QUESTIONS AND ANSWERS
Here are some common questions and answers about how your AFX-300 operates.
What is line sharing?
Line sharing lets you use one telephone line for more than one purpose. For example, you can use one telephone line for reg- ular calls, fax or modem transmissions, or calls to your an- swering machine. Line sharing eliminates the need for additional phone lines.
How does my AFX-300 know its a fax call?
Unless you use the first number distinctive ringing feature, the fax machine must wait for you, the TAD, or the AFX-300 to an- swer the phone before it knows whether or not the call is a fax. When a fax machine calls, it repeatedly sounds a 1/2-second tone followed by a 3-second pause on the phone line (fax alert tone) until another fax machine responds. The AFX-300 lis- tens for these tones.
How does my AFX-300 know its a data modem call?
Unless you use the second number distinctive ringing feature, the data modem must wait for you, the TAD, or the AFX-300 to answer the phone before it knows whether or not the call is a data modem. When a data modem calls, it makes no sounds at all until your data modem sends it a signal to begin the transmission. The AFX-300 listens for at least 20 seconds of silence (no fax alert tones or touch-tone commands), then au- tomatically transfers the call to your data modem.
