Working with your answering machine
Q:People have complained that they call my fax machine and hear my answering machine’s message, but are cut off before they can send a fax. What happened?
A:Any remote fax machine attempting to send a fax must “hear” responding fax tones within 40 seconds after the person at that machine presses the start key. That 40 seconds includes getting the dial tone, dialling the number, “listening” to the pause before the ringing starts and the remote fax machine answering the ring. Only after that time does your message play.
That’s why we urge you to create a short outgoing message. The shorter the waiting period, the more likely it is that the remote fax machine will proceed with the transmission. Please create an outgoing message on your answering machine that’s no longer than 10 seconds (see page 1.20 for a suggestion).
Polling
Q:What’s the purpose of polling?
A:Polling lets you automatically “pull” a document which is set in another fax machine. You can poll whenever you need to retrieve information and don’t want the source to pay for the phone call. With polling, you pay for the call and get the information you need.
How your fax machine works
How a fax machine works is simple:
You put a page into your fax machine’s feeder and call a fax number. Your machine makes a satisfactory connection with the other machine, and then …
•Your machine takes the document.
An image scanner in your fax machine examines the information on the page.
•Your machine wraps the document.
Your fax machine translates the scanned information into a numeric code and compresses the code for the fastest possible transmission speed.
•Your machine sends the document.
Finally, your fax machine sends the compressed code.
On the other end of the line …
•The remote fax machine receives the code.
•Your machine unwraps the document.
The remote fax machine uncompresses and deciphers the code, turning it into a representation of the scan your machine made.
•The remote fax machine prints the representation.
The only difference between a regular telephone call and a fax call is the content of the transmission:
•On a regular call, your telephone sends your voice.
•On a fax call, your fax machine sends a coded image.
The way fax machines work is regulated closely by the International Telecommunications Union (ITU), an agency of the United Nations. The standards the ITU applies ensure the compatibility of your fax machine with millions of other machines
