Use the Advanced screen to enable or disable ADSL over PTM, Annex M, DSL PhyR, and SRA (Seamless
Rate Adaptation) functions. The Zyxel 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. It also lists ITU-T G.993.2
standard VDSL profiles you can comply with.
ITU-T G.993.2 standard defines a wide range of settings for various parameters, some of which are
encompassed in profiles as shown in the next table.
Note: If the settings in the screen are changed, the Zyxel Device will re-establish the DSL
connection(s).
