Remote Access - AT&T MERLIN LEGEND Release 3.1 System Manager's Manual

Features
Depending upon the equipment you are using, there are many interactions
between data stations and system features. Not all features are available at all
data stations. These features should be disabled at most data stations:
Voice Announce to Busy
Call Waiting
Automatic Callback
Automatic Callback can be used at data stations that include a desktop
videoconferencing and data-sharing system (see Chapter 5, "Optimizing the
System," for more information about this system). Privacy should be turned on at
data stations connected to analog extension jacks, 012 modules, or 016
modules (Release 4.0 and later).
An Auto Answer All button must be programmed at an analog multiline
telephone that is connected by a GPA to a modem. If you use Auto Dial, Last
Number Dial, Saved Number Dial, or Authorization Codes at an analog voice
and modem data station with a GPA set to Auto operation (for automatic
answering of data calls), the user must first lift the handset and then activate the
feature. If a feature turns on the speakerphone at the telephone, the GPA does
not work properly.

Remote Access

The Remote Access feature allows someone outside the system to call in and
use the system as if he or she were on the system. You can and should see that
a barrier code is programmed for each remote access user, who will enter that
code as a password for access to the system. Your AT&T representative will
help you plan these barrier codes as needed and will help you designate an
outside trunk for use by people calling in for remote access to the system.
Remote access requires that you have a certain number of touch-tone receivers
(TTRs) to interpret the digits entered by remote access users, who must use
touch-tone telephones. These TTRs are supplied on the control unit modules.
The number required depends upon the call volume you anticipate. Discuss this
with your AT&T representative.
Calling restrictions can and should be associated with each barrier code, so
that remote access users cannot make unauthorized calls. In a Hybrid/PBX
system, an Automatic Route Selection (ARS) Facility Restriction Level (FRL) can
ensure that remote access users are restricted just like other system users.
NOTE:
In Release 3.1 and later systems, the default FRL assignment for a barrier code
is 0, restricting all outside calls.
