Configuring the Power Backoff
You can determine if the transmitted power backoff is used.
³ To configure the use of the power backoff:
1. From the SHDSL Local Port/SHDSL Remote Port menu, select Power backoff
(Main menu > Configuration > SHDSL Configuration > SHDSL Local Port/SHDSL
Remote Port > Power Backoff) (see
Figure 4-21 and Figure 4-22 ) to enable or
disable power backoff:
 Disabled – the transmission power is 13.5 dBm on each 2W line as long
as the SHDSL bitrate is less than 2.048 Mbps and 14.5 dBm on each 2W
line as long as the SHDSL bitrate is greater or equal to 2.048 Mbps
