14 The transmitter is not available
because ranging has failed This condition indicates the transmitter is not operational
because ranging has failed. Ranging is the process that
adjusts the satellite transmitter timing and power. The satellite
transmitter conducts ranging as needed to ensure that it can
communicate successfully with the Network Operations
Center. The ranging failure may happen due to the antenna
becoming misaligned or if repeated attempts to range do not
succeed. This condition may also be caused due to adverse
weather conditions. In rare cases, this may also indicate NOC
issues but should clear within a few minutes. If the system
was operational in the past and you see these messages
repeatedly, you can try to force range by performing the
Connectivity Test.
15 The transmitter is waiting for a
ranging request to be
processed by the Network
Operations Center This condition occurs if the system is busy adjusting power
and timing for other users. This process may take up to a
minute or more.
16 The transmitter is waiting for a
transmit request to be
processed by the Network
Operations Center This condition occurs when the system is unable to provide
transmit bandwidth. This occurs when many users sign-on
simultaneously. It should clear in a few minutes automatically.
17 The satellite transmitter is
unable to obtain an available
transmission rate This condition occurs if the transmitter cannot successfully
range. Ranging is the process that adjusts the satellite
transmitter timing and power. The satellite transmitter
conducts ranging as needed to ensure that it can
communicate successfully with the Network Operation
Center. A possible cause is that the transmitter could not
achieve enough power to transmit. This is likely caused
because the antenna is not accurately pointed. However, it
may also be a transmitter power problem. Check the power
supply and make sure that it is Part # 1031105-0001.
18 The transmitter is requesting a
transmit pointing test This condition can occur during installation when the Antenna
Pointing program requests that the transmitter perform a
transmit pointing test. This condition persists until the NOC
responds that the transmitter is either actively performing the
pointing test or is queued to perform the test when test
resources become available in the NOC. This is a normal
condition for initial installation. The transmitter may also
periodically go into this condition for short periods of time
(less than 5 seconds) to perform periodic transmit pointing
tests. These periodic tests are performed to ensure that the
antenna is pointed accurately.
19 The transmitter is queued for a
transmit pointing test This condition can occur during installation when the Antenna
Pointing software requests a transmit pointing test and the
NOC has responded 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 that other users on the
network have requested tests. This is a normal state after
initial installation.
