LABEL DESCRIPTION
DSL Capabilities
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.
Bitswap Select Enable to allow the Zyxel Device to adapt to line changes when you are using G.dmt.
Bit-swapping is a way of keeping the line more stable by constantly monitoring and redistributing
bits between channels.
