GLOSSARY 171
Routing
Determining the path that a
message or call has to take
over circuits. TalkSwitch offers
‘routing’ of incoming calls
using DSP (Display System
Protocol) technology.
Serial Communication
A type of electronic
communication requiring data
bits to be sent one after the
other, unlike parallel
communication. Modems rely
on serial communication to
send data over telephone lines.
Shortcut Key
A special key combination that
causes a specific command to
be executed. Typically,
shortcut keys combine the Ctrl
or Alt keys with other keys. In
Windows environments, Ctrl
and C is the shortcut key to
copy. On PCs, the function keys
are often also used as shortcut
keys.
SIP
Session Initiation Protocol —
It is a signaling protocol,
developed by the Internet
Engineering Task Force (IETF),
designed to be much more
simple and flexible than the
H.323 protocol. SIP uses the
existing Internet and HTML
structures to provide VoIP
transmissions. In addition, SIP
is more scalable, allowing
applications to grow in scope
without any concern for the
existing architecture. SIP gives
network managers the
flexibility to select any type of
architecture, from a heavily
centralized network controlled
extensively by a server, to a
less concentrated network
where intelligence is found at
the endpoints that
communicate directly with
each other.
Serial Port
Serial Ports are physical ‘plug-
ins’. They allow two devices to
exchange information or data.
A Serial cable connects the two
Serial Ports together.
SOHO
Small Office/Home Office —
It’s a burgeoning market
comprised of solo
professionals, part-time work-
at-homes, telecommuters and
small businesses.
