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 O'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. 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 will be denied access into the
remote access trunks no matter what code is entered.
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. )
