Actual Upstream/
Downstream PSD
The actual transmit upstream PSD setting.
Actual Upstream/
Downstream INP
The actual impulse noise protection value for upstream
Max. Upstream Rate Specifies the maximum upstream bit rate to attain for a VDSL port. The valid range for this
parameter is from 32Kb to 14848. Leaving this rate to the default of 10000 (10Mbps)
ensures the higher downstream rates (50 Mbps) for VDSL
Min. Upstream Rate Specifies the minimum upstream bit rate to attain for a VDSL port.
The MINUPSTREAMRATE must be equal or less than the MAXUPSTREAMRATE
Max. Downstream Rate Specifies the maximum downstream bit rate to attain for a VDSL port. The valid range for
this parameter for VDSL is from 32Kb to51200Kb
Min. Downstream Rate Specifies the minimum downstream bit rate to attain for a VDSL port. The valid range for
VDSL is from 32Kb to51200Kb.
The MINDOWNSTREAMRATE must be less than the MAXDOWNSTREAMRATE.
Max. Downstream
Interleave Delay
Specifies the maximum interleave delay in milliseconds used when the VDSL linetype is set
to INTERLEAVE.
Max. Upstream Interleave
Delay
Specifies the maximum interleave delay in milliseconds used when the VDSL linetype is set
to INTERLEAVE.
Target SNR Ratio Margin Specifies the target signal-to-noise ratio (in dB) to achieve on a VDSL port.
The valid range is 0 to 30 for a VDSL interface, with the default 0 for a VDSL interface.
This allows the operator to adjust the signal characteristics to account for such things as
known noise in the binder group, extreme length of a loop, or other issues in the copper
plant
Max. SNR Margin Used to set the maximum signal-to-noise ratio supported by the interface. The value for
this parameter must be greater than the value for Target SNR Margin.
Optionally, this parameter can be set to 'OFF' which eliminates any maximum limit for
SNR.
Min. SNR Margin Sets the minimum signal-to-noise ratio supported by the interface. The value for this
parameter must be less than the value for Target SNR Margin.
Optionally, this parameter can be set to OFF which eliminates any minimum limit for SNR.
Max. Upstream Nominal
PSD
VDSL/ADSL power spectrum density limits are defined by the band plan and determine
this value.
Max. Downstream
Nominal PSD
VDSL/ADSL power spectrum density limits are defined by the band plan and determine
this value.
Max. Receive Power Specifies the maximum received power level in dBm received from the modem before the
interface is alarmed and disabled.
Minimum Upstream INP Sets the minimum impulse noise protection value for upstream.
Minimum Downstream INP Sets the minimum impulse noise protection value for downstream.
Modify Enabled when a value in New Value field has been entered, modifies the attributes
according to the updated values.There is an error message if a value is invalid.
Clear Entry Fields Clear any fields that have been datafilled but not yet Modified
Enable Enabled if the port is in an Administrative State of DOWN, enables the port and so brings
the Administrative State to UP. If possible (for example, the VDSL2 card must be enabled),
the Operational State will change to UP.
