S/UNI
The S/UNI is a monolithic integrated circuit that implements the SONET/SDH
processing and ATM mapping functions of a 155 Mbit/s SONET STS-3c User
Network Interface. It is the heart of the SAPI-UTP5 board; all traffic goes through the
S/UNI. On the line side, the S/UNI transmits SONET frames through the line
interface and receives frames from the line interface. On the drop side, the S/UNI
