DTX question (Ethernet wire testing)

[dima-m]

i had dtx done on a 4-wire etherent cable and received a split pair error....; not sure if this definitely means that connector is miswired

also, not sure why is insertion loss so high on pairs 4/5 and 7/8 when it is only a 4-wire setup; dtx is setup for 100base-t...

attached is a pdf of results, if anyone want's to take a look and give their opinion

Never used such equipment, so I can only guess.

The 100base-t setting probably still tests those pairs.  They are sometimes used (eg when people split the one cable into two and run two 100Mbit links over it)

High insertion loss == wire doesn't exist.  Makes sense.

Looks like it (EDIT: or it's a badly/non twisted cable).  Both ends too, so the same person has done both.  Have a look at the order of the coloured wires that have been punched down or crimped.

Without knowing more about the equipment: all of its results may be useless if the pairs are split.  Does it come with a manual?
