Performance Testing of Permanent Links and Channels
There are 3 distinct areas of cable testing; Certification, Qualification and Verification.
Certification is the most rigorous of all cable testing and uses the “Pass/Fail” criteria in
one of the AS/NZS 3080, ISO/IEC 11801 or TIA/EIA 568 standards. The remainder of
this document deals with Certification Testing and it is a requirement for an ADC
KRONE Warranty.
Qualification testing allows technicians to troubleshoot and qualify network cabling for
suitability to a particular technology eg 100BASE-T, GBE, VoIP.
Verification testing determines basic continuity functions eg wiremap, short circuits.
1. Permanent Links And Channels

The fundamental building blocks for a telecommunications system are the permanent
links (PL) and channels (Ch). The field testers needed for PL testing must nullify the
effects of the test leads resulting in plug connector ends that are less than 50 mm
long. The plug connector ends are also required to meet performance criteria that are
electrically “centred”. This means that, as tester manufacturers produce these
“centred” plugs, new plugs will have to be bought for use with the hand-held testers to
obtain accurate PL test results. This requirement only applies to PL testing. Channel
testing still uses the Vendor’s patch cords, which are to be left in place after testing.
The configuration of the Permanent Link and Channel is shown below.

2. Passive Testing With Hand-Held Field Testers
There are currently three levels of hand-held field tester:
Level 2e – for testing up to Class D
Level 3 – for testing up to Class E
Level 4 – for testing up to Class F and the draft 10GBE benchmark
Level 2e Testers
This accuracy level was introduced to achieve the requirements for Class D. It
included those parameters necessary to allow data transmission on four pairs
simultaneously, as in Gigabit Ethernet. These parameters included FEXT, RL and
the calculations for ELFEXT and all POWERSUM parameters. Most level 2e testers
now only have limited support from their manufacturers.
Level 2e testers are no longer accepted by ADC KRONE for full Class D
performance testing.
ADC KRONE strongly recommends that your Level 2e tester be upgraded to a Level
3 tester to test for Class D performance using Cat 5 components.

Level 3 Testers
This accuracy level is associated with the requirements of Class E testing. Software
upgrades are the mechanism used to keep the tester up to date with accuracy and
performance requirements. These testers are complicated instruments and each
manufacturer uses different complex mathematical algorithms in their software to
achieve the necessary accuracy and performance measurements.
The following Level 3 testers are accepted by ADC KRONE for testing Class E
performance, using Cat 6 components:
1. OmniScanner 1 & 2
2. Agilent WireScope WS350 & FrameScope FS350
3. FLUKE DSP 4000/4100/4300. DTX-1200/1800 Level 4 testers also acceptable.
LANTEK testers are not accepted for an ADC KRONE Warranty
Level 4 Testers
This accuracy level is a requirement of Augmented Cat 6, Class E
A
and Class F
testing. These testers can be used on any of the lower Class installations and still
perform at the high Level 4 accuracy.
The following Level 4 testers are accepted by ADC KRONE for testing of Class
E and Class E
A
(Augmented Cat 6) performance for 10Gigabit Ethernet.
1. Fluke DTX-1200 up to 350 MHz - OK for Class E (250 MHz)
2. Fluke DTX-1800 up to 900 MHz - OK for Class E
A
(500 MHz) and 10GBE

4. Class E Warranty Testing Using Cat 6 Components
After testers have been in the field for some time, handling and maintenance issues
can arise from extended use. The Level 3 & 4 testers need to be discussed

individually as each one has unique features.
OmniScanner 1 & 2
The OmniScanner 1 & 2 have the same base unit with one main difference: the
OmniScanner 2 has an external memory card for storing and forwarding test results:
a very handy feature to keep the tester working on-site; the OmniScanner 1 does not.
The ability to test Class E Permanent Links between the two units is the same,
provided they have the latest software version loaded. The testing of Class E
permanent links and channels necessitates using the correct adaptor head listed at
the back of this document.
The PL test heads for the OmniScanner now the Universal Permanent Link Adaptor
head & lead, and the same Personality Module as used with the Fluke DSP 4000
series. This means the unit has a 50 mm lead (ie the Personality Module) thereby
complying with the international requirements for test equipment.
The PL test head for the ADC KRONE FMK and KM8 RJ45 solution must be the
Universal Permanent Link Adaptor + PM06 personality module.
Agilent WireScope WS350 and FrameScope 350
The WS350 and the new FrameScope 350 work well and many installers like their
ease of use, consistent readings and high accuracy. They have the facility for a
removable memory card, but if the Compact Flash card is inserted while the unit is
turned off, the unit may lock up during the next boot sequence. Both units support
both Class E Channel and Permanent Link testing as well as other performance
analysis capability. As with all manufacturers’ tester units, they should be checked for
cable wear at the adaptor interface plugs, which may cause results on RL to vary. A
poor result on RL should be investigated by using a different set of adaptor heads or
a newer tester.
The PL test heads contain a chip that allows the unit to zero out the effects of the test
leads there by making it an effective “50 mm lead”.
Use the generic PL test head and leads for testing the ADC KRONE FMK and KM8
RJ45 sockets.
To test HighBand8 installations, use a N2604A-055A HighBand8 on the jumpered

fields one end, and the generic RJ45 PL test head at the TO.
To test installations using Highband 25 modules, obtain the appropriate patch cords
and test the installation as a Channel

Fluke DSP 4000, 4100, 4300 and DTX-1200, 1800
The difference between the 4000, 4100 and 4300 models is primarily the facility for
external memory. All units give good results for testing Class E Permanent Links and
Channels. ADC KRONE recommends these testers undergo a regular (monthly) P-
CAL calibration. The DTX-1800 is a Level 4 tester that tests out to 900 MHz and will
meet Class E
A
(500 MHz) “10GBE benchmark” performance requirements. DTX-1200
is a Level 4 tester that tests out to 350 MHz and tests for Class E (250 MHz)
performance requirements (not Class E
A
).
Class E and 10GBE Permanent Link heads must have the right Personality Module
fitted. The standard personality module PM06 comes shipped with the DSP4100,
4300 and DTX.
The PM06 module replaces the PM25 and PM01.
Sometimes on the DTX the seating of the PL heads onto the tester is not correct
resulting in incorrectly high readings and high dc resistance readings. Simply re-seat
the PL head onto the tester and re-test.
The PL test head for the ADC KRONE KM8 RJ45 socket is the generic PL test head
LIA101 + PM06.
To test a PL on HighBand8 jumpered installations, use the LIA 101 + PM06 test lead
on the Remote at the TO, and use LIA 101 + PM14A (the HB8 personality module) at
the cross-connect field.
Fluke Test Adaptors DSP-LIA042 and DSP-LIA042A, when used at the Highband 8
IDC module end of a permanent link, are supported by Fluke Networks and by ADC

KRONE Australia as acceptable adaptors for testing of permanent links to Class D
performance. But with the release of the PM14A, they are now NOT acceptable for
testing Class E permanent links.
ADC KRONE Cat 6 patch cords must be used at both ends of a horizontal run to
make up a channel that meets the Cat 6 channel performance test requirements.
To test permanent link installations using HighBand 25 modules, use the new PM15A
(the HB25 personality module).
DSP4300 & DTX memory cards can be MMC (Multi Media Card) 16 MB holding 300
full test records, or MMC 32 MB holding 600 full test records. Do not use SDMMC
cards as they are too thick to fit into the slot.
