SDH - Regenerator Section Overhead (RSOH)

SDH - Regenerator Section Overhead (RSOH)
The section contains regenerator section overhead information (RSOH)
used by all SDH equipment along a network path, including signal
regenerators.
A1 and A2: Framing
A1 and A2 indicate the beginning of the STM-N frame. They must appear in
every STM-1 of a composite signal. The value in hexadecimal is F628.
J0: RS Trace Message
The J0 (Trace) byte is used to trace the origin of an STM-1 frame as it travels
across the SDH network. This byte is only defined for the first STM-1 of an
STM-N signal.
Z0: Growth
These bytes are reserved for future international standardization. They are
located at positions S[1,6N+2] to S[1,7N] of an STM-N signal (N > 1).
