 Enter the extension number of the person who will monitor violations in the
Referral Destination field(s). For releases before DEFINITY G3V3, this
destination must be a station equipped with a display module or an
attendant console. In DEFINITY G3V3 and later, which includes DEFINITY
ECS, if an announcement extension is administered, the referral
destination does not require a display module. In G3V3 and later, including
DEFINITY ECS) a violation occurs based on the number of invalid attempts
and is not dependent on a forced disconnect.
NOTE:
If an announcement extension is administered, but no announcement
is recorded, the referral call will not be made.
 For Remote Access, enter the number of attempts allowed before a
violation occurs in the Barrier Code Threshold field, and enter the time
interval in hours or minutes for tracking the number of attempts.
 For logins, enter the number of login attempts before a violation occurs in
the Login Threshold field and the time interval in hours or minutes for
tracking the number of attempts. To register as a violation, there must be
three invalid login attempts (resulting in a forced disconnect) within the
assigned time interval.
NOTE:
If you set the Barrier Code Threshold to 1, any unsuccessful first
attempt by authorized users to enter the barrier code will cause a
violation. A suggestion is to set the threshold to allow three attempts
within five minutes to allow for mistakes made by authorized users.
 In the Feature Button Assignment field, enter rsvn-call for the Remote
Access Security Violation Notification button and
lsvn-call for the Login
Security Violation Notification button. The feature activation buttons do not
have to reside on the referral destination station. They can be administered
on any station. However, they must be activated before referral calls are
sent to the referral destination.
NOTE:
For DEFINITY G3V3 and later releases, which includes DEFINITY ECS,
these buttons are called “lsvn-halt,” and “rsvn-halt.” A new button,
“asvn-halt,” lights the associated status lamp for the assigned station.
The buttons operate the opposite way from DEFINITY G1 and G3
pre-V3 buttons; if activated, the calls are not placed.
