C: Testing
Note:  All AirPrime embedded modules are factory-tested to ensure they 
conform to published product specifications.
Developers of OEM devices integrating Sierra Wireless AirPrime 
embedded modules should include a series of test phases in their 
manufacturing process to make sure that their devices work properly 
with the embedded modules. 
Suggested phases include:
 — Testing of modules when they are received 
from Sierra Wireless
 — Testing of completed devices to obtain 
required certifications before beginning mass production
 — Testing of completed devices with the 
modules embedded
 — Post-production
AT command entry timing 
requirement
Some AT commands require time to process before additional 
commands are entered. For example, the modem will return “OK” 
when it receives 
AT!DAFTMACT
. However, if 
AT!DASBAND
 is received 
too soon after this, the modem will return an error.
When building automated test scripts, ensure that sufficient delays 
are embedded where necessary to avoid these errors.
Acceptance testing
Note:  Acceptance testing is typically performed for each shipment received.
When you receive a shipment from Sierra Wireless, you should make 
sure it is suitable before beginning production.
From a random sampling of units, test that:
Units are operational
Units are loaded with the correct firmware version
