Viewing Individual Dsl And Aggregate Bandwidth; Testing Cables; Testing Vdsl - Pace i3822V Installation Manual

3. Check both VDSL 1 and VDSL 2 LEDs on the i3822V.
– Flashing green. Indicates that the links are still being trained; wait until the
lights turn solid green.

Viewing individual DSL and aggregate bandwidth

1. On the Home page, click the Broadband icon.
2. On the Broadband Status page, scroll down the page to view the DSL line 1 and
DSL line 2 detailed information.
3. View the following information and compare it to your operational requirement.
– Rate for both downstream and upstream directions
– Max Rate for the downstream direction
– Noise Margin
– Attenuation
– Output Power
Note: See "Testing cables" on page 53 if any of these readings are outside the
specification.

Testing cables

This section provides information to test the twisted pair and coaxial cables.

Testing VDSL

Using a test toolkit, verify that the line is synchronized with the far-end equipment. The
following measurements will be displayed. Compare them to your operational
requirements.
•
Downstream rate
•
Upstream rate
•
SNR margin for both downstream and upstream directions
•
Maximum attainable rate for the downstream direction
•
Attenuation for the downstream direction
•
Power for the downstream direction
