RANDSSD_1

S:\HP892XX\USRGUIDE\manual\callscrn.fb

RANDSSD_1 is the 24 most significant bits of the random number issued by the

base station in the SSD Update Order. RANDSSD_1 is entered as a 6-digit

hexadecimal value. RANDSSD_1 is user definable.

RANDSSD_2 is the 24 subsequent bits (following RANDSSD_1) of the random

number issued by the base station in the SSD Update Order. RANDSSD_2 is

entered as a 6-digit hexadecimal value. RANDSSD_2 is user definable.

RANDSSD_3 is the 8 least significant bits of the random number issued by the

base station in the SSD Update Order. RANDSSD_3 is entered as a 3-digit

hexadecimal value.

RAND_U is the 24-bit random number issued by the base station in the Unique

Challenge Order. RAND_U is entered as a 6-digit hexadecimal value. RAND__U

is user definable.

The 1 of N field instructs the Test Set how many times to send a system parameter

overhead message. The message contains RAND values, RAND_A and

RAND_B. The RAND values are difficult for phones which do not support

authentication to parse. This field allows for testing of these phones along with the

testing of phones which support authentication by altering the number of times the

system parameter message is sent to the mobile station.
