the given media.

If this parameter is set to a fixed value, the system will only try to achieve the specified rate. NOTE: depending on the actual physical link, it may not be possible to achieve the configured fixed bit rate. In that case the system will fall back to some default low-rate link just to provide basic connectivity.

Link

Synopsis: { Down, Scan, Up }

Status parameter - indicates if optimal VDSL link is established. While establishing the optimal link, the device is scanning different VDSL profiles for signal quality to find the profile with the highest throughput.

Link Rate (DS/US)

Synopsis: Any 14 characters

Status parameter - actual VDSL down-stream (Master-to-Slave) and up-stream (Slave-to- Master) bit rate.

SNR Mrgn

Synopsis: Any 9 characters

Status parameter - VDSL signal-to-noise ratio (SNR) margin. The SNR margin is the computed SNR minus the SNR required for 10e-7 bit-error rate (BER). A positive SNR margin of 6 dB or more is needed to ensure reliable service with unknown impairments and temperature variations.
