•
Transmit data rate. This is the instantaneous transmit data rate, which varies with
MODCOD (MODCOD is the shorthand term used to describe the combination of
modulation and FEC code rate).
•
Transmit MODCOD. This is the current transmit modulation and FEC rate, which
vary with remote Es/No.
•
Remote modem Es/No (energy per symbol to spectral noise density ratio).
Note: Demodulator information is not shown.
ACM operation is described in Section 8.2.
6.2.2.7 Status BUC/LNB Tab
If BUC or LNB services are enabled, then the Status BUC/LNB tab will be available.
Block Up Converter (BUC) / Low Noise Block (LNB) status is continually updated with the
following information:
•
BUC output*: This is the output power in dBm at the waveguide flange, or Off
when the BUC is not transmitting.
•
BUC temperature* This shows the temperature in degrees Centigrade reported by
the BUC.
•
BUC class* This shows the BUC power class in Watts.
•
BUC current: Shows the BUC current level in Amperes if a BUC PSU is installed
•
LNB voltage: Shows the LNB voltage in Volts when an LNB is connected.
•
LNB current: Shows the LNB current in milli-Amperes when an LNB is connected.
*Requires an FSK communications link to exist between the modem and the BUC.
Note: BUC and LNB under and over-current alarms can be controlled via the Edit->Unit-
>Alarms screen.
