Remote Access Barrier Codes
3
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 contains sixteen 0s 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 factory setting 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
