SIM Data Provisioning Verification (Optional)
At this time the user has the option of verifying the data communications function
from the users system application to the modem prior to connection to the CPE. To
check this path, have the user’s system application send a data stream to the
modem and observe the data stream on the diagnostic terminal for verification of
correct performance.
Match Modem Serial port to CPE
The modem is now ready to be interfaced with the CPE. The serial port settings,
data type, and flow control between the modem and the CPE need to be matched.
Reference
Table 6
for the Redhawk II modem initialization defaults.
