Security of Your System—Preventing Toll Fraud

As a customer of a new telephone system, you should be aware that there

exists an increasing problem of telephone toll fraud. Telephone toll fraud can
occur in many forms, despite the numerous efforts of telephone companies and
telephone equipment manufacturers to control it. Some individuals use
electronic devices to prevent or falsify records of these calls. Others charge
calls to someone else’s number by illegally using lost or stolen calling cards,
billing innocent parties, clipping on to someone else’s line, and breaking into
someone else’s telephone equipment physically or electronically. In certain
instances, unauthorized individuals make connections to the telephone network
through the use of remote access features.

The Remote Access feature of your system, if you choose to use it, permits off­premises callers to access the system from a remote telephone by using an 800
number or a
acknowledgement signaling the user to key in his or her authorization code,
which is selected and administered by the system manager. After the
authorization code is accepted, the system returns dial tone to the user. If you
do not program specific egress restrictions, the user

The Remote Access feature, as designed, helps the customer, through proper
administration, to minimize the ability of unauthorized persons to gain access to
the network. Most commonly, phone numbers and codes are compromised
when overheard in a public location, through theft of a wallet or purse
containing access information, or through carelessness (writing codes on a
piece of paper and improperly discarding it). Additionally, hackers may use a

computer to dial an access code and then publish the information to other
hackers. Enormous charges can be run up quickly. It is the customer’s
responsibility to take the appropriate steps to properly implement the features,
evaluate and administer the various restriction levels, protect access codes,
and distribute access codes only to individuals who have been fully advised of
the sensitive nature of the access information.

Common carriers are required by law to collect their tariffed charges. While
these charges are fraudulent charges made by persons with criminal intent,
applicable tariffs state that the customer of record is responsible for payment of
all long-distance or other network charges. AT&T cannot be responsible for
such charges and will not make any allowance or give any credit for charges
that result from unauthorized access.

To minimize the risk of unauthorized access to your communications system:

■ Use a nonpublished Remote Access number.

■ Assign authorization codes randomly to users on a need-to-have basis,

keeping a log of ALL authorized users and assigning one code to one
person.

Customer Support Information

xvii

Customer Support Information

Use random sequence authorization codes, which are less likely to be
easily broken.
Deactivate all unassigned codes promptly.
Ensure that Remote Access users are aware of their responsibility to

keep the telephone number and any authorization codes secure.
When possible, restrict the off-network capability of off-premises callers,
via use of Call Restrictions and Disallowed List capabilities.
When possible, block out-of-hours calling.
Frequently monitor system call detail reports for quicker detection of any
unauthorized or abnormal calling patterns.
Limit Remote Call Forward to persons on a need-to-have basis.

Limited Warranty and Limitation of Liability

AT&T warrants to you, the customer, that your MERLIN LEGEND
Communications System will be in good working order on the date AT&T or its
authorized reseller delivers or installs the system, whichever is later (“Warranty
Date”). If you notify AT&T or its authorized reseller within one year of the
Warranty Date that your system is not in good working order, AT&T will without
charge to you repair or replace, at its option, the system components that are
not in good working order. Repair or replacement parts may be new or
refurbished and will be provided on an exchange basis. If AT&T determines
that your system cannot be repaired or replaced, AT&T will remove the system
and, at your option, refund the purchase price of your system, or apply the
purchase price towards the purchase of another AT&T system.

If you purchased your system directly from AT&T, AT&T will perform warranty
repair in accordance with the terms and conditions of the specific type of AT&T
maintenance coverage you selected. If you purchased your system from an
AT&T-authorized reseller, contact your reseller for the details of the

maintenance plan applicable to your system.
This AT&T limited warranty covers damage to the system caused by power

surges, including power surges due to lightning.

The following will not be deemed to impair the good working order of the

system, and AT&T will not be responsible under the limited warranty for

damages resulting from

Voice Mail Systems
Your Voice Mail system permits callers to leave verbal messages for system

users or gain access to the back-up position in an emergency as well as create
and distribute voice messages among system users.

The Voice Mail system, through proper administration, can help you reduce the
risk of unauthorized persons gaining access to the network. However, phone
numbers and authorization codes can be compromised when overheard in a
public location, are lost through theft of a wallet or purse containing access
information, or through carelessness (writing codes on a piece of paper and
improperly discarding them). Additionally, hackers may use a computer to dial
an access code and then publish the information to other hackers. Substantial

charges can accumulate quickly. It is your responsibility to take appropriate
steps to implement the features properly, evaluate and administer the various

restriction levels, protect and carefully distribute access codes.
Under applicable tariffs, you will be responsible for payment of toll charges.

AT&T cannot be responsible for such charges and will not make any allowance
or give any credit resulting from unauthorized access.

To reduce the risk of unauthorized access through your Voice Mail system,

please observe the following procedures:

Employees who have voice mailboxes should be required to use the
passwords to protect their mailboxes.

— Have them use random sequence passwords.
— Impress upon them the importance of keeping their passwords a

secret.

— Encourage them to change their passwords regularly.
The administrator should remove any unneeded voice mailboxes from
the system immediately.

Programming Overview

Introduction to System Programming

The Communications System offers easy-to-use, menu-driven software for

system programming. After your system is installed, you use this software to
reconfigure, update, or modify your system according your changing business
needs, such as modifying or upgrading lines, telephones, and modules
connected to your system.

Planning Forms

Before you begin to program or modify your communications system, you

should familiarize yourself with the system planning forms. Initially, system

planning forms are used to plan your communications system and program your
system during installation. After installation, they remain a source for all
programming information on your communications system database. The
information ranges from the system time and date to specific equipment
configurations and feature programming.

Each planning form is either required or optional:

■ required —

■

optional — forms needed only if the system included the features or
options on the forms.

Before you begin to program or modify your system, review the control unit
diagram on System Planning Form 1 to identify the module types installed in the
system’s control unit. Use this information to program or modify lines and trunks
and assign or reassign lines to telephones. Check the physical control unit to
verify that the modules are placed in the slots identified on the diagram and
correct the diagram on System Form 1 if there are any discrepancies” .

Before you make any changes to your system, be sure to do the following:

■ Keep your planning forms up-to-date by indicating any system

modifications or changes on the appropriate form after the change is
made.

■ Check the Feature Reference for possible feature interactions.

■

Program the system or the system component during the appropriate

idle state. See “Idle States” later in the chapter.

Programming Overview

Types of Programming

There are three types of programming for the communications system:

System Programming

features that affect all or most system users. System programming

requires one the following:

—

an MLX-20L™ telephone connected to one of the first five ports
of the first MLX module in the control unit

— a PC with System Programming and Maintenance (SPM)

software connected to the lower RS-232 port on the processor,
with a built-in modem in the processor. The modem permits

remote programming and maintenance via the public network.

SPM emulates a system programming console on your PC.

NOTE:

If your system has the AT&T Integrated Solution II (IS II) — UNlX®
application, you have a Master Controller equipped with the UNIX
version of SPM. See Chapter 2 for more information.

Extension Programming enables individual telephone users and
system operators (except for QCC operators) to change their telephone
features to meet individual needs. For details on extension programming,
see the appropriate user and operator guides.

Centralized Telephone Programming enables the System manager to
program any feature that can be programmed by individual telephone
users or system operators. Centralized Telephone Programming can be
done on the programming console or on a PC with the SPM software.
For details on Centralized Telephone Programming, see Chapter 4.
