Range:
0.1A to 6.0A; step size: 0.01A
Description:
Sets the trip threshold at which a fault is declared when the current drawn
by the Tx ODU is outside the limit. Both a minimum and a maximum
current threshold can be set. These set the current thresholds outside of
which an alarm will be generated.
Table 6-45 BUC DC Current Minimum/Maximum
6.2.10.6 LNB DC Current Alarm
From the second half of 2014 onwards, hardware support has been added to the modem
to monitor the LNB current.
Table 6-46
describes how to set the LNB minimum and
maximum DC current levels outside of which an LNB DC current alarm will be raised if
LNB DC alarm enable
is set.
Range:
0 to 500mA; step size: 1mA
Description:
Sets the trip threshold at which a fault is declared when the current drawn
by the Rx LNB is outside the limit. Both a minimum and a maximum
current threshold can be set. These set the current thresholds outside of
which an alarm will be generated.

The station clock input is a way of providing a common clock to a number of modems in
order to synchronize all satellite traffic to a master clock.
The modem’s terrestrial interface clocking function (both transmit and receive) is slaved to
the station clock input when it is active. The station clock can be provided at any of a
range of frequencies and does not need to be fixed at the precise data rate for the link.
