GENERAL
A. Every cabling link shall be tested in accordance with the field test specifications
defined in ANSI/TIA/EIA95689B.291 “Transmission Performance Specifications for
49pair 100Ω Category 6 Cabling and as defined in the Manufacturer warranty
requirements. Refer to item 1.4 submittals for additional information.
B. Trained technicians who have successfully attended an appropriate training program
and have obtained a certificate as proof thereof shall execute the tests.
C. The test equipment shall comply with the accuracy requirements for level IIIe field
testers as defined in ANSI/TIA/EIA95689B.291. The tester including the appropriate
interface adapter must meet the specified accuracy requirements. The accuracy
requirements for the permanent link test configuration (baseline accuracy plus adapter
contribution) are specified in Table B.2 of Annex B of the TIA Cat 6 Standard. (Table
ARCHITECHNOLOGY
CORNELL – NCP TESTING<IDENTIFICATION & ADMINISTRATION
STANDARD SPECIFICATIONS 27 05 53 – PAGE 12 OF 23

`
B.3 in this TIA document specifies the accuracy requirements for the Channel
configuration.
D. The tester shall be within the calibration period recommended by the vendor in order
to achieve the vendor9specified measurement accuracy.
E. The tester interface adapters must be of high quality and the cable shall not show any
twisting or kinking resulting from coiling and storing of the tester interface adapters.
In order to deliver optimum accuracy, preference is given to a permanent link interface
adapter for the tester that can be calibrated to extend the reference plane of the Return
Loss measurement to the permanent link interface. The contractor shall provide proof
that the interface has been calibrated within the period recommended by the vendor.
To ensure that normal handling on the job does not cause measurable Return Loss
change, the adapter cord cable shall not be of twisted9pair construction.
F. A Pass or Fail result for each parameter is determined by comparing the measured
values with the specified test limits for that parameter. The test result of a parameter
shall be marked with an asterisk (*) when the result is closer to the test limit than the
accuracy of the field tester. The field tester manufacturer must provide documentation
as an aid to interpret results marked with asterisks.
G. All cables and termination hardware shall be 100% tested for defects in installation
and to verify cabling system performance under installed conditions according to the
requirements of ANSI/TIA/EIA95689B.
H. All pairs of each installed cable shall be verified prior to system acceptance. Any
defect in the cabling system installation including but not limited to cable, connectors,
feed through couplers, patch panels, and connector blocks shall be repaired or
replaced in order to ensure 100% useable conductors in all cables installed.
The testing parameters called for in this section shall apply for up to 90 meters of
horizontal cable, a work area equipment cord, an RJ45 outlet and 2 cross connect
connections in the closet.
The test parameters shall include Wire Map, Length, Attenuation and NEXT
Wire Map

f) Any other miswiring
Cable Length
The field tester shall be capable of measuring length of all pairs of a basic link or
channel based on the propagation delay measurement and the average value for NVP.
The physical length of the link shall be calculated using the pair with the shortest
electrical delay. This length figure shall be reported and shall be used for making the
Pass/Fail decision. The Pass/Fail criteria are based on the maximum length allowed
for the Permanent Link configuration (90 meters – 295 feet) plus 10% to allow for the
variation and uncertainty of NVP.
2. The set9up configuration of the NVP shall be based solely on the NVP value
of the cable specified in the approved cable submittal for this project.
Insulation characteristics and twist rate of the wire pair influence NVP in
minor ways and is dependent on the specific manufacturer. Typically, an
‘average’ value for NVP is published for all four wire9pairs in a data cable.
Insertion Loss (Attenuation)
Insertion Loss is a measure of signal loss in the permanent link or channel.
The term “Attenuation” has been used to designate “Insertion Loss.” Insertion
Loss shall be tested from 1 MHz through 250 MHz in maximum step size of 1
MHz. It is preferred to measure insertion loss at the same frequency intervals
as NEXT Loss in order to provide a more accurate calculation of the
Attenuation9to9Crosstalk ratio (ACR) parameter.
Minimum test result documentation (summary report and full plot data, in format and
quantities called for): Identify the worst wire pair (1 of 4 possible). The test results for
the worst wire pair must show the highest attenuation value measured (worst case), the
frequency at which this worst case value occurs, and the test limit value at this
frequency.
NEXT Loss
Pair9to9pair near9end crosstalk loss (abbreviated as NEXT Loss) shall be
tested for each wire pair combination from each end of the link (a total of 12
pair combinations). This parameter is to be measured from 1 through 250
MHz. NEXT Loss measures the crosstalk disturbance on a wire pair at the end
from which the disturbance signal is transmitted (near9end) on the disturbing
pair.
The maximum step size for NEXT Loss measurements shall not exceed the
maximum step size defined in the standard as shown in Table 1, column 2.
3. Minimum test results documentation (summary report and full plot data, in
format and quantities called for): Identify the wire pair combination that
exhibits the worst case NEXT margin and the wire pair combination that
exhibits the worst value of NEXT (worst case).

4. NEXT is to be measured from each end of the link9under9test. These wire pair
combinations must be identified for the tests performed from each end. Each
reported case should include the frequency at which it occurs as well as the
test limit value at this frequency.
Frequency Range (MHz) Maximum Step Sixe (MHz)

TABLE 1
PSNEXT Loss
Power Sum NEXT Loss shall be evaluated and reported for each wire pair from both
ends of the link under9test (a total of eight results). PSNEXT Loss captures the
combined near9end crosstalk effect (statistical) on a wire pair when all other pairs
actively transmit signals. Like NEXT this test parameter must be evaluated from 1
through 250 MHz and the step size may not exceed the maximum step size defined in
the standard as shown in Table 1, column 2.
Minimum test results documentation (summary report and full plot data, in format and
quantities called for): Identify the wire pair that exhibits the worst9case margin and
the wire pair that exhibits the worst value for PSNEXT. These wire pairs must be
identified for the tests performed from each end. Each reported case should include
the frequency at which it occurs as well as the test limit value at this frequency.

ELFEXT Loss, pair to pair
Pair9to9pair FEXT Loss shall be measured for each wire9pair combination from both
ends of the link under9test. FEXT Loss measures the crosstalk disturbance on a wire
pair at the opposite end (far9end) from which the transmitter emits the disturbing
signal on the disturbing pair. FEXT is measured to compute ELFEXT Loss that must
be evaluated and reported in the test results. ELFEXT measures the relative strength
of the far9end crosstalk disturbance relative to the attenuated signal that arrives at the
end of the link. This test yields 24 wire pair combinations. ELFEXT is to be measured
from 1 through 250 MHz and the maximum step size for FEXT Loss measurements
shall not exceed the maximum step size defined in the standard as in Table 1, column
2.
Minimum test results documentation (summary report and full plot data, in format and
quantities called for): Identify the wire pair combination that exhibits the worst9case
margin and the wire pair combination that exhibits the worst value for ELFEXT.
These wire pairs must be identified for the tests performed from each end. Each
reported case should include the frequency at which it occurs as well as the test limit
value at this frequency.
PSELFEXT Loss
Power Sum ELFEXT is a calculated parameter that combines the effect of the FEXT
disturbance from three wire pairs on the fourth one. This test yields eight wire9pair
combinations. Each wire9pair is evaluated from 1 through 250 MHz in frequency
increments that do not exceed the maximum step size defined in the standard as
shown in Table 1, column 2.
Minimum test results documentation (summary report and full plot data, in format and
quantities called for):): Identify the wire pair that exhibits the worst pair combinations
must be identified for the tests performed from each end. Each reported case should
include the frequency at which it occurs as well as the test limit value at this
frequency.
Return Loss
Return Loss (RL) measures the total energy reflected on each wire pair. Return Loss is
to be measured from both ends of the link9under9test for each wire pair. This
parameter is also to be measured form 1 through 250 MHz in frequency increments
that do not exceed the maximum step size defined in the standard as shown in Table 1,
column 2.
Minimum test results documentation (summary report and full plot data, in format and
quantities called for): Identify the wire pair that exhibits the worst9case margin and the
wire pair that exhibits the worst value for Return Loss. These wire pairs must be
identified for the tests performed from each end. Each reported case should include

`
the frequency at which it occurs as well as the test limit value at this frequency
ACR (Attention to crosstalk ratio)
This parameter is not demanded by the standard but may be required in order to obtain
the premise wiring manufacturer’s warranty]. ACR provides an indication of
bandwidth for the two wire9pair network applications. ACR is a computed parameter
that is analogous to ELFEXT and expresses the signal to noise ratio for a two wire9
pair system. This calculation yields 12 combinations – six from each end of the link.
Minimum test results documentation (summary results): Identify the wire pair
combination that exhibits the worst9case margin and the wire pair combination that
exhibits the worst value for ACR. These wire pair combinations must be identified for
the tests performed from each end. Each reported case should include the frequency at
which it occurs as well as the test limit value at this frequency
PSACR
NOTE: This parameter is not required by the standard but may be required in order to
obtain the premise wiring vendor’s warranty. Provide as required for Manufacturer
Warranty.
The Power Sum version of ACR is based on PSNEXT and takes into account the
combined NEXT disturbance of all adjacent wire pairs on each individual pair. This
calculation yields eight combinations –one for each wire pair from both ends of the
link. Minimum test results documentation (summary results): Identify the wire pair
that exhibits the worst9case margin and the wire pair that exhibits the worst value for
PSACR. These wire pairs must be identified for the tests performed from each end.
Each reported case should include the frequency at which it occurs as well as the test
limit value at this frequency.
Propagation Delay
Propagation delay is the time required for the signal to travel from one of the link to
the other. This measurement is to be performed for each of the four wire pairs.
Minimum test results documentation (summary report and full plot data, in format and
quantities called for): Identify the wire pair with the worst9case propagation delay. The
report shall include the propagation delay value measured as well as the test limit
value
Delay Skew (as defined in TIA/EIA95689B.1; Section 11.2.4.11)
This parameter shows the difference in propagation delay between the four wire pairs.
The pair with the shortest propagation delay is the reference pair with a delay skew
value of zero.
