The system has been exposed to ACS interference, described here. The <type> field is a string consisting of the single-character constants for each class of interference, concatenated together. For practical reasons, these are indicated based on the types of function impairment they cause.

class	effects
M	Impairment of motor control
C	Impairment of cortex operation
S	Impairment of sound (speech) output
N	Impairment of sensory functions
Y	Impairment of memory access

For example, a type of "MCY" indicates that motor control, cortex operation, and memory access are all impaired. At the conclusion of interference, "interference-state " is sent, with a trailing space.
