Autotest on Twisted Pair Cable
Autotest performs all of the tests necessary to determine if the cable you are
testing meets the test standards specified for your LAN installation.
The following tests apply to twisted pair cable:
Wire Map
Resistance
Length
Propagation Delay
Delay Skew
Impedance
NEXT (Near-end Crosstalk)
Attenuation
ACR (Attenuation to Crosstalk Ratio)
RL (Return Loss)
PSNEXT (Power Sum NEXT; Model DSP-2000 only)
Some test standards require a NEXT measurement from both ends of the cable. If
you are using another main unit (Model DSP-100 only) or a smart remote as the
remote unit, and you enable remote end testing on the main unit, the Autotest runs
the REMOTE tests supported by the test tool if those tests apply to the selected
test standard.
To Autotest twisted pair cable, refer to Figure 2-2 on the next page and proceed as
follows:
Note
Standard remote units do not support remote end testing.
Note
If the calibration message appears after you start the Autotest, refer
to “Calibrating the Test Tool” in Chapter 6 for complete calibration
instructions.
