Port

DS: Configure the transmit rate of Maximum Downstream. The value of
downstream traffic limitation in Mbps, from the VDSL2 CO Managed
Switch to the CPE. Per port in step of 1 Mbps and 5Mbps.
Default : 101Mbp/s (bit per second)
The range between 1Mbps to 101Mbps

US: Configure the transmit rate of Maximum Upstream. The value of
upstream traffic limitation in Mbps, from the VDSL2 CPE to the CO
Managed Switch. Per port in step of 1 Mbps and 5Mbps.
Default : 101Mbp/s (bit per second)
The range between 1Mbps to 101Mbps
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
The VDSL line type can be configured by selecting maximum Interleave delay
of Downstream or Upstream direction. Basically, there are three types

No limit

Fast mode

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 MaxDelay to be used. Configures
interleave-delay with specifying Downstream or Upstream. The unit is msec.
The range between 0ms to 63ms
Default value: 8ms
In the VDSL2 Managed Switch, all VDSL ports are contained on one profile. To
change the member ports to other profile, the "User Profile Name" has to be
selected first.
Add: Applies Profile to specified ports.
Remove: Disables profile in specified ports.
