a. These are ADSL2 rates.
b. These are VDSL2 rates.
In the saved test report, two additional statistics are included:
– Start Time is the time (time of day) when the DSL modem achieves Showtime. The Start time
is updated if you clear errors.
– Stop Time is the time (time of day) when the report is generated or DSL sync is lost.

Bonded DSL statistics (For Catalogs CSC-TPSVW and CSC-TPSVW-CU only)

For bonded mode, the same results are shown, but the bonded results are separated into different
screens:
– Group - results for both pairs combined
– Pair 1 or Pair 2 - Same results as the non-bonded screen, except the title.

Description
Maximum upstream and downstream connection
rates
The percentage of total bandwidth currently used by
the actual connect rate upstream and downstream.
SNR margin upstream and downstream
The degradation of signal strength in dB upstream
and downstream. It is the differ-ence in Tx power from
the transmitter to receiver.
The elapsed time (duration) since reaching Showtime.
Description
The number of synchronization attempts. it is possible that modems do not syn-
chronize immediately and make multiple attempts before achieving synchroniza-
tion.
Whether the modems trained with the FAST or INTLV (interleaved) path.
The estimated loop length.
V-Configure, V-Full, V-Trigger, V-Running, V-Disabled,
Multiple V-Disabled, V-Unconfigd, V-Unknown
Signal attenuation. Attenuation average of the bins/tones that contain the actual
signal (empty bins are not included).
