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.
