We have resolved the issue - it turned out that there was something
wrong at the SL100 side of the connection.  The bad news is that I
can't get anyone who manages that SL100 to tell me exactly what
the problem actually was.  The best I was able to get was, "It was
some kind of cable or configuration problem."

The only private feedback I got were recommendations to try the
Sangoma cards (it looks like they keep more in the way of statistics).

I also have no idea why the TE410P complained, but the Cisco AS5350
didn't.

Thanks to everyone who provided feedback.
