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
• PMD
1
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.
