Chapter 6 Basic Setting
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 |
| 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.
