❼ Reliable: Select ”noise-margin reliable” to let the rate auto-negotiation
optimise for reliability (rather than high data rate).
❼ High-Speed: Select ”noise-margin high-speed” to let the rate auto-
negotiation optimise for high data rate (rather than reliability).
❼ Normal: ”noise-margin normal” is the default setting for the noise-
margin, which gives a tradeoff between reliability and high-speed. Al-
ternatively, the command ”no noise-margin” can be used.
Using the parameter nonstrict after the selected noise-margin mode
will configure the unit to a less strict algorithm during the connection
phase. The resulting current SNR will not necessary match the config-
ured noise-margin mode.
Use ”show noise-margin” to show the SHDSL port’s noise-margin setting.
Default values ”noise-margin normal”
Error messages None defined yet.
10.3.5 Setting SHDSL port G.HS Threshold
Syntax [no] ghs-threshold <low|medium|high>
Context SHDSL Port Configuration context
Usage Set SHDSL port to operate with new G.HS Threshold value. The G.HS
Threshold setting is only needed if the unit are located in a noisy environ-
ment with SHDSL line cables of good quality and where a connection can
not even be established at SHDSL rate 192kbit/s, see
section 10.1.2 . The
setting configures a higher threshold of the G.HS idle parameter in order to
detect idle. The SHDSL line length capability will be affected, since the G.HS
idle threshold and the G.HS signals meet earlier when the G.HS Threshold is
raised.
When enabling G.HS Threshold, possible settings include”low”, ”medium”,
”high” and a custom configured value. Corresponding values to the fixed
value settings are [low-750; medium-1500; high-3000].
The custom configured value could be set in the range [0-32767] in steps of
1.
Use ”no ghs-threshold” to disable the G.HS threshold.
