PBX FIELD DISPLAY ABSTRACT OF THE DISCLOSURE A PABX control circuitry housing which functions both as a housing for the circuitry and also as an indicator console, and can be mounted either on a wall or a desk top. To achieve a narrow, inobtrusive cabinet which can be used in this way, printed circuit boards are mounted parallel to the front of the housing. Indicators such as light emitting diodes (LEDs) are mounted along one edge of each of the printed circuit boards retained within the housing. The printed circuit boards are retained on successively stepped ledges, which causes the edges containing the LEDs on each of the boards to be visible from the front of the housing. A darkened, preferably translucent window in the housing allows the operator to view the LEDs. A silk screened or other imprint on the window provides the operator an indication of the meaning of the lit LEDs.
