worstcasetgtmgnup
<worstcasetgtmgnup-
val>
This object specifies the upstream worst case
target SNR margin for an SHDSL line. The Only
range supported is -10 to 10. Default value
supported is also deviation from standard RFC.
Type: Modify -- Optional
Valid values: (-10) - 10

WorstCaseUp
Indicates whether a target SNR margin is
enabled or disabled. This is a bit-map of
possible settings.
Type: Modify -- Optional
lineprobe Disable |
Enable
This object enables/disables support for Line
Probe of the units in an SHDSL line. When Line
Probe is enabled, the system performs Line
Probing to find the best possible rate. If Line
probe is disabled, the rate adaptation phase is
skipped to shorten set up time.
Type: Modify -- Optional

Output field
Field Description
IfName
Name of the span configuration profile.
Wire Interface
This object configures the two-wire or optional
four-wire operation for SHDSL Lines.
FourWireBitInterleave are extensions over
standard RFC.
Min Line Rate
This object configures the minimum transmission
rate for the associated SHDSL Line in bits-per-
second (bps). If the 'minlinerate' equals the
'maxlinerate', the line rate is considered 'fixed'. If
the 'minlinerate' is less than the 'maxlinerate', the
line rate is considered 'rate-adaptive'.
Max Line Rate
This object configures the maximum transmission
rate for the associated SHDSL Line in bits-per-
second (bps). If the 'minlinerate' equals the
'maxlinerate', the line rate is considered 'fixed'. If
the 'minlinerate' is less than the 'maxlinerate', the
line rate is considered 'rate-adaptive'.
PSD
This object configures use of
symmetric/asymmetric PSD (PowerSpectral
Density) Mask for the associated SHDSL Line.
Remote Enabled
This object enables/disables support for remote
management of the units in an SHDSL line from
