Oh, it definitely could be something else!  Losing discipline due to 
poor reception was just my guess from afar based on the 
familiar-looking failure and recovery pattern shown in your 
plot.  Losing discipline for any other reason would probably look similar.

As far as failing quietly, if you have both a Ref1 and Ref0 
operating, perhaps the infamous interconnect cable is not working 
properly and is preventing some status displays?  (Or maybe it's 
actually causing the problem?)  And if you are operating just the one 
unit, perhaps the kludge that fools it into working is preventing 
some status displays?

Full disclosure:  I don't have any of the Lucent boxes, so none of 
this is based on hands-on experience.

Best regards,
