Value (Bits
1...8)
Used to continuously send a repeating Trace Message which may be 16
octets (or 64 octets, see Section 7.3.7 Extended J1 Trace Messaging (64
bytes)) in length. This information is obtained from the Layer Management
block.
Used for path error monitoring functionality. This is a bit-interleaved parity-8
code using even parity and is calculated over all bits of the previous STS-
192c SPE before scrambling.
Identifies the construction and content of the STS-192c SPE as a 10 Gigabit
Ethernet stream.
Used to convey back information regarding status and performance to an
originating STS-192c PTE.
Bits [1...4] - Remote Error Indication (REI) - These four bits count the
number of B3 errors that have been detected. There are nine legal values
which are 0000, 0001,0010,0011, 0100, 0101, 0110, 0111, 1000. Any other
value will be interpreted by the originating PTE as 0000.
Bits [5...8] - Remote Defect Indication (RDI) - These bits are used to convey
error information to the remote PTE.
