A_KEY
Settings: 20-digits
Units: None
The A_key is a 26-digit number stored in the mobile station’s permanent security
and identification memory and is not accessible to the user. The number you enter
must match that in the mobile. This field lets you enter the first 20 digits of this
value; the other 6 digits are computed using a special algorithm and are
automatically entered in the
CHECKSUM
field.
The user must obtain a valid
A_Key
from the mobile station’s manufacturer or
from the HLR/AC to test Authentication procedures, otherwise the authentication
process will fail. The Test Set does not write data back to the A_key field during
manual operation.
Authent
Settings: Off or On
Units: None
This turns authentication features on or off for call processing operations.
CHECKSUM
Settings: 6-digit hexidecimal value
Units: None
This field contains the last 6 digits of the A_key. The first 20 digits are entered in
the A_KEY field.
ESN
This field is used to enter the electronic serial number (ESN) of the mobile station.
There are two methods which can be used to enter the
ESN
. The serial number can
be entered as an 8-digit hexadecimal value directly into this field or it can be
captured by the Test Set through a registration order.
To enter the electronic serial number directly, select the ESN field and enter the
information in hexadecimal format.
