This is not HALON related but it is along similar lines of others on
here.
We had a T1 that worked perfectly AT&T (in the 1980's) said it was
to spec and almost zero errors.
One of my many part time responsibilities was for maintaining the
3725 software. Every so often the T1 (it was muxed) would go zonkers.
I had AT&T and everyone looking at it and they could see it go crazy
and were trying to pin down what was causing it. I had traces up the
ying yang showing the issue but everything (software) was up to snuf
and I had IBM level 2 scratching their heads as they could not see
the issue either. It was getting semi serious as the NP was out
pacing the floor and yelling at people. One of our people was talking
to the people on the other end (NYC) and he made a comment about it
seemed to happen when ever the freight elevator went by......
Turns out they didn't use shielded wiring in the elevator shaft (DAMM
AT&T). They were out and replaced it and really never had an issue
after that and we POURED data through it! Never a software issue (NCP
or VTAM) it was solid as a rock just like good code should be.
