2.5G to 400G GMP Mappers

Overview

Key Features

• CBR Mapping of client payload into ODTU.ts
• Support up to 80 ODTU.ts (channels) each at ODU0 rate (in ODUk) or Support up to 10 TS each at ODUC 100G slicer.
• Support per tributary slot client clock
• Client side interfacing with internal asynchronous FIFO
• Line side interfacing with ODU layer interface
• Optional generic 32-bit CPU interface
• Seamless integration with Precise-ITC OTU digital wrapper at line side
• Easy to customize for specific applications
• Source direction
• Programmable OPU AIS (all 1s) generator per tributary slot (or channel) at source direction
• Client signal fail (CSF) detection at source direction
• Support internal Cm adjustment algorithm with fully software tunable parameters
• Support external Cm adjustment algorithm or software driven Cm
• Support software programmable OPU payload type (PT) byte and MSI bytes
• Sink direction
• Support software pre-define expected PT byte, MSI bytes
• Support OMFI sequence checker
