The terminal will not register with the BGAN Network.
 Is the 'Satellite Selection' configured with the
appropriate setting?
The 'Satellite Selection' allows for specification of
the satellite to use. This can be configured to use a
specific satellite, or to automatically locate the most
appropriate one.
If a specific satellite is selected, ensure that it is
within your field of view. Alternatively, select
'AUTO' if the specific satellite is unknown.
Using the Web interface on the Properties screen, the
terminal shows the "Registration Status" as "Registered", but
the "PS Attach" status as "Not Attached".
Is your BGAN subscription valid?
The most common cause for a failure to PS Attach
is that your BGAN service provider is denying you
service. Contact your BGAN service provider to
ensure the subscription is valid.
The Packet Data Protocol (PDP) context activation attempt
fails because the requested static Internet Protocol (IP)
address is in use or otherwise unavailable.
 Are you requesting the correct static IP address?
Confirm you are using the correct Access Point
Name (APN), username, and password to obtain the
desired IP address. These parameters may vary
based on your geographical location. Check with
your BGAN service provider.
The PDP context activation attempt fails because the
requested static IP address is in use or otherwise unavailable.
 Is the requested IP address permitted in your current
location?
The use of static IP addresses is specific to
geographical regions. Your BGAN service provider
will provide the details. Confirm that you are
requesting the correct static IP address for your
current geographical position.
The PDP context activation attempt fails because the
requested static IP address is in use or otherwise unavailable.
 Was the last context activation made to the requested
IP address properly deactivated?
The BGAN system is designed to allow for short
outages in the connection link between the terminal
and the satellite. For example, when the vehicle
with a BGAN terminal drives behind a building, the
BGAN system will allow the Background PDP
connection to remain broken for one hour. During
that one hour the IP address remains assigned to
that context. (Note, if you remove DC power from
the BGAN terminal without properly deactivating a
context, the BGAN Network will keep the IP
address for that context allocated to that BGAN
terminal for one hour. Moving the Land Portable
power switch to OFF will correctly deactivate the
PDP context before shutting off power to the unit.)
You can power the terminal back on, reactivate the
context, and then properly deactivate it to release
the IP address. Alternatively, wait one hour for
BGAN to release the IP address, or use a different
IP address.
