A device (20) and method which make use of an indicator (90) adapted to display the connection status of a call-waiting feature subscriber are disclosed. The indicator (90) indicates a first connection status (120) when the subscriber is actively connected to a first calling party, and inactively connected to a second calling party (i.e., the second caller is waiting for an active connection, or has been placed on hold). The second connection status (100) is indicated when the subscriber is actively connected to the second calling party and inactively connected for the first calling party (i.e., the first call is on hold). The indicator (90) may be visual or aural. The indicator (90) may also take the form of a display (110), using various characters (112, 114) or caller identification information (170, 180). The indicator (90) is typically activated by a software/hardware module (95) within a telecommunications network which sends indicator signals to the subscriber Customer Premises Equipment (CPE) (20), such as a telephone or caller identification device. The indicator may also be activated by monitoring the flash (92) or switch hook (91) activity of the CPE (20).
