Data Communications Channel (DCC) Bytes (D4-D12)
DCC – together these nine bytes form a 576kbps message channel for OAM purposes.
They can be used for internally or externally generated messages or BER function.
S1 Byte (Synchronization Status)
Synchronization status message byte contains information about the quality of the embedded timing and is used
to inform the remote Multiplexer of the clock quality used to generate signals.
Bits 1-4 carry synchronization messages
Bits 5-8
0000 Synchronized - Traceability Unknown
0001 Stratum 1
0100 Transit Node Clock
0111 Stratum 2
1010 Stratum 3
1100 SDH Minimum Clock
