17 The satellite transmitter is unable to obtain an
available transmission rate Occurs if the transmitter is unable to range
successfully. Ranging is the automated process of
adjusting the satellite transmitter timing and power.
The satellite transmitter performs ranging as
necessary to ensure that it can communicate
successfully with the gateway. This condition may
be caused by incorrect bit rate mask usage or if the
transmitter in unable to generate enough power to
enable it to transmit, most likely because the
antenna is not accurately pointed. However, it may
also be problem with the transmitter power supply.
Repoint the antenna. If the problem persists, check
the power supply.
18 The transmitter is requesting a transmit
pointing test Occurs during initial installation when the Antenna
Pointing program requests that the transmitter
perform a transmit pointing test. This condition will
continue until the system gateway responds that the
transmitter is either actively performing the test or is
queued to perform the test when gateway test
resources become available. The transmitter may
also report this condition for short periods of time
(less than 5 seconds) when performing periodic
transmit pointing tests during normal operation. No
action is required.
19 The transmitter is queued for a transmit
pointing test May occur during initial installation after the Antenna
Pointing program requests that the transmitter
perform a transmit pointing test and the system
gateway responds that the transmitter is queued for
the next available test time. It may also occur when
the transmitter is performing periodic background
transmit pointing tests at the same time as other
users on the network have requested tests. This is a
normal state after initial installation.
20 The transmitter is performing a transmit
pointing test Occurs when one of the following tests are active:
• During installation, the Antenna Pointing software
requests that the transmitter performs a transmit
pointing test. This condition will continue until the
test is concluded and the Antenna Pointing
software returns to normal operating mode.
• The satellite router performs a periodic
background transmit pointing test to make sure
that the antenna is still pointed correctly. This
periodic test takes less than 5 seconds.
If this condition persists, power-cycle the satellite
router by turning the unit off, waiting 15 seconds,
and turning it back on.
