To provide BOD, the modem communicates with the
satellite and uses uplink bandwidth capacity as required
and allocated to it by the satellite.
High Volume – High Volume Uplink; modem is configured
by NOCC for dedicated use of uplink bandwidth.

Polarization in which the downlink signal from the satellite
is being received. (This is not the same as ODU
polarization.) RHCP
LHCP
Downlink Polarization
Receive signal strength with squinter in azimuth 2 position
during antenna pointing. 0 – 255 SQF at azimuth 2
position
Receive signal strength without the squinter on the feed
horn, measured at the start of the validation phase. Also
known as the
center value .

Troubleshooting installation problems
If you see an error message or other indication of a problem during commissioning or other
phases of modem installation, try the solutions given in
Table 7: Guidelines for installation
troubleshooting on page 35. These are the most common installation problems and solutions.

Corrective action and comments Possible cause Symptom
Repoint the antenna. Antenna may not be pointed
accurately. Low signal strength
Check cable connections and re-terminate if
necessary. A cable may be improperly
terminated.
Make sure ODU polarization is set to LHCP or
RHCP as indicated on the Terminal Pointing Info
screen (Setting for ODU Polarization). LHCP or RHCP polarization
setting may be incorrect. Receive signal strength
is 0 or 1.
