Data Line Security
Description
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.
