Reset time and

data budget

counters

Click this button to reset the time and data budgets immediately. The count starts over with

the 3G connection’s full configured monthly time and data budgets. This does not affect the

normal monthly budget restart; so if you configured the time and data budget counters to

reset on the second day of the month and you use this button on the first, the time and data

budget counters will still reset on the second.

The Advanced Screen

Use the

Advanced

screen to enable or disable PTM over ADSL, Annex M, and DSL PhyR functions.

The Device supports the PhyR retransmission scheme. PhyR is a retransmission scheme designed to

provide protection against noise on the DSL line. It improves voice, video and data transmission

resilience by utilizing a retransmission buffer.

6.4.1

DSL Bonding

If the DSLAM of your ISP supports DSL bonding, you can connect the two DSL ports on the Device

to two separate telephone jacks and enable the bonding feature in the

Advanced

screen.

DSL signals have distance limitations. VDSL2 (profile 17a) supports greater speed but offer shorter

distances (within 3000 ft). The farther away the subscribers are from the DSLAM, the slower the

speed. VDSL (profile 12a) provides longer distance range (over 3000 ft) but at lower speeds. DSL

bonding allows subscribers to use data streams spread over two DSL lines in order to (almost)

double the speed at longer distances. You may choose to use DSL bonding if the DSLAM supports it

and there are two DSL lines to the DSLAM.

The total available bandwidth for the subscriber then becomes the sum of the bandwidth available

for each of the subscriber’s line connections. The data rate depends on the DSL type, its standard/

profile, and the standard/profile that the DSLAM supports. The table below shows the transmission

data rate for single DSL line and DSL bonding.

Actions when

Specify the actions the Device takes when the time or data limit is exceeded.

Notification

Select this to enable the e-mail notification function. The Device will e-mail you a

notification when there over budget occurs.

Table 12

Comparison Table for Single DSL line and DSL Bonding

For a single VDSL2 line, the profile is 17a, which provides a maximum data rate of 100/60 Mbps

(downstream/upstream). A VDSL2 17a bonding profile can reach 200Mbps/100Mbps. If VDSL

bonding is used, the supported profile is 12a, which provides a maximum data rate of 50/25 Mbps

for each VDSL line. The ideal total data rate for the bonded connection is 100/50 Mbps.

For a single ADSL line, the standard with the highest data rate supported is ADSL2+, which

provides 25/1 Mbps data rate. When ADSL bonding is used, the data rate doubles to 50/2 Mbps.

In addition, DSL bonding supports ADSL bonding fallback. If a VDSL connection cannot be

established, the Device tries to use ADSL. If the VDSL connection is re-established, the Device

automatically switches back to VDSL. You must enable DSL bonding in order to use ADSL fallback.

Select

Enable

to use PTM over ADSL. Since PTM has less overhead than ATM, some ISPs

use PTM over ADSL for better performance.

The following table describes the labels in this screen.

PhyR US

Enable or disable

PhyR US

(upstream) for upstream transmission to the WAN. PhyR US

should be enabled if data being transmitted upstream is sensitive to noise. However,

enabling PhyR US can decrease the US line rate. Enabling or disabling PhyR will require the

CPE to retrain. For PhyR to function, the DSLAM must also support PhyR and have it

enabled.

PhyR DS

Enable or disable

PhyR DS

(downstream) for downstream transmission from the WAN.

PhyR DS should be enabled if data being transmitted downstream is sensitive to noise.

However, enabling PhyR DS can decrease the DS line rate. Enabling or disabling PhyR will

require the CPE to retrain. For PhyR to function, the DSLAM must also support PhyR and

have it enabled.
