The INM Equivalent Inp histogram since last link up. An array of 68 octets
(each 4 octets means amount of a bin of histogram), designed for supporting
from 1 to 17 bins of the histogram. The particular index of the bin incremented
by an impulse noise event is equal to the computed value of equivalent INP,
except the 17th of anomaly INPEQ, which logs all equivalent INPs greater than 16.
Each bin has a value in the range 0x0 to 0xFFFFFFFF
