Condition the Test Set for Call Processing

292
The process of testing AMPS authentication (IS-54) through the Call Processing
Subsystem requires the user to synchronize the base station and mobile station.
This synchronization requires that the base station and the mobile station possess
two pieces of shared secret data (SSD) to confirm a valid call. The first piece is
the of the mobile station and the second piece is the mobile station's
ESN
The A-key is a secret 26-digit number stored in the mobile station's semi-
permanent memory. The following sections describe how to:
• Condition the Test Set for Call Processing with Authentication
• Configure the Test Set for authentication
• Turn On The Test Set's Control Channel
• Initialize Call Processing with Authentication
• Page a Mobile Station with Authentication
• Originate a Call with Authentication
• Perform an SSD Update
• Perform a Unique Challenge
Perform the following steps when first entering the Call Processing Subsystem
(that is, the first time the CALL CONTROL screen is selected during a
measurement session).
1 Zero the RF Power Meter.
a Select the RF Gen from the To Screen menu.
b Set the Amplitude field to off (use the ON/OFF key) This prevents cross-
coupling into the power detector while zeroing the power meter.
c Select CALL CNTL from the To Screen menu.
d Select CALL CNFG from the To Screen menu.
e Disconnect any cables from the RF IN/OUT port on the front panel of the Test Set.
