Abstract
An indicator for use with a multiline telephone, which displays the status of both a local and called telephone set. The status indicator is comprised of a first indicator enclosed within a second for displaying by a shade or color the status of a called line, and a second indicator at least partly surrounding the first for partly displaying the first for displaying by shade or color with the second indicator the status of the calling line, whereby a party observing the indicator obtains simultaneous indication of the status of the calling and the called lines. Preferably the first indicator is a circle, enclosed within the second indicator which is a square, both being elements of a liquid crystal display. Each square indicator can be located next to a line access pushbutton with which it is associated.
