6.10 VDSL Alarm Profile Setup
Alarm profiles define VDSL port alarm thresholds. The device sends an alarm trap and
generates a syslog entry when the thresholds of the alarm profile are exceeded.
Click
Basic Settings and VDSL Alarm Profile Setup in the navigation panel to display the
screen as shown.
Compatible Mode Specify the starting band of the frequency range used by VDSL services. The end
frequency band varies depending on the VDSL2 profile (frequency plan) (8a, 8b,
8c, 8d, 12a, 12b, 17a, or 30a) applied to the switch.
This can avoid interference with other services (such as ISDN, ADSL or ADSL2
provided by other device) on the same bundle of lines.
ISDN in Europe uses a frequency range of up to 80 kHz, while ISDN in Japan uses
a frequency range of up to 640 kHz. ADSL utilizes the 1.1 MHz band. Both ADSL2
and ADSL 2+ utilize the 2.2 MHz band.
Select
None to turn on any tone (over 25 kHz). The VDSL services then use the
frequency bands above 138 kHz.
Select
640kHz to have the VDSL services use the frequency bands above 640
kHz.
Select
1100kHz to turn off all tones below 1.1 MHz. The VDSL services then use
the frequency bands above 1.1 MHz.
Select
2200kHz to disable all tones below 2.2 MHz. The VDSL services then use
the frequency bands above 2.2 MHz.
Ham Band Plan To avoid performance degradation due to RFI (Radio Frequency Interference),
you can set your switch not to transmit signals in the pre-defined HAM (Handheld
Amateur Radio) radio band(s).
Optional Band Specify whether the switch is to use the optional band for the upstream traffic.
For POTS, the optional bands range from 25 to 138 K.
For ISDN, the optional bands range from 138 - 276 K.
The optional bands are not supported in a VDSL1 device.
Line Type This displays the VDSL line type ( fastOrInterleaved ), that means either fast or
interleaved channel exists, but only one works at a time.
Add Click Add to save the new profile to the switch. It then displays in the summary
table at the bottom of the screen.
Cancel Click Cancel to reset the fields to your previous configuration.
Clear Click Clear to clear the fields to the factory defaults.
Name This field displays the descriptive name for this profile.
Payload Rate This field displays the configured maximum upstream and downstream payload
rates in megabits per second.
SNR Margin This field displays the configured upstream and downstream signal to noise ration
in decibels.
Applied Ports You can apply a profile to a VDSL port in the Port Setup screen.
This field displays the VDSL port number(s) to which this profile is applied.
Delete Check the rule(s) that you want to remove in the Delete column and then click the
Delete button.
Cancel Click Cancel to clear the selected checkboxes in the Delete column.
