1 CS 5500 Operator’s Guide
Installing the CS 5500
The CS 5500 is a single line telephone device that can be
installed on any type of modular or non-modular system that
consists of one or more lines, with one or more phones. A
modular system consists of phone cables that can be connected
and disconnected from a telephone device.
A non-modular system consists of cables that are hard-wired to
the telephone device and cannot be disconnected from the
equipment.
A telephone installer may be required to install the CS 5500 on
a non-modular system.
NOTE: Many offices have a KSU or PBX phone system. The
CS 5500 works with either of these systems. Simply follow the
appropriate installation instructions provided in "Installation on
a telephone system."
Ports on the CS 5500
The rear panel of the CS 5500 includes four (4) modular ports and a power input port, as shown:
Connect a single telephone line from a standard telephone
(wall) jack to this port.
Connect your fax machine to the FAX/MODEM port. A
computer modem or fax/modem can also connect to this
port in lieu of a fax machine.
Connect a single line Telephone Answering Device

(TAD) or integrated phone/answering machine to this
port.
Depending on the installation, a single line phone, an
integrated phone/answering machine, multiple phones, or
a telephone system (KSU or PBX) can be connected to
this port
The CS 5500 will transfer all voice calls to the TAD and
PHONE ports simultaneously.
Placing the CS 5500
The CS 5500 can be placed on either a flat surface, or mounted on a wall
with the connected telephone line cords above or below the unit. To
mount on a wall, follow these steps:
1. Mark the positions for 2 mounting screws (not supplied) on the wall.
The positions should be 3 1/4" apart (vertically). Drill the 2 holes,
then thread the screws into the wall. The screws should extend 3/16".
Do not over tighten the screws.
2. Align the keyholes on the back of the CS 5500 with the 2 screws, then
push in and press down to secure it to the wall.
You can place the telephone line cords through the line guides on the

Using the CS 5500
In this section, there are special operating notes you should read before operating
the CS 5500. This section follows an overview of the CS 5500 standard operations
and instructions for answering and transferring your incoming calls.
CS 5500 Operator’s Guide 4
Standard operation
The CS 5500 has 2 modes of operation, Automatic mode and Semi-Automatic mode. The factory setting is in the Automatic mode.

Automatic mode operation
When a call comes in, the CS 5500 answers the call on the first
ring (second ring if Caller ID is turned ON). During the next
four seconds the CS 5500 listens for the following signals:
a CNG tone (Beep)
an access code for the FAX/MODEM port #11
If the CS 5500 detects any of these signals, it transfers the call
to the FAX/MODEM port.
After 4 seconds, the call will be transferred to the PHONE and
TAD ports if tones are not detected.
If the CS 5500 transfers an unanswered call to the
FAX/MODEM port, it will automatically reduce the number of
rings to the telephones connected to the TAD or PHONE ports
to 2 rings to ensure optimum connect time.
Semi-Automatic mode operation
When a call comes in, all the phones begin to ring (including
extension phones, and phones connected to the PHONE and
TAD ports). The CS 5500 allows 6 rings to the telephones
before it automatically transfers the call to the FAX/MODEM
port. If you or your answering machine answer the call before
this transfer occurs, the CS 5500 listens for the following
signals:
a CNG tone (Beep)
an access code for the FAX/MODEM port #11
If the CS 5500 detects any of these signals, it transfers the call
to the FAX/MODEM port.
If the CS 5500 transfers an unanswered call to the
FAX/MODEM port, it will automatically reduce the number of
rings to your telephones to 2 rings to ensure optimum connect
time.
The CS 5500 will reset the ring count to 6 rings after 10 minutes of inactivity on the FAX/MODEM port. You can also manually
reset the CS 5500 to 6 rings by performing any of the following steps:
zLift the receiver of any phone device on the line connected to the CS 5500 and hang it up.
zAnswer a call from any phone before the call is transferred to the FAX/MODEM port.
zPlace an outbound call from any phone connected on the line connected to the CS 5500.
The default operating mode for the CS 5500 is the Automatic mode.
To return the CS 5500 to the Automatic mode, perform the
following steps:
1. Take the phone in the PHONE port off-hook
2. Press # * 210 * (three beeps) 402 * (three beeps) *
3. Hang up the phone
To operate the CS 5500 in the Semi-Automatic mode, perform
the following steps:
1. Take the phone in the PHONE port off-hook
2. Press # * 211 * (three beeps) 401 * (three beeps) *
3. Hang up the phone
NOTE: Extension phones not connected directly to the CS 5500 will ring only 1 time if the CS 5500 is in the Automatic mode
(2 times if Caller ID is turned ON). In the Semi-Automatic mode, all phones will ring up to 6 times (factory setting).
Special operating notes
Before operating the CS 5500, be sure that you understand the
following information concerning the telephone equipment that
is used with the CS 5500.
Fax CNG tones: Most faxes send audible beep tones called
CNG (CalliNG) tones. This tone is a distinct beep that repeats
every three (3) seconds. Once a fax has dialed the destination
fax number, it generates this tone while waiting for the
receiving fax to answer.
For best results, callers should have your fax number
programmed into their fax machine's "speed-dial" memory.
Beep Beep Beep
Not all faxes transmit this tone when they place a call. Most,
but not all faxes produce this tone through their auto-dial
feature, speed-dial memory position, or by the operator
pressing the fax machine's start button after the number is
dialed.

5 CS 5500 Operator’s Guide
Answering incoming calls
You can answer incoming calls from an extension phone or from a phone device connected to the TAD
or PHONE port. You can then conduct the call normally, for as long as you like.
1. If, after answering a call, you hear silence on the line, the call
is likely coming from a fax that does not produce a CNG
tone. Simply transfer the call to the FAX/MODEM port
by entering #11 from a tone phone or 3from a rotary/pulse
dialing phone.
2. To transfer a voice call to the FAX/MODEM port, press #11
from a tone phone or 3from a rotary/pulse dialing phone.
3. In the Semi-Automatic mode, if you hear a CNG tone or an
access code for the FAX/MODEM port, after answering a
call, simply hang up the phone.
NOTE: If the CS 5500 is in the Automatic mode, you cannot perform rotary/pulse dialing transfers from extension phones not
connected to the CS 5500.
Answering calls with an answering machine
If your answering machine answers a call from the TAD port, the caller can perform the following
tasks:
z
record a voice message on the answering machine and/or
z
transfer their call to the FAX/MODEM port
We recommend that you use your answering machine announcement message to provide callers with
instructions for transferring their calls.
Following is a sample announcement message that you may
wish to use:
" * Hello, this is ________. If you wish to send a fax, press
#11 on your tone phone, or leave a message at the tone. "
* If the CS 5500 is in the Semi-Automatic mode, you should
leave a four (4) second silent period at the beginning of the
outgoing message you use on your answering machine.
NOTE: Callers cannot transfer a call to the FAX/MODEM port
from a pulse dialing fax.
NOTE: Fax calls that do not produce a CNG tone will transfer to your answering machine. To allow the CS 5500 to transfer these
calls to the FAX/MODEM port, program the CS 5500 as follows.
To turn FAX transfer ON, perform the following steps:
1. Take the phone in the PHONE port off-hook
2. Press # * 11 * (three beeps) *
3. Hang up the phone
To turn FAX transfer OFF, perform the following steps:
1. Take the phone in the PHONE port off-hook
2. Press # * 01 * (three beeps) *
3. Hang up the phone
With this feature turned ON, the CS 5500 will monitor the line
for 30 seconds after the answering machine answers a call. If
the answering machine disconnects from the call during this
time, the CS 5500 automatically transfers the call to the
FAX/MODEM port.
To accommodate these timing parameters, your outgoing
message should be no less than 15 seconds, and no longer than
20 seconds in length. (Single cassette answering machines are
not recommended for use with this feature due to timing
limitations of these types of machines.)

CS 5500 Operator’s Guide 6
Retrieving answering machine messages from a remote location
To disable the CS 5500 and retrieve your answering machine
messages, follow these steps:
1. Dial your phone number and wait for the answering machine
to answer the call.
2. After your answering machine answers the call, press 5on
your tone phone.
3. Follow the remote retrieval procedures for your answering
machine.
4. After retrieving your messages, hang up. The
CS 5500 resets for the next call.
Placing an outbound call
You can place an outbound call from the PHONE port, unless
another port is in use. If another port is in use, you will hear a
busy signal when you attempt to place a call. If the line is clear
when the calling device goes off-hook, you receive a dial tone
and can place the call normally.
During an outbound call, you can also receive a transmission
from someone that is ready to transmit.
To transfer this transmission to the FAX/MODEM port, any
time during a conversation, press #11 from a tone phone,
or 3from a rotary/pulse dialing phone.
Rotary/pulse transfers are not possible until 20 seconds after
dialing the last digit of the phone number.
(Picking up an extension phone not connected to the TAD or
PHONE port during a data or fax transmission may interrupt the
call.)
Receiving a computer call
Unlike a fax call, inbound computer calls do not produce identifying tones; they remain silent until another
modem answers the call. To receive a computer call to the FAX/MODEM port, instruct the caller to use
one of the following methods. (In this example, we use a modem.)
Dialing the receiving computer through the originating (calling) computer
To have the calling modem automatically "over dial" the
FAX/MODEM port access code and access the modem
connected to the CS 5500, the caller must take into
consideration whether the call is local or long distance.
For remote access to the FAX/MODEM port on the
CS 5500, instruct the caller to use the following dialing string
in the modem's software:
phone number,#11,# 11,# 11,# 11 (for Automatic mode)
phone number,,,# 11,# 11,# 11,# 11 (for Semi-Automatic)
For long distance remote access to the FAX/MODEM port of
The calling modem picks up its phone line and dials the phone
number. The comma (,) tells the modem to wait about two
(2) seconds and then repeatedly over dial the access code.
In the Automatic mode the CS 5500 will answer a call, detect
the tones and transfer the call to the FAX/MODEM port.
In the Semi-Automatic mode, you or your answering machine
will answer the call, then the CS 5500 will detect the tones and
transfer the call to the FAX/MODEM port.
NOTE: Not all modem comma (,) commands delay dialing for
a 2 second interval. See your modem Operator's Guide and

the CS 5500, instruct the caller to use the following dialing
string in the modem's software:
1 + phone number,,,# 11,# 11,# 11,# 11(for Automatic mode)
1 + phone number,,,,,# 11,# 11,# 11,# 11 (for Semi-
Automatic)
adjust the number of commas you use accordingly.
NOTE: In the Semi-Automatic mode, the commas entered
before the #11 are set to your answering machine's 2 ring
answer. Use 3 additional commas for each ring that your
answering machine is set to answer above 2 rings.
7 CS 5500 Operator’s Guide
Distinctive Ring service compatibility
When you add a second or third phone number to your single
line, the CS 5500 works smoothly to process calls without
depending on access codes or transfer tones.
The phone company's Distinctive Ring service is offered in
most areas across the U.S. Phone companies offer this service
under various names, check with your local phone company for
details.
The CS 5500 will process the additional phone numbers (ring
styles) as follows:
standard ring - - - - PHONE and TAD ports
two-burst ring - - - - FAX/MODEM port
The factory setting for Distinctive Ring detection is OFF.
To turn Distinctive Ring detection ON, perform the following
steps:
1. Take the phone in the PHONE port off-hook
2. For line 1, press # * 114 * (three beeps) *
3. Hang up the phone
To turn Distinctive Ring detection OFF, perform the following
steps:
1. Take the phone in the PHONE port off-hook
2. For line 1, press # * 014 * (three beeps) *
3. Hang up the phone
Contact Customer Service for more information regarding operation with the Distinctive Ring service.
Remote Message Notification
The CS 5500 can automatically send a special tone message to
any desired telephone number - local or long distance every
time you receive a voice message, fax document or data
transmission.
One application using Remote Message Notification would
allow the CS 5500 to notify you when a message is received on
your answering machine.
During the notification call from the CS 5500, you can retrieve
the message from your answering machine (if the answering
machine is able to play back messages remotely).
NOTE: The Remote Message Notification is programmable
ON/OFF with various settings (default OFF). Contact Customer
Service for more information.
Features of the CS 5500 are programmable. Programming options are available upon request by

CS 5500 Operator’s Guide 8
Troubleshooting
Why are fax calls being transferred to my telephone and/or
answering machine?
If the CS 5500 is in the Semi-Automatic mode, it will wait
for you or your answering machine to answer a call before
it transfers calls to the FAX/MODEM port.
If the CS 5500 is in the Automatic mode, these are calls
that did not produce transfer tones.
See "Answering incoming calls" for transferring
instructions.
Why can't I receive faxes when I'm away from the CS 5500?
(When an answering machine is connected to the CS 5500.)
Check the following settings and procedures:
1. Instruct callers to press #11 to send a fax.
2. Make sure you left 4 seconds of recorded silence (only
when using the Semi-Automatic mode) before
recording the outgoing message you use on your
answering machine.
3. Set your fax to answer on 1 ring.
4. Set your answering machine to answer on 2 rings.
Why don't fax calls transfer to the fax when I answer the
phone?
Some fax machines do not produce fax tones, therefore,
when you receive this type of call, press #11 on your tone
phone, and then hang up.
Why don't fax calls transfer to the fax when my answering
machine answers a call (CS 5500 is in the Semi-Automatic
mode)?
You may not have the 4 second silence at the beginning of
your answering machine announcement message. If you
do, contact Customer Service for more information.
The LED doesn't light on the CS 5500, what should I do?
1. Check your power connection. If power is connected
properly, make sure that you are using a 12 volt AC
power adapter.
2. Verify that the phone line is properly connected to the
LINE IN port.
I don't have dial tone with the phone(s) connected to the
CS 5500, what should I do?
Check all of the phone line connections and repair or
replace any damaged cables.
