Chapter 6, Authentication Tests
Initializing SSD to Zero
5. Perform a timer-based registration.
HP-IB Syntax
"CDMA:CELL:CONF:TREG:MODE ’ON’" turns timer-based registration on.
"CDMA:AUTH:DATA?" queries the results displayed in the Authentication Data Table.
Manual Operation:
1. Position the cursor at the Timer Reg field.
2. Press the knob to select On.
3. Wait for the first registration to complete (about
20 seconds).
Read the Registration with Authen: message in the
Authentication Data Table. It will indicate
whether the registration passed or failed.
If the test failed, check the passed or failed status
of each the following parameters: AUTHR,
RANDC, COUNT, and AUTH_MODE to see
which parameters did not match expected values.
After the first timer-based registration is
performed, the expected COUNT parameter will
be "Unknown." The Status of COUNT will be
"Failed," until the next registration when an
Expected COUNT parameter is available.
Registrations should occur at about 20 second intervals.
The MSUT and Test Set combine SSD with a random number and the ESN of the phone when computing
AUTHR. This value is transmitted by the MSUT, then compared (along with other Authentication parameters)
with the expected value by the Test Set to determine Pass/Fail status.
