R/W Description
CDT_10m_Short
RO
1 = Less than 10 meter short.
Cable Diagnostic Test Results
[00] = Normal condition.
RO [01] = Open condition has been detected in cable.
[10] = Short condition has been detected in cable.
[11] = Cable diagnostic test has failed.
Cable Diagnostic Test Enable
1 = Cable diagnostic test is enabled. It is self-
RW/
cleared after the test is done.
SC _{0 = Indicates that the cable diagnostic test has}
completed and the status information is valid for
reading.
Force_Link
RW 1 = Force link pass.
0 = Normal operation.
RW Reserved
Remote (Near-End) Loopback
RW
1 = Perform remote loopback at port 1's PHY
(RXP1/RXM1 -> TXP1/TXM1)
0 = Normal operation
CDT_Fault_Count
RO _{Distance to the fault. It’s approximately}
0.4m*CDT_Fault_Count.
