Glossary
If the machine is connected to a switching hub, it may not be able to connect to a
network when it is powering ON. This occurs because the spanning tree process,
performed between switching hubs, prevents them from communicating with each
other immediately after the machine connects to the network. A delay in the startup
time is necessary for the machine to connect to the network properly.
Subaddress is the global telecommunications standard specified by the ITU-T
(International Telecommunication Union-Telecommunication Standardization Sector).
When the remote party's machine supports the same standard, confidential or
relayed communications are possible by attaching a subaddress and a password in
advance.
The main Address Book is subdivided into 10 smaller address books, which are
considered subaddress books.
A portion of a network, which may be a physically independent network segment, that
shares a network address with other portions of the network, and is distinguished by
a subnet number.
For example, all devices with IP addresses that start with 255.255.255. would be part
of the same subnet.
The method used to determine to which subgroup, or subnet, an IP address belongs.
On TCP/IP networks, all devices whose IP addresses have the same prefix belong to
the same subnet. Dividing a network into subnets is useful for both security and
performance reasons.
A resolution mode for sending originals at four times the detail of the Standard
resolution mode. If the receiving machine does not support this mode, the document
is automatically sent in the Fine mode.
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.
