A count of Channel Mismatch failures. A Channel Mismatch
indicates that a mismatch between the transmitted K1 channel and
the received K2 channel has been detected. Under normal
conditions, a mismatch will occure each time the LTE changes the
channel number on its transmitted K1 byte (i.e., when the
channel with the highest priority switch request changes). A
mismatch could also occur if the channel number on the incoming
K2 byte changes (e.g., due to a failure at the far-end LTE).
