GENERAL DESCRIPTION OF A FACSIMILE

2–4

Fig. 2-1   Analog Line and Digital Line

In Japan, there are lines exclusively for facsimile communications called

Facsimile communication network services.  As a facsimile does not hold

conversations simultaneously like a telephone, the facsimile adopts a

method of storing the documents to be transmitted on the network, and

then transmitting them at once using a high-speed line. By this method, the

line is separated from the facsimile after the document is stored, to ensure

efficient use of the line. For this reason, you are charged by the number of

document sheets that you transmit regardless of the transmission time.
