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 preventative 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

MERLIN® Identifier is a MERLIN telephone system adjunct that
lets businesses use Caller ID* service to support business
operations. If your regional telephone company provides Caller ID
service, your business can use the MERLIN Identifier system to
do the following:

■

■

■

Display the telephone number of an incoming call if the
call was made from a local exchange with Caller ID
service within your LATA (Local Area Telephone Access)

Display the caller’s name if the incoming call’s telephone
number matches a telephone number and name in the
MERLIN Identifier database, or it can display the name
and number if both are provided by the telephone
company

Beep to ensure that the caller receives attention if the
incoming call’s telephone number has been designated
as a “priority” call in the MERLIN Identifier database

*

Caller ID is a Custom Local Area Signalling Service (CLASS) offered by
regional telephone companies for selected calling areas or exchanges.
Contact your telephone company to find out the telephone exchanges
providing Caller ID in your LATA calling area.

Introduction

Review information for the last 18 calls on each of four
telephone lines to ensure that callers have received
timely service

If the MERLIN Identifier system is used with a purchased
Windows™-based contact management software application, or
your own custom database management software running on a
personal computer (PC), you can use the MERLIN Identifier
system to do the following as well:

■

■

■

■

■

Set up a business-specific profile (database) of additional
caller information that displays automatically when a
call’s telephone number matches a telephone number
already in the profile

Add notes or memos to the profile as the call progresses
Transfer caller names and telephone numbers between

the MERLIN Identifier database and the PC database
profile

Maintain a call history log of incoming calls, both
answered and unanswered

MERLIN Identifier
Components and Features

The MERLIN Identifier system consists of a Control Unit, individual
Display units, an Administrative Keyboard, and an Administrative
Display unit. Optionally, the MERLIN Identifier system can
connect to a personal computer (PC) for administrative or
database management functions and to a serial printer to output
Caller ID information. Refer to Figure 1 as you read about the
MERLIN Identifier component descriptions that follow.

MERLIN Identifier Components

MERLIN Identifier Control Unit

provides Caller ID functions,
administrative functions, and the MERLIN Identifier database. For
each incoming call, the MERLIN Identifier system sends the
following information to the MERLIN Identifier Displays: the last
two digits of the line number on which the call was received, the
time and date of the call as recorded at the Central Office, and if
the caller’s exchange provides Caller ID service, the caller’s
telephone number as well.

MERLIN Identifier Components and Features

3

Introduction

If the telephone number matches a record in the MERLIN
Identifier database that has a name associated with it, the
MERLIN Identifier system also sends the caller’s name to the
MERLIN Identifier Displays. If the Central Office sends the caller’s
name with the telephone number and there is no matching name
in the database, the name supplied by the Central Office is sent
to the MERLIN Identifier Displays.

MERLIN Identifier Displays

display the information sent to
them from the MERLIN Identifier Control Unit—both Caller ID
information as it is received and MERLIN Identifier database
information that corresponds to the caller’s telephone number. If
the caller’s MERLIN Identifier database record has a “priority
flag,” the MERLIN Identifier Display can be set to beep to call
attention to it. The MERLIN Identifier Display can also be set to
beep at every call, or never to beep at all. Users can scroll
through the information displayed for the last 18 callers on each of
up to four Central Office lines.

See the MERLIN Identifier User’s Quick Reference for more
information on MERLIN Identifier Displays.

MERLIN Identifier Administrative Display and Keyboard

are
used by the system administrator to set up the MERLIN Identifier
system and maintain the MERLIN Identifier database. MERLIN
Identifier command menus, messages, and prompts are
displayed on the Administrative Display. Single character
administrative commands are entered on the Administrative
Keyboard and simultaneously displayed on the Administrative
Display.

Administrative PC

is a customer-provided PC that can be used
in place of the standard Administrative Display and keyboard to
provide additional administrative features such as expanded
menus and prompts, and data transfers between the MERLIN
Identifier database and database software running on the PC.

MERLIN Identifier Components and Features

Introduction

NOTE:

The Administrative PC requires asynchronous communications
software to communicate with the MERLIN Identifier Control Unit.

Serial Printer

provides a printed copy of Caller ID information,

such as line number, caller’s telephone number, caller name from
MERLIN Identifier database, and day and time of call, as it is
received by the the MERLIN Identifier Control Unit. This printed
copy can be used as a source of data for the MERLIN Identifier
database. If desired, you can connect a PC instead of the printer
to capture the Caller ID output for use in your own custom PC
applications.

Supported Telephone Equipment

The MERLIN Identifier system supports all past and present
MERLIN telephone systems and stations.

MERLIN Identifier Database

The MERLIN Identifier Control Unit lets you create and maintain a
database of approximately 2500 caller records consisting of a

10-digit telephone number and a 16-character name. If many of
the caller names are less than 16 characters, even more caller
records can be maintained.

The system administrator is responsible for creating and
maintaining the MERLIN Identifier database. Using either the
Administrative Display and Keyboard, or optionally, an
Administrative PC, the system administrator enters the telephone
numbers and names of callers into the MERLIN Identifier
database as they should appear on the MERLIN Identifier
Displays.

MERLIN Identifier Components and Features

Introduction

Database Integrity

The following features ensure the integrity of the caller information
in the MERLIN Identifier database:

■

■

■

■

Password entry is required before access to
administrative database functions is permitted

Access to administrative functions “times-out” after 120
seconds of keyboard inactivity—password entry is
required before the administrative functions can be
accessed again

Record locking during edit prevents the “half-edited”
database records from displaying at the MERLIN

Identifier Display—the original, unedited record displays
instead

Capacitor power backup retains data for a minimum of
72 hours following power loss

Database Transfers

The system administrator can transfer caller information between
the MERLIN Identifier database and a database management
system running on the Administrative PC. Both database upload
and download transfers are supported using asynchronous
communications software, such as PROCOMM PLUS® or
Windows Terminal*, and either XMODEM or text file transfer
protocols.

*

Although other asynchronous communications software may work, only
PROCOMM PLUS 2.01 and Windows 3.1 Terminal are recommended for
use with MERLIN Identifier.

STEP 6:

Connecting Administrative Components

Installing the MERLIN Identifier System

Connecting a PC
Instead of the Printer

A PC running asynchronous communications software can be
used instead of a serial printer to capture Caller ID information

from the MERLIN Identifier Control Unit. If you are using an
Administrative PC, the same PC can be used if it has a free serial
port or you install a switch box.

The PC can be situated in the same room as the MERLIN
Identifier Control Unit or located in another room. If you want to
locate the PC in another room, you will need to install a jack near
the MERLIN Identifier Control Unit and another jack near the PC,
and run an inside wire between the two jacks before using the
procedure that follows.

To connect a PC to the MERLIN Identifier Control Unit, follow the
steps below:

1.

2.

3.

Unplug the the MERLIN Identifier Control Unit power cord
and switch off the PC.

Connect the RJ45-to-DB9 adapter labeled “Printer Port
Controller Serial Port Only” to the MERLIN Identifier Control
Unit port labeled “Serial Printer.”

Connect one of the following adapters to the PC’s serial port:

■

■

For a 9-pin COM port, connect the RJ45-to-DB9
adapter labeled “Serial Port PC.”

For a 25-pin COM port, connect the RJ45-to-DB25

adapter labeled “Serial Port PC.”

Database

MERLIN Identifier
Database Description

The MERLlN® Identifier database stores records in the following
format:

PAAAAAAAAAAAAAAAANNNNNNNNNN

where:

P

is a Priority flag.

AAAAAAAAAAAAAAAA

is the 1-to-16 character caller

name.

NNNNNNNNNN

is the caller’s 10-digit telephone number.

The MERLIN Identifier database can store approximately 2500
records. Because the MERLIN Identifier database stores caller
records using variable record-length format, more memory is
available to store additional records when caller names are less
than the 16 characters allotted. For example, if 900 records use
13-character names instead of all 16 characters, an additional
100 database records with 16-character names could be stored.

MERLIN Identifier Database Description

33

Administering the MERLIN Identifier Database

Caller Names

All upper-case alphabetic characters and punctuation marks can
be used for caller names. The MERLIN Identifier system stores
database records in alphabetical order by caller name. To
facilitate recognition of names on the MERLIN Identifier Displays,
always record caller names in the same format—such as last
name first. For example, enter SUE WALLACE and BERT
WASHINGTON into the database as

WALLACE, SUE

and

WASHINGTON, BERT,

or

SUE WALLACE

and

BERT

WASHINGTON,

but not

WALLACE, SUE

and

BERT

WASHINGTON.

Telephone Numbers

Telephone numbers are stored in the database using standard
area code, exchange, and number format. All 10 digits of the
telephone number must be used.

Depending on your data collection and call tracking needs, you
may not want to differentiate calls based on all digits of telephone
numbers. The MERLIN Identifier system lets you substitute the
question mark (“?”) as a wild-card character in place of individual
digits in the telephone number.

34

MERLIN Identifier Database Description

Administering the MERLIN Identifier Database

Advantages of Using the
Wild-Card Character

Using one or more wild-card characters offers the following
advantages in storing telephone numbers in the database and
displaying Caller ID information:

■

■

■

■

Each wild-card character used in a telephone number
replaces 10 individual digits (0 through 9)—thus a single
wild-card character has the potential to reduce the
database by 9 records, two wild-card characters have
the potential to reduce the database by 99 records, and
so on

Selected ranges of telephone numbers could be assigned
to a single record

All telephone numbers within a calling exchange could be
represented by just a single database record

All telephone numbers within an area code could be
represented by just a single database record

The following examples show how the wild-card character can be
used to address business needs.

Example 1:

A local delivery service in the 901 area code has
been monitoring its telephone calls and finds that a significant
number of calls involved telephone numbers 555-4100 to
555-4199. A further check reveals that a single company uses all
100 of those telephone numbers. To use a single database record
to represent all 100 of the company’s telephone numbers, a caller
record with telephone number

901-555-41??

and the
company’s name has been set up in the MERLIN Identifier
database. Now any time a telephone order is placed from
telephone numbers 555-4100 to 555-4199, the delivery service
knows to send the delivery person to the same company.

MERLIN Identifier Database Description

35

Administering the MERLIN Identifier Database

Example 2:

The delivery service in “Example 1” only delivers
within a five mile radius. The manager has identified four
surrounding telephone exchanges outside the radius likely to
place an order, but to which deliveries would not be made: 332,
125, 976, and 212. To immediately identify those exchanges to
employees, the following telephone numbers were added to the
MERLIN Identifier database with the name

NO DELIVERY:

901-332-????, 901-125-????, 901-976-????,

and

901-212-????.

Now whenever a delivery request comes in
from those exchanges, the employee politely explains that the
location is outside the delivery range.

Setting Up and
Maintaining the Database

The MERLIN Identifier database enables you to match the names
of frequent callers to their telephone numbers. This database can
be set up in the following ways:

■

■

Using the Administrative Keyboard and Display or

When the MERLIN® Identifier is used with a MERLIN LEGEND

®

system having MLX™ sets, a pair of installer-wired 104A
termination outlets is required for each MLX set to be connected
to a MERLIN Identifier Display unit.

Figure 9 shows the location of the 104A termination outlets with
respect to the other MERLIN Identifier system components.
Figure 10 shows the internal “strapping” required for the 104A
termination outlets.
