The page includes the following configurable data:
■ VDSL2 over Ethernet Interface (Port-1 to Port-8)
Object Description
• Port
Indicate Port number.
• Type
Indicate the Ethernet interface type.
• Link
Indicate the Port link status: Up or Down.
• Admin
User can disable or enable this port control.
Enable –- Make the port to be in operation.
Disable – Make the port to be paused.
• Mode Fast mode guarantees a minimum end to end latency less than 1 ms.
Interleaved mode provides impulse noises protection for any impulse noise with a duration
less than 250 us. Interleaved mode has a maximum end to end latency of 10m sec.
• Rate Limit
Down
The value of inbound traffic limitation in Mbps, from the VDSL2 Switch to the CPE. Per port
in step of 1 Mbps and 5Mbps.
Default : No Limit.
The range between 1Mbps to 100Mbps.
• Rate Limit Up The value of outbound traffic limitation in Mbps, from the CPE to the VDSL2 Switch. Per
port in step of 1 Mbps and 5Mbps.
Default : No Limit.
The range between 1Mbps to 60Mbps.
• SNR Margin Target SNR (Signal Noise Ratio) Margin
When fixed SNR margin is selected, the system will maintain the SNR margin at 9 dB
across all usable loop length.
The line quality is determined by using the SNR (Signal to Noise Ratio) and applies to VDSL
line connections only. SNR is the ratio of the amplitude of the actual signal to the amplitude
of noise signals at a given point in time. The higher the SNR is, the better the line quality.
Please manually adapt SNR margin according to line quality and distance to get better
performance or replace the line with new one.
• Description
Can key in the description for the port.
The maximum data rate for VDSL2 ports depends on the physical link.
