 Introduction (return to top)

The ComSwitch 3.0 provides the two most useful features you’ll ever add to your telephone line, all in one device.

  1. Switches: The CS 3.0 quickly directs telephone calls to the appropriate device on a single phone line. These devices are usually an answering machine, telephone, fax and a modem or fax modem. Any other telephone device that responds to a standard phone company ring signal may be connected to the CS 3.0

  2. Alerts: When you’re online with your computer, the CS 3.0 will ALERT you to incoming calls, allowing you to briefly take the call without losing your online connection. (Requires Call Waiting or Call Waiting ID from your phone company.) 
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 Forwarding: If Call Forwarding is activated, the 
CS 3.0 cannot process calls for the forwarded number. If you use Distinctive Ring Service, the CS 3.0 can process calls on those numbers that have not been forwarded.

Phone Company Voice Mail: This service is compatible with the CS 3.0 if used in conjunction with the phone company’s Distinctive Ring service (service activation required).

 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.

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.
Place the CS 3.0 at least 2 feet away from other electronic equipment to avoid potential interference.
