NOTE:
You may see both lines sync, drop, and then re-sync again.
This is typical for bonded lines. The modems include a test
probe that syncs both pairs, drops, and then re-syncs in
bonded mode.
Connecting to bonded pairs at the NID/demarc
1. Using the RJ-45 “Y” cable, connect the single end of the “Y” test cable to the jack on
the side of the OneExpert DSL.
2. Connect the blue end of the cable to Modem 1 and the orange end of the cable to
Modem 2 on the NID/demarc.
The line is connected. The modems begin to train on the lines automatically.
Testing the physical layer
You can use the OneExpert DSL to test the physical layer of the xDSL link.
To perform a basic DSL link test
1. Connect to the line and allow the unit to train on the line. If the unit achieves sync, you
have verified the physical layer.
Testing line quality
Once connected to the line, the OneExpert DSL gathers statistics for the line. These statistics
are used to determine the line quality.
1. Connect to the line. See
Connecting to the line on page 90
.
The modem begins the training process automatically. When it reaches show time, the
OneExpert DSL begins gathering statistics.
2. Use the
Connection Details
and
DSL Graph
buttons to view different types of
statistics.
If the unit achieves sync at the desired data rates, noise margins, and attenuation, the
DSL link is good.
3. Use the Tray menu to save the results. See
Saving a report on page 66
.
4. For more information on the results, see
DSL/G.fast Results on page 282
