telephone lines and calling features is
controlled internally within each tele-
phone unit. Users can gain direct access
to telephone lines, etc. by pressing a key
(or button) on their telephone.
LED
Light Emitting Diode. An electronic
device that lights up when electricity is
passed through it. LEDs are used in dis-
plays on electronic devices such as com-
puters. TalkSwitch has five LEDs on its
front panel. They show which telephone
is in use, whether data is being trans-
ferred to or received from an attached PC,
and which Mode setting is in use.
Link button
On most telephones, pressing the Link
button has the same effect as pressing the
Flash button or depressing and releasing
the 'hang up' (switch) hook. However, on
some telephones, the function of the Link
button is internal to the telephone and
pressing it will have no effect on
TalkSwitch.
