: DTE is able to Internal TT External ST
turn around ST and provide
ST back to the SE4000
as TT.
Option 2: DTE is not able to
External TT Internal Internal
turn around ST, but has an
internal clock that can be
provided to the SE4000
as TT.
Option 3: DTE is not able to
Internal ST External None
turn around ST and does
not have an internal clock
to provide to the SE4000
as TT.
For more information on configuring the auxiliary data channel clock source, refer to the
chapter on installing the SE4000.
