AT&T MERLIN LEGEND Release 3.1 System Planning Manual page 174

System Features
If foreign exchange (FX) or tie trunks are connected to the system, you can
enter the exchange in the Allowed List to allow people with restricted
telephones to dial numbers to the area code for the FX or tie trunk. As you
design each list, consider which numbers need to be called by specific groups
of restricted users.
Planning Form Instructions
On Form 6e:
1. Write the name of the list in the space next to the list number.
2. Write the allowed area codes, exchanges, and/or star codes in the
spaces provided (a maximum of 10 entries for each list).
3. If star codes are included in the Allowed List, the Second Dial Tone Timer
must also be administered. This timer induces a time delay before the
user may dial additional digits after a star code, and is activated once a
star code has been accepted. The dialing of any digits before this timer
expires is treated as if normal restrictions have been violated and the call
is not completed. The timer may be set from 0 to 5000 ms in increments
of 200 ms. The system default is 0. On Form 1 (page 2), System Planning,
write the desired setting for the Second Dial Tone Timer.
4. Write the extension numbers of the telephones that need access to the
list in the Allow to Ext. Nos. column (see Form 2a).
5. If you planned Remote Access with restrictions and want to permit
Allowed List numbers to be called by remote access users, then do the
following:
NOTE:
Allowed List Class of Restriction assignments apply to all remote access
users and cannot be assigned on an individual basis.
a. On Form 3a (page 3), Incoming Trunks: Remote Access, in the Class
of Restrictions without Barrier Codes section, write the list numbers
under the Allowed List Access heading for either or both tie and
non-tie trunks.
b. On all copies of Form 3a (page 4), Class of Restriction with Barrier
Codes, write the list numbers under the Allowed List Access heading
for each barrier code assigned.
