Message Displayed Comments
1 The transmitter has been
disabled by the Network
Operations Center
This condition occurs when the transmitter is not enabled. A transmitter may be
disabled for short periods of time by the NOC for service or troubleshooting. It
may also be disabled if the user discontinues the satellite service. If this
condition persists, it can only be corrected by requesting that the unit be
enabled.
2 The transmitter has been
placed in test mode by the
Network Operations Center
This status requires no user action and this test usually completes in 15 minutes
or less. This condition occurs when the NOC places the transmitter into special
transmission modes to measure the performance of the transmitter. When in this
mode, the unit is unable to transmit normal user data to the NOC.
3 The transmitter is locking to
the receive carrier
This condition occurs during initial startup or when the receiver is locking to the
receive signal. It is normal for this condition to persist for up to 10 seconds. If this
condition persists for more than 10 seconds, try disconnecting and reconnecting
the receiver coaxial cable and wait 10 seconds. If the situation still persists, then
the DW6000 may need to be replaced.
5 The transmitter is not locked to
the network timing
No action is necessary if this condition occurs from time to time and quickly
resolves itself. If this issue persists, it is likely due to a NOC-related service
issue. The condition may also be due to DW6000 failure; in rare cases, the unit
may fail and may have to be replaced.
6 The transmitter is not available
because the receiver is not
detecting a signal or is not
locked to the correct network
Check your receive signal. This condition occurs when the DW6000 is not
detecting a good signal. The receiver must be locked to the correct network in
order for the transmitter to operate. If the receiver is not locked (no signal) or is
locked to the wrong network, the transmitter is unable to transmit data. Please
verify that you have a good signal strength by going to the Receive Statistics
page. This could also be caused by inclement weather.
7 The transmitter is not available
because the satellite receiver
is not tuned for normal
operation
This condition occurs when the transmitter is disabled for safety reasons. If this
happens during installation or commissioning, the installer will close the Antenna
Pointing program and resolve the condition.
8 The transmitter is available This is the normal operational state and indicates that the transmitter is ready to
transmit data.
9 The transmitter is adjusting for
optimal network timing
This condition typically occurs when the DW6000 is first commissioned or the
first time it is used for data traffic. This must occur before the DW6000 is able to
transmit successfully. Typically, this process usually takes less than a minute.
10 The transmitter is unable to
communicate with the Network
Operations Center
This condition indicates that the unit has stopped attempting to transmit user
data because there were a number of failures in sending data to the NOC over
the satellite link. This could be the result of weather conditions causing lost
packets or, rarely, return channel equipment failures in the NOC.
11 The transmitter is not available
because the receiver software
is out of date
This condition indicates that the installed software version is not recent enough
to operate on the network. New software will be required from time to time due to
network infrastructure and capability upgrades and in order to maintain network
efficiency and fix any known problems.The system will automatically update the
software version to ensure that you can enjoy uninterrupted operation. If you do
not use the DW6000 for a long period of time and miss the updates, you may
need to contact your service provider.
