In the early 60's a friend got transferred to N.J to help in ESS
development work. I remember him mentioning one, ahem, minor problem
that kept recurring.

Seems the switch would be all up and happy, but when REALLY busy, for
some reason it would 'forget' about some calls already in progress.
They were still talking, but when the switch went to use the
?connector/level or whateever they called it? and found it "occupied"
it got upset.

The only way to pacify it was to let it restart. In other words, knock
down EVERY call in the switch and start at zero.

Glad they fixed THAT one before installation. Can you imagine the mess
of rebooting the biggest tandem switch in NYC or Chicago at ten AM? On
a regular basis?
