CX29600 Data Sheet
RXPTHBUF (Receive Path Trace Circular Buffer)
The RXSECBUF buffer is used to repeatedly receive a 64-byte, fixed-length string so a receiving terminal in a
path can verify its continued connection to the intended transmitter.
RXRDI (Receive RDI-P Status Register)
The RXRDI register contains the received bits of the G1 octet.
RXS1 (Receive S1 Line Overhead Status Register)
The RXS1 register contains the received S1 Line Overhead byte. This byte is allocated for transporting
synchronization status messages. This byte is defined only for the first STS-1 of the STS-3. These messages
provide an indication of the quality level of the synchronization source of the SONET signal.
