It's been a week now, so I feel a little less apt to rush to a possibly
incorrect judgement. I'd been having recurrent but intermittent problems
with the 56kb serial line in the 2 weeks since I installed a CGS/2: thousands
of carrier transitions and hundreds of serial interface resets, making the
line virtually unusable. The telco repeatedly reported that their line was
clean. Shortly thereafter, the power supply on the CGS/2 died, and I received
a new power supply by FedEx the next day. After replacing it, I haven't
had any problems whatsoever--in the past week, one or two interface resets
and carrier transitions.
While I can't be absolutely sure, it may be that the power supply was flaky to
begin with, and had its most obvious pre-failure effects on the stability of
the synchronous serial line. At least that's my current voodoo explanation.
