line verification
In a public switched telephone network, a network-provided service feature that permits an attendant to verify the busy or idle state of station lines and to break into the conversation. Note: A 440-Hz tone is applied to the line for 2 seconds, followed by a 0. 5-second burst every 10 seconds, to alert both parties that the attendant is connected to the circuit.
