5.4 The Advanced Screen

Use the Advanced screen to enable or disable ADSL over PTM, Annex M, DSL PhyR, and SRA
(Seamless Rate Adaption) 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.

DESCRIPTION
Select Enable to use ADSL over PTM. Since PTM has less overhead than ATM, some ISPs
use ADSL over PTM for better performance.
You can enable Annex M for the Device to use double upstream mode to increase the
maximum upstream transfer rate.
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.
