Just in case …
The way fax machines work is regulated closely by international standards applied
by the International Telecommunications Union (
ITU
), an agency of the United
Nations. These standards ensure the compatibility of your fax machine with mil-
lions of other fax machines worldwide. However, they also limit the way you can use
your machine with a second telephone.
Nonetheless, this is a small price to pay — for the ability to send documents just
about anywhere on earth!
