AT&T DEFINITY Remote Port Security Device - Manual (Page 54)

Optionally, a single Key can be used to access multiple Locks. This is done by entering the
[secret_key] information when adding that Key. The same [secret_key] information is then
used when adding that Key to other Locks. The information is then used to generate the test
responce. The secret key chosen by the administrator is the key information to be added
to the RPSD Key. If this option is not used, the RPSD Lock generates the secret key
information randomly.
In any situation where the RPSD Key is already initialized (meaning from another Lock), the
existing
[secret_key] should be specified when adding the user.
In the syntax line above, a is the command and <user_id> is a unique identifier selected by the
administrator. The user ID may be up to ten characters long and is not case sensitive. The
[secret_key] is the pre-defined number of up to 14 hexadecimal digits used for administering
multiple Locks with a single Key.
The RPSD Lock returns secret information and a test response when a user is added. This
information is then used to initialize the RPSD Key, so make sure to note the information. Also,
be careful to maintain the security of the information. The user ID will always be associated
with that particular Key and its secret information and test response. A new RPSD Key must be
initialized after the addition has been made to the Lock in order to gain access. See Chapter 2,
Initializing an RPSD Key for the procedure.
