In fact I was rather referring to the previous example in which a
cable did run OK for years and suddenly stopped to.

Obviously, the connector pins were still correctly set.
If it stopped to work, then it must come from the electric signals and
should explained through cable impedance or things like that.

My question was rather how could the replacement cable itself be
precisely described  (thickness, shield, category, ...) ?
