Glossary
K
Front Panel
The front panel on the ZyXEL modems consists of LED indicators.
FSK
Frequency Shift Keying - a frequency modulation scheme.
Full-duplex
Full duplex is a transmission link where transmission can take place in both
directions simultaneously.
G3 Fax
Several fax standards exist. Most available fax machines use the Group 3 (G3)
standard. This standard defines the compression of graphic data and a
transmission speed of up to 14400 bps with an automatic fallback to 2400 bps if
the telephone line is bad.
Gateway
A gateway is a computer system or other device that acts as a translator
between two systems that do not use the same communication protocols, data
formatting structures, languages, and/or architecture.
Handshake
At the beginning of a connection, the modems must negotiate and initialize the
protocols to be used and the speed at which the connection is to be
established. This negotiation phase and the following initialization phase is
called handshake.
HDLC
HDLC (High-level Data Link Control) is a bit-oriented (the data is monitored bit
by bit), link layer protocol for the transmission of data over synchronous
networks.
High-speed
Modem
A modem that works at bit rates higher than 9600 bps.
Hook-Flash
The hook-flash is a signal used in a dial sequence. This signal may be used for
call transfers or to request an outside line on certain PABX.
Host
Any computer on a network that is a repository for services available to other
computers on the network. It is quite common to have one host machine
provide several services, such as WWW and USENET.
HTTP
HyperText Transfer Protocol is the most common protocol used on the Internet.
HTTP is the primary protocol used for web sites and web browsers. It is also
prone to certain kinds of attacks.
Hz
Hertz. A unit of measurement for frequency. Cycles per second.
Inside Wiring
Wiring that is done from the point of demarcation to the jack in the wall where
the line terminates.
