Data Line Security

Data Line Security
Data Line Security protects any station port from receiving audible tones (such as Camp-On or Override) and denies a station from barging in while busy to prevent disruption of data transmission when using a modem or facsimile machine.
Conditions
• When a Multiline Terminal and a Single Line Terminal are assigned for Data Line Security, Tone Override/Voice Override and Call Alert notification tone are not heard over the handset speaker.
• Data Line Security protects a station from Barge-in, even when Barge-In is allowed in Class of Service.
• When any Multiline Terminal or Single Line Terminal calls a station with Data Line Security, a constant busy tone is heard.
