The Xilinx GFP core solution fully implements the International Telecommunication Union’s Generic Framing Procedure recommendation (G.7041/Y.1303). All protocols defined by the ITU’s Telecommunication Standardization Sector (ITU-T) are supported, including Ethernet, PPP, RPR, GE, Fibre Channel, FICON, ESCON, and DVB-ASI. The GFP core includes the capability to perform end-to-end frame delineation, and supports both client management and data frames. The GFP core can be configured for frame-mapped, transparent, or mixed-mode operation on a per-channel basis, enabling multi-line, multi-service cards and systems in Ethernet-over-SONET or Data-over-SONET applications.

Key Features

• Fully compliant with ITU-T G.7041 GFP recommendation
• Supports frame-mapped, transparent, and mixed-mode operation
• Supports both null and linear frames, enabling one to ten unique channels
• Enables multi-line/multi-protocol MSPP's, i.e. 10x 1-GE => OC-192
• Individually optimized for OC-48 or OC-192 applications
• Supports both client data frames and client management frames
• Supports dynamic reconfiguration, error insertion, and status monitoring via host interface
• Separate MAP and UNMAP cores support unique ingress/egress path requirements
• Utilizes Xilinx standard LocalLink interface for easy integration
• Fully configurable using the Xilinx CORE Generator tools
