OH - SONET/SDH
If the signal label in V5 (bits 5, 6, and 7) is 101 the contents of the
extended signal label is valid and contains in a 32 bit multiframe as
shown below. See Z7/K4 Structure shown below.
Z7/K4 Structure
J2 Trace. Available when the Trace format is set to 1 Byte (refer to
Traces (SONET/SDH) on page 198).
SONET: VT Path Trace: The J2 Trace byte provides a 16 or 64 bytes fixed
string allowing the receiving VT PTE to verify its continued connection
to the intended transmitting VT PTE.
SDH: Path Trace: The J2 byte is used to repetitively transmit a
Lower-Order Access Path Identifier so that a path receiving terminal
can verify its continued connection to the intended transmitter.
Z6/N2
Z6 (SONET): VT Tandem Connection Monitoring or VT Path Growth.
The Z6 byte is allocated for future growth.
N2 (SDH): (Network operator byte) Tandem Connection Monitoring for
the VC2, VC-12, and VC-11 level.
