Break-in
The Meridian attendant can use the break-in feature to interrupt an on-going call from a telephone
in the Business Communications Manager system.
The following figure demonstrates the call path for a Meridian attendant to break into a call
between telephones in the Business Communications Manager system.
Figure 194 Breaking into a Business Communications Manager call path
Break-in can occur when these situations are valid:
• Target Business Communications Manager telephone is busy but still has a free intercom or
line key.
• There is no camped call on the target telephone.
• DND on busy is turned on.
• prime set is also busy, with no free key, and with DND turned on.
• Attendant capability is high (2), and higher than either the target telephone or the caller the
target telephone owner is busy with.
Only post-dial break-in is supported by MCDN:
1 Attendant dials destination number.

If a busy tone is heard, the attendant presses the BKI button.
Attendant is given access to the conversation.
You can set a level of priority that will determine if a telephone will allow an attendant to break in.
This is referred to as setting the Intrusion level. Use the following rules to configure the break-in
feature.
• Set the Intrusion level for each telephone (under Capabilities). Refer to “Setting intrusion
controls” on page 426 .
