IBM SONET/SDH Framer  
- Debounced K3 byte plus New K3 indication.  
- G1 path REI (Path FEBE) plus Path RDI.  
- M1 Line REI (Line FEBE) and Line RDI.  
• The SONET/SDH framer will not lose data input on its transmit ring port interface if the frequency of its  
transmit ring port clock input signal is 20 ppm from nominal and its transmit line clock is 20 ppm from  
nominal. This also applies to the receive side. That is, if the receive line frequency is different from the  
RXRINGCLK frequency, then no data will be lost going from the receive side of the SONET/SDH framer  
over to its receive ring port interface.

Address Field Bit Definitions indicates the meaning of the bits in the address field while the five figures that  
follow it indicate the formats of the nine-bit data field. The data fields contain information relating only to their  
corresponding STM-1/STM-4/STM-4c/STS-3c/STS-12/STS-12c.
