Running
DSL/IP Tests and
Viewing Results
The 6100-Gfast is designed to make DSL/IP turn-up
easy. The unit will emulate a customer CPE modem to
the point that it can handshake and connect with an
DSLAM and report the upstream and downstream
parameters.
Simply connect to the line, turn on the 6100-Gfast, and
select a test to run. Results obtained include upstream
and downstream throughput and noise margin.
To activate a test:
1. Press the left/right, up/down arrow keys on the
keypad to select the desired test icon.
2. Press
to start the test.
17.1 DSL/IP Connection
Summary
The
Connection Summary
tab allows you to view the
pass/fail status and details of the test results.
When the
Test Interface
for
Auto Test
or
Manual Test
is set to ADSL2+ or VDSL2 bonding mode, there will be
2 columns of results. While the test is running, 2 soft
LEDs will appear above these columns displaying the
2-DSL line condition. The pass/fail status is based on
the 2-DSL line connection state and combined data
rate. Once the test is completed, these 2 soft LEDs
disappear and the pass/fail icon is displayed at the top
of the screen.
Profile
displays the name of the current profile
that results were saved to. You can change the
Profile
within a test once it is stopped.
Pressing the up arrow key opens a list of
profiles from which you can select. Use the on-
screen function buttons to navigate,
Select
a
new profile, or
Cancel
and restore the test
result screen.
Sync Time
is a count-up timer (maximum 99 h)
that starts counting only when the
Line Status
reaches
Show Time
. In the case of bonding,
both lines must reach
Show Time
before the
counter starts.
Line Status
displays the status of the line
under test during negotiation with the DSLAM.
The value changes from
Idle
/
Activate
/
Handshake
/
Training
/
Show Time
for ADSL2+
or VDSL2 mode.
Note: When loading firmware into the Broadcom
chipset, the
Line Status
value displays
Loading
M:SS
, where M:SS is a countdown timer.
Operation Mode
is the xDSL mode of
operation, bonded or non-bonded, as
negotiated between the unit and the DSLAM.
Downstream
/
Upstream
SNR is a value
ranging from 0 through 63.5 for the existing
SNR (signal-to-noise ratio) margin.
Downstream
/
Upstream Max Bitrate
displays
the D/S (downstream) and U/S (upstream)
maximum attainable bit rates that the circuit
can handle as determined by the remote
terminal and CO during the training phase.
Values can be greater than the actual bit rate.
If the
Operation Mode
is bonded, the 2-DSL
line
Max Bitrate
is combined.
Aggregate Data Rate
displays a value of the
gross bit rate if the
Operation Mode
is
G.fast
or
VDSL2-35b
. Otherwise the value is
N/A
.
Downstream/Upstream actual bit rates are
displayed by graphic bars and the current
actual values appear as numbers.
o
Downstream/Upstream bit rate values
are shown in yellow region if they are
greater than Min threshold and less
than OK threshold.
o
Downstream/Upstream bit rate values
are shown in red region if they are less
than Min threshold.
