The set of standards for digital transmission of data over standard copper telephone lines is ISDN

Yes, you will be charged on your phone bill for any long distance calls you make from your fax machine, at exactly the same rate you would be charged for calling the same number from a landline phone at the same location. Your fax machine is basically a specialized telephone that encodes an image (your document) into sounds that are sent over an ordinary telephone call.
A telephone can be considered both a machine and a tool. It is a machine because it is a device with moving parts that performs a specific function of transmitting sound over distances. It is also a tool because it is used by individuals to communicate with others over long distances.
Telecommunication over telephone networks.
Integrated service Digital network. ISDN is a circuit-switched telephone network system, that also provides access to packet switched networks, designed to allow digital transmission of voice and data over ordinary telephone copper wires, resulting in better voice quality than an analog phone. It offers circuit-switched connections (for either voice or data), and packet-switched connections (for data), in increments of 64 kbit/s. Another major market application is Internet access, where ISDN typically provides a maximum of 128 kbit/s in both upstream and downstream directions (which can be considered to be broadband speed, since it exceeds the narrowband speeds of standard analog 56k telephone lines). ISDN B-channels can be bonded to achieve a greater data rate, typically 3 or 4 BRIs (6 to 8 64 kbit/s channels) are bonded.
ISUP is also known as ISDN User Part. It is part of Signaling Sysytem #7 which is used to set up telephone calls in networks. It plays an important role when a call between two mobile subscribers involves two or more telephone switches.
ISDN stands for Integrated Services Digital Network. It is a type of digital telephone network that allows for voice, data, video, and other services to be transmitted simultaneously over a single line.

ISDN ISDN or Integrated Services Digital Network was designed to be integrated into current digital telephone services and was originally designed to bring high speed voice and data to home users.
It is the abbreviation for Integrated Services Digital NetworkViper1A wide area network (WAN) oriented data communication service provided by telephone companies JunkCollectorISDN(Integreted Service DIgital Network)is an technology that provides simultanous transmission of data + voice over a single channel or wire. DSL and ADSL modems best describes its application in action. For furtther rfrence yo can go to:- http://en.wikipedia.org/wiki/ISDN. Raj_halcyon
A telephone is a machine that helps us talk as it allows us to communicate with others over a distance through voice calls.
