Table 3-15. SHDSL Parameters (Cont.)
Parameter Possible Values / Remarks
Wire Interface
2 Wire, 4 Wire
Rate Mode
Fixed, Adaptive
SNR Startup Margin Specifies the downstream current condition target SNR margin for a SHDSL line. The
SNR margin is the difference between the desired SNR and the actual SNR. Target SNR
margin is the desired SNR margin for a unit.
-10..10 (Signal to noise ratio)
Line Probe Enabled Enables/Disables support for Line Probe of the units in a SHDSL line .
Enabled: the system performs Line Probing to find the best possible rate.
Disabled: rate adaptation phase is skipped, to shorten set up time.
Line Mode
STU-C, STU-R
Loop Attenuation
Threshold (dB)
Configures the loop attenuation alarm threshold.
Off, 1…127
Note: Off setting indicates that threshold crossings are not reported
SNR Margin Threshold
(dB)
Configures the SNR margin alarm threshold.
Off, 1…15
Note: Off setting indicates that threshold crossings are not reported
TS Compaction Mode Configures how timeslots will be compacted over the SHDSL line.
No Compaction, No Mapping, With Mapping, Low TSs Mapping
Configuring SHDSL Status Parameters
To configure status parameters:
1. Select a SHDSL Link.
2. Select Configuration > Physical Parameters > SHDSL > Status…
