Table 14 VDSL Profile Setup (continued)

LABEL

DESCRIPTION

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.

 

 

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.
