Super G3
Super G3 is a phrase used to describe the generation of fax machines that use ITU-T
V.34 standard 33.6 Kbps modems. Super G3 high-speed fax machines allow a
transmission time of approximately three seconds per page, which results in reduced
telephone line charges.
Switching hub
A network connection box to which a number of computers can be connected.
Conventional hubs send each data packet to every connected computer on the
network, whereas a switching hub forwards data packets from the network to the
appropriate computer, according to the packet's address. Since a switching hub
forwards packets only to their intended recipients, it provides greater efficiency.
T
TCP/IP
Transmission Control Protocol/Internet Protocol. The protocol used to connect to the
Internet and wide area networks.
Telephone Line Type
Depending on the type of phone line that you have, set the machine to touch tone (T)
or pulse (P) dialing.
TIFF
Tagged Image File Format. A file format that saves images as high-density bitmaps,
and is suitable for large amounts of image data. The information field (tag) at the start
of each image data record indicates the type of data represented.
Token Ring
A local area network system developed by IBM, in which conflict during message
transmission is avoided by granting "tokens" that allow computers to send messages.
The system can transmit data at 4 or 16 Mbps.
Tone
Some data services may require that you use tone dialing. If you have a pulse dial
telephone, press [Tone] to switch temporarily from pulse to tone dialing when
connecting to these data services.
Transmission Time
A fax transmission consists of three stages: the machine sending the fax connects
with the machine receiving it, the message is then transmitted, after which the sender
and the receiver exchange signals to confirm the end of transmission. The
transmission time described in this guide is not the total time required for the entire
transmission, but only the time taken for the message to transmit.
