Unknown—Indicates the tester has detected impedance
outside of the ranges stated for Open and Short faults, or that
the cable is properly terminated into another Ethernet port.
Unknown does not necessarily indicate that a fault was
detected.
Table 19 describes the results that appear in the Cable Status
category.
NOTE:
If the far end of the cable is connected to a powered down
IP phone, and the phone is an older model, there is a filter
that connects between pairs 1-2 and 3-6 in the phone.
Depending on the characteristics of the filter, your tester
may report a fault for pairs 1-2 and 3-6.
