■ Before testing the splitter, insert a modular
RJ45 plug into jack J1 and jack J2.
NOTE:
Do not connect port J1 to port J2. Leave
the other end of both cords free, because
the modular RJ45 plug acts as a opening
plug and removes the 100-Ω termination
from J1 and J2 ports.
■ After testing is complete, remove the
opening plugs from J1 and J2.
