Rate Adaptive
Rate adaption is the ability of a device to adjust from the configured transmission
rate to the attainable transmission rate automatically depending on the line quality.
The VDSL transmission rate then stays at the new rate or adjusts if line quality
improves or deteriorates.
Select a rate adaptive mode. Select
Manual
to disable transmission rate
adjustment. Select
AdaptAtInit
to enable the switch to adjust to a new lower rate
when the line quality deteriorates until the connection is broken.
Max SNR
Select the maximum SNR (Signal to Noise Ratio) margin allowed on the channel.
Target SNR
Select the target SNR (Signal to Noise Ratio) margin for the channel.
Min SNR
Select the minimum SNR (Signal to Noise Ratio) margin allowed on the channel.
MaxInterleave
Delay
Specify maximum interleave delay for the slow channel. It is recommended that
you configure the same latency delay for both downstream and upstream.
Max Aggregate
Power
Specify the maximum aggregate power level for upstream and downstream
transmission.
Rate Ratio
Select to use the data rate allocated for the fast or slow channel. Valid values are
0
and
100
.
Enter
0
to use slow channel (at the rate you specified in the
Slow Channel
Payload Rate
field) which is best suited for data transmission.
Enter
100
to use fast channel (at the rate you specified in the
Fast Channel
Payload Rate
field) for latency-sensitive applications (such as voice).
Impulse Noise
Protection
Specify the level of impulse noise (burst) protection (in microseconds) for a slow
(or interleaved) channel. Enter a number between 0 and 1275.
FEC Redundancy This field displays the Forward Error Correction (FEC) redundancy overhead for a
fast channel.
This field is neither configurable nor applicable at the time of writing.
Template PSD
Mask
Select a PSD mask for the upstream and downstream traffic.
PBO Control
Set the upstream PBO control. PBO (Power Back Off) allows the switch to provide
better service in a network environment with telephone wiring of varying lengths.
Select
Disable
to disable this feature.
Select
Auto
to set the switch to automatically adjust the power backoff.
Select
Manual
to specify a power backoff level in the
PBO Level
field.
PBO Level
If you select
Manual
in the
PBO Control
field, select a PBO level.
Band Plan
Specify a VDSL band plan to use for the line.
Select
BandPlan998
for ITU-T G.993.1 Bandplan-A and ANSI Plan 998.
Band Plan FX
This field displays the band frequency range (3750 to 12000) between the D2 and
U2 bands.
This field is neither configurable nor applicable at the time of writing.
Applicable
Standard
Your switch automatically selects a standard to use for VDSL services.
Deployment
Scenario
Specify a VDSL deployment scenario.
Select
FTTCab
if the switch is located in a street cabinet.
Select
FTTEx
if the switch is located at the central office (CO).
