Release 3.1 Enhancements

Release 3.1 Enhancements
Release 3.1 includes all Release 3.0 functionality plus the toll fraud
and security enhancements listed below.
Star Codes
Star codes are dialable codes for services provided by the CO. The
user has to contract with the CO to get these codes activated.
With this release, users can now add a star (*) code to Allowed and
Disallowed Lists to help prevent toll fraud. The MERLIN LEGEND
system checks if the star codes are allowed. If allowed, the system
then checks the remaining dialed digits against the calling
restrictions.
As a security enhancement, *03 requires a technician to enter a
maintenance password to access test procedures.
Second Dial Tone Timer
Users can program a delay period (Second Dial Tone Timer) during
which no dialing is allowed. This is useful in cases when the CO
sends a second dial tone (such as after a star code); the user may
start dialing before getting the second dial tone, creating a risk of
toll fraud or misrouted calls. If the timer is programmed and dialing
is attempted during the delay, the call is not completed.
Trunk-to-Trunk Transfer
This feature allows or disallows trunk-to-trunk transfer on a per-
station basis. The default setting for all stations is restricted
(disallowed).
Toll Fraud Defaults
This feature changes these default settings:
No station or remote access user with a barrier code may dial
access to any pool.
Disallowed List 7 contains numbers most commonly abused for
toll fraud: 0, 10, 11, 1809, 1700, 1900, 976, 1ppp976 (p=any
number or character), *. Assign this list to extensions as
needed.
VMI ports are maximally restricted. Outward restriction is on and
they are assigned to Disallowed List 7.
FRL settings for VMI ports is 0, for local calls is 2, and for toll
calls is 3.

Release 4.0 Enhancements

Release 4.0 includes all Release 3.1 functionality plus the
enhancements listed below.
System Functionality

enhanced to include the following:
An expanded dial plan supporting up to 200 tip/ring devices.
National ISDN BRI service support for voice and data
connectivity to the CO. Data speeds are 14.4 kbps for analog
