Diagnostic Capabilities
To provide modem diagnostics, there are three LEDs on the modem
itself. When the unit is first powered up it goes through its own self test
and the status is reflected in the visual status of the LEDs.
Customer Problem Isolation
When application-visible problems are discovered in the field, you
must isolate the source of the problem. Is it the network, wireless
modem, or the host product that is not working as expected? Often it
can be a user’s misunderstanding of how to use the product.
Regardless, remote troubleshooting is essential to reducing the number
of returned products and lowering service costs, particularly if the host
must be disassembled for removal of the modem.
Wavenet recommends that your product application (both at the
terminal and host ends) incorporate sufficient problem diagnostic
software to determine the cause of the problem remotely. Often, the
best approach is to incorporate progressively deeper loop back tests to
determine the point at which the communication link fails.
As stated elsewhere, you need to make this remote diagnostic
functionality be part of your standard software load.
End User Support
You have two choices in dealing with an integrated modem that needs
to be swapped out and returned for service:

Decommission the modem and re-use the LLI

Replace the modem
If you decommission the modem Id (the LLI) from the defective unit
and transfer it to a replacement unit, the user and the network operator
are unaffected. This can only be done by an authorized Wavenet
service centre with the appropriate permissions and authority. If you
simply swap the defective unit with a replacement, the user must notify
the network operator.
Investigate and Obtain Regulatory Approval
Most countries where the final product will be sold currently require
approval from the local government regulatory body. It is your
responsibility to investigate and obtain the proper regulatory approval
and certification for each country in which the product is sold.
Regulatory issues are discussed in more detail in “Regulatory
Requirements” on page 23. In addition, see “Regulatory Compliance”
on page 69.
