3rd Edition,©1992 Muti-Link, Inc.

INTRODUCTION TO THE

WORLD

CALL PROCESSING

Your Versa-Link ATX-300 is a powerful Computer-

ized Call Processor that allows several telephone
devices to share a single phone line. Versa-Link is
compatible with standard telecommunication and
office equipment including: Facsimile (FAX)

machines, computer MODEMS, PC FAX Boards,
single and multi-line telephone systems, answering

machines, WATS lines, phone mail systems, credit
approval systems, and loop start TELEX equipment.

Versa-Link allows you to expand your present
communications network without installing an

expensive dedicated phone line for each device.
Versa-Link provides for greater utilization of phone

lines and office equipment.

1 .1 BASIC FEATURES

Versa-Link is a 24-hour communications control

center

that automatically analyzes and routes

incoming calls to the proper equipment. Your

Versa-

Link ATX-300 permits a caller to remotely access

your telephone, FAX machine, computer

MODEM, or

other equipment you may have attached. Standard

features include:

-

Auto FAX Detection - CALL

OPTI-MIZER

-

Automatic Ring-through to your

most-

used equipment

-

Manual Transfer - Calling Party

Hang-up Detect.

CALL OPTI-MIZER is a unique feature that makes
your phone line look more like a dedicated voice line
to voice callers, and more like a dedicated data line
to FAX or computer MODEM callers.

Calls can be manually transferred at any time by
either the caller or the called party.

Versa-Link’s data protection feature allows you to
transmit FAX or computer MODEM data without the
fear of someone disturbing the transmission by

picking up an extension phone. It also gives you

peace of mind knowing that your voice call will never

be interrupted by a FAX or MODEM.

VERSA-LINK ATX-300

2

Another unique feature is Versa-Links surge

suppressor, which provides added protection from

lightning strikes and voltage surges that could

damage your sensitive communications equipment.

1.2 CALL PROCESSING

Call processing is the task of routing telephone voice

and data calls to one of several destinations. Your

phone company can be considered a very large call

processor.

To better understand the principles behind call

processing, consider the following example:

l

A receptionist who answers all incoming calls

(in this case, the Versa-Link ATX-300)

l

A Customer Service Agent.

l

A sales agent.

l

A bookkeeper.

6

When a phone call comes in, the Versa-Link acts as
a receptionist and answers the call. If the caller

requests the sales agent or the bookkeeper by
dialing an access code, the Versa-Link transfers the
call to the proper party without disturbing anyone
else. If no code is dialed, the call is automatically
directed to the customer service agent for

information and further routing. The customer

service agent may re-direct calls to the sales agent

or bookkeeper by entering the proper access code.
Your ATX-300 can be used to process calls to your

voice and data equipment, just as it did in the above

example. If you are adding FAX and a computer

MODEM to a voice line, you have:

l

A Versa-Link ATX-300 that answers all calls

and transfers them to the proper device.

l

A telephone system that handles most calls.

l

A FAX machine. l A computer MODEM.

This is just one application. As you will see, your

Versa-Link is not just a switch. It’s a very smart call

processor that does exactly what it’s told to do, and

does it very well.

VERSA-LINK ATX-300

EQUIPMENT

Your Versa-Link ATX-300 is compatible with virtually
all modern telecommunications equipment, including
single and multi-line telephones. Because your
ATX-300 is installed between your telephone system
and the phone company, it

can direct all your tele-

phone traffic to the proper equipment. The most
popular types of equipment used with a Versa-Link
ATX-300 are described below.

2.1

FAX MACHINES

Your

ATX-300 has special features that work
extremely well with FAX machines and PC FAX
Boards. The Auto FAX Detection feature allows most
FAX calls to transfer to your FAX machine
automatically.

The vast majority of FAX machines sold today have

the ability to dial the number of the receiving FAX
from memory, and then identify itself as a FAX

machine with a tone (called CNG tone or AUTO-FAX

tone). It will then continue to identify itself until the

called FAX answers the call. When an ATX-300 is
used at the receiving end, it can detect this FAX
identification tone, and automatically transfer the call

to the FAX machine on the receiving end, without

ringing the telephone.

Occasionally, calls will come from a FAX machine
without a FAX identification tone. This may happen if
the calling person is using an older FAX machine, or

dials the number manually using the FAX handset. In
most applications, calls without this auto-FAX tone

will be routed to your telephone system. The call can

be manually transferred to the FAX machine by

dialing

* 2

(or another code, if re-programmed) on

your telephone keypad. Either the caller or the

person who answers can transfer the call. See

section 4.2.2 for details of operation.

VFRSA-LINK

ATX-300

4

EQUIPMENT

If possible, ask people who send you FAX messages

to program your number into their FAX machine’s

memory. This will allow FAX calls to always be

processed automatically.

2.2 COMPUTER MODEMS

Your ATX-300 is compatible with all dial-up MODEMS.

Usually, MODEM

S

are attached to the

DEVICE 3

connector of your ATX-300. Your ATX-300 will

transfer incoming calls to your MODEM when the

calling MODEM dials

* 3

(or another code, if
re-programmed) after the call has been answered
by your Versa-Link. The data protection feature
prevents interruptions from other telephone
equipment.

If your MODEM is only used for out-bound
communication, you do not need to be concerned

with the device selection code for the MODEM.
The device selection code for your MODEM is best

dialed by the calling MODEM. When calling your

MODEM attached to

DEVICE 3,

with the ATX-300’s

factory programming, the dialing command for a

Hayes-compatible MODEM would be:

I

ATDT 1 203 555 5678 , , , 3

I

The commas will generate pauses in the dialing

MODEM. The number of pauses may need to be
changed to allow enough time for the call to be
switched through the telephone company,
particularly if the calling MODEM is dialing

long-

distance.

The device selection codes can be changed- up to

seven digits to add security to any system. Your
ATX-300 will restrict access to only those callers

who dial the right device selection code. See section

7,

PROGRAMMABLE FEATURES,

to change this

code.

VERSA-LINK ATX-300

5

EQUIPMENT

Some MODEMS cannot dial the symbols * or #.
Therefore, if you plan to connect a computer
MODEM, it is best to change the device selection
code for your computer to an appropriate code that
does not use the symbols * or # .

2.3 TELEPHONES AND
MULTI-LINE SYSTEMS

Your

ATX-300

may be used with single and multi-line
telephone equipment. Both tone-dialing and pulse­dialing equipment may be used with your

ATX-300

See section 4.2.2 for restrictions when using pulse-

dialing equipment.

2.4 OTHER EQUIPMENT

Your ATX-300 is also compatible with

Credit
Authorization Terminals, Electronic Mail Terminals,
and Loop-Start dial-up TELEX machines.

Your

ATX-300

can also be used with answering

machines and cordless phones.

2.5

CALLER ID

DISPLAY

DEVICE

Your Versa-Link ATX-300 is now programmable to work

with the “Caller

ID" CLASS

service offered by your local

telephone company. See section 7.3 for programming

instructions. This feature allows the calling party’s phone
number to appear on your “Caller ID” display unit when

the ATX-300 routes the call.

VERSA-LINK ATX-300

6

APPLICATIONS

There are many applications for your Versa-Link
ATX-300

One unique advantage that Versa-Link

gives you is the ability to change its operation as

your business grows and your telephone needs

change.
A few of the popular applications are described here.

3.1

ADDING A FAX MACHINE

TO A

VOICE LINE

This application allows your

ATX-300

to auto-

matically direct all Auto-dialing FAX calls to your

FAX machine. All manually dialed FAX calls and all
voice calls will be directed to your telephone. You
can easily re-direct manually dialed FAX calls to
your FAX by pressing

*

2

(or another code, if
re-programmed) on your telephone. If desired,
another data device such as a computer MODEM
can be added.

As your business grows, you may want to make your

FAX line a dedicated line. Your ATX-300 can still give
you maximum utility of your phone lines. You may
want to re-configure your system to the application
described below to allow outgoing voice calls on this

FAX line.

3.2

ADDING

VOICE

TO

A FAX

LINE

In this application, your ATX-300 will direct all

incoming calls to your FAX machine when attached
to the DEVICE

1

connector on your ATX-300. When

your FAX is not in use, you will be able to use this

line for telephone calls.

VERSA-LINK ATX-300

APPLICATIONS

3.3 ALLOWING TWO OR MORE
DATA DEVICES TO SHARE
ONE TELEPHONE LINE

This application allows you to use up to three data
devices, such as FAX, MODEM, Credit Authorization
Terminal, etc. Normally, incoming FAX calls will be
directed to your FAX equipment. Data calls can easily

reach your MODEM or other equipment by dialing the

proper device selection code.

3.4 OTHER APPLICATIONS

Many configurations exist. For example, you can use

your ATX-300 to:

-

Screen incoming calls to your FAX, MODEM or
other data equipment. Alleviates “junk” FAX and
computer hacking.

-

Allow two or three offices to share a single line with
privacy.

-

Allow two or more answering machines to be used
together for stock quotations, dictation, daily results,
sports scores, new real estate listings, etc.

-

Allow remote cash register polling on an existing

telephone line.

VERSA-LINK ATX-300

8

OPERATION

Your ATX-300 will route incoming calls to
the proper equipment and prevent other
devices from interfering with the ongoing
communication.

4.1 OUTBOUND CALLS

When your

ATX-300

is operating in either

SEMI or AUTO modes, it will only allow one

DEVICE port to access the telephone line
at one time. For example, if you are send­ing or receiving a FAX, your telephones and
extensions will be unable to interrupt the
communication.

If you wish to transfer the call to another
device, you can do so by dialing the proper
device selection code. Either the caller or

the called party can transfer the calls. (see

section 4.2.2)

4.2 INCOMING CALLS

Incoming calls can be routed to your com­munications equipment in several ways.

-

Calls may be automatically transferred to
your FAX machine if the caller is a FAX that
produces a FAX identification tone.

-

Calls may be manually transferred by
entering touch tones from either end of the
line or with pulse dialing telephone equip­ment attached directly to your Versa-Link
ATX-300. In AUTO mode, tones may be
entered by the calling party any time after
the first ring. In SEMI mode, tones may only
be entered after the call is answered.

-

Calls can be transferred to your MODEM
if the caller is an auto-dial MODEM that
dials the proper device selection code.

-

All calls may be transferred to DEVICE 2
after hours if CALL

OPTI-MIZER

is acti-

vated.

VERSA-LINK ATX-300

4.2.1 Automatic FAX Transfer

Most FAX machines have the capability to dial the
receiving FAX number from memory. When the

number is dialed, an identification tone is produced
every 3-1/2 seconds that allows call processing
equipment, like your ATX-300, to identify the call as
originating from a FAX. When auto FAX tone
detection is turned on, your ATX-300 will transfer

these calls to DEVICE 2, where your FAX machine is

normally connected.

NOTE: Many FAX machines allow both voice and

FAX calls to be dialed manually from their keyboard.
Also, some older FAX machines do not have

auto-

dialing capability. These machines may not always

produce the necessary identification tone for

automatic transfer. Manual dialed FAX calls will ring
through to your telephone system and are easily
transferred to your FAX by dialing

* 2

It is possible for female voices to produce sounds of

the same pitch as the FAX identification (CNG) tone.

To avoid inadvertant transfers, your ATX-300 only

monitors the initial stage of incoming calls for CNG

tones. Also, in

SEMI

mode, your ATX-300 requires
two CNG tones at the proper interval before it
transfers the call automatically.

4.2.2 Manual Transfer

To transfer calls to a selected device, enter the

proper device selection code on your telephone (or
other equipment). The factory settings for the device
selection codes are:

Device Selection Codes

DEVICE 1

* 1

DEVICE 2

* 2

DEVICE 3

* 3

These device selection codes can be changed. See

section 7.2 for detailed information on changing

these codes.

VERSA-LINK ATX-300

10

OPERATION

The caller can manually transfer a call by using

I

touch-tone telephones or other equipment. The

called party can manually transfer a call with either

touch-tone or pulse-dialing equipment connected

through the ATX-300. If you plan to manually transfer
calls with a pulse-dialing telephone, change your
device selection codes to avoid the use of the

*

and

# symbols.

WHEN CAN I ENTER A DEVICE SELECTION CODE?

Device selection codes can be entered any time a
call is in process. In AUTO mode, a caller can start
entering device selection codes two seconds after
hearing the first ring. This allows calls to be
processed while the system is unattended.

CORRECTING MISTAKES

If

a

mistake is made entering

a device

selection
code, stop entering tones for five seconds or longer,
and reenter the correct device selection code.

4.2.3

CALL

OPTI-MIZER

Often it is desirable for all calls after hours and on
weekends to go directly to the FAX machine or
another automatic telephone device. This is
especially useful when expanding a voice line with

FAX and/or MODEM.

The primary application is for a company that has
several incoming lines with rollover. Only one

number is dialed by callers for voice traffic. If that line

is busy, the telephone company “rolls over” the call
to a second incoming line. If the second line is busy,
the call “rolls over”, and so on until the incoming call
finds a line that is not busy.

The last line is published as the FAX number. Any

incoming FAX call will ring in on-this line. During the

day, the last line is primarily used for voice, but may

also be used for both incoming and outgoing FAX.

However, at night, any call coming in on the last line

is assumed to be a FAX. This is because all other

lines would have to be busy for a voice call to come

in on this line.

TRANSFER DEFEAT

Dialing “80” on an inbound

call will cause your ATX-300

to

ignore all device selection
codes for the rest of that call.
This is useful if you are
calling into an answering
machine to get your
messages. This will prevent
tones that may be on your
incoming message tape from
accidentally transferring your
call.

1

VERSA-LINK ATX-300

11

OPERATION

The CALL OPTI-MIZER feature will count
the number of times the telephone (attached
to

DEVICE 1)

rings, after an incoming call

has been screened for Auto-dial FAX tones
and device codes. If the phone is not
answered in 5 rings (this number is pro­grammable

-

see section

7.3),

your

ATX­300 will assume that the office is unat­tended, and that this call and all future calls

should go to the FAX.

Your ATX-300 will immediately begin ringing
this call to the FAX. (If your FAX has

programmable ring selection, set it to

answer on the earliest possible ring)
At this time, your ATX-300 begins to operate

in NIGHT FUNCTION. Now, incoming calls

will ring your telephone system only 2 times

(programmable

-

see section

7.3),

and then

immediately ring the FAX. This will allow
future incoming calls to go to the FAX
sooner, with less chance of the caller

hanging up before the FAX answers.

NIGHT FUNCTION is de-activated when
you answer an incoming telephone call on
this line within 2 rings or make an outgoing
call on this line. Your ATX-300 will now
operate in normal daytime function. This

method of determining day/night/weekend is

much simpler than using a clock or calendar
which must continually be updated.

In the above example, a telephone system

was connected to

DEVICE

1,

and a FAX to

DEVICE 2.

Of course, the other devices

may be substituted to fit your application.

IN SUMMARY, CALL OPTI-MIZER can be

used when: (a) You want all calls after hours
to go to your FAX or MODEM on DEVICE 2

-

and - (b) You DO NOT have an answer-

ing machine on the same incoming line as

your FAX or MODEM.

CALL OPTI-MIZER can be used in either

AUTO

or

SEMI

modes. See section 7.1.3 to

activate CALL OPTI-MIZER.

4.2.4

CALLING PARTY

HANG-UP DETECT

Some local telephone companies have a
line disconnect function which is performed
at the central office switch. This disconnect
function detects the phone line voltage drop
that occurs when one party hangs up on a
call. The Versa-Link ATX-300 now has
“Calling Party Hang-up Detect” which
detects the line voltage drop, disconnects
the call routing and resets the Versa-Link for
new calls.

VERSA-LINK ATX-300

12

INSTALLATION

The following section covers installation of
your Versa-Link ATX-300 in various
applications.

Your “ATX-300 INSTALLATION MANUAL”
contains more detailed information about most
telephone systems and applications.

NOTE: You may want to call a local telephone
service company (listed in the Yellow Pages
under “Telephone Equipment and Service”) to
install the necessary jacks between the tele­phone company’s line and your internal wiring.

5.1

INITIAL

CHECK-OUT

Your ATX-300 shipping carton should contain

the following equipment:

-

Your Versa-Link ATX-300

-

An AC wall transformer with cord

-

One modular telephone cable

Plug the AC wall transformer into an electrical

outlet (110 Volt AC, 50-60 Hz) and plug its

power cord into the power connector on the
back of your ATX-300. The AUTO indicator on

the front of your ATX-300 should now be lit,

showing that power is supplied and the
ATX-300 is operating in AutoAnswer mode. If
either the STBY or SEMI indicators are lit,

then repeatedly press and release the mode

selector switch on the front panel until the
AUTO indicator is lit.

5.2 CONNECTING TO
THE PHONE LINE

WHAT LINE DO I USE?

Locate and identify the telephone line to which

you plan to attach your ATX-300. If you are

using a multi-line telephone system with
rollover, use the last line in the rollover
sequence.

WHERE DO / CONNECT MY

ATX-300

Locate a point on the line between the
telephone company and all existing telephone
equipment and extensions attached to this

line. Disconnect all telephone equipment and
extensions from the telephone line. They will

later be re-connected to the telephone line
THROUGH your ATX-300. You may need to

install RJ-11 jacks to facilitate installation of
your ATX-300.

IMPORTANT: One function of your ATX-300 is
to receive incoming calls and then distribute
them to the proper equipment. For this reason

it is VERY important that your ATX-300 be
installed ahead of all existing telephone
extensions and equipment.

The ATX-300 should now be the only device
connected to this telephone line.

5.3

RE-CONNECT
YOUR TELEPHONE
SYSTEM

If you are using this line for voice communi­cation, you will need to reconnect your

telephone system THROUGH THE ATX-300.

First, you will want to determine what type of

phone system you have.

you have extensions, attach the

DEVICE 1

connector to one of the extension jacks. This
will re-connect all the extensions.

telephones

If you are using a multi-line Key system,
attach your KSU telephone input for the
selected line to the

DEVICE 1

connector on

the back of your ATX-300.

NOTE: Your ATX-300 is not designed to
operate at a station port of a KSU. It will only
operate on the trunk side of a key system.

If

you are using a two-line feature phone
system with no controller (called an RJ-14
system), connect the telephone cable
attached to the selected line of your dual line
phone system to the

DEVICE 1

connector on

the back of your ATX-300.

5.3.3 PBX (Private

Branch

Exchange)

Your

ATX-300

can be used at a station

extension of any PBX. It can also be used on

the trunk side of most loop-start

PBX's.

Whether you are installing your ATX-300 on a
station extension or on a PBX trunk, first verify

that the circuit is compatible by testing it with

a single-line telephone. If you are unable to
get a dial tone, the line is not compatible.

WARNING: Improper connections to PBX

extensions and trunks can cause damage to

telephone equipment If you are in doubt,

contact your local telephone service company

Products are available to allow use of

loop-

start equipment on a ground-start PBX trunk.

Contact your local telephone service company

or our technical experts here at Multi-Link.

5.4 ATTACHING OTHER

DEVICES

(FAX,

MODEM, ETC.)

When you attach your FAX, computer
MODEM, credit terminal, or other equipment,
set the equipment to answer incoming calls on
the first or second ring, if possible.

How you attach your data equipment depends

entirely on what you want your system to do.

Some of the most popular applications are
listed on the next page:

INSTALLATION

5.4.1 Adding FAX to a
voice line

When adding FAX to a voice line, attach your
FAX to the

DEVICE 2

connector on the back

of your

ATX-300

See your installation manual

for details.

f

Operate your

ATX-300

in

AUTO

mode. Also,
activate auto FAX tone detection. Configu­ration switches 1 and 6 should be set to the
“up” position. This is the factory setting.

If necessary, change the configuration
switches on the back of your

ATX-300.

Unplug
the ATX-300 power cord for about 2 seconds
and re-connect it to activate the new settings.

In addition, you may also want to turn on CALL
OPTI-MIZER

if you are using your ATX-300
on a multi-line system. See section 4.2.3 for
details.

5.4.2 Adding voice to a

FAX line

If you are expanding the use of your FAX line
you will want to move your telephone system

to the

DEVICE 2

connector and attach your

FAX machine to DEVICE

1.

This will allow all
incoming calls to go directly to your FAX
machine. Outbound calls can be made as

.
usual, and incoming calls are possible using
manual transfer.

You will want to disable auto FAX tone
detection. Set the configuration switch position
6 to the “down” position.

Unplug the power cord from your

ATX-300

for
about 2 seconds and re-connect it to activate
the new switch settings.

In addition, you may want to operate your

ATX-300 in

SEMI

mode if 100% of the
incoming traffic for this line will go to the FAX
machine. See section 6.2 for a description of
SEMI mode.

5.4.3

Allowing two or more

data devices to share
one line

If you are using FAX, attach your FAX
machine to the

DEVICE 1

connector on the
back of your ATX-300. Attach your other data
devices to the

DEVICE 2

and

DEVICE 3

connectors.

VERSA-LINK ATX-300

15

INSTALLATION

If you are not using FAX, choose the data
device that most of your incoming calls should
go to. Attach this device to the

DEVICE 1

connector on the back of your ATX-300.
Attach the other data devices to the

DEVICE

2

and

DEVICE 3

connectors.

If you are not using FAX, or if your FAX is

attached to

DEVICE 1, you should disable

auto

FAX detection. Set the configuration

switch position 6 to the “down” position.

Unplug the power cord from your ATX-300 for
about 2 seconds and re-connect it to activate

the new switch settings.

5.4.4 Adding an answering
machine

If you use an answering machine, attach it to

the same connector that your telephone

system is attached to. You

may

either connect
your telephone system through your answer­ing machine, if a connector is provided on the
answering machine for that purpose, or you
may need to use a multi-outlet Y-adapter.

You may also want to leave instructions on the
outgoing message to instruct callers on how
to access your data equipment. If you have a

FAX

attached to DEVICE 2, remember to give

out your device selection

code for access to

your

FAX, so

that callers with manually dialed

FAX machines can send you messages while

you are not there. A sample message might be:

“Hello, this is

.

If you

would like to leave a

FAX message, press

star-two to ring our

FAX machine. If you

would like to

leave a voice message,
please begin speaking after the tone.
Thank you for calling.”

Depending on your application, you may want

to change the factory settings of the configu-

ration switches or change the device selection

codes.

For a detailed description of all the operational
features, and step-by-step information on how
to program them, see section 7,

PROGRAM-

MABLE FEATURES.

5.6 GENERAL RULES OF

INSTALLATION

When installing your ATX-300, there are three
general principles to keep in mind:

5.6.1

Your ATX-300 must be the only device
directly connected to the telephone
company’s incoming line.

There cannot be
any extensions or data devices connected in
parallel with your ATX-300 on this line. All
extensions and data devices must be
connected to one of the DEVICE ports on

the back of your ATX-300.

VERSA-LINK ATX-300

16

INSTALLATION

For example, if you connect your ATX-300 in

the following way, it will not function properly:

Ringing will be heard in the background if a
call is answered by one of the extension
phones. Also, your

ATX-300

cannot prevent
an extension phone from being lifted and
interrupting a FAX call.

For the same reason, party lines and

off­premise extensions (OPX), including
answering services located away from your
building, are not compatible with your

ATX-300. Do not install an ATX-300 if you are
on a party line or have an OPX.

5.6.2

Your ATX-300 is intended for use with
standard modular

RJ-11

jacks.

Many key

system station jacks look the same, but are

not wired for the RJ-11 standard. In addition,

some ground-start PBX trunks are

incompatible. Neither an ATX-300 nor a FAX
machine will operate if connected to this point.

The general rule is: if a SINGLE-LINE
telephone will work on the connector, your
ATX-300

will work. You can usually use a
telephone line tester to verify that the jack is
wired for RJ-11.

5.6.3

Manual transfers are accomplished by

entering touch-tones or dial pulses.

Some
multi-line key systems do not allow tone dial
pulse generation on incoming calls. To

determine if the key system is capable of

manually transferring an incoming call, call

the line on which you wish to install your
ATX-300 from another location, and listen to
determine if the person who answers can dial
touch-tones or pulses.

Pulse-dialing telephone equipment and some
key systems do not always generate the

*

or
# signals. You can overcome this limitation
by changing the

ATX-300

device selection

codes to new codes that do not contain * or

#

. See section 7.2 to change device

selection codes.
On a few key systems, dialing

* #

will

unlock the key pad to once again dial

touch-

tones. Try dialing * # * 2, for example, to

manually transfer to your FAX machine.

On some key systems that do not allow tone
generation on inbound calls, you can fool the
telephone system into thinking it is making an
outbound call by p

ressing the “FLASH” key,
and then dialing * 2 To keep from hanging
up the caller, activate the “Protected Hook
Flash” feature. See section 7.1.5.

VERSA-LINK ATX-300

OPERATING MODES

Your Versa-Link ATX-300 has three modes of
operation: AUTO-Automatic answer, SEMI­Semi-automatic answer,k STBY-Standby.

The operating mode is shown at all times by
the indicators on the front panel. You can
change the operating mode by pressing and

releasing the mode selector switch on the
front panel. This mode remains in effect until
you change it by pressing the switch again, or
until power is removed from your ATX-300.
You can set the start mode on power up by
changing the

configuration

switches on the

back of

your ATX-300

See section 7.1.1.

6.1AUTO-AUTOMATIC
ANSWER

In AUTO mode your ATX-300 will answer
incoming calls and produce a simulated

ringback tone to the caller. Your ATX-300
waits about six seconds longer before it
begins to ring DEVICE 1. During this time

the

caller may manually transfer the call by

dialing
a device selection code. Your ATX-300 is also
screening the call for auto FAX tones.

If no auto FAX tone is detected, and if no device
selection codes are entered, your ATX-300
will begin to ring the equipment attached to
DEVICE 1. Once connected, your ATX-300
will isolate equipment attached to the other
device ports for the duration of the call.

The call can be manually transferred at any
time by either party. There is no limit to the

number of times the same call can be
transferred. During transfers, the caller is put

on hold, and hears a

ringback

signal while the
selected device is being rung. All devices that
are not selected are disconnected from the

telephone line.

When the line is not in use, any device can
place an outgoing call. During this time, all
other devices are disconnected from the

incoming line.
In AUTO mode, long distance charges begin

when your ATX-300 answers incoming calls.

6.2 SEMI-SEMIAUTOMATIC
ANSWER

In SEMI mode, incoming calls ring straight
through to DEVICE 1. In SEMI mode, your
ATX-300 does not answer the call itself, so all

incoming calls will ring DEVICE 1 initially.
When the call is answered, your ATX-300.

begins to listen for device selection codes and
auto FAX tones. If a valid device selection
code or auto FAX tone is heard, your ATX-300
places the call on hold and rings the selected
device. The caller will hear a

ringback

tone

while your ATX-300 rings the selected device.
A call can be manually transferred any time

after the call has been answered.
When the line is not in use, any device can

place an outgoing call. Just as in AUTO

mode, your ATX-300 disconnects all other
devices while a call is under way.

In

SEMI

mode, long distance charges begin

when a device answers an incoming call.

SEMI mode is especially useful with an

answering machine connected to DEVICE 1.

6.6

STBY-STANDBY

MODE

In standby mode, all device ports are con-

nected to the incoming line. No call screening

is performed, and no transfers can be made.

Incoming calls ring all devices.

STBY mode is especially useful for trouble-

shooting your building wiring. When no power

is applied to your ATX-300, it will operate as if

it were in standby mode.

6.4 NOTES ON OPERATION

When your ATX-300 is ringing a device, it will

attempt six rings to that device. This number is

programmable-see section 7.3. If the selected

device does not answer within this period,

your ATX-300 will disconnect the call and

restore all devices to their original condition.

IMPORTANT: Configuration switch changes
are not activated until AC power is re-applied.
Therefore, unplug and re-connect the AC

power cord after making any configuration
switch changes to enter these settings into
memory.

7.1.1 START-UP MODE

After a power outage you will want your
ATX-300 to enter the proper mode of
operation. Normally the AUTO or SEMI mode

is selected as the desired start-up mode.

CHANGING THE

START-UP MODE

Configuration switches 1 and 2 are used to
select your start-up mode. Remember to

unplug and re-connect the AC power after

changing the configuration switch.

7.1.2 FAX TONE
SELECTION

If you connect a FAX machine to your
network, you will need to tell your ATX-300

which

DEVICE

port it is on. This allows auto-

dial FAX calls to be transferred to your FAX

machine automatically.
If you are adding FAX to a voice line, connect

the FAX to

DEVICE 2.

If you are expanding a FAX line, connect the

FAX to

DEVICE 1.

7.1.4 ADDITIONAL RING

DELAY

There are situations where the first ring-delay

in

AUTO MODE

(about 6 seconds) is not long
enough to allow a FAX tone or device
selection code to be generated by the

transmitting device.

Specifically, there are a few models of

auto­dialing FAX machines, including many made
by NEC, which do not immediately begin
generating the auto-dial FAX tone after dialing

the telephone number. Also, it is sometimes

difficult to program a MODEM to produce a
device selection code at the proper time:

(AFTER the call has been answered by your

ATX-300, but BEFORE the ATX-300 begins to

ring

DEVICE

1).

You can program your ATX-300 to wait one
additional ring (for a total of about 12 seconds)

before ringing

DEVICE

1. This will allow
MODEMS and slow dialing FAX machines
more time to transmit the proper signals.

CHANGING THE

ADDITIONAL RING DELAY

Configuration switch
4 is used to select

additional ring delay.

7.1.5

PROTECTED HOOK

FLASH

Your

Versa-Link ATX-300 has an additional

feature, Protected Hook Flash, that allows it to

be compatible with key system telephones

that do not allow tone dialing on inbound calls.

In the past, this would sometimes prevent you

from manually transferring calls to your FAX,

MODEM, or other device.

On some key systems that do not allow tone
generation on inbound calls, you can fool the
telephone system into thinking it is making an
outbound call by pressing the “FLASH” key,
and then dialing the proper device code.

For example, if your FAX is connected to
DEVICE 2, and the device selection code for
DEVICE 2 is * 2, calls can be manually

transferred to the FAX by pressing “FLASH”

and then * 2

To prevent the caller from being hung up
when the FLASH key is pressed, you will want
to activate Protected Hook Flash. This will

place the call on hold while the flash button
momentarily disconnects the line. Protected
Hook Flash should not be used if your phone

is pulse-dial.

CHANGING THE

PROTECTED HOOK FLASH

Configuration switch 3 is used to select

Protected Hook Flash. Remember to unplug
and reconnect the AC power after changing
the configuration switch.

PROGRAMMABLE
FEATURES

7.2 DEVICE SELECTION
CODES

Your

ATX-300 analyzes incoming calls for
(DTMF) touch-tones and analyzes your
equipment for both pulse-dial and touch-tone
device selection codes. Device codes are
programmable and may be from 2 to 7
characters long using any combination of the
digits 0 to 9

and the symbols

*

and #. Do
not use numbers that are the same as the
beginning of actual local telephone numbers
or area codes. Using the symbols

*

or # is
a good way to avoid unwanted transfers when
dialing.

If your equipment is pulse-dial only, you
cannot use the symbols

*

or

#

CHANGING YOUR

DEVICE SELECTION CODES

NOTE: If at any point in the programming
process you are unsure and would like to
start again, unplug the AC power cord and
re-connect it. Your ATX-300 will enter its
start-up mode and you can start over with
step 1.

The device selection codes are programmed
by pressing keys on a tone or pulse-dialing
telephone attached to one of the DEVICE
connectors on the back of your ATX-300.
The incoming telephone line must also be
attached to the ATX-300 LINE connector.

While you are entering digits on your
telephone to program your ATX-300, you are
also dialing those numbers to the telephone
company. To avoid dialing through to another
number, we suggest that you either establish
a local call while programming (dial one of
your other lines if you have more than one
line), or hang up the phone between each
device code. This will not affect the
programming process.

1)

HOLD the front panel switch in for about 3
seconds until the STBY LED indicator starts
blinking.

2) Release the push button switch. The STBY
LED will remain blinking. If you would like to
change the selection code for DEVICE 1 then

enter the new code on a telephone keypad. If

no code is entered at this point the old code

will remain in effect (continue with step 3).

3) PRESS and immediately RELEASE the
push button switch. The SEMI LED will now
be blinking. If you would like to change the

selection code for DEVICE 2 then enter the

new code on a telephone keypad. If no code
is entered, the old code remains in effect
(continue with step 4).

4) PRESS and immediately RELEASE the
push button switch. The AUTO LED will now
be blinking. If you would like to change the
selection code for DEVICE 3 then enter the
new code on a telephone keypad. If no code
is entered, the old code remains in effect
(continue with step 5).

5) HOLD the front panel push button switch in
until the

AUTO

LED stops blinking. Release

the push button switch. One of the three

LED’s will light up, indicating the current
operating mode.

7.3 CALLER I.D.
PROGRAMMING

The “Calling Number I.D.” service provided by
your

local telephone company allows you to
see the number of the calling party before you
answer the phone. The phone number
appears on your Call Identifier display device
between the first and second ring.

Normally, your ATX-300 answers incoming

calls immediately after the first ring. This does

not give the “Caller Number I.D.” service

enough time to show you who is calling. A

new programmable feature has been added

that will give your ATX-300 “Calling Number

I.D.” compatibility be delaying its answer time

by 3 seconds.

VERSA-LINK ATX-300

21

PROGRAMMAELE
FEATURES

To program your ATX300 for “Calling

Number I.D.” compatibility:

1. Attach a tone-dialing phone to a device
port of the ATX300. Attach the line connec-

tor to an incoming telephone company line.

2. Hold the front panel push button switch in
for at least 3 seconds until the STBY

indicator light begins to blink. Release the

push button switch.

3. Pick-up the handset of the telephone you
have attached to your ATX-300.

7.7

PROGRAMMING TIPS

Since the length of each device selection
code can be from two to seven digits, and
each of the three devices can have a
selection code of different length, you can
custom tailor your codes to allow easy access
with two or three-digit codes, or increase your
security with longer codes. If you use an
answering machine, you may also want to
announce to callers how they can manually

transfer calls to certain devices.

Care should be taken not to program a device
selection code that is the first part of another
code. For example, if DEVICE 2 has a
selection code of “99” and DEVICE 3 has a
selection code of

"999",

DEVICE 3 will never
be selected, because when the “99” code is
entered, DEVICE 2 will be immediately
selected.

It is also recommended that the device

selection code never be the first part of any

normally dialed telephone number. For

example, the code “12” would not be a good

choice, because a long-distance call to Los

Angeles would require dialing

"1-213-

..

."".

After the “12” is heard, your

ATX-300

would
then transfer the call and not allow you to
finish dialing. This is why the symbols

*

and

#

are often good choices for the first or

second digit of a device code.

COMMONLY

ASKED

QUESTIONS

Before you contact your Versa-Link dealer or
distributor about a question, please read this
section. If you are experiencing a problem,
you may be able to quickly solve it yourself.

WHY DO SOME FAX CALLS GO TO MY
TELEPHONE?

Sometimes FAX calls originate from
equipment that does not identify itself as a

FAX machine. You can manually transfer the
call by dialing the device selection code for
your FAX (factory set to

*

2

). See section

2.1. Activating CALL OPTI-MIZER may

eliminate this problem at night. See section

4.2.3 for details.

Also, you may need to change auto-FAX tone
detection. See section 7.1.2.

WHY DO I SOMETIMES GET A BUSY

SIGNAL WHEN I PICK UP THE

TELEPHONE RECEIVER?

The busy signal you receive is from the
“barge-in” protection feature on your

ATX-

300. It means the phone line is being used

by either your FAX or MODEM. Wait for the
equipment to finish data transmission and
then try your telephone again.

COMMONLY

ASKED

QUESTIONS

AFTER I CHANGE THE

CONFIGURATION
SWITCHES, WHY DOES THE ATX-300 NOT
CHANGE ITS OPERATION?

Any time you change the configuration

switches on the back of your ATX-300, you
must unplug its power cord for about two
seconds to activate the new settings.

WHY DOES MY ATX-300 REPEATEDLY

CLICK-CLICK WHEN

I

PICK UP THE LINE?

If you cannot get a dial tone, and only hear a

click-click every two seconds or so, the

ATX-300 does not have a good connection to

the phone company. Check your installation

and wiring for loose or open connections.
Connect a single-line telephone directly to the
incoming

line. Check for dial tone and proper
operation. A dead line should be reported to
your telephone company.

WHY DOES MY FAX ANSWER ALL

INCOMING CALLS?

Your ATX-300 may be operating in

STBY

(standby) mode, or it may not be getting any
power. Check the LED indicators on the front

panel. If no indicators are lit, check the power
connector, the AC adaptor, and the AC power
source.

get a dial tone on any of your telephones, your
installation is not correct.

GLOSSARY

EQUIPMENT:

CALL PROCESSOR

-

A device that manages
telephone traffic and routes incoming calls to
the proper equipment. The ATX-300 call

processor analyzes and routes incoming calls

to your telephones or data equipment.

FAX (FACSIMILE) MACHINE

-

A device that

attaches to your telephone line and is capable
of scanning a document, electronically
transmitting and receiving the image, and

printing the image. (sometimes called

“TELEFAX” or “TELECOPIER”)

PC FAX BOARD

-

A circuit board that is
installed in a personal computer. Like a FAX, it
attaches to your telephone line and is capable
of transmitting and receiving images with
other FAX Boards and FAX machines. A
FAX board, when used with a printer and
document scanner, operates like a modern
FAX machine.

MODEM

-

A device that allows computers and
other electronic equipment to communicate
through ordinary telephone lines.

KEY TELEPHONE SYSTEM

-

A multi-line
telephone system with extension telephone
sets. A Key system always has a Key System
Unit (KSU) controller that all telephone sets
attach to. Also, the Key system telephone sets
have a series of buttons that are used to
select the outside line you wish to use.

KSU (KEY SYSTEM UNIT)

-

The controller
that manages a multi-line Key telephone
system. All incoming telephone lines and all
telephone sets connect to the KSU. The KSU

is usually mounted in a back room or

telephone closet of the off ice it serves.

PBX (PRIVATE BRANCH EXCHANGE)

--

An

VERSA-LINK ATX-300

25

GLOSSARY

electronic multi-line telephone system, used
primarily in very large applications with many
extensions. The identifying feature of most
PBXs

is that you must dial

9

to get an

outside line.

PBXs

generally use standard

single-line telephones at extension locations.

TONES:
DTMF (DUAL TONE, MULTI-FREQUENCY)

-

This tone is commonly called “touch-tone”.

Not all push-button phones are capable of
producing the DTMF tones.

AUTO FAX TONE (CNG)

-

This tone is
produced by virtually all FAX machines
when it dials the receiving FAX machine’s
number from memory. Older FAX machines
and some current models that do not have
speed-dial memory will not produce CNG.
CNG is a medium-pitch tone

(1100

Hz)

that

lasts

1/2

second and repeats every 3-1/2

seconds. A

FAX machine will produce CNG

for about 45

seconds after it dials the

receiving FAX number.
CARRIER AND DATA

-

A very loud screech

that is produced when the FAX machines or

MODEMS are actually transferring data. Unlike
CNG or DTMF, carrier and data will be
constantly changing.

RINGBACK -

A tone produced by telephone
processing equipment that signals to the
caller that the called party is being rung. Your
ATX-300 produces a

ringback

tone to the

caller when ringing a device.

OTHER TERMS:

CO (CENTRAL OFFICE) -

Your telephone
company. Your CO is the building where your
telephone line is electronically managed.

TIP AND RING - An archaic term that gets its
meaning from the old switchboard plugs. Each
plug had a tip connector and a ring connector.

Now, tip and ring refer to the two conductors

that make up a single telephone line.

ON-HOOK

-

Another old term that gets its

meaning from your telephone handset resting

on the hook switch. If equipment is “On-hook”,

it is idle and not using the telephone line.

OFF-HOOK - If equipment is “off-hook”, it is

not idle but actively connected to the

telephone line.

MODULAR CONNECTOR - A catch-all term

that describes a number of plugs and jacks

used with telephone and other equipment.
Handset connectors have four contact
positions. Line connectors are wider and have
six positions (often, only two or four positions
are loaded with contacts).

RJ-11 WIRING STANDARD

-

A specific wiring

arrangement for using a

6-position

modular
connector to attach exactly one telephone line.
The two wires of the telephone line are
attached to the two center contacts of an

RJ-

11 modular jack (the wires are often

color­coded red and green). All connections to your
ATX-300 must be wired according to this

RJ-

11 standard.
RJ-14 WIRING STANDARD

-

Utilizes a six

position modular connector wired to two

separate telephone lines. This application is

used almost exclusively on dual line tele-

phones. Line 1 is attached to the center two

contacts (like RJ-ll), and Line 2 is attached to

the next outer two contacts (often color-coded

yellow and black).

POLARITY - A term used to describe the

order of two electrical points

-

one positive

and the other negative. On an RJ-11 female

jack, the green lead should be positive with

respect to the red lead to ensure proper
operation with all equipment.

TRUNK - A line that connects to the
telephone company

CO

(central office).

LOOP START - A line or equipment that will

establish a dial tone by completing a circuit

between the two wires of the line. Your

ATX-

VERSA-LINK ATX-300

26

GLOSSARY

300, all FAX machines and single-line phones,
and most MODEMS are loop start equipment.

GROUND START

-

A line or equipment that
establishes a dial tone by completing a circuit
between one of the wires of the line and earth
ground. Ground start circuits are used mainly

for PBX applications. Loop start equipment

will not operate if connected directly to a
ground start line.

PARTY LINE

-

A line that serves more than
one subscriber or user. Your ATX-300 cannot
be properly operated on a party line system.

OPX (OFF PREMISE EXTENSION) - Like a
party line, an OPX is a line that serves more
than one subscriber location. Examples of
OPXs

are off-premise answering services,
and lines that serve more than one building.
Your ATX-300 will not operate fully if attached
on a line with an OPX.

STATION

-

A telephone set attached to a

multi-line Key system or PBX. Your

ATX-300

will work on a PBX station extension, but WILL

NOT work on a Key system station extension.
EXTENSION - A catch-all term that describes

additional phones attached to a single line (as
in a residence or small office) or a station of a
Key system or PBX.

ROLL-OVER - A service provided by most
phone companies that allows several lines to
be tied together. A single number is generally
dialed by all callers. If that line is busy, the
phone company will “roll-over” the call to
another line in that group. Also called

"hunt-

group” or “rotary”.

ROTARY - An ambiguous term. “Rotary

Group” means a roll-over group, and “Rotary

Dialing” means pulse dialing.

CALL WAITING

-

A feature provided by many
telephone companies that allows two calls to
be managed at the same time on one line.
Your ATX-300 will work fine with “Call
Waiting”, but your FAX or MODEM probably
won’t Call Waiting is not recommended for
lines used for data transfer.

SERVICE/WARRANTY

INFORMATION

FCC REGISTRATION

This equipment complies with Part 68 of the

FCC rules. On the bottom of this equipment is
a label that contains, among other information,

the FCC Registration Number and Ringer

Equivalence Number (REN) for this equip­ment. You must, upon request, provide this
information to your telephone company.

The REN is useful to determine the quantity of
devices you may connect to your telephone

line and still have all of those devices ring
when your telephone number is called. In
most, but not all areas, the sum of the

RENs
of all devices connected to one line should not
exceed five (5.0). To be certain on the number
of devices you may connect to your line, as
determined by the REN, you should contact

your local telephone company to determine

the maximum REN for your calling area.

If your telephone equipment causes harm to
the telephone network, the telephone
company may discontinue your service
temporarily. If possible, they will notify you in
advance, But if advance notice isn’t practical,
you will be notified as soon as possible. You
will be informed of your right to file a complaint
with the FCC.

Your telephone company may make changes
in its facilities, equipment, operations or

procedures that could affect the proper

functioning of your equipment. If they do, you

will be notified in advance to give you an

opportunity to maintain uninterrupted
telephone service.

If you experience trouble with this telephone

equipment, please contact your Versa-Link

dealer or Multi-Link, Inc. for information on

obtaining service or repairs. The telephone

company may ask that you disconnect this

equipment from the network until the problem

has been corrected or until you are sure that
the equipment is not malfunctioning.

This equipment may not be used on coin
service provided by the telephone company,
and is not intended for use with party line
service. This equipment is intended for use
only on loop-start service, and will not
operate on a ground-start central office line.

DOC REGISTRATION

The Department of Communications label
identifies certified equipment. This certifica­tion means that the equipment meets certain
telecommunications network protective,
operational and safety requirements. The
Department does not guarantee the equip­ment will operate to the user’s satisfaction.

Before installing this equipment, users
should ensure that it is permissible to be
connected to the facilities of the local
telecommunications company. The equip­ment must also be installed using an
accepted method of connection. In some
cases, the company’s inside wiring associ­ated with a single line individual service may
be extended by means of a certified connec-

tor assembly (telephone extension cord). The
customer should be aware that compliance
with the above conditions may not prevent
degradation of service in some situations.

Repairs to certified equipment should be
made by an authorized Canadian mainte­nance facility designated by the supplier. Any
repairs or alterations made by the user to this
equipment, or equipment malfunctions, may
give the telecommunications company cause
to request the user to disconnect the
equipment.

Users should ensure for their own protection
that the electrical ground connections of the

power utility, telephone lines and internal

metallic water pipe system, if present, are

connected together. This precaution may be

particularly important in rural areas.
