operation

The transmitter is available This is the normal operational state and indicates that the transmitter is

ready to transmit data.

The transmitter is adjusting for

optimal network timing

This condition typically occurs when your DW4020 is first commissioned or

the first time it is used for data traffic. This must occur before the Indoor

Transmit Unit is able to transmit successfully. Typically, this process usually

takes less than a minute.

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 return channel equipment failures in the NOC.

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is out of date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 your software version to ensure that you can enjoy

uninterrupted operation. If you do not use the DW4020 for a long period of

time and miss the updates, you may need to contact Customer Care.

The transmitter is not

receiving network control

messages from the Network

Operations Center

This condition indicates a NOC equipment outage. This may be a transient

condition and the system should recover automatically.

The transmitter is unable to

range because it cannot

communicate with the

Network Operations Center

Ranging is the process that adjusts your satellite transmitter timing

and power. Your satellite transmitter conducts ranging as needed to

ensure that it can communicate successfully with the Network

Operations

Center. This condition can indicate any of the following:

• The NOC is not receiving ranging information from the transmitter. This

may indicate a transmit problem at the NOC. This should get cleared in a

few minutes.

• The transmitter is unable to achieve enough transmit power to send

ranging information to the NOC. Make sure that the power supply is correct.

The power supply should be Part #1031105-0001.

• The transmitter is sending incorrect timing data because the wrong zip

code or latitude/longitude information was entered during installation.

• The outdoor transmitter unit (ODU)--that is, the antenna--is not operating

properly or is not properly connected to the ITU. Please ensure that the

transmit cable is securely fastened to the Transmit Unit.

The transmitter is not available

because ranging has failed

This condition indicates that the transmitter is not operational because

ranging has failed. Ranging is the process that adjusts your satellite

transmitter timing and power. Your 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 your system was operational in the past and you see these

messages repeatedly, you can try to force range by performing the

Connectivity Test.

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.

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.

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 your satellite transmitter timing and power. Your

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.
