4.0 Registers
4.1 Memory Map
RXSEC (Receive Section Overhead Status Register)
The RXSEC register provides section overhead status.
RXSECBUF (Receive Section Trace Circular Buffer)
The RXSECBUF buffer, the J0 byte, is used to repeatedly receive a 64-byte, fixed-length string so 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.
RXZ1b (Receive Z1b Overhead Status Register)
The RXZ1b register contains the first received Z1 octet.
4-52
