VDSL Port Link Status

Command Attributes

General Status

-Link – Shows the status of the VDSL link.

-Noise Margin – To ensure a stable link, you should add a margin to the theoretical minimum Signal-to-noise ratio (SNR). For details see “VDSL Port Configuration” on page 3-58.

Range: 0-9 dBm. Default: 0 dBm

PMD1 Status

-SNR (dB) –The signal-to-noise ratio of the VDSL line.

-Downstream Rate (Mbps) – The rate at which data is transmitted from the switch to the CPE.

-Upstream Rate (Mbps) – The rate at which data is transmitted from the CPE to the switch.
