NOTE:
To maintain system security, Lucent recommends you use
authorization codes.
Authorization codes may be used to:
■ Override a facility restriction level (FRL) assigned to an originating station
or trunk
■ Restrict individual incoming tie trunks and remote-access trunks
■ Track Call Detail Recording calls for cost-allocation purposes
■ Provide additional security control
You can make authorization codes mandatory by setting, on the trunk group
screen, the Auth Code field to
y. Refer to ‘‘Trunk Group’’ on page 967 for more
information.
More information
When you dial an authorization code, the FRL assigned to the extension number,
attendant console, incoming trunk group, or remote access trunk group being used
for the call is replaced by the FRL assigned to the authorization code. The new
FRL functions the same as the one it replaces; however, the new FRL may
represent greater or lesser calling privileges than the FRL that it replaces. Access
to any given facility depends on the restrictions associated with the authorization
code FRL.
Example
A supervisor is at a desk of an employee and wants to make a call that is not
normally allowed by the FRL assigned to that employee’s extension. The
supervisor, however, can still make the call by dialing an authorization code that is
assigned an FRL that is not restricted from making that type of call.
For security reasons, authorization codes range from 4 to 13 digits. The number of
digits in the codes must be a fixed length for a particular DEFINITY ECS.
NOTE:
Once established, the number of digits (4 to 13) in the authorization
code remains fixed unless all codes are removed and re-entered. All
authorization codes used in the system must be the same length.
Incoming trunk groups within a system may be administered to always require an
authorization code. The system applies recall dial tone to a call when the user
must dial an authorization code. If the user dials a correct authorization code
within 10 seconds (interdigit timeout), the call completes as dialed. If the user
