Thanks to everyone who has responded to my e-mail.

The documentation doesn't really explain it that well.

This is what I have picked up from the conversation:

Using these settings, The T100P would get Clock Sync from itself.  It would
use its own timing.

span=1,0,0,esf,b8zs

Using these settings, the Channel Bank will receive clock sync from the
t100p.

span=1,1,0,esf,b8zs

Sorry for my stupidity, and it seems as this thread always comes up about
once a year, however it really hasn't been fully explained.  It just seems
as if there is only two methods of operation.  Either don't use the span as
a timing source (e.g. the CB and t100P provide their own timing, or the
other method, the T100P provides clock sync.)  Is it possible for the
Channel Bank to retrieve clock sync from T100P?

Thanks,
