Use the data in this table to initiate a cable diagnostic test and help you understand the TDR display.
Variable | Value | |
---|---|---|
StartTest |
When selected, enables the cable diagnostic test. |
|
TestDone |
Indicates whether the TDR test is complete (true) or not (false). |
|
CableStatus |
Indicates the status of the cable as a summation of the status of the cable conductor pairs.
|
|
Pair1Status |
Indicates the status of the first pair in the cable. Values include:
|
|
Pair1Length |
Indicates the length of the first pair in the cable, in meters, measured by the TDR. |
|
Pair2Status |
Indicates the status of the second pair in the cable. Values include:
|
|
Pair2Length |
Indicates the length of the second pair in the cable, in meters, measured by the TDR. |
|
Pair3Status |
Indicates the status of the third pair in the cable. Values include:
|
|
Pair3Length |

|
Pair4Status |
Indicates the status of the fourth pair in the cable. Values include:
|
|
Pair4Length |
Indicates the length of the third pair in the cable, in meters, measured by the TDR. |
|
CableLength |
Indicates the length of cable, in meters, based on average electrical length of 4 pairs. This measurement can be performed whether or not network traffic is present on the cable. |
|
Pair1Polarity |
Indicates the polarity of the first pair in the cable. This capability is available only when the cable gigabit link is up, regardless of traffic activity. Values include:
|
|
Pair1Swap |
Indicates the status of the pin assignments for the first pair in the cable. Values include:
|
|
Pair1Skew |
Indicates the differential length, in meters, of the first pair in the cable. |
|
Pair2Polarity |
Indicates the polarity of the second pair in the cable. This capability is available only when the cable gigabit link is up, regardless of traffic activity. Values include:
|
|
Pair2Swap |
Indicates the status of the pin assignments for the second pair in the cable. Values include:
|
|
Pair2Skew |

|
|
Pair3Swap |
Indicates the status of the pin assignments for the third pair in the cable. Values include:
|
|
Pair3Skew |
Indicates the differential length, in meters, of the third pair in the cable. |
|
Pair4Polarity |
