Copper testing with KECT3 (optional)
The KECT3 interface for copper testing is a simple and intuitive solution for troubleshooting and
Copperprequalification.
Operating
The commercially available multiple xDSL systems (digital subscriber line system) have the task to offer fast
data transfer for high-speed Internet access, for remote LAN access and interactive media applications, etc.
The "x" in the name of xDSL signals the different types of DSL technologies, which use conventional copper
cables for fast data transfer. xDSL modems use higher frequencies, and can therefore achieve a higher data
transfer speed, even though they use the same wire pairs as for the analogue telephony (POTS) and
ISDN.The main advantage of xDSL is the omission of the installation cost of new cable.The approved
maximum line length and the maximum sustained data transfer rate depends on the characteristics of the
cable. Before installing a xDSL modem should be checked whether the properties and quality of the selected
pair of wires correspond to the demands of the chosen system.

Connections and test leads
Jack LINE1 (L1)
This connector is the main connector.
Jack LINE2 (L2)
This connector is used for connecting the second pair of wires, e.g. for NEXT measurements, input only.
Test leads
For connection to the measured wire pair two two-wire shielded test leads are used.
Both have on the device side a three-pin TF-plug with 4 mm in diameter and line sided tricolor banana
plugs with 4 mm diameter with compression sleeves. The color coding of the banana plugs are:
n
Wire A
red
n
Wire B
green
n
Ground GND
black
The connection of the leads appended to the selected mode.
When inserting the test leads, please make sure that the
three-pin plug is inserted correctly. The 'B' lead is more
widely spaced than 'A' or GND to prevent the plug from
being inserted incorrectly.
