SSD Update
NOTE: An SSD update can be performed on the paging/access channels or on the traffic
channel.
When
SSD Update Execute is selected, an SSD Update Message is sent to the
mobile station, and the
SSD Update annunciator is lit. In response to the SSD
Update Message, the mobile sends back a Base Station Challenge Order.
If the Test Set does not receive the Base Station Challenge Order from the mobile
within 20 seconds, the Test Set will beep and the following message will be
displayed:
No response from mobile to SSD Update request, and the
SSD Update annunciator will be turned off.
If the Test Set receives the Base Station Challenge Order, it sends a Base Station
Challenge Confirmation Order to the mobile station. This order includes the 18-
bit parameter, AUTHBS. After determining whether AUTHBS sent from the Test
Set matches its computed value, the mobile station sends an SSD Update
Confirmation (or Rejection) Order to the Test Set, and a message indicating the
Pass/Fail status is displayed. The
SSD Update annunciator will then be turned
off.
If the SSD_A=0 annunciator was lit before the SSD Update was executed, it will
be turned off.
GPIB Example
“CDMA:AUTH:SSD“
initiates the SSD Update procedure.
Operating Considerations
A successful SSD Update requires the mobile station’s A-Key to be entered in the
A-Key field. The mobile station’s ESN must also be entered in the
MS Database
field. If a valid ESN is not found, the Test Set will beep and display the following
message:
Cannot perform SSD Update until the phone has
registered
