CC Order
The CC Order field is only visible when authentication is set to ON on the
AUTHENTICATION screen and the Test Set is in the Active state.
This field is used to send an order on the forward overhead control channel to the
mobile station when authentication is turned on. There are two orders available:
• The SSD Update ensures that the data contained in the mobile station and the base
station is identical. At the completion of the SSD Update process the mobile station and
the Test Set will contain identical copies of shared secret data.
• The Unique Challenge order challenges the mobile station’s shared secret data through
a series of algorithm data output comparisons. A successful challenge confirms the
validity of a mobile station’s shared secret data.
The :CCORder command is used to send an order type mobile station control
message to the mobile station. The Access annunciator will light momentarily
while the Test Set is sending the mobile station control message.
The query form of the command (that is, :CCORder?) can be used to determine
the last order sent to the mobile station using the :CCORder command.
