Port Adsl Optionmask Command; Port Adsl Pmm Disable Command - ZyXEL Communications MSC1024G Series User Manual

Chapter 31 port Commands
The following example sets the impulse noise protection minimum to 2 DMT symbols for
upstream and 4 DMT symbols for downstream for ADSL port 5 on the line card in slot 7.
ras> port adsl inpmin 7-5 3 4

31.4.11 port adsl optionmask Command

Syntax:
port adsl optionmask <slot-port> <option_mask>
where
<option_mask>
This command masks (turns off) attributes for the specified port(s). It is for advanced
troubleshooting. Use an entry with a "1" instead of "0" before the "x" in order to turn the
attribute back on (remove the option mask).
The following example sets ADSL port 5 on the line card in slot 7 to not use Trellis encoding.
ras> port adsl optionmask 7-5 0x0001

31.4.12 port adsl pmm disable Command

Syntax:
port adsl pmm disable <slot-port>
This command turns off the Power ManageMent (PMM) feature on the specified ADSL2/2+
port(s).
704
: Disables Trellis
= 0x0001
Trellis encoding helps to reduce the noise in ADSL transmissions.
Trellis may reduce throughput but it makes the connection more stable.
0x0002 : Disables Reed-Solomon
Reed-Solomon performs transmission error correction.
: Disables upstream bitswap
0x0004
0x0008 : Disables downstream bit swap
Bit swapping allows the system to respond to noise on a tone by
sending it's data on another tone. The subscriber (ATU-R) equipment
must also support this in order for it to work.
: Disables 1-bit constellation
0x0010
1-bit constellation allows the system to send individual bits over DMT
tones that can only support one bit. This allows the connection to use
as many of the tones as possible.
0x0020 : Disables transmit windowing (ADSL2+ only)
: Disables s=0.5 support option in G.dmt.
0x0040
0.5 support maps two Reed-Solomon codewords into one data frame
(instead of one) to increase the maximum G.dmt transmission rate.
: Disables G.lite rate limit (G.lite only).
0x0080
Disabling the G.lite rate limit allows the G.lite upstream transmission
rate to be greater than 512 Kbps.
