Important Notes (return to top)
According to standard industry practice, surge protection is recommended for use with all electronic devices. A surge suppressor and/or line conditioning should be used on the input power supply, as well as the connected telephone line.

Call Waiting: Fax machine and modem transmissions could be disrupted by the call waiting beep tone.

Call Forwarding: If Call Forwarding is activated, the CS 300 cannot process calls on that line.We recommend that you disconnect service for Call Forwarding.

Phone Company Voice Mail: This service is not compatible with the CS 300, however, stand-alone voice mail systems work well with the CS 300.

Introduction to the CS 300 (return to top)

Thank you for purchasing the CS 300. Data communications is becoming increasingly popular, and the CS 300 allows you to take advantage of this technology.

The CS 300 is a state-of-the-art Telephone Line Sharing device which eliminates the extra dedicated telephone lines used to operate a fax, modem, or other telephone device.

The CS 300 quickly directs incoming telephone calls to one of three appropriate destinations, typically a computer modem (or fax/modem) or facsimile machine, as well as a telephone and answering machine, or any other telephone device that responds to a standard phone company ring signal.

Please read through the rest of this guide to learn how to properly install and operate the CS 300.
Unpacking the CS 300 (return to top)

When you open the CS 300 box for the first time, inspect the contents. In the box you should find the following items:

If any of these items are missing or damaged, contact the dealer where you purchased the unit, or call Customer Service at the number listed in "Two year limited warranty/Service Information."

Installing the CS 300 (return to top)

The CS 300 is a single line device that can be installed on any type of 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.

Ports on the CS 300 (return to top)
The rear panel of the CS 300 includes four (4) modular ports and a power input port, as shown:

CS300

1. Connect a single telephone line from a standard telephone (wall) jack to this port. The CS 300 will route all calls to the TAD and PHONE ports simultaneously.
2. Connect your Telephone Answering Device (TAD) or integrated phone/answering machine to this port. The CS 300 will route all calls to the TAD and PHONE ports simultaneously.
4. The fax machine must be connected to the FAX/MODEM port to enable the CS 300 to automatically transfer a fax call with a fax CalliNG (CNG) tone to the fax machine. A computer modem or fax/modem can also connect to this port in lieu of a fax machine.
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.

(See "Special operating notes" for an explanation of CNG tones.)
Placing the CS 300 (return to top)

The CS 300 can be placed on either a flat surface, or mounted on a wall (connectors not included) with the connected telephone line cords above or below the unit.

In this section, there are special operating notes you should read before operating the CS 300. The section following these operating notes provides an overview of the CS 300 standard operations and instructions for answering and transferring your incoming calls.

CS 300 Operator's Guide

Special operating notes (return to top)

Before operating the CS 300, be sure that you understand the following information concerning the telephone equipment that is used with the CS 300.

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.

 CS 300 Operator's Guide

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.

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

When you or your answering machine answer a call, you may hear a CNG tone; if the tone is present, the CS 300 will automatically route the call to the FAX/MODEM port.

Standard operations (return to top)

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 300 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 300 listens for the following signals:

CS 300 Operator's Guide 

a CNG tone  (Beep)

CS 300 Operator's Guide 

an access code for the FAX/MODEM port
CS 300 Operator's Guide

If the CS 300 detects any of these signals, it transfers the call to the FAX/MODEM port.

If the CS 300 transfers an unanswered call to the FAX/MODEM port, it will automatically reduce the number of rings to your telephones to 3 rings to ensure optimum connect time.

The CS 300 will reset the ring count to 6 rings after 5 minutes of inactivity on the FAX/MODEM port. You can also manually reset the CS 300 to 6 rings by performing any of the following steps:

CS 300 Operator's Guide 

Lift the receiver of any phone device on the line connected to the CS 300 and hang it up.

CS 300 Operator's Guide 

Answer a call from any phone before the call is transferred to the FAX/MODEM port.

CS 300 Operator's Guide 

Place an outbound call from any phone connected on the line connected to the CS 300.

Answering incoming calls (return to top)

CS 300 Operator's Guide

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  #99 from a tone phone or 3  from a rotary/pulse dialing phone.

2.

If a caller verbally requests to be connected to the fax or computer modem, you can manually transfer the call by entering the FAX/MODEM port access code.

3.

If you hear a CNG tone or an access code for the FAX/MODEM port, after answering a call, remain on the line until the fax or modem answers, or manually transfer the call by entering the FAX/MODEM port access code. In either case, you must remain on the line until your fax or computer modem answers. The CS 300 disconnects the PHONE and TAD ports when the fax or modem answers the call.

NOTE: You cannot answer a voice call from a phone connected to the fax machine or computer modem.
Answering calls with an answering machine (return to top)

CS 300 Operator's Guide

If your answering machine answers a call from the TAD port, the caller can perform the following tasks:

CS 300 Operator's Guide 

record a voice message on the answering machine and/or

CS 300 Operator's Guide 

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 #99 on your tone phone, or leave a message at the tone. "

* You should leave a four (4) second silent period at the beginning of the outgoing message you use on your answering machine.

To accommodate auto-dial faxes that do not produce CNG tones, the CS 300 monitors the line 20 seconds after a call is answered on the TAD port. If the CS 300 determines that a caller is not leaving a message on your answering machine during the next 5 second period, the CS 300 transfers the call to the FAX/MODEM port.

To accommodate these timing parameters, your outgoing message should be no less than 10 seconds, and no longer than 15 seconds in length.

NOTE: Callers cannot transfer a call to the FAX/MODEM port from a pulse dialing fax.
NOTE: Single cassette answering machines are not recommended for use with the CS 300 due to timing limitations of these types of machines.

NOTE: If calls are being transferred to the FAX/MODEM port when a caller is leaving a message, you may want to instruct the caller (in your answering machine announcement message) to press the * key from a tone phone to leave an uninterrupted message.

Retrieving answering machine messages from a remote location (return to top)

To disable the CS 300 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 * * on your tone phone.

1.

Follow the remote retrieval procedures for your answering machine.

2.

After retrieving your messages, hang up. The CS 300 resets for the next call.

Troubleshooting (return to top)

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

The CS 300 is a semi-automatic line sharing device, therefore all calls are routed first to the TAD and PHONE ports. When a device connected to one of these ports answers a call, the CS 300 then listens for fax tones to transfer the call. If you answer a call and hear a fax tone, keep the phone off-hook until your fax answers and then hang up.

Why can't I receive faxes when I'm away from the CS 300? (When an answering machine is connected to the CS 300.)

Check the following settings and procedures:

1. 

Instruct callers to press #99 to send a fax.

2. 

Make sure you left 4 seconds of recorded silence 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 #99 on your tone phone, and then hang up.

Why don't fax calls transfer to the fax when my answering machine answers a call?

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 300, 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 300, what should I do?

Check all of the phone line connections and repair or replace any damaged cables.

CS 300 Operator's Guide
Registration information

The CS 300 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 300 may not be connected to a party line or coin line telephone network. If the CS 300 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 300 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 300, 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.
