MBX IP Description / Operations & Programming Guide
Automatic Privacy/Branch Line
Privacy is insured in all communications on the system. If desired, the customer may elect to
disable the Automatic Privacy feature, allowing an uninvited station to join in an existing
external conversation. In such a case, a conference is established. The Privacy feature
restricts the intrusion/call-wait/camp-on/OHVA at a busy station, while the Branch Line can
restrict a conference call by pressing {DN} button in use.
CONDITIONS
- With Automatic Privacy disabled, privacy is still assured on all intercom and
conference calls.
- Only one station can intrude on an active call.
- An intrusion tone can be provided to the call indicating another station has accessed
the line.
OPERATION
Digital Phone
To intrude into a call when Privacy is disabled:
Make a call to busy station and then press the appropriate code for

To change privacy mode in conversation:
Press the {DND} button during a conversation.
To intrude in a call when Branch Line is enabled:
