Upstream
Rate
The new user data rate (in kbps) for the connection.
Max
Maximum rate achievable at the time of the initial connection based on the line
quality (specifically, the uncapped rate).
Mgn
Noise margin (in dB) at the start of the connection.
Attn
Measured attenuation (in dB) of the line.
Pwr
Transmit power (in dB).
CRCs
Total uncorrected errors for this connection.
FECs
Total corrected errors for this connection.
Mode
The DSL mode used (G.DMT, T1.413, or G.LITE).
Vendor
Vendor ID of the DSLAM (for example, ALCB indicates Alcatel DSLAM in G.DMT
mode).
State
The internal state of the modem. If there are repeated connection problems,
technical support representatives can use this information to determine at what
point during training the modem failed, or whether the modem is repeatedly failing
at the same point.
Exit Code
Indicates the reason for a lost connection or a terminated training attempt.
Following are examples of the typical values that can be represented:
ERR_LOF_LIMIT - Retrained due to loss of framing.
ERR_LOS_LIMIT - Retrained due to loss of signal.
ERR_HI_BER_LIMIT - Retrained due to excessive CRCs.
RESTART - System deliberately restarted modem (line search, reprovisioning, or 30-
second timeout when waiting for DSL signal.
ERR_STATE_TIMEOUT - Modem timed out during training (for example, the modem
failed to detect pilot signal at the appropriate time).
ERR_ALL_OPTIONS_FAIL - Failed to negotiate a final bitrate with DSLAM.
RETRAIN_HIGHER - Proactive retrain in order to obtain a significantly higher connect
rate.
Echo
A measure of the uncancelled echo
relative
to the background noise on the line.
This is an indication of how much the uncancelled echo is affecting DSL
performance, rather than an absolute measure of the uncancelled echo.
VXCO
Indicates the difference between the gateway’s and the DSLAM port’s crystal
frequency in parts per million (ppm).
Rx Gain
Indicates the current receive gain settings, which will depend on the length of the
DSL line.
INC Tones
Indicates the number of compensation tones on which impulse noise is detected.
