CS8500-t Operator’s Guide 2

Introduction to the CS8500-t

Thank you for purchasing the CS8500-t. This product was designed for environments that have hearing­impaired and non hearing-impaired users sharing the same phone line that want to save money by
avoiding multiple dedicated telephone line charges. The CS8500-t allows a TTY/TDD, fax, telephone and
answering machine to share one single telephone line.

The CS8500-t quickly directs incoming telephone calls to one of three appropriate destinations, typically a
TTY/TDD, facsimile machine or fax/modem, as well as a telephone and answering machine, or any other
telephone device that responds to a standard ring signal.

Listed below are examples of various telephone activated devices that can be connected to the CS8500-t:

Basic Operation

The CS8500-t is flexible and easy to use. When a call is received by the CS8500-t, the call is answered
with a voice announcement for voice callers instructing them to hold while the call is being transferred.

After the CS 8500-t answers a call, it will give a voice announcement to the caller, “Please hold through
the tones, your call is being transferred.”

Next, the CS 8500-t will send the calling TTY a message that reads “ TYPE GA TO CONNECT.”

If the CS 8500-t does not detect a TTY tone from a calling TTY, the call will be transferred to the TAD
and PHONE ports on the CS 8500-t.

If the caller types GA after the TTY message, the CS 8500-t will send the message “PLEASE WAIT” to
the calling TTY and then transfers the call to the TTY port on the CS 8500-t.

The ring count to the TTY port is set to 25 rings.

Fax calls are detected by the CNG tone (CalliNG) and sent to the FAX port automatically. Non-CNG fax
calls are sent to ANS. MACHINE and Phone ports.

3 CS8500-t Operator’s Guid

The CS8500-t has over 30 programmable features that allow the user to customize its operation. In
addition, the CS8500-t is compatible with:

1. Call Waiting

2. Distinctive Ring

3. Caller ID

4. Voice Mail (when used in conjunction with Distinctive Ring). See Voice Mail and Distinctive

Ring setup

Installing the CS8500-t

The CS8500-t is a single line 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 cords
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 CS8500-t on a non-modular system.
NOTE: Many offices have a KSU or PBX phone system. The CS8500-t works with either of these
systems. Simply follow the appropriate installation instructions provided in "Installation on a KSU/PBX
Installation."

Ports on the CS8500-t

The rear panel of the CS8500-t includes five
(5) modular ports and a power input port, as
shown:

1. Connect the provided (2-wire) modular line cord from a standard telephone (wall) jack to this port.

2. Connect your single line telephone answering machine or integrated phone/answering machine to

the ANS. MACHINE port. The CS8500-t will transfer all voice calls to the ANS. MACHINE and
PHONE ports simultaneously.

3. 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 CS8500-t
will transfer all voice calls to the ANS. MACHINE and PHONE ports simultaneously.

4. Connect your fax machine to the FAX port.

5. Connect your TTY/TDD device to the TTY/TDD port to enable the CS8500-t to transfer a

TTY/TDD call with the appropriate tones or transfer codes.

CS8500-t Operator’s Guide 4

The CS8500-t 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:

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, and then thread the screws into the wall.
The screws should extend 3/16". Do not over tighten the
screws.

Align the keyholes on the back of the CS8500-t 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 back of the CS8500-t to reduce tangling.

Connecting the CS8500-t

This section explains how to install the CS8500-t in most phone configurations that appear in a home or
office. You can install the CS8500-t into one of the following phone configurations:

Y 1 or 2-line telephones (see pages 6 - 9)

0

procedures if you have a mini-telephone system in your home or small office. For the CS8500-t to operate
properly, it must be "in front" of the telephone system. In other words, it must connect directly to the
incoming telephone line. Connect the other equipment as previously shown.

NOTE: All equipment on that line (KSU/PBX, TTY/TDD, FAX) must be connected directly to the
CS8500-t.

CAUTION: You should be familiar with telephone wiring to complete this installation. If you have any

questions or are not confident that you can complete this installation procedure, contact a professional
installer. For further help, contact Customer Service at (TTY/TDD) 1-888-323-0714 or 303-873-7477,
(VOICE) 1-800-288-6794, M-F 7-5 MST., or (FAX) 303-792-0855.

Do not plug the CS8500-t into a telephone system phone jack. You may damage your telephone
system.

Using the CS8500-t

In this section, there are special operating notes you should read before operating the CS8500-t. The
section following these Operating Notes provides an overview of the CS8500-t standard operations and
instructions for answering and transferring your incoming calls.

CS8500-t Operator’s Guide 1

Special Operating Notes

Before operating the CS8500-t, be sure that you understand the following information concerning the
telephone equipment that is used with the CS8500-t.

FAX CNG Tone: Most faxes send an audible beep tone called CNG (CalliNG) tone. 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.

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.

For best results, callers should have your fax number programmed into their fax machine's "speed-dial"
memory.

Single Line Operation

Placing an Outbound Call Using the CS8500-t

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 will hear 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 your FAX port, any time during a conversation, press
from a touch-tone phone.

To transfer this transmission to your TTY/TDD port, any time during a conversation, press

from a touch-tone phone.

Picking up an extension phone not connected to the ANS. MACHINE or PHONE port during a data or fax
transmission may interrupt the call.

CS8500-t Operator’s Guide 1

Answering Incoming Calls

When the CS8500-t answers a call and does not detect any signal, the call will be routed to the ANS.
MACHINE or PHONE port.

NOTE: Extension phones not connected directly to the CS8500-t will ring only 1 time when the CS8500-t
answers the call (2 times if Caller ID is turned ON).

You can answer incoming calls from an extension phone or from a phone device connected to the ANS.
MACHINE 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 port by entering

a touch-tone phone.

2. To transfer a manual fax call to the FAX port, press from a touch-tone phone.

3. To transfer calls to the TTY/TDD port, press

from a touch-tone phone.

Answering Calls with an Answering Machine

If using an answering machine, the caller can leave a message and/or transfer their call to the FAX or
TTY/TDD 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 on your touch-tone phone, or
leave a message at the tone. If you wish to reach the TTY, please call from your TTY machine.

NOTE: Callers cannot transfer a call to the FAX port from a pulse dialing phone.

NOTE: FAX calls that do not produce a CNG tone will transfer to your answering machine. To allow the

CS8500-t to transfer these calls to the FAX port, program the CS8500-t as follows.

Why are fax calls being transferred to my telephone and/or answering machine?

See "Answering incoming calls" for transferring instructions.

Why can't I receive faxes when I'm away from the CS8500-t (when an answering machine is
connected to the CS8500-t)?

Check the following settings and procedures:

Instruct callers to press

to send a fax.

Set your fax to answer on the lowest number of rings.

Set your answering machine to answer on 2 - 4 rings.

The LED doesn't light on the CS8500-t, what should I do?

Check your power connection.

If power is connected properly, make sure that you are using a 12 volt AC
power adapter.

Verify that the phone line is properly connected to the LINE IN port.

19 CS8500-t Operator’s Guid

Registration information

The CS 8500-t has been registered with the Federal Communications Commission (FCC). It meets FCC requirements and may be connected
directly to your telephone line. 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. If requested, this information must be provided to the telephone company. Use the
REN to help determine the maximum number of devices you can connect to your telephone without eliminating their ability to ring when your
number is called. In many areas, the sum of the RENs of all devices connected to one line should not exceed 5.0. To determine how many
devices you can connect to your line, contact your local telephone company to find out the maximum REN for your area.

The CS 8500-t may not be connected to a party line or coin line telephone network. If the CS 8500-t does not function properly, disconnect the
unit. Follow the instructions provided in the section "Two year limited warranty" to obtain the necessary repair service.

If the CS 8500-t causes harm to the network, the telephone company may discontinue your service temporarily. If possible, they will notify you
in advance. But if advance notice is not practical, the telephone company will notify you as soon as possible. Also, you will be advised of your
right to file a complaint with the FCC if you believe it is necessary.

The telephone company may make changes in the telephone network. Should these changes affect the CS 8500-t, the telephone company must
notify you, in writing, to enable you to maintain uninterrupted service.

If you need to order a modular jack from the telephone company, request either a USOCRJ11C or a USOCRJ13C.
