4. Using the Lineshare Pro

4.1 Special Operating Notes

Before operating the Lineshare Pro, be sure that you understand the following information about the telephone equipment that is used with the Lineshare Pro (if you use a fax or fax modem card).

Fax CNG tones: Most fax machines send audible beep tones called CNG (CalliNG) tones. Once a fax machine has dialed the destination fax machine’s number, it generates this tone while waiting for the receiving fax to answer. This tone is a distinct beep that repeats every three (3) seconds. Most fax machines 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. However, not all fax machines transmit this signal when they place a call. For best results with automatic switching to a fax machine, callers should have your fax number programmed into their fax machine’s speed-dial memory.

Computer modems: Unlike fax calls, inbound computer calls do not produce any tones; they remain silent until another modem answers the call.

The Lineshare Pro works best when calls from modem-type devices have the ability to identify themselves with an identifying tone.

One device that identifies a modem-type device with a single- frequency tone is called the Lineshare Master (FX155A). The Lineshare Master can produce eight different single-frequency tones that allow the Lineshare Pro to route calls to multiple modem-type devices connected to a single phone line.

4.2 Lineshare Pro Call Routing

When the Lineshare Pro answers a call, it listens for specific pre- programmed tones and automatically routes the call to the correct port. If a tone is not present, the call is routed to the first port in the Cascade Port Order (depending on your configuration). You can then answer the phone, decide the origin of the call, and route the call manually if necessary.
