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. If the barrier code length is changed and barrier
codes are not reassigned, users can dial into remote access trunks and enter a
barrier code, but are denied access into the remote access trunks no matter what
code is entered.
!
SECURITY ALERT:
Always use the longest length barrier code allowed on the system.
Barrier codes should consist of a random, non-repetitive, hard-to-guess
sequence of digits.
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 without Barrier Codes” on page –345
to allow or deny use of
system features for each barrier code assigned.
