LNB.
This controls the LNB type, DC supply and 10MHz reference to the LNB, and
1:1 LNB control (whether LNB services stay with the failed modem or switch over to
the backup modem on a failure).
Edit-Rx-Carrier-Advanced LNB Menu
The following LNB screens are only available on the L-band modem.
This menu has the following options:
•
LNB type.
This allows selection of the LNB type that is fitted. It also allows the modem
to display and the user to edit the final SHF frequencies instead of the normal L-band
frequencies.
•
PSU.
This allows the DC supply to the LNB from the modem to be turned on or off.
•
Reference.
This controls whether a 10MHz reference signal is supplied to the LNB
from the modem.
•
1-for-1.
This controls whether LNB services (i.e. DC supply and 10MHz reference) stay
with the on-line modem or switch to the standby modem when a 1-for-1 switchover
occurs in a 1-for-1 redundant pair of modems. Note that FSK communications will
always be switched over.
