VERSA-LINK ATX-250

INTRODUCTION TO THE WORLD OF
CALL PROCESSING
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-250
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.
Your Versa-Link ATX-250 is a powerful Computerized Call
Processor that allows more than one telephone device to
share a single phone line. Versa-Link is compatible with
/
standard telecommunication and off ice equipment
including: Facsimile (FAX) machines, computer MODEMS, -
PC FAX Boards, single and multi-line telephone systems, /
VERSA-LINK ATX-250 2

INTRODUCTION
Another unique feature is Versa-Links surge suppressor
which provides added protection from lightning strikes a
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-250)
l A Customer Service Agent.
l A sales agent.
When a phone call comes in, the Versa-Link acts as a
receptionist and answers the call. If the caller requests the
sales agent by dialing an access code, the Versa-Link will
transfer the call 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 by entering the proper access code.
Your ATX-250 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 or a computer MODEM to a voice line,
you have:
l A Versa-Link ATX-250 that answers all calls
and transfers them to the proper device.
l A telephone system that handles most calls.
l A FAX machine or 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-250 3

EQUIPMENT
Your ATX-250 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-250 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 selected
code) 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.
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.
Your Versa-Link ATX-250 is compatible with virtually all
modern telecommunications equipment, including single
and multi-line telephones. Because your ATX-250 is
installed between your telephone system and the phone
company, it can direct all your telephone traffic to the
proper equipment. The most popular types of equipment
used with a Versa-Link ATX-250 are described below.
2.1 FAX MACHINES
VERSA-LINK ATX-250
4

EQUIPMENT
2.2 COMPUTER MODEMS
Your ATX-250 is compatible with all dial-up MODEM S .
Usually, MODEM S are attached to the DEVICE 2
connector of your ATX-250. Your ATX-250 will transfer
incoming calls to your MODEM when the calling MODEM
dials *2 (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. For example, when calling into a
MODEM attached to
DEVICE 2, with the ATX-250 factory
programming, the dialing command for a
Hayes
compatible MODEM would be:
I
ATDT 1 203 555 1234 ,,,,*2
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 selectable device codes can be reconfigured to add
security to any system. Your ATX--250 will restrict access
to only those callers who dial the right device selection
code. See section 6,
USER SELECTABLE FEATURES, to
change this code.
Some MODEM
S cannot dial the * symbol. Therefore, if
you plan to connect a computer MODEM, it is best to
choose a device selection code for your computer that
does not use the * symbol.
VERSA-LINK ATX-250
5

OPERATION
Your ATX-250 will route incoming calls to the proper
equipment and prevent other devices from interfering with
the ongoing communication.
4.1 OUTBOUND CALLS
Your ATX-250 will only allow one DEVICE port to access
the telephone line at a time. For example, if you are
sending or receiving a FAX, your telephones and
extensions will be unable to interrupt the communication. If
you pick up your phone or FAX and hear a busy signal,
then another device is already using the line.
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 dialing touch
tones from either end of the line or with pulse-dialing
telephone equipment attached directly to your
Versa-
Link ATX-250. Tones may be entered by the calling
party any time after the first ring.
- 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 automatically transferred to DEVICE 2
after hours if CALL
OPTI-MIZER is activated.

EQUIPMENT
2.3 TELEPHONES AND MULTI-LINE
SYSTEMS
Your ATX-250 may be used with single and multi-line
telephone equipment. Both tone-dialing and pulse-dialing
equipment may be used with your ATX-250. See section
4.2.2 for restrictions when using pulse-dialing equipment.

PBX
2.4 OTHER EQUIPMENT
Your ATX-250 is also compatible with Credit Authorization
Terminals, Electronic Mail Terminals, and Loop-Start
dial-
up TELEX machines.
Your ATX-250 can also be used with answering machines
and cordless phones.
2.5 “CALLER ID” SERVICE
COMPATIBILITY
Your ATX-250 is now programmed to wait for and detect the
transmission of “Caller ID” data. This function allows the calling
party’s phone number to appear on your “Caller ID” display unit
before your ATX-250 routes the call to any device.
VERSA-LINK ATX-250 6

APPLICATIONS
There are many applications for your Versa-Link ATX-250.
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-250 to automatically
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.
As your business grows, you may want to make your FAX
line a dedicated line. Your ATX-250 can still give you
maximum utility of your phone lines. You may want to re-
configure your system to allow outgoing voice calls on this
FAX line.
3.2 ADDING A MODEM TO
A VOICE LINE
This application allows your ATX-250 to direct all voice
calls to your telephone, and allow incoming computer
MODEM calls to access your MODEM with the proper
device code.
VERSA-LINK ATX-250
7

APPLICATIONS
3.3 ADDING VOICE TO A
FAX LINE
In this application, your ATX-250 will direct all incoming
calls to your FAX machine when attached to the DEVICE 1
port on your ATX-250. When your FAX is not in use, you
will be able to use this line for telephone calls.
3.4 ALLOWING TWO DATA
DEVICES TO SHARE ONE
TELEPHONE LINE
This application allows you to use two data devices, such
as FAX, MODEM, Credit Authorization Terminal, etc.
Normally, incoming 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.
3.5 OTHER APPLICATIONS
Many configurations exist. For example, you can use your
ATX-250 to:
- Screen incoming calls to your residence while allowing
individuals with your selectable access code to bypass
the answering machine.
- Allow two offices to share a single line with privacy.
- Allow two 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-250 8

OPERATION
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-250, to identify the call as originating from a FAX.
When auto FAX tone detection is turned on, your ATX-250
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
sy
stem 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-250 only monitors the
initial stage of incoming calls for CNG tones.
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 are:
Device Selection Codes
DEVICE 1 *3
DEVICE 2
*2
These device selection codes can be changed. See
section 6.1 for detailed information on changing these
codes.
The caller can manually transfer a call by using touch-tone
telephones or other equipment.
VERSA-LINK ATX-250 10

OPERATION
The called party can manually transfer a call with either
touch-tone or pulse-dialing equipment connected through
the ATX-250. If you plan to manually transfer calls with a
pulse-dialing telephone, choose device selection codes
that do not use the * symbol.
WHEN TO ENTER A DEVICE SELECTION CODE
Device selection codes can be entered any time a call is
in process. 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 two seconds or longer, and re-enter the
correct device selection code. If you are dialing on a
pulse-dialing phone, wait five seconds or longer before re-
entering the 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.
VERSA-LINK ATX-250
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-dialFAX tones
and device codes. If the phone is not answered in 5 rings
(this number is selectable - see section 6.2 ) , your ATX-
250 will assume that the office is unattended, and that this
call and all future calls should go to the FAX.
Your ATX-250 will immediately begin ringing this call to the
FAX. (If your FAX has adjustable ring selection, set it to
answer on the earliest possible ring).
At this time, your ATX-250 begins to operate in NIGHT
FUNCTION. Now, incoming calls will ring your telephone
system only 2 times (this number is selectable - see
section 6.2 ), 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-250 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, 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
(b) You DO NOT have an answering machine on the same
incoming line as your FAX or MODEM.
See section 6.2 to activate CALL OPTI-MIZER.
VERSA-LINK ATX-250 12

OPERATION
4.3 SUMMARY OF OPERATION
Your ATX-250 will answer incoming calls on the first ring and
produce a simulated
ringback tone to the caller. Your ATX 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-250 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-250 will begin to ring the
equipment attached to DEVICE 1. Once connected, your
ATX-250 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. A busy signal is conveniently provided to all
non-selected devices.
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.
If the caller is dialing long distance, charges begin when your
ATX-250 answers incoming calls.
RINGING DEVICES
When your ATX-250 is ringing a device, it will attempt eight
rings to that device. If the selected device does not answer
within this period, your ATX-250 will disconnect the call and
restore all devices to their original condition.
TRANSFER DEFEAT
Dialing “80” on an inbound call will cause your ATX-250 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 accidently transferring your call.
VERSA-LINK ATX-250 13

INSTALLATION
The following section covers installation
of your Versa-Link ATX-250 in various
applications.
Your “ATX-250 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-250 shipping carton should
contain the following equipment:
- Your Versa-Link ATX-250
- An AC wall transformer with cord
- One modular telephone cable
Plug the 12 Volt 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-250. The
LED indicator on the front
of your ATX-250 should now be lit,
showing that power is on and the
ATX-250 is operating.
5.2 CONNECTING TO
THE PHONE LINE LINE LINE
WHAT LINE DO I LINE DO IUSE?
Locate and identify the telephone line to
which you plan to attach your ATX-250. If
you are using a multi-line telephone
system with rollover, use the last line in
the rollover sequence.
WHERE DO I CONNECT MY ATX-250?
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-250. You may need
to install RJ-11 jacks to facilitate
installation of your ATX-250.
IMPORTANT: One function of your
ATX
250 is to receive incoming calls and then
distribute them to the proper equipment.
For this reason it is VERY important that
your
ATX-250 be installed ahead of all
existing telephone extensions and
equipment.
tl,
LIW
cdc:,
Attach the incoming telephone line to the
LINE connector on the back of your
ATX-250. The
Am-250 should now be
the only device connected to this
telephone line.
5.3 RE-CONNECTING
YOUR TELEPHONE
SYSTEM
If you are using this line for voice
communication, you will need to
reconnect your telephone system
THROUGH THE ATX-250. First, you will
want to determine what type of phone
system you have.
VERSA-LINK ATX-250
14

INSTALLATION
5.3.1 Single Line
Telephones
Attach your telephone system to the
DEVICE 1 connector on the back of your
ATX-250. If you have only one phone with
no extensions, you can connect the
phone by plugging it into the DEVICE 1
connector on your ATX-250. If you have
extensions, attach the
DEVICE 1
connector to one of the extension jacks.
This will re-connect all the extensions.
5.3.2 Multi-line
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-250.
NOTE: Your ATX-250 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-250.
5.3.3PBX (Private
Branch Exchange)
Your ATX-250 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-250
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 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.
VERSA-LINK ATX-250 15

How you attach your data equipment
depends entirely on what you want your
system to do. Some of the most popular
applications are listed below:
5.4.1 Adding FAX to a
VoiceLine
When adding FAX to a voice line, attach
your FAX to the DEVICE 2 connector on
the back of your ATX-250. See your
installation manual for details.
You should enable auto FAX tone
detection. Configuration switch 6 should
be set to the “up” position. This is the
factory setting.
If necessary, change the configuration
switch on the back of your ATX-250.
Unplug the ATX-250 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-250 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-
250 for about 2 seconds and re-connect
it to activate the new switch settings.
5.4.3 Allowing Two 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-250. Attach your
other data device to the DEVICE 2
connector.
VERSA-LINK ATX-250 16

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-250. Attach the other data device to
the DEVICE 2 connector.
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-
250 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.”
5.5 CONFIGURINGTHE
ATX-250 TO YOUR
APPLICATION
Depending on your application, you may
want to change the factory settings of the
configuration switches or change the
device selection codes.
For a detailed description of all the operational
features, and step-by-step information on
how to select them, see section 6, USER
SELECTABLE FEATURES.
5.6GENERAL RULES OF
INSTALLATION
When installing your ATX-250 there are
three general principles to keep in mind:
5.6.1 Your ATX-250 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-250 on this line. All extensions and
data devices must be connected to one
of the DEVICE ports on the back of your
ATX-250.
VERSA-LINK ATX-250 17

INSTALLATION
For example, if you connect your ATX-
250 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-250
cannot prevent an extension phone from
being lifted and interrupting a FAX call.
For the same reason, party lines and off-
premise extensions (OPX), including
answering services located away from
your building, are not compatible with
your ATX-250. Do not install an ATX-250
if you are on a party line or have an OPX.
5.6.2
Your ATX-250 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-
250 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-250 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 or 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 in-
stall your ATX-250 from another location,
and listen to determine if the person who
answers can dial touch-tones.
Pulse-dialing telephone equipment and
some key systems do not generate the
* or # signals. You can overcome this
limitation by changing the ATX-250
device selection codes to new codes that
do not contain * or # . See section 6.1
to change device selection codes.
On a few key systems, dialing * # will
unlock the key pad to once aain 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
pressin
the “FLASH” key, and then
dialing
* 2 To keep from hanging up
B
the caller, activate the “Protected Hook
Flash” feature. See section 6.3.
