SONET/SDH STS-48c/STM-16 Concatenated Path/Pointer Processor

Features

• Suitable for FPGA and/or ASIC implementations.
• Supports bypass and normal (path overhead processing/pointer processing) modes of operation.
• Implements 16-bit register interface for programming of internal registers.
• Supports path and pointer processing for concatenated payload types.
• Provides transmit facility and terminal loopback options for diagnostic purposes.
• Inserts high order path overhead through internal register programming and/or an external overhead port.
• Provides automatic path REI insertion (bit or block mode options) for B3 parity errors detected in the Receive Processor.
• Allows for the insertion/extraction of programmable 1, 16 or 64 byte trace messages.
• Extracts high order path overhead information to internal register locations and an external path overhead port.
• Includes 16-bit saturating performance counters (configurable for bit or block type) for the accumulation of B3 errors with programmable threshold capability.
• Provides optional interrupt generation for B3 error, signal degrade (SD) and signal fail (SF) detection.
• Provides pointer interpreter functionality with programmable state machine operation including the 8 of 10 pointer objective and single AIS state transition options for flexible configurations.
• Detects and accumulates pointer interpreter or pointer generator increments, decrements, and NDF events.
• Interprets incoming path RDI overhead information (provides programmable accept and unstable counts) and provides detection of RDI-P, ERDI-P, and path RDI unstable errors with maskable interrupt capability.

Benefits

• Xelic cores are optimized to keep resource utilization low enabling designers to include more functionality in a single FPGA implementation.
• Xelic offers flexible licensing terms with single use, source code options available.

Deliverables

• Xelic cores come complete with a database which contains a verification environment (generators, checkers, models, etc), an extensive suite of self checking tests, synthesis scripts, and a comprehensive set of core documentation (product brief, datasheet, fact sheet, etc.).
