Figure 23-3 VDSL Channel Status
Table 23-5 VDSL Channel Status Counters
FIELD DESCRIPTION
VDSL Channel Parameters: General Status Registers
MODEMSTAT This field displays the modem status.
LINK STAT This field displays the link status. The link is up if this field displays 0xac or 0xae;
otherwise the link is down.
VER_SOFT This is the on-chip firmware version (not patch version).
VER_HARD This is the chip hardware version.
RSTSTAT Reset Status indicates the reason for the most recent system reset.
FAILCNT This field displays VDSL Fail counter information.
DS and US The following parameters apply to both upstream and downstream VDSL.
QAM Constellation shows the modulation method and speed. The constellations are QAM
4, QAM 8, QAM 16, QAM 64, QAM 256 where QAM (Quadrature Amplitude
Modulation) defines how many bits there are per symbol; for example QAM 4 means
2 bits per symbol (2
2
), QAM 8, 3 bits (2
3
) per symbol and so on.
Int Int (Interpolation) defines how fast the symbols go through the line. It is equal to
25.0MHz / baud rate, so for example, Int 8 = 25.0 / 8 Mbaud.
Rate This is the VDSL raw speed.
Fc This is the carrier frequency
SNR The higher the SNR (Signal-to-Noise Ratio) number, the better. SNR (Signal-to-Noise
Ratio is the ratio of the amplitude of the desired signal to the amplitude of noise
signals at a given point in time).
MSE This is the Minimum Square Error. The minimum mean-square error (also known as
MMSE) performance measure is a popular metric for optimal signal processing.
