Update to
Integrated Solution III
System Manager’s Guide
for MERLIN LEGEND®
Communications System
To diminish the risk of toll fraud occurrences, the Transfer to Subscribers
Only? parameter on the System Parameter Administration screen is now
permanently set to yes. This setting restricts transfers to registered subscribers
only. During a transfer from within Automated Attendant, Voice Mail, or Call
Answer services, when a caller enters an extension number, it is validated
against the subscriber database of the AUDIX® Voice Power™ system. If the
extension entered is not in the subscriber database, the caller will hear “That is
not a valid extension,” and the transfer will be denied. This will prevent the caller
from having an opportunity to gain access to the outgoing facilities of the
telephone communications system.
In some cases, it is necessary to allow transfers to extension numbers that do
not have corresponding voice mailboxes. For example, there may be a need to
transfer to a fax or data extension, or there may be a subset of users who do not
need to receive voice mail, but who should be able to receive transferred calls.
In these instances, such extensions can be administered as AUDIX Voice Power
subscribers with restricted mailboxes to ensure transfers to these extensions.
Restricted mailboxes can be set up by allocating minimal mailbox space (for
example, 1 minute). Additionally, the Subscriber Switch Call Coverage option in
AUDIX Voice Power should be set to Yes to avoid tieing up voice channels.
If voice mail is addressed to any of these restricted mailboxes, the limited
mailbox size will prevent most messages from being delivered.
NOTE:
Do not assign special-purpose subscribers (users with a mailbox but no
telephone on the switch) to extension numbers that start with the same
digit(s) as switch trunk access codes (for example, 9).
If you require assistance with the above administration, call the AT&T Support
Center at 1-800-628-2888.

SECURITY
As a customer of new telecommunications equipment, you should be aware of the significant and growing
problem of theft of long distance services by third parties, known commonly as “toll fraud.” It is particularly
important that you understand and take appropriate steps to deal with this crime because under applicable
tariffs, you will be responsible for payment of associated toll charges. AT&T can not be responsible for such
charges and will not make any allowance or give any credit resulting from toll fraud.
Toll fraud can occur despite the preventive efforts of network providers and equipment manufacturers. Toll
fraud is a potential risk for every customer with telecommunications equipment having one or more of the
following features: (1) remote access, (2) automated attendant, (3) voice mail, (4) remote administration
and maintenance, and (5) call forwarding (remote). This is not a product or design defect, but a risk
associated with equipment having one or more of the features described above. If your new
telecommunications equipment possesses any of these features, please consult the relevant portion of your
documentation for further details and specific procedures to reduce the risk of toll fraud or contact your
AT&T dealer for further details.

Introduction 1
Overview of Integrated Solution III
Integrated Solution III (IS-III) is a menu-driven software application that allows you to
administer and maintain your AT&T MERLIN LEGEND™ Communications System
and various applications that your system supports. Your IS-III system consists of a
processor called the Master Controller (II+ or III), a color video monitor, a keyboard,
a tape drive, IS-III Platform Software, and one or more of the following software
application packages:
■
■
■
System Programming & Maintenance Utility (SPM)
System Programming & Maintenance Utility (SPM) allows you to add, move,
and change your telephone features and assignments, and back up and
restore the telephone switch system programming information.
AUDlX® Voice Power™ (optional)
AUDIX Voice Power (AVP) uses voice prompts and announcements to guide
callers in sending and retrieving voice messages through the use of touch-
tone buttons on the callers’ telephones. AUDIX Voice Power can be used as a
personal answering service, a messenger to individuals or groups, an office
receptionist, an information service, and a message drop service.
AT&T FAX Attendant System™ (optional)
FAX Attendant (FA) enhances the capabilities of all fax machines attached to
your company’s MERLIN LEGEND Communications System. FAX Attendant
uses voice prompts and announcements to guide callers in sending and
receiving fax messages through the use of touch-tone buttons on the callers’
telephone. FAX Attendant can be used as a personal fax receiving service, a
fax messenger to individuals or groups, or as an information service allowing
callers to request different fax messages through an interactive voice
prompt/touch-tone interface.
1-1

Introduction
■Integrated Solution Call Accounting System (optional)
With the Call Accounting System (CAS), you can track incoming and outgoing
calls so that you can make informed decisions about your telephone needs.
You can monitor the cost of calls, print reports of incoming and/or outgoing
calls, track calls made on behalf of clients, and identify cases of
telephone abuse. HackerTracker™ software is an optional add-on package that
monitors call activity and provides real-time alarms and alerts for any
abnormal or undesirable call activity, such as toll fraud.
IS-III also provides Integrated Administration, which allows you to perform both
telephone switch system programming and application administration simultaneously
by selecting choices from application-oriented menus and by filling in blanks on
application-oriented forms. Integrated Administration allows information to be entered
only once. All necessary switch system programming is propagated by AUDIX Voice
Power and FAX Attendant to the MERLIN LEGEND Communications System.
NOTE:
Throughout this guide, references to the Master Controller apply to the Master
Controller II+ and III. Any information that differs between the two processors
will be noted.

Introduction
System Manager’s Responsibilities
As the IS-III System Manager, you are responsible for performing the following tasks:
■adding passwords initially and changing them periodically
Maintaining passwords for both logging in and accessing each application
from within IS III helps protect the system from unauthorized access. See
Chapter 4 for the procedures to add and change passwords.
NOTE:
■
■
In addition to adding and changing passwords, the System Manager is
responsible for all aspects of system security. See “Security” later in
this chapter.
backing up the system regularly (daily, weekly, or monthly)
The frequency of your backups depends on how up-to-date you want your call
accounting records, administrative files, voice files, and fax files to be when
you recover from catastrophic failure or any restore. For example, if these
files and records change daily, you should back up the system daily.
Conversely, if these files and records change no more than once a month,
monthly backup is appropriate.
checking and maintaining disk usage space regularly (daily, weekly, or
monthly)
Access the Disk Usage Report and check if there are too many Call
Accounting records, voice messages, and fax messages. You must monitor
these records and messages regularly and maintain disk space for optimal
system performance.
shutting down and rebooting the system properly once a month, when the
system is idle
By using the procedures in Chapter 4 to shut down and reboot the system at
regular intervals, you are able to check the status of the entire system and
possibly prevent major problems.
■
1-3

Introduction
■
■
■
■
■
During a reboot, the system performs the following tasks:
—repairs any minor corruptions automatically, which, if left uncorrected,
could eventually lead to catastrophic failure
—checks the “sanity” of its configuration
—reloads drivers
—re-initializes voice boards and fax boards, ensuring that they are
working properly
creating and changing voice mail group lists for CAS alarm notification
AUDIX Voice Power group lists must be created, configured, and maintained
for CAS alarm notification. Additional information is provided in Chapters 3
and 4 and Appendix C.
monitoring error messages
Each application has error logs; be sure to check the error logs periodically
and follow the suggested instructions when problems or potential problems
occur.
setting the time and date
The time and date for IS III must be synchronized with the time and date for
the MERLIN LEGEND system.
checking printer status
If an optional printer is installed, you are responsible for ensuring that paper is
loaded, and that the printer is turned on and functioning.
reconciling the dial plan
Changes made at the switch cannot be automatically sent to the local
Extension Directory. To keep the databases synchronized when changes are
made at the switch, you are responsible for running the reconciliation program
to download the revised information.
NOTE:
Check your application documentation to determine application-specific
System Manager responsibilities.

Introduction
Security
Your Integrated Solution III system has been carefully designed to be secure. As the
System Manager, it is your responsibility to protect voice and fax mail subscribers
from unauthorized access to their mailboxes. Careful attention to security-related
administrative features, procedures, and maintenance are required to ensure the
integrity of user information. It is your responsibility to read this section and
implement its recommendations as part of your Integrated Solution III environment.
Passwords
A password is one of the most effective ways of securing voice and fax mailboxes
and the Master Controller. In general, all passwords should adhere to the following
guidelines:
■
■
■
■
■
■
■
■
■
Do not use ascending digits (1234) for passwords.
Do not use the same digit repetitively (1111) for passwords.
Do not use the current year (1993) for passwords.
Do not use your extension number as a password (extension 3455 with
password 3455).
Do not use your extension number in reverse order as a password (extension
3455 with password 5543).
Do not use your name or initials as a password.
Passwords should not be posted, shared, or printed in an obvious place.
Passwords should not be coded in programmable function keys or speed-
dialing keys.
Passwords should be periodically changed based on the sensitivity of the
messages or accessible information.
See Chapter 4 for procedures on adding and changing passwords.

Introduction
■
■
■
Subscriber Passwords
Make sure that subscribers understand the importance of password security to their
mailboxes and implement the following guidelines:
Subscribers should change their passwords the first time they log into the
system and periodically thereafter. Consider sending a broadcast message
on the first of each month to remind them.
Subscribers can have passwords of up to nine digits to access the AUDIX
Voice Power and FAX Attendant systems. There is no minimum password
length; however, you should encourage subscribers to make their passwords
at least five digits.
Subscriber passwords are specified in their profiles on the Subscriber
Administration screen. A pound sign (#) in the Password field denies access
to anyone trying to log into the mailbox. The system responds with login
incorrect regardless of what the caller enters. Use this feature whenever it
becomes necessary to restrict mailbox access. Once a subscriber profile is
saved, the password value will not be displayed on the screen. This is for
security purposes. If subscribers forget their passwords, the System Manager
must enter new passwords in their profiles and resave them. The old
passwords are unrecoverable.
Administrative Passwords
Administrative passwords are phone-based and computer-based passwords for the
System Managers and Service Administrators. The following are guidelines for
administrative passwords:
■
■
■
■
■
1-6
Make sure that the passwords set during installation are changed.
Establish and enforce procedures among administrators for changing
passwords. These procedures should include how often passwords are
changed and how notification of new passwords is made.
Because subscribers are required to choose passwords, inevitably some will
forget their passwords. To prevent unauthorized access to a subscriber’s
mailbox, establish a procedure for reissuing passwords in these situations.
Computer-based passwords must be at least six characters long.
You must include both numbers and letters in computer-based passwords.
Passwords are case-sensitive (that is, the system distinguishes between
uppercase and lowercase letters in passwords). Consider using special
characters such as dollar signs, commas, and percent signs.
