Executive intrusion, Intrusion protection level

Executive Intrusion (EI) is a DPNSS 1 feature that allows an operator, or other calling party, to
intrude on a line when it is busy. An example of the use of this feature is to make an important
announcement when the recipient is on another call.
EI is implemented on the BCM using Intrusion protection level (IPL). IPL has four settings, from
None to High. A telephone set has the ability to break-in when the other telephone set has a lower
IPL. The default setting is None and a setting of High prevents intrusion.
Restrictions by telephone type
• ATA2/ASM8+—supported
• ISDN—not supported
