1.1 General Features
Data Line Security
Description
Data Line Security is a function that can be set by System Programming. Once set,
communication between the extension and the other end is protected from any signal such as
Call Waiting, Hold Recall and from Executive Busy Override. Data equipment or a facsimile
may be connected to an extension jack so that the user can perform data communications.
During the communication, Data Line Security maintains secure data transmission against
tones or barging in from other extensions.
Conditions
• Assigning Data Line Security always offers conversation privacy.
• If one extension in a conversation has set Data Line Security, it applies to the both
extensions.
• The Intercept Routing No Answer (IRNA) feature is not available for incoming calls to the
extensions to which the Data Line Security feature is assigned.
