Release 3.1 Enhancements; Release 4.0 Enhancements - Lucent Technologies MERLIN LEGEND Release 5.0 Pocket Reference

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.
