• Hello protocol failures (this count is included as a component of the automatic line switches initiated
by protection-line switch counter)
• APS mode mismatch failures (occurs when the ADM indicates that it is provisioned for the 1:n APS
architecture, or when the ADM indicates that it is provisioned for unidirectional-switching mode)
• Protection switching byte failures (occurs when the received K1 byte is either inconsistent or
contains an invalid request code)
• Channel mismatch failures (occurs when the channel number in the transmitted K1 byte does not
match the channel number in the received K2 byte)
• Far-end protection line failures (occurs when a signal fail request code is received on the protection
line)

• Current contents of received K1 and K2 bytes

• An indication of whether an APS mode mismatch failure is currently active
