The connection is made using the terminals designated TB3-1 to TB3-4 in the Q2 connection box.
The core colors depend on the standard used, normally EIA/TIA 568B. The twisted pairs must not be
untwisted or regrouped. The polarity of the cores within the core pair is unimportant and the core
pairs can even be swapped.
