Changing Disallowed Lists
Use this procedure to establish Disallowed Lists that contain telephone
numbers than cannot be dialed from specified telephones (including
unrestricted telephones). A Disallowed List takes precedence over an Allowed
List.
Planning Guidelines
Changing Disallowed Lists may affect other features, including Auto Dial,
Automatic Route Selection (ARS), Conference, Forward and Follow Me, personal
lines, Remote Access, and Toll Type. For more information, see the

.
When Disallowed Lists are used in conjunction with Remote Access to restrict
calls made through the system from remote locations, the Disallowed Lists can
be assigned to either a specific barrier code (password) or to specific types of
remote access trunks (for example, all tie/DID trunks).
In Release 3.1 and later systems, star codes may be included in Allowed and
Disallowed Lists. In these systems, dialed star codes are ignored by ARS for
routing calls. Star codes are provided by the central office (CO) to allow the use
of special features (for example, in many areas *70 turns off a call-waiting
feature provided by the central office). In Release 3.0 and earlier systems, the
star code digits were processed as dialed digits by ARS, Allowed Lists,
Disallowed Lists, and calling restrictions. Therefore, the actual called party
number was not properly processed when a star code was entered.
Release 3.1 and later systems permit system managers to include star codes in
Allowed and Disallowed Lists. If a star code is allowed, the digits following the
star code are checked normally by Allowed/Disallowed Lists, calling restrictions,
and ARS.
The MERLIN LEGEND Communications System Release 3.1 and later observes
these Bellcore standards for star codes:
