5.6. DualMODE™ Function for Twisted Pair Cabling
The DualMODE™ function of LanTEK
®
II Cable tester allows measurement in compliance with 2
limits in one single Autotest. Thus, for instance, simultaneous Channel Link and Permanent
Link measurements can be performed.
With DualMODE™ it is possible to perform other important tests. Let us assume you are
installing a Cat-6 system in a country whose government agency uses a national standard
based on ISO. But you are working with cables and connection components manufactured by
a company in the US. The government agency can request a certification according to ISO
Class E from the installer. However, for warranty reasons the US company might insist on TIA
568 Category 6. Therefore, in the past both certifications were required - in compliance with
ISO and TIA - and the increased costs had to be passed on to the customer. In contrast,
DualMODE™ makes it possible to perform both certifications at the same time, in compliance
with ISO Class E Permanent Link and TIA 568B Category 6. The costs are the same as for one
test.
Another example for the use of DualMODE™ is the calculation of margins in relation to higher
bandwidth for future applications. Up to now you had to check the certification documents for
Category 6 Permanent Link and assess whether adequate margins for transmission of
applications at higher bandwidth are available. However, assessment of the complete final
data would also require a certification according to Category 6
A
. Due to higher test costs,
these measures would usually not be performed.
With DualMODE™ you can certify the system in compliance with Category 6, and perform
tests with the limits of Category 6
A
. Due to unmistakable data, your customer would know
exactly what cable lines support higher bandwidths in future applications. This information
would be of great importance when making a decision on whether to assemble cables with
connectors of a higher category, or to pull in cables of a higher category.
5.6.1. Implement DualMODE™
1. Open "Cable Type" on start screen.
2. Use Arrow Keys to navigate to function Twisted Pair DualMODE™ and confirm
with Enter.

3. Use Arrow Keys to navigate to desired cable types. Use soft key to
enable, and soft key Deselect All to disable your selection. An enabled pairing is
indicated by the green box.
4. If you would like another link model, or edit and calculate NVP for the DualMODE™
pairing, press Shift.
