Remote Access Barrier Code Aging/Access Limits
(DEFINITY G3V3 and Later)
For DEFINITY G3V3 and later, including DEFINITY ECS, Remote Access Barrier
Code Aging allows the system administrator to specify both the time interval a
barrier code is valid, and/or the number of times a barrier code can be used to
access the Remote Access feature.
A barrier code will automatically expire if an expiration date or number of access
attempts has exceeded the limits set by the switch administrator. If both a time
interval and access limits are administered for an access code, the barrier code
expires when one of the conditions is satisfied. If an expiration date is assigned, a
warning message will be displayed on the system copyright screen seven days
prior to the expiration date, indicating that the barrier code is due to expire. The
system administer may modify the expiration date to extend the time interval if
needed. Once the administered expiration date is reached or the number of
accesses is exceeded, the barrier code no longer provides access to the Remote
Access feature, and intercept treatment is applied to the call.
Expiration dates and access limits are assigned on a per barrier code basis.
There are 10 possible barrier codes, 4 to 7 digits long. If there are more than 10
users of the Remote Access feature, the codes must be shared.
NOTE:
For upgrades, default expiration dates are automatically assigned to barrier
codes (one day from the current date and one access). It is strongly
recommended that customers modify these parameters. If they do not, when
the barrier codes expire, the remote access feature will no longer function.
When a barrier code is no longer needed it should be removed from the system.
Barrier codes should be safeguarded by the user and stored in a secure place by
the switch administrator. See Chapter 12 for information on administering Barrier
Code Aging.
