Aligns incoming SONET/SDH frames and provides transport overhead processing, path overhead processing and pointer processing for contiguous concatenated SONET/SDH payloads types. Contains independent Transport Processor and Concatenated Path Processor modules with optional dedicated external ports for overhead insertion and extraction. Incoming/outgoing data is transferred at an STS-3c/STM-1 rate using an 8-bit data bus operating at 19.44Mb/s.
关键特性
- Compliant with ITU-T G.707 and Telcordia GR-253-CORE specifications
- Implements optional, 16-bit register interface for programming internal registers
- Inserts/extracts high order path overhead through internal register programming and/or optional external overhead port
- Allows for the insertion/interpretation/acceptance of programmable 1, 16 or 64 byte trace messages w/programmable unstable and accept counts
- Programmable auto insertion line/path RDI; diagnostics - force line/path AIS, LOS, RDI, frame corruption
- Saturating performance counters for B1/B2/B3 errors, OOF, REI; optional interrupts for signal degrade/signal fail
- Feature programmability can be easily optioned away for slice count reduction
