Telephony Application Programming Interface - Microsoft's and Intel's
method of integrating telephone services and computers so that your
computer can control your telephone. TAPI allows you to screen dial,
Transmission Control Protocol/ Internet Protocol. The family of protocols
used on the internet and some corporate networks.
Also known as MF (multi-frequency) or DTMF (dual tone multi-frequency).
A dialling method which generates audio tones when digits are dialled.
These tones are sent down the line and can be detected by telephone
systems or other devices.
A line connecting a telephone system to another telephone system or to
the Public Switched Telephone Network (PSTN).
A facility which allows an incoming call received on one line to be transferred
to someone on another line, i.e. both callers are external to the telephone
system. Typical uses include transferring an incoming caller to someone's
Telephony System Application Program Interface. A standard devised by
Novell Corporation for communication between a network server and a
telephone exchange. Because it is working at a system level this offers
more flexibility than TAPI but is also more complex to implement.
A facility of voicemail systems and answering machines which allows both
sides of a telephone conversation to be recorded for later playback.
Unshielded Twisted Pair. A type of cable. Commonly (and imprecisely)
used to differentiate from computer cables using co-axial cable such
as 10 Base 2, Thin Ethernet, Thinnet, Thick Ethernet, Thin Ethernet
or IBM Twinax.
A voicemail system typically provides central "answering machine" for
users of a telephone system. The user diverts his calls to the voicemail
system, which will play a personalised message to a caller and allow
him to leave a message for the extension user. Most voicemail systems
also provide options for routing callers to departments or extensions
and for giving out information to callers.
Voice over IP - telephony over the internet or local area network.
Wide Area Network - A network, usually constructed with serial lines,
extending over distances greater than one kilometre.
Wireless Access Protocol. A means of accessing the Internet using a mobile
term relating to LAN connectivity without wires.
Wireless LAN - A LAN that connects to your existing ethernet.
Windows Operator Console.
eXtra Device Port.
A term used on the Panasonic KX-TD range of digital telephone systems.
Each extension port on the system will support a digital keyphone and
an analogue phone at the same time and on the same extension number.
For example a keyphone will sit on the desk with a cordless phone alongside.
Either can be used. They both have the same extension number. When XDP
working is enabled in programming they become separate extensions with
different numbers, allowing for example the user to be talking on the
phone while using a modem to get his e-mail. When XDP is enabled separate
sockets can be wired for the digital and the analogue ports, allowing
the system size to be doubled. For example a 32 extension system could
have 32 digital extensions as well as 32 analogue extensions, all independent
of each other using XDP working.
