and duplex mode to the highest level that the opposite site device both
support according to the bit rate and duplex mode adopted by the remote
site device, that is, the connected devices on both site adopt the fastest
transmission mode they both support after the auto negotiation process.

APS is used to monitor transport lines in real time and automatically
analyze alarms to discover faults. When a critical fault occurs, APS can
make the working channel switched to the protection channel quickly to
recover communication in a very short period.
Connectivity Fault Management (CFM) is end to end service-level
