Abstract

A telephone includes means for switching the LEDs, on the face of the phone, between a normal operating mode in which the lights indicate the status of telephony features, such as mute or hold, to a diagnostic operating mode in which the LEDs indicate the status of the telephone's data communications signals. The modes are toggled by entry of a code on the telephone keypad or by way of a command from a workstation coupled to the telephone by way of a data communications port.
