Excellent, someone who appears to know what they are talking
about.

Let's say the cable installer has finished wiring my new
office LAN according to the specifications/drawings my BICSI
certified designer has created. How can one tell the
installers have installed certified cabling? (as opposed to
cabling tested with a continuity tester) Do they give you a
test report? If so, what should it say on it?

What do you mean console cable? Like a RS-232 cable between
my laptop and the router /switch when configuring them for
the first time?
