Cable Fill
displays the type of material the
cable is filled with:
Aircore, Jelly, Pulp, 5 PR
,
or
2 PR
. Setup in the
Cable Book
.
Velocity of Propagation
is the velocity of
propagation for the cable.
Cable Temperature
is the temperature of the
cable under test in either
°F
or
°C
.
DRP Result
The
Data Rate Prediction (DRP)
is a software option
and requires that
WB Attenuation
and
WB PSD Noise
tests are selected to enable the
DRP
test. When
enabled, the page displays the predicted maximum
Downstream
and
Upstream
data rates.
If a calculation is not possible, the calculated bandwidth
data is replaced by a message. It states that the DRP
cannot be completed due to low bandwidth settings in
the Noise PSD and/or Attenuation tests; and that with
the current settings, you can calculate rates up to a
certain
highest possible
Technology
, listed as follows.
If the Noise PSD and/or Attenuation bandwidth
are:
o
< 1.1 MHz then no
Technology
applies.
o
1.1 MHz then ADSL or ADSL2.
o
2.2 MHz, 8 MHz, or 12 MHz then
ADSL, ADSL2, or ADSL2+.
o
17 MHz or 30 MHz then ADSL, ADSL2,
ADSL2+, or VDSL2-17a.
o
35 MHz then all technologies apply.
Recalculate
button allows you to recalculate
data rates after editing the following Test
Parameters:
o
SNR Margin
is the signal-to-noise ratio
margin measured on the line.
o
Bits/Bin
allows you to select the ADSL
bandwidth bit rate.
o
Technology
allows you to select a
frequency band from a list of possible
technologies (subject to the
Software
Options
enabled).
Note: VDSL2-35b requires the VDSL2-35b Data Rate
Prediction software option and CQ Board
Revision J or higher.
o
Reference Point (side)
is either
CO
(default) or
CPE
. Set this value based
on where you connect the tester: for
example, if the tester is connected at
the user side and performs a test
toward the CO, set the
Reference
Point
to
CPE
.
Information
o
Annex
displays the mode:
A
or
B
.
o
Remote Noise Level
ranges from -40
to -110 dBm/Hz (default) and is
configurable in profile *.cqcfg files. The
noise level value is dependent on the
Reference Point
.
To recalculate the DRP:
1. Press the up/down arrow keys to highlight the
desired parameter.
2. Press the left/right arrow keys to
increase/decrease the values.
OR
3. Press on a value to open a list box of
options or the alphanumeric editor screen and
use the navigation keys to scroll through.
4. Press to confirm the value.
5. Press the up button to select the
Recalculate
button.
