Remote Access Barrier Codes - AT&T MERLIN LEGEND Release 3.0 Programming Summary Manual

Remote Access Barrier Codes

Remote Access Barrier Codes
Use this procedure to establish or remove barrier code requirements as well
as to establish or remove the barrier codes themselves.
Barrier codes are security passwords that restrict users from making
unauthorized remote access calls on tie and non-tie lines and trunks. Callers
are allowed three attempts per call to enter the correct remote access barrier
code. If the caller enters an incorrect barrier code or times out during code
entry, the caller hears the retry tone. The caller can erase an entered code by
dialing (two asterisks). Code erasure is counted as one of the three
permitted attempts. After three unsuccessful attempts, the caller hears a
reorder tone and the call is disconnected, If this happens, the SMDR will
contain sixteen 0's in the Account Code field to flag the three failed attempts.
A maximum of 16 barrier codes are allowed for all lines/trunks. Each of the 16
barrier codes may be programmed with its own class of restriction (COR).
The systemwide barrier code length can range from a minimum of 4
characters to a maximum of 11 characters. The default length is 7. If you enter
a length that is less than 4 or greater than 11, the entry is erased and the
previous entry displays on the screen. When the barrier code length is
changed, all barrier codes are erased and must be reassigned.
The time and date of the most recent change made to the systemwide barrier
code length is shown during the system programming procedure as well as
on the Remote Access DISA Information report. The SMDR record for
incoming remote access trunks includes the barrier code IDs established in
this procedure.
Use numbers 0 through 9 and the asterisk (*) to enter the barrier codes. The
codes cannot start with an asterisk and cannot contain two consecutive
asterisks. (The use of two consecutive asterisks is reserved for users to erase
an incorrect barrier code entry.)
See "Remote Access with Barrier Codes: Class of Restriction" to allow or deny
use of system features for each barrier code assigned.
