Table 4-9. Network Physical Interface Options (9788)
Line Rate Mode
Possible Settings: AutoRate, Fixed
Default Setting: AutoRate
Specifies the mode to be used for rate selection.
AutoRate – The unit automatically detects the line rate from the network interface.
Fixed – The unit uses the line rate specified by DSL Line Rate.
DSL Line Rate (Kbps)
Possible Settings:
–
If PSD Mask is Symmetric:
200, 264, 328, 392, 456, 520, 584, 648, 712, 776, 784,
840, 904, 968, 1032, 1096, 1160, 1224, 1288, 1352, 1416, 1480, 1544, 1552, 1608,
1672, 1736, 1800, 1864, 1928, 1992, 2056, 2120, 2184, 2248, 2312
–
If PSD Mask is Asymmetric (available in future release) and Region is Annex A:
776, 784, 1544, 1552
–
If PSD Mask is Asymmetric (available in future release) and Region is Annex B:
2056, 2312
Default Setting: [Depends on settings of Line Rate Mode, PSD Mask, and Region]
Determines the rate on the DSL network interface. Valid rates, and the rates presented on
the screen, depend on the values of Region and PSD Mask. If a change to another
configuration option renders the selected DSL Line Rate invalid, the Line Rate Mode is set
to AutoRate.
Display Conditions
– DSL Line Rate does not appear if DSL Line Rate Mode is set to
AutoRate.
200 – 2312 – The DSL line rate is set to the specified rate in Kbps.
Region
Possible Settings: Annex A, Annex B
Default Setting: [Depends on model]
Determines the annex of the G.991.2 recommendation that the unit will conform to. The
value of Region in part determines what DSL Line Rates are available. If a change in the
Region renders the current DSL Line Rate invalid, the Line Rate Mode is set to AutoRate.
Annex A – The unit conforms to Annex A (for North America).
Annex B – The unit conforms to Annex B (for Europe).
PSD Mask
Possible Settings: Symmetric
Default Setting: Symmetric
Read-only. Specifies the Power Spectral Density (PSD) mask the unit will use. The value
of PSD Mask in part determines what DSL Line Rates are available. If a change in the
PSD Mask setting (available in a future release) renders the current DSL Line Rate
invalid, the Line Rate Mode is set to AutoRate.
Asymmetric – (Future use.) The unit uses the asymmetric PSD mask.
Symmetric – The unit uses the symmetric PSD mask.
