INP 30a
Upstream Rate Limit
Downstream Rate
Limit
1.
The default profile of VDSL port is "30a"
2.
If the SNR margin is configured too big, the transmit rate will slow down, whereas
communications is stable.
3.
If the "MaxDelay" is configured to "No Delay" (Fast mode), error correction will not be
done well, whereas transmit data rate becomes faster.
Interleave
The interleave process is use to correct data error before modulation
digital signal into analog signal. Interleave prevents error by enhanced
correction but may slow down transmit rate because packets are
gathered.
Interleaved mode provides impulse noises protection for any impulse
noise with a duration less than 250 us. By configuring interleave
maximum-delay, it can prevent transmission delay caused of waiting data
gathered.
To skip Interleave process, select "No delay" to operate with Fast mode.
Fast mode guarantees a minimum end to end latency less than 1 ms.
Click on the drop-down list and select the Line Type to be used.
Configures interleave-delay with specifying Downstream or Upstream.
The unit is msec.
The range between 0ms to 63ms
Default value: 8ms
Configure INP with specifying Upstream or Downstream to set minimum
protection values of port provision. Click on the drop-down list and select
the INP (Impulse Noise Protection) to be used.
The range between 1 (or 0.5 for no 30a case) to 16 symbol or No
Protection
Default value: 2 symbol
Configure the transmit rate of Maximum Upstream. The value of
outbound traffic limitation in Mbps, from the VDSL2 CO to the CPE.
Default is No Limit.
The range between 1Mbps to 100Mbps.
Configure the transmit rate of Maximum Downstream. The value of
inbound traffic limitation in Mbps, from the VDSL2 CPE to the CO.
Default is No Limit.
The range between 1Mbps to 100Mbps.
