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, tech-
nical 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. Follow-
ing 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 perfor-
mance, rather than an absolute measure of the uncancelled echo.
VXCO Indicates the difference between the gateway’s and the DSLAM port’s crystal fre-
quency 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.
