In this section, there are special operating notes you should read before operating the CS 350. The section following these operating notes provides an overview of the CS 350 standard operations and instructions for answering and transferring your incoming calls.

Special operating notes (return to top)

Before operating the CS 350, be sure that you understand the following information concerning the telephone equipment that is used with the CS 350.

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.

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 350 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 350 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 350 listens for the following signals:

 

a CNG tone  (Beep)

  

an access code for the FAX/MODEM port

If the CS 350 detects any of these signals, it transfers the call to the FAX/MODEM port.

If the CS 350 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 350 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 350 to 6 rings by performing any of the following steps:

 

Lift the receiver of any phone device on the line connected to the CS 350 and hang it up.

 

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

 

Place an outbound call from any phone connected on the line connected to the CS 350.
Answering incoming calls (return to top)

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 350 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)

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

 

record a voice message on the answering machine and/or

 

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 350 monitors the line 20 seconds after a call is answered on the TAD port. If the CS 350 determines that a caller is not leaving a message on your answering machine during the next 5 second period, the CS 350 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 350 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 3500 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 350 resets for the next call.
