PM5543 SARD
SONET/SDH 155Mbit/s ADM Reference Design
FEATURES
• Receives an OC-1/OC-3 optical signal and processes section, line and path
SONET overhead.
• Performs arbitrary tributary cross-connection to produce a byte serial STS-1, STS-3
(STM-1, AU3), STS-3c (STM-1, AU4) signal.
• Transmits an OC-1/OC-3 [STS-1/STS-3 (STM-1)] stream with an option to
overwrite all section, line and path overhead.
• Provides for loop back of both line-side and drop-side signals.
• Recovers line-side receive signal clock.
• Drop-side receive clock may be pleisiochronous to the line-side receive clock.
• Provides on board line-side transmit clock synthesis.
• Drop-side transmit clock may be pleisiochronous to the line-side transmit clock.
• Optionally translates received pointer justification events at the SPE level to
tributary pointer justifications, thus locking the SONET SPE to accomplish tributary
switching.
• Optionally cross-connects tributaries mapped in the receive stream to any arbitrary
time slots in the drop-side stream.
• Allows broadcasting of tributaries over multiple tributaries.
• Provides line side OC-1/OC-3 transmit and receive signals on SC type optical
single mode connectors.
• Provides an interface to a proprietary external mapping-demapping function via a
100-pin connector.
• Provides a 100-pin connector for ring expansion and ring control for connection to
another PM5543 SARD board.
• Provides a 132-pin connector for microprocessor interface to a PM1501 EVMB
motherboard.
