Feature Reference
NOTE:
A barrier code cannot begin with
because
a. If a correct barrier code is entered, the caller hears a dial tone and
proceeds to Step 4. If an incorrect barrier code is entered, the caller
hears an alternating high-low tone followed by a dial tone, and can
enter the barrier code again. Up to three attempts are allowed.
b. If the caller enters an incorrect barrier code, he or she hears a retry
tone 15 seconds after the system determines that the code is invalid.
During this step, the caller can enter two asterisks (
entry. This is treated as a failed attempt and the system erases the
code entry and sends a retry tone for another attempt at entering the
barrier code (unless this was the caller's third attempt). If the caller
fails all three attempts at entering the code, he or she hears the
reorder dial tone and is eventually disconnected by the system.
4. The caller may now enter a telephone number, pool number, ARS, or
maintenance code for the desired endpoint.
Class of Restrictions
Barrier codes should be used for all trunks. A maximum of 16 barrier codes is
allowed, each with a different class of restrictions. The class of restrictions allows or
denies the use of system features to individuals or groups of users. Classes of
restrictions are assigned whether or not barrier codes are used for Remote Access or
not. If barrier codes are used, the class of restriction is assigned to each barrier
code. If barrier codes are not used, the class of restriction can be assigned to all
non-tie trunks, or all tie trunks and DID trunks with Remote Access.
The restriction classes are as follows:
Calling Restrictions. Determine whether remote access users can make
local and/or toll calls. The factory setting is Outward-Restricted, meaning
the user can make inside calls only. The restricted user cannot make toll
calls or any outside calls. The setting can be changed to unrestricted
(meaning the user can make inside local, toll, or outside calls) or
toll-restricted (meaning the user can make only inside and local outside
calls). When barrier codes are not used, restrictions are assigned to all
trunks and cannot be assigned to individual tie trunk or non-tie trunks.
When barrier codes are used, restrictions are assigned to individual
barrier codes.
Automatic Route Selection (ARS) Facility Restriction Level. If the
system uses the Automatic Route Selection (ARS) feature, you can
restrict the use of outgoing trunks by remote access users by assigning a
user restriction level from 0 to 6. The factory setting, 0, is the most
restrictive, and 6 is the least restrictive. The value assigned corresponds
inversely to the Facility Restriction Level (FRL) assigned to the ARS route.
(That is, an FRL of 0 is the least restrictive, and one of 6 is the most
