SDH - Higher-Order Path Overhead (HP-POH)

SDH - Higher-Order Path Overhead (HP-POH)

This section contains higher-order path overhead information (HPOH)
processed by SDH STM-1 terminating equipment.

J1: Higher-Order VC-N Path Trace

The higher-order VC-N path trace byte provides a 64 byte fixed string to
verify connection between path transmitting equipment and path receiving
equipment.

B3: Path BIP-8

The path BIP-8 (Bit-Interleaved Parity) byte provides path error monitoring.
The byte is calculated by performing a routine even-parity check over all
bits of the previous SPE.
