J1: Trace. Available when the Trace format is set to 1 Byte (refer to
Traces (SONET/SDH) on page 374).
SONET: The J1 Trace byte provides a 16 or 64 byte fixed string to verify
connection between path transmitting equipment and path receiving
equipment.
SDH: The higher-order (AU)/low-order (TU) VC-N path trace byte
provides a 64 byte fixed string to verify connection between path
transmitting equipment and path receiving equipment.
B3: BIP-8. The BIP-8 (Bit-Interleaved Parity) byte provides path error
monitoring. The byte is calculated by performing a even-parity check
over all bits of the previous SPE.
