0x68—TXSECBUF (Transmit Section Trace Circular Buffer, J0)
The TXSECBUF buffer, the J0 byte, is used to transmit repeatedly a 64-byte, fixed-length string so that a
receiving terminal in a section can verify its continued connection to the intended transmitter. This buffer is also
used as a Section trace for SDH.
