134 TalkSwitch User Manual
Firmware
Firmware is a combination of software
and hardware. More precisely, it is
software (programs or data) that has
been written onto hardware
(micro-chips). Micro-chips (ROMs,
PROMs and EPROMs) that have data or
programs recorded on them are called
firmware.
Flash button
A button on your telephone. Pressing the
Flash button has the same effect as press-
ing the Link button or depressing and
releasing the 'hang up' (switch) hook on
a telephone. All of these actions will send
a signal to TalkSwitch to put calls on or
off hold.
Flash EPROM
TalkSwitch's firmware program (the
programming code that operates
TalkSwitch) is located on a 'Flash
EPROM' chip. This means that the code
operating TalkSwitch can be erased and
reprogrammed (upgraded) without
replacing the chip that contains the code.
Home phone
A home phone is any telephone using the
same telephone line as one of
TalkSwitch's Lines, but is not plugged
directly into the back of TalkSwitch as an
extension.
Icon
A small picture that represents a
program, action or feature in the
Configuration Software. When you click
on an icon, that program, action or
feature is activated.
Auto Call Back
Allows you to activate Call Back by
dialing one of TalkSwitch's telephone
numbers, letting the call ring at least
once and then hanging up.
Intercom
A dedicated voice service within a
specified user environment. TalkSwitch
offers intercom capabilities between its
Local Extensions.
Interface
Something that connects two separate
entities. A user interface is the part of a
program that connects the computer with
a human operator (user).
Internet
A global network connecting millions
of computers. Unlike online service
networks (.com, .ca, .net, etc.) which are
centrally controlled, the Internet is
decentralized by design. Each Internet
computer, called a host, is independent.
IRQ
Interrupt Request Line. Hardware lines
found in PCs over which devices can send
interrupt signals to the microprocessor.
IRQs allow multiple devices attached to
your PC to share the micro processors
resources in an orderly fashion. When
you add a new device to a PC, you
sometimes need to set which IRQ
number the device will use.
ISDN
Integrated Services Digital Network. The
same lines are used for many different
types of services, such as telephone, data,
electronic mail and facsimile. ISDN
specifications let large quantities of data
(wide-bandwidth) flow from one location
to another using the public telephone
network. Under ISDN, a phone call can
transfer 64 kilobits of digital data per
second.
Keypad Commands
Combinations of digits that are used to
configure TalkSwitch from a touchtone
telephone.
