6.5 The Advanced Screen
Use the Advanced screen to enable or disable PTM over ADSL, Annex M, and DSL PhyR functions.

provide protection against noise on the DSL line. It improves voice, video and data transmission
resilience by utilizing a retransmission buffer.

Table 14 Network Setting > Network Setting > Advanced
LABEL DESCRIPTION
PTM over ADSL Select Enable to use PTM over ADSL. Since PTM has less overhead than ATM, some ISPs
use PTM over ADSL for better performance.
Annex M You can enable Annex M for the Device to use double upstream mode to increase the
maximum upstream transfer rate.
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.
