D-Link DGE-560T User Manual
The cable which is to be tested consists of four pairs of wire. Each pair is tested, and the result is displayed next to the corresponding pair.
The field “Distance” displays the distance to the fault. The field “Status” displays the states of the cable pairs:
• No.Info —The test has not yet been performed or no info is available.
•
Normal.Cable
—The cable pair is connected correctly.
• Short.Cable —Two or more cable pairs are short-circuited together.
• Open.Cable —A lack of continuity between the pins at each end of the twisted pair cable exists, i.e., the cable pair is not
connected correctly.
• Impedance.Mismatch —The impedance on the cable pair is not correct. Possible reasons for impedance mismatch can
be a not properly connected cable pair, a damaged cable pair, a faulty connector, or a remote system that is down.
•
Test.failed
—The test of the cable pair was not successful.
•
DSP.Data
—DSP Data in the status field is only displayed if a link is up. In this case, the field “Link Status” displays the
speed of the link, e.g., 10Mbps, 100Mbps, or 1000Mbps. (If no link is up, “no link” is displayed.)
• Not.present —Cable pair is not present. This applies for network adapters which can only run with speeds of 10Mbps and
100Mbps and therefore do not use all cable pairs.
