Monolithic SATURN-Compatible SONET/SDH Asynchronous Transfer Mode User Network Interface for LAN, Public UNI, and Public NNI connections.
Implements the ATM transmission convergence (TC) sublayer for ATM according to ITU-T and draft ATM Forum recommendations using the SONET/SDH 622.08 Mbit/s and 155.52 Mbit/s format.
Also supports the SONET 51.84 Mbit/s format.
Processes all SONET/SDH UNI overhead.
Inserts and extracts ATM payloads using cell delineation.
Provides a SCI-PHY compliant 50 MHz synchronous 16-bit 4 cell deep FIFO buffers in both transmit and receive paths.
Compatible with ATM Forum Utopia interface format, with support for multi-PHY applications.
Provides access to section and line data links and all additional overhead to allow external processing for full SONET/SDH Network-Node Interface (NNI) compliance.
Provides a generic 8-bit microprocessor bus interface for configuration, control and status monitoring.
Provides a standard 5-signal P1149.1 JTAG test port for boundary scan board test purposes.
