Troubleshooting - DSL Diagnostics Page
The Troubleshooting - DSL Diagnostics page displays data associated with the 3700HGV-B gateway’s VDSL
link.
Note:
Most of the values displayed on this page are calculated once at the start of the
connection. Values that are dynamically updated during the connection are marked with an
asterisk (*).
Analyzing General Information
The General Information pane shows diagnostic information for the current VDSL connection (or connection
attempt). These values are also listed in the last row of the Training History pane.

Reviewing Training History
This pane provides a record of the last 20 connection attempts. The current connection or connection
attempt is displayed in the last row.
Final Rx Gain
Indicates the current
receive gain setting (in
dB).
Dependent on DSL
line length.
Ok

tion

Delay of latency
path
The delay, in millisec-
onds, imposed by the
modem on the interleaved
frames.
Item
Description
*Time
Initially this field will display the time (since power on) in
DAYS HH:MM:SS format, until the gateway can access the
Internet and retrieve the current local time. Subsequently
the time (since power on) is displayed in YY:MM:DD and
HH:MM:SS format.
Line
The line (1 or 2) on which the gateway is searching for a
DSL signal.
Downstream
Rate
The net user data rate (in kbps) for the connection.
Max1
Maximum rate achievable at the time of the initial connec-
tion based on the line quality (specifically, the uncapped
rate).
*Max2
Latest estimate of maximum achievable rate adjusted for
changing line conditions.
Mgn1
Noise margin (in dB) at the start of the connection.
*Mgn2
Latest noise margin adjusted for changing line conditions
since the connection was first established.
Attn
Measured attenuation (dB) of the line.
Pwr
Transmit power (dB).
*CRCs
Total uncorrected errors for this connection.
*FECs
Total corrected errors for this connection.
Upstream
Rate
The net user data rate (in kbps) for the connection.

Reviewing Bitloading
The Bitloading pane shows the bits loaded per tone for the upstream (tones 6 to 31) and downstream
(tones 32 to 255) spectrum. A single hex-digit for each tone shows the numeric value (0 to F) in addition to
the bar-graph depiction.*
Max
Maximum rate achievable at the time of the initial connec-
tion based on the quality of the line (specifically, the
uncapped rate).
Mgn
Noise margin (in dB) at the start of the connection.
Attn
Measured attenuation (dB) of the line.
Pwr
Transmit power (dB).
*CRCs
Total uncorrected errors for this connection.
*FECs
Total corrected errors for this connection.
Mode
The DSL mode used.
Vendor
Vendor ID of the DSLAM (for example, ALCB indicates Alca-
tel DSLAM in G.DMT mode).
Rx Gain
Indicates the current receive gain setting, which will
depend on the length of the DSL line.

Troubleshooting - Event Log Page
The Troubleshooting – Event Log page displays events for the broadband and local network. Log information
is stored in a fixed-size buffer. When the buffer is full, the oldest items are purged from the log. You can
also clear the log contents by clicking the
Clear Log
button.
