VDSL PHY Status Page
The VDSL PHY Status page shown in Figure 24 represents the current link status of the local modem.
This window is refreshed every five seconds. The status page shows the following values:
SNR of Received Signal:
The SNR of the received
signal is calculated from
the parameters found in
the PMD layer. The SNR
calculation depends on the
QAM constellation of the
received signal.
Mean Square Error: The
mean square error is an
indication of the symbol
error rate. Its calculation
depends on the QAM
constellation and the SNR
of the received signal.
Corrected RS Errors/s: This
field gives the number of
corrected Reed Solomon
errors per second. It is an
indication of the bit error
rate on the line due to
disturbers.
Transmit Power: This field
shows the actual
transmitted power level.
On LT modems with PBO
enabled this value may be
different from the
minimum and maximum
Figure 24 VDSL PHY Status
PSD level adjusted on
the Link Configuration Page (see
Link Configuration section )
Full Constellation Link: Indicates that the full constellation link is working and the modem can transmit
and receive data
Reduced Constellation Link: The modem has synchronized in reduced constellation mode; (QAM4)
only. In this state the VDSL Operating Channel (VOC) is working and the VOC channel can be used
to re-configure the link.
TC Synchronized: Indicates that the transmission convergence layer (TC) is synchronized. VDSL frame
acquisition is working properly and the modem is in SYNC state
Ethernet Encapsulation Sync: Indicates that the Ethernet data path machine has synchronized. In this
state, payload data transmission is working properly.
Remote I/F Synchronized: Indicates that the remote data interface is synchronized.
Signal Detected: Indicates that a signal is detected after the Analog-to-Digital Converter (ADC).
Micro Interruption occurred:
Indicates that a micro interruption (<10ms) has occurred.
AGC Converged: Indicates that the automatic gain control (AGC) has converged.
Timing Converged: Indicates that the timing acquisition function is converged. This indication is only
active in an LT configuration.
