J1: Trace. Available when the Trace format is set to 1 Byte (Refer to
Traces (SONET/SDH) on page 162).
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) 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.

C2: Signal Label. Entering a C2 byte value will automatically update the
Path Signal Label (C2) selection and vice versa. Refer to
STS/AU Path (C2) on page 96 for more information.
