A count of APS Mode Mismatch failures. An APS Mode Mismatch is
a conflict between the current local mode and the received K2
mode information. An LTE in a mode other than 1+1
unidirectional must monitor the mode of operation indicators in
the incoming K2 byte of the protection line for APS Mode
Mismatch failures. K2 bit 5 indicates the architecture; K2 bits
6-8 indicate if the mode is unidirectional or bidirectional.
