Transmit LIU Waveshape (Line Build-Out)
This switch selects the optimal transmit waveshape for the line build-out distance on
the coax line. The transmit waveshape can be set for a distance of either 0 to 255
feet or over 255 feet. This feature corrects problems related to cabling (i.e. cross-talk,
electromagnetic interference, etc.). Improperly setting this switch will cause signal
degradation.
By default this feature is set to
> 255 FEET
.
This feature can be controlled by SNMP management software (iView
2
) when the
iMcV-DS3/E3/STS module is installed in a managed chassis.
